基于TMS320DM642的农业机器人视觉导航路径检测（Identifying the Navigation Route Based on TMS320DM642 for Agriculture Visual Robot）
机器人 自定位 视觉导航
2009/8/11
在农田非结构化自然环境下，通过机器视觉提取导航线的处理算法，利用透视投影变换得到摄像机相对于导航路径的偏移距离和偏移角，成功地在TMS320DM642系统上得到实现，并对程序进行了基于C语言的代码优化。试验结果表明，偏移角的最大误差为2°，横向偏移距离最大误差为5cm。
农林环境机器视觉导航路径生成算法及应用（Algorithms of Path Guidance Line Based on Computer Vision and Their Applications in Agriculture and Forestry Environment）
