ROI
ROI 只允许由一个正方形或矩形组成，整个边缘都位于该正方形或矩形内。如果 ROI 中有多条边，则始终使用根据模型参数找到的最长边进行搜索。
搜索角度的影响
SearchAngle 决定边缘的搜索方向。SearchAngle 必须直接指向边缘。如果不是这种情况，则会在函数中旋转绘制的 ROI，使由绘制的 ROI 角点定义的有向矩形按照 SearchAngle 确定的方向对齐。

ROI
The ROI is only permitted to consist of a square or rectangle within which the entire edge is located. If there are several edges in the ROI, the longest edge found on the basis of the model parameters is always used for the search.
Impact of SearchAngle
SearchAngle determines the search direction of the edge. SearchAngle must point directly to the edge. If this is not the case, the drawn ROI is rotated in the function so that a directed rectangle defined by the corner points of the drawn ROI is aligned as determined by SearchAngle.
