IWR1642BOOST: Traffic Monitoring Demo

Nuno Ferreira1

Part Number: IWR1642BOOST

Hello, 

I've recorded data using the Traffic Monitoring Demo. However I'd like to know if the timestamp given by the fHist files can be used as actual datetime for the pointclouds or if its merely for device synchronization.

Another question I have, is if there's a way easier than running the Playback.m file for the recorded data (which for a whole day of data, sometimes gives errors), if I could from the fHist files easily track the number of cars in one of my lanes (my example I used 3 lanes, one on the left for cars exiting the location, one on the middle where no cars passed, and one on the right for cars entering).

Thank you for your time

    Hi Nuno,

    Thanks for your questions. An expert will get back to you next week (please note that Monday, 2nd-Sep is a holiday in the US).

    Thank you for your information, it would be really useful for timestamp purposes. But I think I have noticed that the timestamp in .mat file are only for synchronization purposes, so only my second questions needs answering.

    Thank you once again

    Hello Nuno,

    The fHist doesn't record the lane count information. The fHist file is more useful for users needing to debug the algorithm or review point cloud and tracking behavior. I would recommend that if you're primarily interested in just target count per lane to instead modify the source code to capture that data to a CSV file. The source code is provided in the GUI folder.

    If you're wanting to extract this from existing fHist files then you can use Matlab to open the data files and then write some simple functions to extract the track positions from the structs and then calculate the lane occupancy.

    As is, the playback file is more for users wanting to visualize the fHist and is not suited towards extracting the data you want.
