PROBLEM TO BE SOLVED: To improve accuracy in the inspection of whether an arrangement reference axis coincides with an installation reference axis regardless of azimuth resolution in a laser radar device.SOLUTION: In deviation angle derivation processing, the highest intensity range &thetas;, an adjacent angle range &thetas;, the second intensity range &thetas;, and an adjacent angle range &thetas;in measurement data, which are results of receiving reflected light by emitting a laser beam to a target plate are specified, and also reflected light reception intensities at the angle ranges &thetas; are specified (S210 to S240). Then, the specified light reception angle range &thetas; and the reflected light reception intensity at the light reception angle range &thetas; are checked up with model angle data (S250). In S250, the axis angle highest in the degree of coincidence as a result of the check up is specified. If the specified axis angle is not 0, it is informed as the indication of axis deviation. |
