Stereoscopic measurement system and method

A system comprising modules executable with at least one processor for obtaining measurements from a stereo image of an object, the stereo image comprising first and second images of the object, the system comprising:

• a user interface (UI) module to generate the first image and the second image for display and to receive a first user input designating a first measurement point in the first image and a second user input designating a second measurement point in the first image;
• a point selection module to define a projection vector in the second image based on the first measurement point, to generate a selection assist line in the second image based on the projection vector, to identify another projection vector in the second image based on the second measurement point, to generate another selection assist line in the second image based on the other projection vector, to determine first pixel values adjacent to the first measurement point, to compare the determined first pixel values with other pixel values along the selection assist line to dynamically identify a corresponding first measurement point in the second image with adjacent other pixel values that match the determined first pixel values, to determine second pixel values adjacent to the second measurement point designated in the first image, and to compare the determined second pixel values with second other pixel values along the other selection assist line to dynamically identify a corresponding second measurement point in the second image with adjacent other pixel values that match the determined second pixel values;
• a stereo point module to define a first stereo point that corresponds to the first measurement point designated in the first image and identified in the second image and to define a second stereo point that corresponds to the second measurement point designated in the first and identified in the second image;
• and
• a cross measure module to calculate a distance between the first stereo point and the second stereo point, wherein the user interface is further configured to display the distance between the first stereo point and the second stereo point.

A method for obtaining measurements from a stereo image of an object using at least one processor, the stereo image comprising first and second images of the object, the method comprising:

• defining a first stereo point that corresponds to the first measurement point designated in the first and second images and defining a second stereo point that corresponds to the second measurement point designated in the first and second images;
• and
• calculating a distance between the first stereo point and the second stereo point.
