Tool/software:

Hi,

In the gtrack_unitScore function,

xyVelocity = sqrtf(velx*velx + vely*vely);

        if(xyVelocity < 0.1f)
            isUnitStatic = true;
        else
            isUnitStatic = false;

From the function, we can see that if xyVelocity is less than 0.1. We can consider the object as static one, or it is dynamic object. Whther The prerequisite is that the radar is static, is that right? If the radar is moving,the condition should be changed, is that right?

Hi Rata,

Yes this is correct. The velocity is relative to the sensor, so if the sensor is moving and an object is static, it will appear to be moving to the radar device.

Hi Tim，

Now if we want to use the code as parking radar.In this situation, the radar is moving, is there any place to be modified for this application?Or is there any other code that can be applied in parking?

Hi,

Our mmw_demo is meant for a parking application or for blind spot detection. This demo is range-doppler based.

If the radar is moving and you wish to know the velocities of the tracks, you will have to perform that math to find the delta yourself given the speed of the radar sensor.

Hi Tim，

Thanks for your reply. If we can get the speed of the radar sensor, then we change the judging condition for static and dynamic objects, not only by doppler speed, but by doppler speed and radar speed, the gtrack code can also be used for track, is that right?

Yes,

The grtrack lib will just need an input of the radar velocities to account for this, yes.

Hi Tim,

Thanks for your reply. In our test condition, the radar is moving, if we don't change the gtrack code at all, the actually stationary objects, such as stopped cars, will be considered as dynamic objects, it is just relative motion in fact, but they are processed as dynamic objects in the gtrack code. Is it reasonable?

Hi,

Yes, that is correct.
