摘要
使用2部数码相机对海上非合作目标进行定位时,需事先对数码相机进行标定,由于传统的标定法无法满足海上实测需求,本文针对海上非合作目标特点,从线性标定法原理出发,提出一种适合海上非合作目标定位的数码相机标定方法,将需要用到的几枚定焦镜头分别进行内外标定,并记录内外参数,不仅满足了定位需求,而且提高了定位效率。
When using two digital cameras to locate marine non-cooperative targets ,we need calibrate the digital cameras in advance. Because the traditional calibration methods cannot meet the demand at sea, this paper aiming at the feature of marine non-cooperative target, and basing on the linear calibration principle,puts forward a suitable method of digital camera calibration for marine non-cooperative targets. It needs to make a few pieces of fixed-focus cameras inside and outside calibration respectively,and recode the internal and external parameters, this method not only meets the demand of location, but also improves the efficiency of location
