你好,
我正在使用英特尔实感D435,当我拍照时,我总是在图像的边框上出现错误的信号,就像我附加到你这个案例的图像一样,在我用蓝色环绕的部分。 相机认为这些部件非常深,产生的点云非常糟糕,我总是需要手动清洁所产生的层的这些部分。 我有办法避免这种情况吗? 对我来说,正如我所知,我想要捕获的距离比1m更近,解决方案是创建一个只有信号被认为接近1m的层文件,也就是说指定最大深度为1m。 可能吗? 谢谢, 灵光 Capture0.PNG 91.9 K. 以上来自于谷歌翻译 以下为原文 Hello, I am using Intel RealSense D435, and when I take picture I always get wrong signal on the border of the image, like the image I attached you to this case, in the part I surrounded in blue. The camera thinks that these parts are very deep, and the resulting point cloud is pretty bad, and I always need to clean manually these parts of the resulting ply. I there a way to avoid this? For me, as I know that what I want to capture is nearer than 1m, a solution would be to create a ply file with only the signal considered as closer to 1m, that is do say specify that the max depth is 1m. Is it possible? Thank you, Emmanuel

如果您只想要考虑某个MaxZ值下的深度值,Clamp MaxZ可能会满足您的需求。

如果问题出在跑步者背后的区域(看起来像是使用计算机的龙),这可能与D435的“RMS错误”因素有关。 被分析深度的距离越大,深度噪声或RMS误差越大。 由于D435的硬件设计,D435具有比D415更大的噪声距离。 您可以尝试更改Disparity Shift设置。 随着Disparity Shift增加,MaxZ减少。 因此,这可能是您设置最大距离的好方法。 左键单击下面的图像以全尺寸查看它们。 以上来自于谷歌翻译 以下为原文 If the problem is with the area behind the running man (which looks like a dragon using a computer), this may be related to the D435's 'RMS error' factor. The greater the distance of the depth being analyzed, the greater the depth noise, or RMS error, is. The D435 has more noise over distance than the D415 has, due to the hardware design of the D435. You could try changing the Disparity Shift setting. As Disparity Shift is increased, the MaxZ reduces. So this may be a good way for you to set a maximum distance.
