Abstract: A lidar, and an anti-interference method therefor, may modulate a transmitting time of the lidar by injecting random time jitter at a time interval in a sequence of the transmitting time, and cause the lidar to transmit a laser pulse according to a modulated transmitting time. When an echo received by the lidar includes an expected echo of the local lidar and an unexpected echo from other lidars, because the transmitting time and the expected receiving time of the echo are correlated, injecting random time jitter in the transmitting time of the lidar may disrupt the correlation between the transmitting time of the local lidar and the transmitting time of other lidars. Thus, when a plurality of lasers are used together in one scenario and cause crosstalk, the anti-interference method for the lidar above can be used to fight against crosstalk to some extent.

Abstract: This application provides a point cloud data sorting circuit, method. The point cloud data sorting circuit includes a sorting module, which contains a row caching unit and a row sorting unit. The row caching unit is configured to obtain and cache original point cloud data to be sorted. The original point cloud data is obtained by scanning the field of view with the LiDAR. Between two rows of original point cloud data obtained in one second scanning period, there are N rows of other original point cloud data obtained in another second scanning period. The row sorting unit is configured to perform coordinate transformation on the original point cloud data to obtain target point cloud data sorted according to pitch angles. This allows the sorting of original point cloud data to be achieved using independent hardware, improving the sorting speed of the original point cloud data.
