This invention discloses an efficient 2D dynamic soft shadow rendering method and system based on symbolic distance fields, belonging to the field of computer graphics and image processing technology. It includes extracting displacement vectors to determine active occlusions and generating bounding boxes to be updated; downsampling and reconstructing within the bounding boxes and concatenating with an external buffer to generate a low-resolution symbolic distance field; calculating a local original resolution symbolic distance field within the same region; calculating and normalizing the difference matrices of the two types of distance fields to generate a fusion weight matrix; and using the weight matrix to weightedly superimpose the two types of distance fields, performing ray propagation to output shadow textures. This invention uses bounding boxes established based on inter-frame displacement vectors to lock dynamic regions and constructs pixel-by-pixel fusion weights through multi-level resolution distance difference matrices to achieve smooth superposition of heterogeneous field data. This significantly reduces scene reconstruction overhead while eliminating visual seams caused by incremental updates, outputting high-quality and spatiotemporally continuous 2D soft shadow effects.

This invention relates to a method for generating massive multi-band images using machine learning for space-based target detection. The method calculates the optical properties of a 3D target, fuses the target's optical image into a 2D background, and can quickly simulate multi-band optical images. Addressing the problem of insufficient training samples in multi-band machine learning target detection algorithms, this paper proposes a fast calculation method for target-background fusion. This method includes simulating the background's optical image in multiple bands, adding a target optical property image with a shadow effect to the background using a 3D model optical property calculation method, and simulating different time conditions through meteorological parameter settings and temperature calculations. Experiments show that this method can quickly simulate multi-band optical images fused with 3D targets while maintaining the accuracy of optical property calculation.
