According to reports, researchers at the Ishikawa Research Laboratory of the University of Tokyo in Japan have developed a new type of PTZ camera system that can track fast-moving ball tracks in real time with “amazing†high accuracy and automatically keep moving objects in In the middle of the picture, the high-quality demand for shooting video is matched with international top sports events such as the Olympics or the World Cup.
This "1 millisecond auto pan/tilt system" was named because it uses a 1000 fps visual target locking system, and the built-in galvo mirror does not react more than 3.5 milliseconds to the speed of the object or the change in trajectory. The two mirrors can be moved 60 degrees horizontally and vertically during this time, and the image is bounced back to the stationary high-speed camera in real time.
In fact, although ultra-slow and close-up shots are very precious for the event broadcast, it is difficult for photographers to use the camera to continuously lock a player or a flying ball or other dynamic object. The currently used method is to move the camera at a slow speed in a wide-angle view to achieve continuous tracking of specific players and balls.
Although this is not the first PTZ camera system ever developed, the new system can control the camera's locking point in real time in milliseconds. A general pan/tilt camera is mounted on a rotatable base with a two-axis transmission that must simultaneously control the base and the camera. For the millimeter-controlled pan/tilt system, the weight of the rotating parts must be minimized as much as possible. Therefore, the researchers fixed the camera, and the locking control device using the rotating mirror was installed next to the camera to control the camera with two mirrors. Lock point. The video provided by the research lab clearly demonstrates the tracking of the high-speed table tennis trajectory by the new pan-tilt camera system. In the whole process, the jumping ping-pong ball has been in the center of the screen, and the rotation direction of the ball is also clear at a glance.
