Abstract

The invention provides a laser radar data point processing method and device, which relate to the technical field of laser radars. The method comprises the following steps of obtaining a first reference point set and a second reference point set of to-be-processed contour imaging points, wherein the first reference point set and the second reference point set are a plurality of contour imaging points located on the two sides of a to-be-processed contour imaging point respectively, and the number of the first reference point set is equal to that of the second reference point set, according to the first reference point set and the second reference point set, smoothing the to-be-processed contour imaging point, acquiring the smoothed horizontal and vertical coordinate values of the to-be-processed contour imaging point. More accurate data points are obtained, and therefore the purposes of high-precision distance measurement and high-precision imaging are achieved.

Description

technical field [0001] The invention relates to the technical field of laser radar, in particular to a method and device for processing laser radar data points. Background technique [0002] LiDAR (LightLaser Detection and Ranging, LiDAR), short for laser detection and ranging system, is a radar that uses lasers as radiation sources. Lidar is the product of the combination of laser technology and radar technology. It is composed of transmitter, antenna, receiver, tracking frame and information processing. Transmitters are various forms of lasers, such as carbon dioxide lasers, neodymium-doped yttrium aluminum garnet lasers, semiconductor lasers, and wavelength-tunable solid-state lasers; the antenna is an optical telescope; the receiver uses various forms of photodetectors, such as photoelectric Multiplier tubes, semiconductor photodiodes, avalanche photodiodes, infrared and visible multiple detection devices, etc. LiDAR adopts two working modes of pulse or continuous wav...
