Abstract: 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.

Abstract: A radar ranging method, device, electronic device, and computer-readable storage medium are provided. The radar ranging method includes: obtaining a plurality of measurement data sets by sampling at least one echo signal based on a plurality of thresholds in a measurement period, wherein the echo signal is sampled based on one threshold to obtain one measurement data set, and each measurement data set includes at least one measurement data; determining M backup data and N auxiliary data in the plurality of measurement data sets, and obtaining a total composite degree of each backup data; determining target data from the M backup data, based on the total composite degree; and determining a measurement distance based on the target data. The radar ranging method enhances the dynamic range of a LiDAR system, improves the measurement accuracy of the LiDAR and reduces the short-distance detection blind zone of the LiDAR.

Abstract: 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.
