[英]Find movement distance between two frames -- python
I have a short video of a moving object.我有一个移动物体的短视频。 for some reason I need to estimate the object's movement distance between two specific frames.
出于某种原因,我需要估计两个特定帧之间对象的移动距离。 It is not necessary to be exact.
没有必要精确。 Does anyone know how I can do this in python and opencv or any image processing library?
有谁知道我如何在 python 和 opencv 或任何图像处理库中做到这一点? Thanks
谢谢
I don't know in opencv, there is for sure something similar but you can easily do it with scikit-image
module.我不知道在 opencv 中,肯定有类似的东西,但您可以使用
scikit-image
模块轻松完成。 I do it on a regular basis to align frames.我定期这样做以对齐框架。
See this example here:在此处查看此示例:

EDIT: I found something very similar in opencv here编辑:我在这里的 opencv 中发现了一些非常相似的东西
