摘要
针对光学镜头在检测小口径矩形管道内表面不规则缺损面积时,因探测镜头的空间自由度大,不能人为控制镜头探测拍摄时摄像镜头的位置和倾斜角度的难题,提出了一种矩形管道内表面不规则图像面积的图形梯形估算模型,通过实现应用表明,运用该估算模型进行不规则图形面积计算时,检测精度高,处理速度快,具有较好的工程应用价值。
When optical scope detects the irregular defective area on the internal surface of small-bore rectangular pipeline, be- cause of the high degree of spatial freedom of the detective scope, the position and angle of inclination of camera cannot be controlled artificially when detection. A trapezoid estimation model for the internal surface of rectangular pipeline irregular figure area is put for- ward. Through the practical application, it is shown that when applying the estimation calculation model to calculate the irregular fig- ure area, the detective accuracy is high and the processiug rate is fast, which has better engineering application value.
