Camera Image Input

Set the conditions for loading images from the camera and for storing images of the measured objects.This processing item must be used when measuring.

Used in the Following Case

Important

●

When using an intelligent camera FZ-SLCx or an auto-focus camera FZ-SZCx, camera image input and camera

image input HDR+ cannot be used together.

●

[Camera Image Input] is preset for Unit 0.Do not set any processing item other than camera image input

(camera image input HDR+) for Unit 0.

●

When switching from a color camera to a monochrome or switching to a camera with a different resolution,

reconfigure the settings in the following units.

●

If a camera is connected other than the one for the previous settings, the camera settings are returned to their

initial settings.

●

It is also possible to set multiple camera image input items to the flow and shoot images at different shutter

speeds. However, in this case, if the images are logged, only the last camera image input is logged.

Settings Flow (Camera Image Input)

Note

●

The displayed items differ depending on the camera type and lighting mode. Perform the following procedure as

necessary in accordance with the use environment.

Camera Settings

Adjust the settings related to camera shutter speed and camera gain. Select the shutter speed appropriate to the speed of the measurement object. Choose a faster shutter speed if the measurement object is moving quickly and the image is blurred. Adjust the camera gain when images cannot be brightened through the shutter speed, lens aperture, or lighting conditions. Usually, the factory default value can be used.

In the Item Tab area, tap [Camera setting].

Input image

In the "Camera settings" area, specify the shutter speed.

The setting methods are to select from the options offered or to set the value directly.

Frame/Field - for Monochrome Cameras Only

There are two methods to transfer one image from a camera to the controller: frame read and field read. Frame read is to read all of the scanned lines of the image. The result is called a frame image. Field read is used to read half of the interlaced scanned lines of the image. The result is called the field image. Here, select the unit to be treated as one image.

In the Item Tab area, tap [Camera setting].

In the "Frame/Field" area, select either "Frame" or "Field".

shorter image input time rather than higher accuracy. Processing becomes faster since each image is scanned skipping one scan line per two consecutive lines, but the measurement precision is decreased because the vertical image resolution is lower.

Number of lines to be read

By narrowing the image range to be loaded, the image scan time can be shortened. Set the range taking the offset of the measurement object into consideration. The part of the image narrowed down by the start line and the end line will be displayed in the Image Display area of the processing item setting window or the Main screen.

Input image

Note

About minimum number of lines

●

The minimum number of lines (minimum number of lines between start and end lines) is 12 lines.

●

For 5 megapixel cameras, the end line is fixed to 1799.

About coordinate values

●

The coordinate values displayed as the measurement results are the values of the display position on the

monitor.

●

The coordinate values do not vary according to the settings for "Number of lines to be read".

In the Item Tab area, tap [Camera setting].

Lighting Control

When a camera with a lighting function is connected, the light volume of the lighting can be adjusted from the controller. Brightness can be adjusted automatically or one of the preset patterns can be selected. A lighting lamp image is displayed as a guide illustration.

Note

●

When one scene contains 2 or more camera image input units, lighting control can be performed only for the

first camera image input unit.

In the item tab area, tap [Screen adjust].

Input image

In the "Lighting control" area, specify the brightness.

The image display contents depend on the connected camera.

Camera Image Input HDR+

This is a processing item for just FZ3-H series high grade controllers. You can acquire a wide dynamic lens image by combining images photographed consecutively at different shutter speeds. With objects that generate halation, images with low-contrast, and environments with fluctuation in the lighting, this processing item is an effective substitute for camera image input.

Used in the Following Case

●

To acquire stable images of objects for which halation occurs easily

●

To measure images with low-contrast stably

Use high-contrast mode.

Model Registration (Flexible Search)

Register the parts to measure as the model. A total of 5 models, 0 through 4, can be registered, with no restriction on the size. If a model has different printing qualities and shapes, more than one models should be registered. The position at the time of registration is also registered in the model information.Place the measurement object in the correct position when registering a model.

Adjusting the Edge Level

In an ECM search, processing is executed on the edge extraction image. Change this item as necessary when the edge is not extracted or is extracted along with noise.

Measurement

Important

●

In model registration, extract as much of the edge as possible, then delete noise etc. in the mask registration to register the entire edge of the model. On the other hand, when measuring, even if the edge has skips, an image with the noise suppressed makes it possible to search the model stably. To set separate edge extraction conditions for model registration and for measuring, after registering the model, change the edge extraction conditions.

Shape Search+

This is a processing item for just FZ3-H series high grade controllers. This processing item searches the input image for parts having a high degree of similarity to the target mark (model) and detects its correlation value (similarity) and position at high speed.

Measurement

In a normal search, image pattern models are used that look at the color and light/dark information, but in a shape search, models are used that look at the profile information.Therefore, this processing assures a reliable search even for low-contrast or noisy images. It is also possible to search reliably for marks of difference size. This is used to search at higher speed than for an ECM search. This processing item is for monochrome only.When using a color camera, put in the color gray filter. If a color image is input, it is NG (incompatible image).

Used in the Following Case

●

To measure the location of a mark

Important

●

When FZ3-H series dedicated processing items are used, processing is carried out that reduces the processing time from the second time on. Therefore, when measuring the same image, the processing for the first time after the controller is started up may be longer than the processing time from the second time on.
