Range Images
Note: Only DS1000 series sensors acquire range images capable of being analyzed by Cognex 3D vision tools.
Some of the content in this section may not apply to the profile images acquired by the DL1000 series sensors.
A range image is a 16-bit greyscale image containing height profile information in real-world coordinates. A range image
can be viewed on a typical 2D display or the Cognex 3D Viewer application:

Your Cognex software generates the range image from a series of acquired intensity images.
Intensity Images
To create an intensity image, the sensor first projects a triangular laser plane onto the object under inspection, creating a
laser stripe whose shape is determined by the height of the object features.
