PROBLEM TO BE SOLVED: To enhance the detecting accuracy of laser radar devices.SOLUTION: If it is determined at step S152 that the intensity of the reflected light in every direction is at or above a prescribed threshold, at step S153 that the differences in detection distance among different directions are within a prescribed range, and at step S156 the difference in normalization received light value between the latest and immediate preceding occasions is within a prescribed range, the update counter is incremented at step S158. If at step S159 it is determined that the update counter has surpassed a threshold, at step S160 correction coefficients for correcting the received light values of different light receiving elements are updated on the basis of the normalization received light value of each light receiving element. This device is applicable to, for instance, laser radar devices for on-vehicle use.SELECTED DRAWING: Figure 11 |
