i've been learning about stereoscopic 3d lately and there is one thing that is not so clear to me. What is the difference between parallax and disparity.
I have the feeling that both terms are being used interchangeably.
Example definitions:
Binocular disparity refers to the difference in image location of an object seen by the left and right eyes, resulting from the eyes’ horizontal separation.
The distance between left and right corresponding image points (sometimes also called “homologous” or “conjugate” points) is parallax, and may be measured in inches or millimeters.
"Disparity" (usually in "disparity map") is a computed estimate of the parallax as observed in an image pair.
