畸变差 meaning in Chinese
photogrammetric distortion
Examples
- Asymmetric lens distortion
透镜不均匀畸变差 - The measurement and alteration of ordinary digital camera . it includes the correction of lens distortion of digital cameras , the computing of camera interior orientation parameters and pictures " exterior orientation parameters , and the evaluation of it ' s capability ; 2
其中包括普通数码影像畸变差的改正、数码相机内方位元素的检定、数码近景摄影机的研制及外方位元素改正值的确定、普通数码相机量测化性能评价； 2 - In view of the altitude problems of inspecting the weighted average ways of obtaining altitude and the advantages and disadvantages of moving surface interpolation method are talked about through comparison , with which the writer draws a conclusion that moving surface interpolation method is suitable to be applied for the dynamic state inspection places , , moreover the key technology about the dynamic slate inspection is also taken into consideration , which includes digital camera and types of camera lens , the cause of camera lens distortion and the fundamental determining principle , the gain of image coordinate and the realization of time synchronization
针对检定点高程问题，分析比较了获取高程的加权平均法和移动曲而内插法的优缺点，得出移动曲面内插法适合用于动态检定场的结论。特别是针对动态检定的关键技术给予了相关研究，内容涉及：数码相机及相机镜头的选型，相机畸变差产生原因及测定的基本原理，像片坐标获取以及时间同步实现，得出结论：利用gpsoem板的秒脉冲( 1pps )输出特性，能够实现两台数码相机与gps接收机时间同步，满足动态检定指标要求。
