Hi，

I have IWR1443 BOOST and MMWCAS-RF-EVM. The routine used by MMWCAS-RF-EVM is 4chip_cascade_MIMO_example .Use them to measure the ceiling at the same time ，but iwr1443 has more points.Could you tell the reason of it?The picture on the left is the use of MMWCAS-RF-EVM, and the picture on the right is the use of IWR1443.

Hi,

I think that the IWR1443 display overlaps the point cloud from several frames. The IWR1443 should not be able to detect in a single frame so many points.

Could you please double check the configuration

Thank you
Cesar

Hi,

Where should I see how many frames of point cloud are displayed in rviz?

Hi.

Here is some additional information

“ RVIZ has a feature where points can decay over time, allowing points to accumulate and build a better “picture” of the world. This setting is called “Decay Time”. You can set this value to 0 for real-time points. Change the highlighted value in the image below”

I noticed that in your picture the Decay Time is 0.25

I will close this thread now.

If you have new questions please start a new thread

Thank you
