LumaSense Technologies Pearl OEM User Manual

Pearl Quick Start Guide

Introduction

The Pearl Camera is
a flexible platform to
support a variety of
infrared imaging appli­cations. The standard
output is NTSC video.
The Pearl Camera prod­uct is suited for applica­tions requiring high quality infrared imaging without the
added cost of precision radiometry.

The Pearl Control Software is designed to allow users to
control the Pearl OEM camera or camera core. Users can
adjust video settings, capture images, and use the software
to assist in calibration. Pearl Control software is provided
on a disc in the case and is shipped with the camera.

Pearl OEM Camera

The Pearl OEM Camera is a fully enclosed thermal imag­ing camera designed to operate with LumaSense
IR detectors with external connectors. The product is also
offered in an optimized midwave configuration for high
temperature and see-through flame applications.

Pearl Camera Core

The Pearl Camera Core includes a three-board electronics
stack with detector mounting assembly, but it does not
have an enclosure. The design is portable among pro­grammable hardware manufacturers and can be inte­grated into new or existing designs.

connected camera, click Use Settings. If settings are
unknown, click Scan and the program will search for
the camera.

Configuring Video Settings

The following settings and screenshot (top right) displays
some general settings for the video that should display a
high quality image.

Display Adjustment Mode: All Automatic

The Display Adjustment Mode allows you to configure
Brightness and Contrast automatically or manually.

Automatic Mode Settings: Minimum Bias

Note: Automation Mode Settings are only applicable

when the camera controls brightness and/or contrast.

Pearl Control Software - recommended settings

Color Map: Grayscale

The Pearl Control Software
includes four preset color maps
to choose from: grayscale,
saturn, hot iron, and gray lava.

Polarity: White Hot

The video polarity determines which values are used for
high and low temperatures. The Pearl Control Software
offers two options: white hot and black hot.

Frame Average: None

Frame averaging can help smooth out or remove motion
in the image. The values determine how many frames are
averaged together before displaying an image. Selecting
None turns off frame averaging.

Flipping: Both Unchecked

Flipping will flip the image along both the X and the Y
axis. This is useful if a lens has flipped the image or the
camera is mounted upside-down.

Regional AGC: Unselected

When the Regional AGC box is unchecked, the Automatic
Gain Control (AGC) uses the whole image to automati­cally change the brightness and the contrast. When the
Regional AGC box is checked, the AGC uses only the areas
in the image that are black. The white areas are ignored.

Capture Image

Single frames can be captured from the camera and
downloaded to the Pearl Control Software. In addition
to the live image, other types of images can be down­loaded for diagnostic checks.

Note: The Capture tab is not available on all versions of
the Pearl Camera. Only versions 5.0.8 and newer support
this feature. This tab is disabled for older versions.

To capture an image:

1. Mark the desired Data Selection

2. Click Take Snapshot. The camera will take a snapshot
of the live image.

3. Click Download Data to retrieve the image from the
camera. This takes roughly 15 seconds to complete.

Note: You can change the Color Map for the image by
using the drop down menu.

Auto-Cal: Enabled, with a suggested time of
300 seconds (5 minutes)

Automatic calibration (Auto-Cal) is used to keep the
camera image quality looking good.

Note: This function is set to the suggested time. It can
only be changed when Advanced is selected and the
password is entered. See section on “Access to Calibra­tion Tab.”

Save Data

The Pearl Control Software allows you to save data to
your computer. The filename will be the camera number
followed by a unique timestamp. The file type is a PRN
file (used in MathCad), but can be changed to a plain text
file. The data is in a simple text format. Pixel values are
written with spaces in between each pixel, and a new line
is used for each row.

To save data to the default location:

1. After capturing an image, click Save.

2. The currently displayed image will save to the
defaulted specified location.

To save data to a new location:

1. Click Browse and navigate to the file location you
would like to save the image to.

2. Click OK.

3. Click Save to save the image to the new location.

Access the Calibrate Tab

A password is required to unlock and access the Calibrate
Tab and Reset Camera feature.

To access the Calibrate Tab:

1. Click Help on the Menu Bar.

3. Type in the password: engineer

4. Click OK or press enter.

5. The Calibrate Tab will appear below the Capture Tab
in the Action Bar.

Resetting the Camera

Unlocking the Calibrate tab will also unlock the “Reset
Camera” option in the Help menu. Reset Camera can be
used to reset the various features in the camera. You
may want to reset the camera if it is changed to an unus­able state.
