PROBLEM TO BE SOLVED: To provide a laser radar device that can measure the installed position and the installed angle of a scanner in real time without requiring to install a target for calibration outside the laser radar device.SOLUTION: A window 5 in which a plurality of markers 6 reflecting laser beams is arrayed is arranged in a position through which laser beams radiated from a scanner 3 pass. A positional angle identifying part 12 acquires from a distance intensity image generated by a distance intensity image generating part 11 the distance values Land positional coordinates (x, y) of the plurality of markers 6, and identifies the installed position δand the installed angle &thetas;of the scanner 3 on the basis of the acquired distance values Land positional coordinates (x, y).SELECTED DRAWING: Figure 1 |
