description The invention relates to a three-dimensional imaging system point cloud hole completion system and method, and belongs to the technical field of point cloud hole completion. The method comprises the following steps: firstly, acquiring point cloud data, color images and intensity data of the same field of view under different integration times, and identifying and marking cavity areas and boundaries in the point cloud data; secondly, acquiring spatial distribution of depth data by using color image features, and accurately aligning visual features in the color image and corresponding spatial positions of holes in the point cloud data; and finally, acquiring intensity data under different integral times, complementing the cavity region by adopting a wide dynamic range fusion mode, and further improving the data quality of the cavity region by combining a radial basis function interpolation algorithm. According to the technical scheme provided by the invention, the cavity area in the point cloud data can be accu
