我这里使用mid-70在室内检测物体,在检测到的物体后方发现比较密集的散点(效果在附件的截图中)。其中黄色框为检测到的黑板,黑板到墙之间有比较密集的散点。请问各位大佬这是正常情况吗?

这黄色散点是否是在黑色黑板的边框周围,能以第三方角度拍一张雷达与黑板的现场图片吗?

建议你看下官方关于Tag信息的帖子,猜测是由于远近差距造成的错误点信息,我也遇到了同样的问题

同学您好,了解到您的问题;
大多数的激光雷达在长时间积分下都会有;拉丝噪点产生的原理是由于雷达光斑是一个面,在进行深度解算时候,边缘部分的深度有时候在临界情况算不准;
解决方案:您可以通过tag值滤除置信度较低的点来达到滤除噪点的效果。
参考: https://forum.livoxtech.com/foru ... d=222&highlight=tag

希望对您有所帮助。
