Reference image generation based on three-dimensional realistic scene modeling for contour-based infrared ATR algorithm

A reference image creating approach is proposed in this paper for contour-based infrared ATR algorithm. The approach based on three-dimensional realistic scene modeling consists of five parts: three-dimensional scene model construction, view plane simulation, coordinates transformation and perspective projection, visible-surface identification and three-dimensional rendering algorithm, contour extraction algorithm. By using this approach, a distinctively reference image is rapidly generated at multiple objective views and different scales. Numerical experiments are chosen to test proposed method from velocity performance. The experimental results indicate that the performance of the proposed technique is better than that of other methods.
