CCS/AWR1642BOOST: Some parameter settings about clustering

Hi,

I am currently researching mmwave_automotive_toolbox_2_4_7, lab0002_short_range_radar project.

I don't know about some internal parameter settings for clustering, I hope I can have a detailed introduction.

1. About the weight design

Why is the weight set to 1.3, is there any reason?

2. About the size problem

In clusteringDBscan_calcInfoFixed, if one of xSize or ySize is 0, it will be replaced by 3* resolution. I want to ask why it is 3* resolution, not 2* resolution or other.

thank you

    Hi,

    Regading question 1, could you point to the specific function where you have seen these settings?

    Regarding the resolution setting, xSize or ySize will only be zero if there is a single point in the cluster (which can occur for objects that are far away). In such a case, we need to set a minimum size for the object, and as such a value of '3*resolution' was used.   In experiments this number seemed to work well. However, you can try other numbers like '2*resolution', etc.

    Regards
