“视差图"的定义是什么? [英] What is the definition of a "disparity map"?

问题描述

我被要求实现基于边缘的视差图，但是我根本不了解什么是视差图. 视差图"的定义是什么?

I've been asked to implement an edge-based disparity map, but I fundamentally don't understand what a disparity map is. What is the definition of a "disparity map"?

推荐答案

视差图是指一对立体图像之间的视在像素差异或运动.要体验这种情况，请尝试合上一只眼睛，然后在另一只眼睛同时迅速合上.靠近您的物体似乎跳了很大的距离，而距离较远的物体几乎不会移动.那个动静就是悬殊.

Disparity map refers to the apparent pixel difference or motion between a pair of stereo images. To experience this, try closing one of your eyes and then rapidly close it while opening the other. Objects that are close to you will appear to jump a significant distance while objects further away will move very little. That motion is the disparity.

在一对源自立体摄像机的图像中，您可以测量每个点的视在运动，并根据测量结果制作强度图像.

In a pair of images derived from stereo cameras, you can measure the apparent motion in pixels for every point and make an intensity image out of the measurements.

例如，请参见此.您可以看到前景中的对象更亮，表示运动更大，距离更短.

See this for an example. You can see the objects in the foreground are brighter, denoting greater motion and lesser distance.
