This application provides a parameter configuration method, device, and non-transitory computer-readable storage medium. In this method, the receiving units in the LiDAR receiving array are grouped according to a preset rule. Then, based on the detection requirements, the measurement range corresponding to each group of receiving units is set. Based on the measurement range of each group of receiving units, the storage space for each group of receiving units is set. The storage space is used to store the measurement data of each group of receiving units. Thus, the method reduces the acquisition of measurement data by some receiving units in unnecessary measurement ranges, decreases the volume of measurement data, and saves storage space.

Parameter configuration method, device, and computer-readable storage medium

The present disclosure provides a LiDAR device and its ranging adjustment method. The ranging adjustment method involves first calibrating the echo intensities at different pixel positions in receiving units of the LiDAR device and then determining the corresponding correction coefficients. Based on these correction coefficients, the method corrects the intensity data output by the pixels at different positions, ensuring consistency in the intensity data output by the corresponding pixels of the same receiving unit.

Lidar device and ranging adjustment method

The present application discloses a LiDAR controlling method and device, an electronic apparatus, and a storage medium. The method includes: in a measurement period, determining an emitting group to be started in the measurement period from a laser emitting array, where the emitting group includes at least two emitting units, and physical positions of the at least two emitting units meet a condition of no optical crosstalk; controlling the at least two emitting units to emit laser beams asynchronously based on a preset rule; controlling a receiving unit group of the laser receiving array corresponding to the emitting group to receive laser echoes, where the laser echoes refer to echoes formed after the laser beams are reflected by a target object; and when at least two emitting groups are determined in the measurement period, controlling the emitting groups to emit the laser beams asynchronously based on the preset rule.

LiDAR controlling method and device, electronic apparatus and storage medium

The present application is applicable to the technical field of a LiDAR, and provides a LiDAR control method, a terminal apparatus, and a computer-readable storage medium. The LiDAR control method includes the following steps: acquiring first echo data; when an oversaturated region is determined to exist according to the first echo data, controlling LiDAR to measure a scanning region according to a second preset scanning mode to obtain second echo data; performing data fusion processing based on the first echo data and the second echo data to obtain target data. The LiDAR is controlled to measure according to the first preset scanning mode and a second preset scanning mode, and then fusion is performed based on the measured first echo data and second echo data, thereby effectively eliminating a problem of signal crosstalk caused by too high reflection energy of an object with high reflectivity, and effectively improving measurement accuracy.

Lidar control method, terminal apparatus, and computer-readable storage medium

This application is applicable to the field of radar technologies, and provides a radar data processing method, a terminal device, and a computer-readable storage medium. The method includes: obtaining radar data collected by a receiving area array; if the radar data is saturated, performing data fusion processing based on a floodlight distance value to obtain a fusion result; and determining a distance of a target object based on the fusion result. The method can accurately obtain an actual distance of the target object, effectively reduce a measurement error, improve calculation accuracy, and resolve an existing problem of a large deviation of a measurement result when an actual echo waveform cannot be effectively restored because a signal received by the radar is over-saturated when a laser is directly irradiated on a target object with high reflectivity.
