一种检测摄像机与被测物间三维轴线求解方法

摘要

Aiming at the complex problem of calculating three-dimensional axis between the detecting camera and the ob-ject under test in the commodity excessive packing intellectual detection system based on three-dimensional scanning,a new method is proposed to calculate three-dimensional axis between the detecting camera and the object under test. It takes checker-board as marking plate,makes use of OpenCV to recognize and deal with the marking images,realizes coordinate conversion from 2D to 3D and spatial point reconstruction according to the principle of 3D reconstruction,and implements the calculation of 3D axis between the detecting camera and the object under test. The experiment results show that the structure of measuring device is simple,it is unnecessary to make edge detection for the marks in the process of transform. The method,which has less calculated amount and high measuring efficiency,can fulfill the precision demands of the system and reduce measuring com-plexity.%针对基于三维扫描的商品过度包装智能检测系统中检测摄像机与被测物间三维轴线求解复杂的问题,提出一种在过度包装检测系统中检测摄像机与被测物间三维轴线求解方法.该方法利用棋盘格做标记板,在计算机上利用OpenCV对标记图像进行识别处理,利用三维重建原理对坐标进行二维到三维的变换和空间点重建,实现三维扫描下摄像机与被测物之间的三维轴线求解.在实验中,该方法测试数据达到该系统对精度的要求.所提方法中测量装置结构简单,在转换过程中不需要对标记进行边缘检测,减少了计算量,同时使测量效率得到提高,降低求解的复杂程度.
