Abstract
A method for gathering information about a work environment comprising using two laser rangefinders to obtain distances to two obstacles. A camera captures an image of the area and an image processor extracts the color depth at the two points of the laser rangefinders. The image processor then extracts the color depth of the line connecting the two points of the laser rangefinders. If the color depth of the two points of the laser rangefinders and the line connecting them is within a predetermined range, the system identifies the area as a substantially flat surface. When a substantially flat surface is found, the system can calculate the length and angle of the line connecting the two points of the laser rangefinders.
