怀疑在相机校准

本文介绍了怀疑在相机校准的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 29岁程序员，3月因学历无情被辞！ 我正在开发一个基于机器视觉的项目。使用具有高分辨率针孔相机的广角镜头。 工作距离：相机和物体之间的距离。 分辨率将接近10MP。图像大小可以是3656像素宽度和2740像素高度。 项目要求如下所述 我的工作距离必须接近5米。 为避免相机中的镜头失真，请使用OpenCV进行相机校准 以下提及的是我对此相机校准的疑问。 由于摄像机倾斜角度为13度，因此工作距离为5米， 解决方案 div> 这两个问题的答案都不是。当假设针孔相机模型时，相机校准基本上找出焦距和像素平面之间的关系;和可选（如果您需要广角镜头），径向变形。这些关系与相机在世界上的位置无关。 顺便说一下，我看到你标记为 matlab ：我可以推荐 MATLAB的相机校准工具箱作为校准相机的一个很好的简单方法。它会引导你完成整个过程。 I am working on a project based on machine vision . Wide angle lens with high resolution pinhole camera is being used.Working distance : Distance between Camera and object .The resolution will be nearly 10MP. The image size may be 3656 pixel width and 2740 pixel height.The project requirements are as mentioned belowMy working distance must be nearly 5metres.The camera needs to be tilted at an angle of 13 degree.To avoid lens distortion in camera I do camera calibration using OpenCV.Below mentioned are my doubts pertaining to this camera calibrationSince the working distance is 5 meters, should the camera calibration too be done with the same distance?Since the camera is tilted by an angle 13deg in the application ,is it necessary to do the calibration too with the camera tilted at respective angle? 解决方案 The answer is no to both questions. Camera calibration essentially finds the relationship between the focal length and the pixel plane when assuming the pinhole camera model; and optionally (as you will require due to your wide angle lens), radial distortion. These relationships are independent of the position of the camera in the world.By the way, I see you tagged this as matlab: I can recommend the Camera Calibration Toolbox for MATLAB as a nice easy way of calibrating cameras. It guides you through process nicely. 这篇关于怀疑在相机校准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！ 上岸，阿里云！
