    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.
