给定图像，您将如何找到物体的高度? [英] How would you find the height of objects given an image?

问题描述

这不完全是一个编程问题.我只是想知道您对数字图像处理中常见问题的处理方法.

This isn't exactly a programming question exactly. I just want to know what your approach would be to a common problem in Digital image processing.

假设您有一张 jpg 格式的几棵树的图像.您将如何找到每棵树的高度?照片是您唯一的输入.

Let's say you have an image of a few trees in say jpg format. How would you go about finding the heights of each of these trees? The photo is the only input you have.

我想知道你不必编码的方法.因此，您的答案是否含糊或非 DIP-ish 都没关系.

I want to know the approaches you have not to code. So it doesn't matter if your answers are vague, or non DIP-ish.

小修正:高度不必是树的实际高度.高度可以采用任何比例.但应该与图片中的所有对象保持一致.

Small correction : The height need not be the actual height of the tree. The height can be taken to any scale. But should be consistent to all objects in the pic.

推荐答案

是的，这是可能的.您所描述的是围绕它的整个行业，称为 摄影测量

Yes it is possible. What you are describing has an entire industry around it, called Photogrammetry
