Types and Features of Measurement Methods Section 1-2

1-2-2 Features of Measurement Methods

Area (Var. Box)

Use an area (variable box) measurement to adjust the measurement region (a box) for measurement objects with varying sizes or positions and find their size and center of gravity.

The upper, lower, left, and right edges of the measurement object are found.

Upper edge

Measurement region

SeeAlso Refer to page 7 for information on Gravity and Area.

Defect (Var. Box)

Left edge

Lower edge

With the edges detected, the F160 can determine where the measurement object is. Even if the size and position of the measurement object changes, the F160 can move the measurement region appropriately.

Once the edges have been found, the image is converted to a binary image and the area and center of gravity of the measurement region are found.

Use a defect (variable box) measurement to adjust the measurement region (a box) for measurement objects with varying sizes or positions and find defects.

The edges are found in the same way as for Area (var. box) and the measurement region is moved as required.

Once the edges have been found, the defects inside the measurement region are detected.

Right edge

Measurement region

SeeAlso Refer to page 9 for information on Defect.

Gravity and Area

Use a gravity and area measurement to find the size and position (center of gravity) of a measurement object.

Page 20

Types and Features of Measurement Methods Section 1-2

The image read by the Camera is a 256-gradation image. This is converted to a binary image made up of black and white pixels. The F160 focusses on the white areas only and performs measurement.

Types and Features of Measurement Methods Section 1-2

OCR for 1 Character

Use an OCR for 1 character measurement to recognize alphanumeric characters and special symbols. The F160 provides a dictionary, so no models need to be registered.

The F160 recognizes two candidates, 1st candidate and 2nd candidate, from the dictionary, that are most similar to the character image in the measurement region.

If the density deviation is not greater than the set value, the image is recognized as having no pattern (no detectable marks).

Measurement region

1st candidate: 5 2nd candidate: S

CHECK An expression can be set to output the character code of the recognized char-

acter to an external device. The output when no pattern is detected is the underscore (_) character code.

Classification

Use a classification measurement to classify products, for example, on a line for a variety of products.

A model is registered beforehand that will serve as the classification reference. Up to 36 types of models can be registered to index numbers 0 to 35.

When the printing quality or shape of the model is inconsistent, register multiple models to the same index number. Up to 5 models can be registered to the same index number.

A registered to 0 C registered to 2B registered to 1

CHECK When multiple models are registered to the same index number, the F160

automatically creates auxiliary models between the models that are registered. If the auxiliary models are added to the registered models when searches are performed, stable searches are possible even if there are variations between the registered models. You can select whether or not to use auxiliary models in searches. Refer to page 331 for information on auxiliary models.

The F160 outputs the number of the index for the model that most resembles the image. If there is no model that resembles the image, NG is output. Once that data has been received by the external device, the product can be classified at the next processing stage.

Searches for the model with the highest correlation.

CHECK Expressions must be set to output data to an external device.

Use a defect measurement to detect defects in unpatterned measurement objects.

This method checks for surface defects by measuring variations in density. The shape of the measurement region can be chosen from arc, box, circumference, or line.

ing measurement region sizes or positions.

Use a density data measurement to detect the presence of a measurement object.

Example: Detecting the Presence of Electronic Parts

Set two measurement regions, one for the part location and one for the background. The density average of each is measured and the difference is used to check if the part is present. If the part is present, the density difference with the background will be large. If the part is not present, the density difference will be small.

Page 23

Types and Features of Measurement Methods Section 1-2

The difference in density is compared, so there will be little influence on the measurement if the overall image is dark due to deteriorated lighting.

Use an edge pitch measurement to find the number of edges (number of connector pins, etc.) in a measurement object.

In addition to finding the number of edges, this method can be used to find the pitch and width.

Gray Search, Precise Search, and Flexible Search

Use these measurement methods to distinguish between shapes of measurement objects or to find the position (search coordinates) of a measurement object.

When a model is registered, the center position of the model is registered as the search coordinates. (These search coordinates can be changed.)

Search coordinates

(change to a suitable position)

Page 25

Types and Features of Measurement Methods Section 1-2

The part of an input image that is most similar to the model is found, the degree of similarity is expressed with a correlation value, and the search coordinates (X, Y) are found.

Correlation : 95 Search coordinates: (180, 291)

Correlation : 52 Search coordinates: (260, 143)

Labeling

HELP Refer to page 330 for information on density images.

HELP Refer to page 331 for information on models.

HELP Refer to page 330 for information on correlations.

With a precise search, the position is obtained in sub-pixel units. The position accuracy is higher but the processing time is longer than that for a gray search measurement.

Use a flexible search, where multiple models can be registered, for measurement objects with inconsistent shapes that give unstable measurements.

Use a labeling measurement to count how many labels there are in a measurement region and to find the area and center of gravity of a specified label.

HELP Labels are areas of white pixels in a binary image.

HELP Labeling is the process where a different number is given to each extracted

label.

Page 26

Types and Features of Measurement Methods Section 1-2

Images read by the Camera are converted to binary images and the white pixels are extracted as labels. (Any value can be set to the judgement values to determine what area of white pixels becomes a label.)

