People detection application

Other Parts Discussed in Thread: IWR1642, IWR1443, IWR1642BOOST

Hello John,

Since you are looking at two different types of applications I will split this thread into two threads so each application can be addressed appropriately.

Regards,
John

Original post copied below:

I just take apart in mmWave event in Shenzhen. And I get so much information and  it is more than I think. Thanks again.

Actrully, I am very now in this field. And I am a embedded hardware and software engineer. But I didn't have enough knowledge in this field, especially the knowledge about how to design antenna. It is same very complicat. I have two needs now. 

1st Application: I want to design a better sensor to replace ultrasonic solid level meter. Get more accurate position and more intuitive surface of solid(like the top shape of coal in coal bunker).

2nd Application: If it is possible to detect if there is a person in toilet seat. And for economic consideration, if it is posible to detect many toilet seat. 

For my usage, it there is any paper or docs in your website can let me know more about it. I want to know more about how to design the antena and if there is any datasheet or application can teach me.

Thanks very much.

As a engineer, I am very pround about it. I think it is the best career to create things to make the world become better.

    Hi John,

    The original thread (link: e2e.ti.com/.../2691766 ) will address the question about the solid level meter application.

    This current thread will address the question about the people detection.

    Regards,

    Hi John,

    As for detecting people on a toilet or any location - you will be interested in the People Counting demo or the occupancy demo. 

    The People Counting demo can be programmed to monitor subzones - each subzone can be located in an area of interest. This demo tracks each person individually, and provides state information for each target consisting of location, velocity, and acceleration. It requires an IWR1642. See 2:05 in this video for an example of tracking people in a shower.

    The occupancy demo monitors many different zones, and knows when there are radar detection points in these zones. It can run on the IWR1443 or 1642; the IWR1443 also gives elevation information. It does not have information about individual targets, but requires much less processing.

    Antenna design is difficult, and we do not have any resources to help you learn how to design antennas.

    Regards,

    Justin

    Hi Justin,
    Your reply is very helpful. I will get a IWR1642BOOST to test it. Thanks for your help.
    I know mmWave is a complicated problem. But it is a useful and interesting problem and I believe it will have many application. Wish we can get a cheaper but better mmWave chip.(It is still a little expensive)
    I will make some test and prepare some application for it.
    Thanks. Have a good day.
