寻找直线与直线之间的交点我们在matlab中的图
我们正在做一个关于耳朵识别的项目。我们已经得到了图中耳朵的边缘已经找到了每个的质心。我们还以 10 度间隔从质心绘制了线。现在我们需要知道如何在 matlab 中找到这些线与我们耳朵边缘的交点。
We are doing a project on ear recognition. We have got the edges of the ear in a figure & have found the centroid of each. We have also drawn lines from the centroid at 10 degree intervals. Now we need to know how to find the points of intersection of these lines with our ear edges in matlab.

MATLAB Central File Exchange 上有很多关于查找曲线交点的提交:
快速且稳健的曲线交点
如果您的耳朵边缘表示为曲线,并且您可以为每条线计算至少 2 个点,则可以使用此功能非常快速地找到它们的交点。
There is great submission on MATLAB Central File Exchange to find curves intersections:
Fast and Robust Curve Intersections
If your ear edge represented as curve and you can calculate at least 2 points for each lines, you can find their intersections very fast with this function.
