Nitzan, D. (1972). Stereopsis error analysis. Stanford Research Institute Menlo Park United States.
The error due to image quantization in stereoscopically evaluated range is analyzed, using a simple camera model and assuming that the image planes of the two cameras are coplanar. The “best” position and the uncertainty space for a point in space are calculated on the basis of the quantized image co-ordinates of that point in the two cameras.
