Stereo Vision
5.1 Synopsis
A stereo vision system views the same scene with two cameras at different van-
tage points to calculate depth information by evaluating the disparity between
the two views for common edge and texture features. NI Vision provides two
example desktop VIs to demonstrate its stereo vision capability, and one of the
demos works on live video streams from two webcams.
In this project you will learn how to set up your stereo vision apparatus,
calibrate the cameras, and view the depth information as a pseudocolor image.
5.2 Objectives
1. Calibrate two webcams for stereo vision
2. View the rectified webcam images
3. View the depth image
4. Compare the depth as measured by the stereo vision system to the true
depth
5.3 Deliverables
1. Screen captures of the desktop VI front panels
2. Lab report or notebook formatted according to instructor’s requirements
5.4 Required Resources
1. NI LabVIEW with NI Vision
