推荐答案

你好，



基本上你需要知道相机与物体之间相当准确的距离和角度从相机镜头到物体的顶部。然后，您可以使用简单的三角学来计算高度。请参阅[ ^ ]文章或此[ ^ ]或此[ ^ ]了解更多详情。



问候，

Hello,

Basically you need to know the fairly accurate distance between the camera and the object and the angle to the top of object from camera lens. Then you can use simple trigonometry to compute the height. See this[^] article or this[^] or this[^] for more details.
