The invention discloses a laser ranging controller and laser ranging equipment. The laser ranging controller comprises a driving module and a control module used for sending a pulse control signal to the driving module. The driving module comprises: a clock signal generating circuit for outputting a clock signal; the charge pump circuit is used for charging by using the clock signal so as to boost the low-level voltage to a high-level voltage required by a laser transmitter; the pulse signal generation circuit is used for outputting a pulse signal with a corresponding pulse width according to the pulse control signal; the driving circuit is used for forming driving voltage of the laser transmitter according to the pulse signal, and the output end of the driving circuit is used for being connected with the cathode of the laser transmitter; and the electrostatic discharge circuit is used for forming an electrostatic discharge loop. According to the invention, the driving function and the power supply function of the laser transmitter can be integrated to the laser ranging controller in a reliable manner, and the hardware cost of laser ranging is reduced.
Description
technical field [0001] The invention relates to the technical field of laser ranging, in particular to a laser ranging controller and a laser ranging device. Background technique [0002] In recent years, Direct Time of Flight (dTOF) technology has been more and more widely used in the fields of unmanned driving, lidar and machine vision, and is considered to be one of the most accurate, reliable and effective ranging methods in the future. one. The principle of dTOF technology is: the laser pulse is sent from the laser transmitter, reflected by the object and then reaches the laser receiver, and the flight time of the laser pulse round trip is recorded and used for accurate ranging. [0003] At present, the commonly used laser ranging controller in dTOF technology generally includes a control module for sending a pulse control signal to the driving module of the laser transmitter. The laser transmitter outputs a driving signal, and the laser transmitter supplies power by ...
