The invention relates to the technical field of laser ranging, and discloses a laser ranging anti-interference method and device, laser ranging equipment and a readable storage medium. Based on the laser ranging anti-interference method, after a plurality of transmitting and receiving durations corresponding to a plurality of echo pulse signals one by one are obtained through calculation, by utilizing the characteristic that the transmitting and receiving durations corresponding to the interference signals are obviously different from other transmitting and receiving durations corresponding to the correct echo pulse signals, the transmitting and receiving durations corresponding to the interference signals are eliminated from the multiple transmitting and receiving durations through a preset range, and the transmitting and receiving durations corresponding to the correct echo pulse signals are reserved. Therefore, the interference signal can be effectively filtered through the elimination result of the transmitting and receiving time length, the correct echo pulse signal is obtained, the anti-interference purpose is achieved, the calculated amount and the related operation complexity degree can be greatly reduced on the basis of guaranteeing the anti-interference accuracy, the hardware cost of the laser ranging equipment is reduced, and convenient practical application and popularization are facilitated.
Description
technical field [0001] The invention belongs to the technical field of laser ranging, and in particular relates to a laser ranging anti-interference method, a device, a laser ranging device and a readable storage medium. Background technique [0002] Lidar is a radar system that emits laser beams to detect characteristic quantities such as the position and / or speed of the target. Among them, Lidar ranging plays an indispensable role in the perception link of the field of intelligent sports because of its excellent characteristics. . However, as the use of lidar becomes more and more widespread, for any lidar in use, within its effective range, it will inevitably face the presence of interference lidar that emits laser pulse signals of the same wavelength nearby. The similar or even identical laser pulse signals sent out will make it difficult to distinguish after being received by the laser radar, resulting in crosstalk and misjudgment. [0003] The existing technology to ...
