中文摘要：
针对常规全向反射镜面设计方法对球形目标会产生较大的形变和由于形变带来的区域间颜色互相影响的问题,分析得到了控制球形目标成像所需满足的四个基本要求,进而提出了一种控制球形目标成像的全向反射镜面设计方法。该方法利用具有凸型反射镜面基本性质的双曲线面型作为反射镜面的基本面型;以在单视点约束条件下所确定的目标特征点与成像特征点间的关系为依据,采用遗传算法得到反射镜面的面型参数。将该设计方法得到的反射镜面与水平无畸变反射镜面、锥型反射镜面的效果进行了比较,仿真与实际效果说明了设计方法的有效性。
英文摘要：
Aiming at the problem that general design methods of reflection mirror almost all bring image distortion of spherical object and color mixing of different components,this paper analyzes and obtains four basic requirements of controlling spherical object imaging,then presents a new omni-directional reflection mirror design method for controlling spherical object imaging.This method uses hyperbola mirror with basic property of convex reflection mirror as the base mirror type,takes the relation between object and imaging characteristic points obtained under the restriction of single-viewpoint as the basis,and obtains the parameters of the reflection mirror using genetic algorithm.The proposed method was used to make mirrors,which were compared with cone mirror and undistorted horizontal scene mirror.Simulation and real imaging results show the validity of the proposed method.
