Abstract

The invention relates to a shooting device. An automatic tracking shooting device comprises a camera and a camera holder, wherein the camera is installed in front of a black board and is arranged on the camera holder. The automatic tracking shooting device further comprises a master control processing chip and two infrared signal emitter groups, each infrared signal emitter group comprises a plurality of infrared signal emitters, the master control processing chip is installed inside the camera holder, the first infrared signal emitter group is transversely fixed below the black board along the black board, the second infrared signal emitter group is fixed on a ceiling in front of and above the black board, and the infrared signal emitters in the second infrared signal emitter group correspond to the infrared signal emitters in the first infrared signal emitter group one to one in position. The automatic tracking shooting device changes installation positions of the infrared signal emitters, lowers the starting frequency of the camera holder, and therefore enables shot images to be smooth.

Description

technical field

[0001] The present invention relates to imaging devices. Background technique

[0002] At present, in the case of relatively scarce educational resources, distance education and quality courses have become a fashionable solution. However, due to insufficient network bandwidth and other reasons, distance teaching is still difficult to popularize on a large scale. Relatively speaking, the recording of high-quality courses has become the mainstream solution. The recording of excellent courses must have a good effect. In addition to the relatively high requirements for the clarity of the recording screen, the automatic tracking of the teacher by the camera is also an indispensable function to make the screen look more humane.

[0003] At present, the camera method of the excellent courses is mainly the real-time wireless docking tracking camera method. The camera method is to let the teacher wear an infrared signal emitting device, detect and locate the infrare...
