Patent attributes
An angled axis machine vision system having two cameras angled with respect to roil axis. Provides advantages of horizontal alignment between two cameras and eliminates problem of utilizing horizontal/vertical lines in the environment for distance calculations when lines arc parallel or close to parallel to axis between camera centers. With camera centers angled about roll axis, horizontal/vertical lines in environment appear angled with respect to horizon, enabling accurate distance calculations. With the cameras angled about roll, lines in the environment may line up parallel to the axis between camera centers, but these instances are rare in real world environments. May be rotatably mounted in the roll axis wherein two sets of pictures from each of the cameras may either he utilized: the two sets compared for the number of parallel lines parallel to axis between camera centers and the set of pictures with least parallel lines used for distance calculations.
