| 摘 要： | 对大型农用拖拉机进行导航是目前精准农业的发展方向。对拖拉机导航所涉及的UTM坐标系和空间直角坐标系的投影转换进行了分析,并给出了在这两种坐标系中计算点到空间直线距离的算法。通过编程比较和实际的测量表明,在求解导航距离时空间直角坐标系比UTM坐标系误差大很多,不适合高精度的农机导航中。

| Abstract: | Guidance for large scale agriculture tractor was the develop direction in current PA. The coordinate conversion between Universal Transverse Mercator coordinate was analyzed,and two arithmetic about distance between point to line in that two different coordinate were get. It proved that the error in space rectangular coordinate was bigger than in UTM coordinate through program and test. So the space rectangular coordinate was not suit for guidance. |
