Beschreibung
Zusammenfassung:	A signal processing device of a scanning-type distance measurement device includes: a distance calculation unit for, on the basis of a predetermined correlation relationship between measured light and reflection light, calculating, for each predetermined scan angle, the distance from the scanning-type distance measurement device to an object; a to-be-monitored object determination unit for performing a to-be-monitored object determination process, in which, when the distance calculation unit calculates a distance within a to-be-monitored region for N number of scans (N is an integer equal to or greater than 2) consecutively in a specific scan angle direction, it is determined that there is an object to be monitored in the specific scan angle direction; and a signal output unit which, when it is determined by the to-be-monitored object determination unit that there is an object to be monitored, outputs a to-be-monitored object detection signal.
