Abstract

Due to cost and realistic feasibility limitations, the current research on laser active imaging guidance technology is based on simulation models. In this paper, the complete process of laser emission, target reflection and detector reception are modeled and simulated, and finally the range image is obtained. Due to the large number of actual scene bins, bins are screened first to increase the intersection speed between the beam and the target. Also, a fast algorithm for ray intersection in real scenes is proposed, which improves the operation speed to over 70 times. Based on the fast algorithm, this paper divides the whole imaging process simulation into three steps: beam vector solution, beam target intersection and projection point related information acquisition.
