利用相机标定进行的空间定位

Spatial Positioning Using Camera Calibration

研究者通过使用针孔相机模型及凸透镜成像原理,对手机相机进行模拟,仅利用一把直尺,即可计算手机相册中实际物体的三维位置,其中最重要的创新点就是对相机标定方法的改进。本文讲述了研究者所作创新实验的方法和步骤,最终通过固定小球位置,拍摄小球图像分析其位置,比较分析结果与实际坐标,发现二者误差均在5%以下。

The researchers use pinhole camera model and convex lens imaging principle to simulate the mobile phone camera.Only one ruler can calculate the three-dimensional position of the actual object in the mobile phone album.The most important innovation is the improvement of camera calibration method.This paper describes the methods and steps of innovative experiments made by researchers.Finally,the position of the ball is analyzed by fixing the position of the ball and shooting the ball image.The error between the analysis results and the actual coordinates is less than 5%.
