Laser radar distance measuring apparatus and laser radar distance measuring method

Abstract

Embodiments of the present application provide a laser radar ranging device and a laser radar ranging method, wherein the device comprises: a main control module that outputs a first pulse width adjustment signal and a second pulse width adjustment signal at intervals within a ranging period; a pulse width modulation module that generates a first pulse width drive signal according to the first pulse width adjustment signal, and generates a second pulse width drive signal according to the second pulse width adjustment signal; a laser emission module that emits a first pulse signal under the drive of the first pulse width drive signal, and emits a second pulse signal under the drive of the second pulse width drive signal; the pulse width of the first pulse signal is greater than the pulse width of the second pulse signal; and a return signal processing module that converts a first return signal of the first pulse signal reflected by a measured object into a first electric signal, and converts a second return signal of the second pulse signal reflected by the measured object into a second electric signal. Through the present application, the technical problem that the ranging capability cannot be guaranteed while reducing the blind area in the related art is solved.
