how can I get the  
distance (meter)  
position(x,y,z)  
and velocity(k/m )  
for every object in terminal printed when I run the detector for yolov5 ?[https://github.com/stereolabs/zed-examples/blob/master/object%20detection/custom%20detector/python/pytorch\_yolov5/detector.py](https://github.com/stereolabs/zed-examples/blob/master/object%20detection/custom%20detector/python/pytorch_yolov5/detector.py)

what I made I tried to print the distance for all the object detected already in the scene  
I could find out and print in terminal all the information about all the object expect the distance

as you can see here  
I just got the distacne for one point?

how can I get the distance for all the object!

another thing is that why is it slow why I run yolov5 detector???

please help?

HI @joeurban  
you can find the information in the `object` variable:  
[https://www.stereolabs.com/docs/api/python/classpyzed\_1\_1sl\_1\_1ObjectData.html](https://www.stereolabs.com/docs/api/python/classpyzed_1_1sl_1_1ObjectData.html)

The `distance` that you are calculating with the Euclidean Distance formula there is the distance of the central point of the image

Why is it slow? Yolov5 detector is slow ?

YoloV5 is faster if compiled with CUDA and optimized for the GPU that you are using
