摘要
摄像机拍摄图像时,会使物体在同一水平面上的边缘呈现曲线形状,给图像处理方法的实现和图像边缘位置的定位带来不便。这篇文章研究了把图像的曲线边缘变为直线边缘的图像平视化处理方法,推导了像素点和空间点的对应关系公式,陈述了图像平视化处理的思路,并对现场采集的图像进行了平视化处理。通过试验,这篇文章的平视化方法取得了较好的效果。
When the video camera image,make an object at the same horizontal plane has a edge of curve shape,which is difficult to process and locate where the image edge pixel location. This article researches on how to make the curve edge translated into a straight line,introduces the measure formula between the pixel point and the space point,describes image processing ideas,and proved that this method can get better results by experiment.
