<p dir="auto">障碍物的轮廓非常不清楚，而且小车的位置总是发生漂移，是参数配置有问题吗？</p>
<p dir="auto">谢谢。</p>

确实旋转方向也变了，翻转参数应该设置成true，感谢！</p>

嗯，考虑上下反了的话，与小强默认tf配置，x轴y轴应该不变，z轴应该降低了10公分。<br />
然后是延x轴旋转180°。</p>
<p dir="auto">请帮我看一下，最终tf 参数是不是改成这样？</p>

感谢！<br />
确实是安反了，为了能安装机械臂，那是不是需要设置TF，旋转Z轴180°</p>

<p dir="auto">感谢回复。</p>
<p dir="auto">怎么确认里程计是否准确？需要做校准工作吗？<br />
我使用的是小强pro，雷达已经安装好了，应该不会装反吧？再附发一张小强的照片。</p>