Measurement region

Labels are extracted and the area and gravity coordinates found.

The extracted labels are sorted by area or center of gravity, and numbers are allocated to each label.

Example: Sort by area in descending order

Relative Search

Rotation Search

012

Use a relative search measurement to find the position of marks, holes, or other features in relation to the reference position.

Register two image patterns as models, one for the reference position and one for the measurement position. The part of an input image that is most similar to the model is found, and the correlation with the model, and the relative position and distance between the 2 output points is obtained.

2-3 Two-camera Unit

Using the Two-camera Unit, two Cameras can be connected to the F160 to enable obtaining two images simultaneously.

Synchronized Images from Different Directions

Example: Checking Boxes from Both Ends

Measurement can be performed for boxes from both ends simultaneously using two Cameras. A Sync Sensor is required.

Prevention Function for Mutual Light Interference

If a Camera with Intelligent Lighting (F160-SLC20/SLC50 or F150-SLC20/ SLC50) or a Camera with a Light Source (F150-SL20A/SL50A) is used, there is a slight difference in the time at which the light sources for the two Cameras come ON (first Camera 0 then Camera 1). Therefore, there is no mutual light interference.

2-4-2-2 Light Control

When using Cameras with Intelligent Lighting, the light level can be adjusted from the F160. Before using Intelligent Lighting, be sure to change the settings in SYS/Camera settings.

SeeAlso Refer to page 293.

TwoCa mera Light levels for Intelligent Lighting can be adjusted for each Camera. The light

level set at Adjust 0/Light Control 0 is for Camera 0 and the light level set at Adjust 1/Light Control 1 is for Camera 1.

CHECK If the shutter speed is faster than 1/2,000 s, changing the light level may not

affect the brightness. Intelligent Lighting emits pulse lighting in synchronization with the shutter speed. The light level is adjusted by changing the pulse width. If the light level is at its maximum setting of 7, the pulse width is approximately 450 µs, which is almost the same as the shutter interval setting of 1/2,000 s. Therefore, setting the shutter speed to a setting faster than 1/2,000 s may have no effect when the light level setting is high. For example, if the shutter speed is set to 1/4,000 s, light level settings will be effective only up to level 4, as shown in the diagram below.

3-1 Area (Variable Box)

The area (variable box) measurement method measures the area and center of gravity while following the measurement region to suit measurement objects with inconsistent sizes and positions.

First, the upper, lower, left, and right edges of the measurement object are located. The area within the edges becomes the measurement region. The location of the measurement object can be determined using the edge detection points so the measurement region can be adapted to suit if the size or position of the measurement object changes.

Once the edges have been located, the image is converted to binary and the area and center of gravity of the measurement region is measured.

Edge Level Set a density change level between 0 and 100 that will indicate the edge. Nor-

mally, the default setting of 50% will be fine. The edge is normally detected as follows:

1. The density distribution of the whole measurement region is calculated.

2. The density difference between the lowest and highest density value becomes 100%.

Page 90

Area (Variable Box) Section 3-1

3. The point where the edge level density change is detected becomes the edge.

Measurement region

100%

Maximum density value

Edge level

Minimum density value

Noise Level Set a noise level between 0 and 255 to assist the determination of edges. The

maximum density and minimum density within the edge detection area is calculated and if the difference between the two values is less than the noise level, then the F160 determines that there is no edge. Normally the default setting of 20 is sufficient. Adjust this to a higher value, however, if noise is causing false edges to be detected.

(Within the edge detection region) Max. density - min. density < noise level → no edge → NG measurement

result Max. density - min. density ≥ noise level → Edge → Used for measurement

Example: When noise level is set to 30

Edge detection region

Max. density 60

60 − 15 > 30

Min. density 15

Edge detected so measurement performed

Edge detection region

Max. density 25

Min. density 10

25 − 10 < 30 Processed as no edge detected. Measurement result NG.

Noise Width Set the noise width between 0 and 255 to evaluate noise.

If the density distribution from the position where the edge was first detected falls to below the edge level within the noise width range, the detected point is judged as noise. Normally the default noise width setting of 0 is sufficient. If noise is causing incorrect detection, make this value higher.

Example

If the density falls below the edge level within the set range, the detected edge is determined to be noise.

Page 91

Area (Variable Box) Section 3-1

Offset Width Set the adjustment width (in pixel units) for the detected edge position. Set a

value between -511 and 511.

The default setting is 0, which means measurement will start from position where the edge is detected.

Offset width

Edge detection point

Left and right edges: Set the offset width on the X axis.

Upper and lower edges: Set the offset width on the Y axis.

Region Region

The edge is not within the region.

When the bottom right coordinates are specified, the region will be set, and the screen in (1.) will return.

CHECK Use the following procedure to fix the measurement region.

• To measure defects in measurement objects with variable widths only, refer to page 75.

• To measure defects in measurement objects with variable heights only, refer to page 75.

• To Measure Defects and Burrs in the Upper Section of Measurement Regions with Variable Widths Only.

Draw the edge detection region so that the measurement region Y coordinates will remain the same for both the upper and lower edges. The upper and lower edges will always have these edge points.

Note Specify X line under Measurement conditions/measurement direc-

tion.
