Sequencer programming for shadow figure extraction applications

Sequencer Programming in Shape and Shadow Applications for VCXG.I Cameras

Software Example: Baumer GAPI v2.9.0

This example explains how to program a sequencer with software triggering for shape and shadow application. Shape and shadow is a technical solution used to extract 3D information from 2D images recorded at the same location but each taken with different lighting. The sequencer is set to take 4 images in rapid succession with a software trigger. The sample uses the VCXG.I cameras' 4 high-power PWM outputs to power 4 flash segments positioned to illuminate the scene from different angles.

If you want to learn more about what to do with the sequence or when to use shape and shadow application, you can refer to the application notes below and the user guide for VCXG.I cameras.

Intended Camera Behavior

The camera is set to trigger mode for shape and shadow purposes. Four images are obtained for each incoming trigger signal.

For each acquired image, the camera outputs activate illumination in one of four sections.
