AWRL6432BOOST: Tracked target dimensions

Hi, TI experts,

I would like to ask about tracked target dimensions.

When I checked the motion_and_presence_detection SDK code (MMWAVE_L_SDK_05_04_00_01), the dim[] array below of the GTRACK_targetDesc structure seems to mean the target dimension, is that correct?

/** @brief Estimated target dimensions: depth, width, [height], doppler */
float dim[GTRACK_MEASUREMENT_VECTOR_SIZE];

Are they all in meter units?

For GTRACK_3D, is the dim[] array value a target dimension in meter units of y (range direction), x (width direction), z (height direction), and v (radial velocity)?

I want to get the size of a person who is walking speed or a vehicle that is driving slowly, what is the sizing accuracy?
I think the more points allocated to the target, the more accurate it will be, how many points will be needed?

Hi, there:

Thank you for reaching out. Can you let me know what application it is for so we can bring the right team to help? Is it for people tracking? or car tracking?

Best,

Zigang

Hi, Zigang,

Thank you for fast response.

The application is for built in CAM use in a stationary vehicle.

Our customers want to detect motion and dimensions both of people and cars. But they also want to count them...

I would appreciate it if I could get helpful advise.

Best,

Taeyoon

Hi Taeyoon,

You are correct, in the GTRACK_targetDesc struct, the dim[] variable does represent the estimated target dimensions: depth, width, [height], doppler. The units for these are in meters.

In regards to the accuracy, this is not something we have clear characteristics of since the performance is heavily dependent on configuration and power consumption.

I highly recommend taking a look at the Parameter Tuning Guide for MPD and Group Tracker Parameter Tuning Guide.

Let me know if you have any other questions.

Best,

Vignesh K.
