目的:针对平面定机拍摄中存在的边缘镜头畸变现象,提出一种快速、易操作的修正方法。研究对象与方法:对固定标志物和实际比赛视频分别进行了实验验证和实例检验。结果:三种被测镜头在图像边缘处的畸变误差百分比为2.75%—4%;对比赛现场拍摄的运动图像进行处理后,解析点在图像边缘运动速度前后差值百分比分别为5.9%和8.18%。结论:利用Lensdoc插件可以快速有效地对镜头畸变进行修正。
Aim: This paper puts forward a rapid and operatable method of correction aimed at the phenomenon of edge camera distortion in plane fixed filming.Study object and method: It makes experimental verification and example test on the video of fixed markers and the actual match.Result: Experiments shows that the edge distortion errors of the three types of lens are between 2.75%-4%.The percentage of difference of the reparse point before and after movement speed is 5.9% and 8.18%.Conclusion: The lensdoc plug-in software can solve the lens distortion quicklyand effectively.
