基于鱼眼镜头的全方位视觉系统的设计及实现

Based on the Fish-eye Lens of the Omnidirectional Vision System Design and Implementation

在对基于全方位视觉的移动机器人机动目标识别跟踪进行研究的基础上,建立了基于鱼眼镜头的全方位视觉图像的畸变矫正系统.该系统采用基于立方体投影模型来矫正畸变的鱼眼图像,并用基于立方体投影的鱼眼镜头图像畸变校正系统对鱼眼图像进行了畸变校正.实验结果表明采用以上方法能够有效的克服原始的鱼眼图像存在的几何变形,校正后的鱼眼图像符合人的直观感觉,真实感较强.

Based on the studing of omnidirectional vision-based mobile robot to track maneuvering target recognition,this paper established the all-around vision image which based on the fisheye lenses aberrations correction system.The system is based on the cube projection model to correct the distortion of the fish-eye image,and use the cube projection based on the fish-eye lens image distortion correction system for fish-eye image of the distortion correction.Practice has proved that：the above method can effectively overcome the existence of the original fish-eye image geometric distortion,correction after the fish-eye image in line with people＇s intuitive sense of realism stronger.
