    In the layout process of LiDAR and camera, the original layout constraints are not precise or comprehensive enough, resulting in lower coverage after layout, which affects the reliability of measurement results. Therefore, a laser radar and camera layout optimization method based on hot spot areas is proposed. Complete the motion trajectory data of the target area, preprocess it, obtain scene hotspot data, and determine the scene hotspot area. Based on the obtained scene hotspot data, laser radar layout constraints are constructed through three parts: distance, angle, and collision. Determine the motion speed of the LiDAR, use a grid to partition the hot spot areas of the scene, and apply constraint conditions to solve for the optimal layout position. Constructing an experimental section, the experimental results show that this method achieves layout optimization and can further improve the coverage of LiDAR and camera layout, ensuring the reliability of LiDAR and camera measurement results.
