投影到3D问题 #110

Closed JiweiMaster closed 1 year ago

JiweiMaster commented 2 years ago

网络输出的车道线，拟合的曲线，可以投影到3D吗？

voldemortX commented 2 years ago

@JiweiMaster 2D车道线检测输出的相当于是 uv 坐标，如果有相机参数和深度信息，可以投影到3D。

这里讲了基本的形式：https://zhuanlan.zhihu.com/p/144307108

实际的相机参数矩阵自由度可能更高，比如内参还可以有axis skew，这取决于你的相机模型。
