1. An apparatus comprising:
a controller configurable to:
generate a pattern of points;
obtain a first image of a first reflection of a projection of the pattern of points from a first camera;
generate a first point cloud having a first coordinate system responsive to the first image;
obtain a second image of a second reflection of the projection of the pattern of points from a second camera;
generate a second point cloud having a second coordinate system responsive to the second image;
generate a rigid body transform to convert coordinates of the second coordinate system to coordinates of the first coordinate system;
apply the rigid body transform to the second point cloud to generate a transformed point cloud; and
generate a corrected point cloud responsive to the transformed point cloud.
