The settings of the stereo parameters greatly depend on what you are trying to achieve. The best way to determine the stereo parameters that fit your needs is by using DigiclopsDemoII or TriclopsDemos and changing the parameters until they meet your needs.
We suggest that you have the camera pointed at a typical scene that you will be using the system in. Make sure that the distance to the objects that the camera is pointing at is similar to the distance that will be used during operation of the system.
We suggest that you have the disparity image and point cloud windows open. You will want to watch the affect that the parameter changes have on, speed of execution (you can read this number out in the bottom right corner of the window), density of the points, accuracy/resolution of the data, and amount of noise in the 3D data.
- If the closer objects are found to be invalid try increasing the maximum disparity setting.
- If most of the image is too dark try reducing the maximum disparity setting.
- If the scene is textured, but the depth image is sparse with depth measurements try increasing the stereo mask and the edge mask.
The stereo parameters and their effects are described in the user manual.
