A Method for Constructing a Multi-Sensor Measurement Simulation Platform for Three-Dimensional Reconstruction of Spatial Targets

Research related to current spatial targets commonly faces difficulties in obtaining real spatial data and high costs. A simulation platform for three-dimensional reconstruction of spatial targets based on Blender and Blensor was built to address this issue. A multi-angle acquisition process was designed to control the camera and LiDAR to surround the target with material information at set distances and angles for data collection. Additionally, light sources and a black background were added to simulate sunlight and the space environment. Visualized experimental results demonstrate high quality images and point clouds generated by the platform simulation. Quantitative experimental results further indicate that rendered images accurately depict the specular reflection characteristics present on the surface of spatial targets, showing it an efficient simulation of actual data collection.
