中文说明：完成对图像的逆透视映射变换，需要给出摄像机的高度，视角和最终图片的横向宽度（米）。一旦给定参数准确，即可得到效果很好的逆透视映射变换图片。-Complete the inverse perspective mapping transformation on the image and the need to give the transverse width (m) at the height of the camera, the viewing angle and the final picture. Once given parameters accurately, inverse perspective mapping transformation picture you can get good results.
English Description：
To complete the inverse perspective mapping transformation of the image, we need to give the height of the camera, the angle of view and the transverse width (m) of the final image. Once the given parameters are accurate, we can get a good image of inverse perspective mapping transformation. -Complete the inverse perspective mapping transformation on the image and the need to give the transverse width (m) at the height of the camera, the viewing angle and the final picture. Once given parameters accurately, inverse perspective mapping transformation picture you can get good results.
