Abstract

The invention is applicable to the field of laser ranging, and discloses a laser ranging system. The system includes a logic control module, a signal conversion module, an optical module, a laser transmitting module and an echo detection module. The logic control module sends a control signal to the laser transmitting module. The laser transmitting module generates a driving signal according to the control signal, sends the driving signal as a reference signal to the signal conversion module and transmits a pulse laser. The pulse laser is transmitted to a target object through the optical module and generates a laser echo. The laser echo is transmitted to the echo detection module through the optical module. The echo detection module converts the laser echo into an echo electrical signal and sends the echo electrical signal to the signal conversion module. The signal conversion module performs analog-to-digital conversion on the echo electrical signal and the reference signal and sends the signals to the logic control module. The logic control module obtains ranging distance according to the converted reference signal and the converted echo electrical signal. The laser ranging system can eliminate a time-delay error and improve the accuracy of laser ranging.

Description

technical field [0001] The invention belongs to the technical field of laser ranging, in particular to a laser ranging system. Background technique [0002] Laser ranging uses a laser as a light source to emit a pulsed laser. After the pulsed laser is emitted to the target object, a part of the laser is reflected to the ranging point. By measuring the round-trip time of the laser, the distance between the ranging point and the measured target object can be calculated. distance. [0003] The existing laser ranging system uses the original control signal as a reference signal. However, this laser ranging system will bring delay errors, resulting in inaccurate ranging results. Contents of the invention [0004] In view of this, an embodiment of the present invention provides a laser ranging system to solve the problem of inaccurate ranging results due to delay errors in existing laser ranging systems. [0005] An embodiment of the present invention provides a laser ranging ...
