a first user input designating a first measurement point in the corresponding first image;
a second user input designating a second measurement point in the corresponding first image;
a third user input designating the first measurement point along a selection assist line in the corresponding second image; and
a fourth user input designating the second measurement point along another selection assist line in the corresponding second image;
a point selection module to identify a range of points in the corresponding second image based on the first measurement point designated in the corresponding first image, to generate the selection assist line in the corresponding second image based on the range of points, to identify another range of points in the corresponding second image based on the second measurement point designated in the corresponding first image, and to generate the other selection assist line in the corresponding second image based on the other range of points;
a stereo point module to define a first stereo point based on the first measurement point designated in the corresponding first and second images and to define a second stereo point based on the second measurement point designated in the corresponding first and second images; and
a cross measure module to calculate a distance between the first stereo point and the second stereo point.

Abstract
A stereoscopic measurement system captures stereo images and determines measurement information for user-designated points within stereo images. The system comprises an image capture device for capturing stereo images of an object. A processing system communicates with the capture device to receive stereo images. The processing system displays the stereo images and allows a user to select one or more points within the stereo image. The processing system processes the designated points within the stereo images to determine measurement information for the designated points.
