Title: Optical range-finding apparatus
Inventor: FUKADA SHINPEI
IPC: G01S17/10
Filed: 2011-04-14
Abstract: PROBLEM TO BE SOLVED: To provide an optical range-finding apparatus which is capable of measuring a distance to a target even if noise is superimposed on a reception signal.SOLUTION: An optical range-finding apparatus comprises signal reception means, amplitude comparison means, distance computation means, specific frequency component removal means and threshold value change means. The signal reception means iteratively transmits a laser pulse to an approaching target and receives reflection light from the target. The amplitude comparison means compares a maximum amplitude value of received signals with a predetermined threshold value. The distance computation means computes a distance, to the target, from the time point of transmitting a laser pulse in the case where the amplitude comparison means determines that the maximum amplitude value before laser pulse transmission is smaller than the threshold value, and from the time point of receiving a signal received by the signal reception means. When it is determined the maximum amplitude value is larger, in the specific frequency component removal means, frequency characteristics of the reception signal are detected and when a specific frequency component greater than others is detected in the detected frequency characteristics, the output is inputted to reception signal detection means after the specific frequency component is removed. When no greater specific frequency component is detected, without computing the distance to the target by means of the distance computation means, the threshold value change means performs a change into maximum amplitude value larger than the threshold value.
