【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。更多还原

【Abstract】 When optical scope detects the irregular defective area on the internal surface of small-bore rectangular pipeline,because 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 forward.Through the practical application,it is shown that when applying the estimation calculation model to calculate the irregular figure area,the detective accuracy is high and the processing rate is fast,which has better engineering application value.更多还原
