问题描述
我有一组从 OpenCV FAST
角检测功能输出的 2D图像
关键点。使用 Asus Xtion I
也具有已知所有相机校准参数的时间同步深度图。使用这个信息,我想在 OpenCV中提取一组
3D
坐标(点云)。
任何人都可以给我一些关于如何做的指示?在此先感谢!
尼古拉斯·巴瑞斯创造了类似Kinect的深度传感器一个伟大的教程。
我会复制&粘贴最重要的部分:
I have a set of 2D image
keypoints that are outputted from the OpenCV FAST
corner detection function. Using an Asus Xtion I
also have a time-synchronised depth map with all camera calibration parameters known. Using this information I would like to extract a set of 3D
coordinates (point cloud) in OpenCV.
Can anyone give me any pointers regarding how to do so? Thanks in advance!
Nicolas Burrus has created a great tutorial for Depth Sensors like Kinect.

I'll copy & paste the most important parts:
If you are further interested in stereo mapping (values for kinect):
这篇关于提取2D图像点,深度图和相机校准矩阵提取3D坐标的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持!
