基于SOPC的三维坐标转换

在多摄像机目标检测跟踪系统中,所获得的图像目标都在各自坐标系下,为便于统一身份管理,需将目标统一到同一视场下。本文采用基于MicroBlaze微处理器软核的SOPC解决方案,根据三维坐标转换原理,结合CORDIC算法,实现三维坐标在不同坐标系间的转换。随后给出了该方案的设计过程和仿真结果。仿真结果表明,它的精度高,误差小。与传统方案相比,具有集成度高、功耗低、可靠性好等优点。

3D Coordinate Transformation Based on SOPC

Targets obtained by target detection in a multi-camera tracking system are in their respective coordinates. To facilitate unified identity management, targets need to be transformed to the same coordinate. In this paper, we employ the solution of SOPC system design, which is based on the MicroBlaze embedded soft core processor, according to the principle of coordinate transformation and CORDIC algorithm, 3D coordinate transformation is realized. Then the design process and simulation results are given. Simulation results show that the resolution of this method is high, and error is small. Compared with traditional solution, it features high integration, low power consumption and good reliability.
