IWR1642BOOST: Working in basement and underground parking spots and immune to false triggering by movement of leaves

Hello,

Please refer to the traffic monitoring TI Design which gives you some more information about the mounting height and angle to determine the sensor area coverage: http://www.ti.com/tool/TIDEP-0090

Also refer to the antenna database to understand the FoV of the antenna: http://dev.ti.com/tirex/explore/node?node=AKu-aTm5FIcxlwZJU1pLBw__VLyFKFf__LATEST. You should be able to calculate the expected area coverage given your desired mounting height and sensor orientation.

Using the gtrack algorithm, filtering out movement from leaves and fluttering objects can be done. An example is demonstrated here: http://dev.ti.com/tirex/explore/node?node=AMn8XKVsX657Env-K6JAQg__VLyFKFf__LATEST

We have not used 1843 specifically for parking spot detection however it should be achievable to some extent. The number of cars and the variation from outdoor to indoor garage scenarios would require development and testing for your applicatino. I would also recommend you look at the area scanner demo which could also be a relevant starting point: http://dev.ti.com/tirex/explore/node?node=AD6F02XtKZMeXTYUwLQKMw__VLyFKFf__LATEST

Hello Amanda,

Firstly thanks for the valuable links.

I read them and understood the various concepts.

Now another customer approached us with a requirement to count humans outdoor and indoor in order to calculate crowd density and ensure social distancing. They have a big requirement as they are planing to deploy it across the city both outdoor and indoor without using cameras.

I think IWR1843BOOST EVM will be a good starting point for me to show them POC.

My only question is: Can IWR1843BOOST EVM be used for detecting, counting humans in an outdoor environment? One of the links given by you states - "mmWave Sensor to pinpoint location of objects in 100° field of view over a range of 5 m to 180 m". So, my understanding is that the sensor can be used to detect, locate humans in outdoor environments like city centre.

Please comment and give your opinion if my understanding is correct or not regarding using the sensor outdoor for detecting and counting humans.

Thanks and Regards,

Sritam Paltasingh.
