I am trying to detect and track tennis ball during a Padel game. I have only one camera ( 30-50 fps) recording video from one end of the court. The ball is small and moving fast. I am using yolo v3 to detect the ball but it fails to detect it most of the time. Is there any approach that can be used in this kind of situation?
detection of tennis ball and tracking was already done by some researchers. it is better you can use their ideas and extend the work. the work is better done in OPENCV. you can go through the you tube videos and the code you can get it freely from github.
if you want the tennis ball to be detected in such situations, you can consider by recommendation. but if you want to use YOLO for detection of ball, sorry i dont have any answer.
thank you.
Hi
There are different solutions here:
1. I do not know what kind of camera you have ? roller or global shutter? but probably you need to increase the frame rate, if possible;
2. Otherwise go for a pixy cam (https://pixycam.com/pixy-cmucam5/), it has been designed for this kind of tasks, track simple objects with a single color - and it is affordable. However it depends also of the distance of the cam with respect to the object to be tracked : few meters are ok but 10 or 15 meters i am not sure;
3. Much More expensive are event cameras but they are doing very well for tracking fast objects - look at this video in which in drone is avoiding a football ball https://www.youtube.com/watch?v=sbJAi6SXOQw&t=10s
Event cameras are quite new and require new algorithms as well - very promising field in computer vision!
Hope that help
