AWRL6432BOOST: True ground speed sensor

Poorneka T

Part Number: AWRL6432BOOST

Tool/software:

Hi team,

We are currently working in the true ground speed sensor lab.

We understood that the final velocity out from the lab is arrived by using the RANSAC algorithm.

Please share your views about the following:

  1. The arrived velocity corresponds to a particular point detected in the frame - Is this correct?
  2. Is it possible to get the range, snr and noise details of the arrived velocity?

Any additional insights would be appreciated.

    Hello.

    The arrived velocity corresponds to an average velocity of all the valid points in the scene per frame, and the RANSAC algorithm is used to determine if the point and its corresponding velocity is an outlier or inlier and build a polynomial regression.  Currently, you could look at the uncompressed pointcloud information to get the x, y, z, snr, and noise of all the points in the scene, which are used to compute the velocity.

    Sincerely,

    Santosh

    Hi Santosh,

    Thanks for the reply.

    Can you please look into the below query:

    The RANSAC algorithm uses azimuth and doppler of the detected points as inputs and gives an average velocity of the valid points in each frame.

    In the same way, is it possible to get the average Range and SNR along with the velocity of the valid points from the RANSAC algorithm?

    Thanks in advance.

    Hello.

    The RANSAC-LSQ provides the doppler estimation by generating a best-fit polynomial for the pointcloud data relating the velocity associated with each angle; the RANSAC algorithm by itself is simply a way to eliminate any outlier points and then by building a polynomial based on these points I can estimate the velocity; therefore theoretically something similar could be done for range and/or SNR, but it would have to be a combination of the RANSAC and LSQ algorithms to do so, and not just with the RANSAC algorithm.

    Sincerely,

    Santosh
