The present disclosure relates to a target tracking method, device, medium and apparatus, belongs to the technical field of computers, and can ensure the completeness of tracking. The target tracking method comprises performing object detection on all telephoto image frames captured by telephoto cameras in a multi-camera system, and constructing a detection point set based on object detection result for each frame of the telephoto image; selecting a target tracking point from each detection point set based on the starting tracking point; and connecting the selected target tracking points as a tracking sequence for the starting tracking point.

Target tracking method, device, medium and apparatus

The present disclosure relates to a focus tracking system and method. The system comprises: a primary camera comprising a first focus adjustable lens and a first focus adjusting servo motor driving the first focus adjustable lens to perform focus adjusting; a secondary camera comprising a second focus adjustable lens and a second focus adjusting servo motor driving the second focus adjustable lens to perform focus adjusting, coded aperture is installed inside the second focus adjustable lens, the secondary and primary camera have equivalent optical parameters; a synchronization system performing frame level synchronization between images of the primary and secondary camera to obtain frame-level synchronized primary and secondary camera images; a focus control system calculating out-of-focus offset utilizing coded patterns of the coded aperture and out-of-focus images in the frame-level synchronized secondary camera images, sending focus adjusting signals to the first and second focus adjusting servo motor based on the out-of-focus offset.
