Hello everyone, i have met a trouble with calculating zoom size of camera. I am detecting object from streams of camera PTZ model Q6135-LE, but when i detected i have got x_center and y_center points of that object, but i don't know how to use camera to zoom with size fitting same as size of object, although i can take camera to focus correctly into this object in center point of camera with API: http://{device}/axis-cgi/com/ptz.cgi?center=x,y with x,y. However, i cannot be able to calculate zoom size accurately. Please help me solve this problem. Thanks u |

I think you should also get the object size then compare to the whole image size, you should have a brief ratio of zoom, then use the areazoom |
