What's the difference between AE tracking camera and tracking motion?

1, different concepts.

The tracking camera can automatically identify the image, capture the image as the image moves, identify the movement of the object within the monitoring range, and automatically control the pan/tilt to track the moving object, so that all the actions of the object can be clearly transmitted to the monitor.

Tracking motion is based on the principle of computer graphics, which records the motion state of moving objects (trackers) in the form of images through a plurality of video acquisition devices arranged in space, and then processes the image data with a computer to obtain the spatial coordinates (x, y, z) of different objects (trackers) in different time measurement units.

2. The place is different

Tracking cameras can be placed on the ground. Tracking motion can track cars.

3, the principle is different

Tracking the camera's early shooting, the camera is moving, and the camera's motion data can be deduced in AE later.

Tracking motion is the feature of tracking motion in video, and the purpose of motion tracking is to clearly capture the trajectory of motion.
