Patent ID: 8731276

Claim:
A motion space presentation device which generates data for presenting a motion space of a movable robot, said motion space presentation device comprising: a work area generation unit configured to generate a three-dimensional region in which the movable robot operates; an image capture unit configured to capture a real image; a position and posture detection unit configured to detect an image capture position which is a position of said image capture unit, and to detect an image capture direction of said image capture unit; and an overlay unit configured to selectively superimpose either a segment approximation model image or a work area image on the real image captured by said image capture unit, according to difficulty in recognizing each image, the segment approximation model image being an image of a segment approximation model of the movable robot, as viewed in the image capture direction from the image capture position, and the work area image being an image of the three-dimensional region, as viewed in the image capture direction from the image capture position.
