A RAY TRACING BASED MODEL FOR 3D LADAR SYSTEMS

Tomas Chevalier

2011

Abstract

This paper describes an approach to simulate long range laser based 3D imaging sensor systems. The model is based on a ray tracing principle where a large amount of rays are sent from a sensor towards the scene. The scene, the target surface, and the atmosphere affect the rays and the final light energy distribution is acquired by a receiver, where sensor data is generated. The approach includes advanced descriptions of the materials in the scene, and modeling of several effects in the atmosphere and the receiver electronics. A turbulence model is included to achieve realistic long range simulations. Examples of simulations and corresponding real world data collection are shown. Model validations are presented.
