Laser Measuring Method And Laser Measuring Instrument

A laser measuring instrument comprising:

• a light emitter for pulse-emitting a distance measuring light, a driver for making said light emitter emit, a scanning unit for scanning while irradiating said distance measuring light, a light receiving signal processing module for receiving a reflected distance measuring light from a measuring point, detecting a reciprocating time per pulsed light of said distance measuring light with respect to said measuring point, and performing a distance measurement based on the reciprocating time, and a timing generating circuit for issuing a timing signal for controlling a light emission timing of said light emitter and a timing signal for controlling a detection timing or said reflected distance measuring light, wherein said timing generating circuit is configured to input a timing signal for pulse-emitting said light emitter in a short cycle and a timing signal for pausing a light emission to said driver, said driver is configured to make said light emitter pulse-emit according to the timing signals from said timing generating circuit, a light emission time interval in said short cycle is set such that said measuring point is multiply irradiated with the pulsed light by two or more times within a time when the pulsed light passes said measuring point, and said light receiving signal processing module is configured to integrate light receiving signals acquired by multiply irradiating the pulsed light by two or more times and to carry out the distance measurement based on the integrated light receiving signals.
