图像透视校正在移动机器人视觉识别中的应用

The Application of Image Perspective Correction in Mobile Robot Visual Recognition

文章以第44届世界技能大赛移动机器人项目中的网格码识别为例,使用NI myRIO作为核心控制器,在LABVIEW集成开发环境下,对摄像头采集的图像进行二值化,提取网格码所在图像区域,运用图像透视校正的原理进行校正,对校正后的网格码像素点进行统计从而识别网格码信息。经实践,该方法对摄像头没有严格的位置角度要求,可以快速准确地识别网格码,图像透视校正在移动机器人视觉识别中有很好的使用效果。

This paper, taking the grid code recognition in the 44 th World skills Competition mobile robot project as an example,uses NI myRIO as the core controller, under the LABVIEW integrated development environment, the image captured by the camera is binarized, the image area where the grid code is located is extracted, corrected by the principle of image perspective correction, and the corrected grid code pixels are counted to identify the grid code information. Through practice, this method has no strict position and angle requirements for the camera, and can identify the grid code quickly and accurately. The image perspective correction has a good effect in the visual recognition of mobile robot.
