Problems solved by technology

[0007] The technical problem to be solved by the present invention is a projector system equipped with a camera to automatically capture the sound source, which combines the sound source collection algorithm and the 360-degree intelligent capture system of the camera to more accurately identify the position of the speaker and avoid people around Misjudgment caused by the sound, and the pickup effectively eliminates the speaker echo and removes the inner cavity noise of the projector

Abstract

The invention discloses a projector system with a camera capable of automatically capturing a sound source, which comprises a projector integrated with a 360-degree intelligent rotary camera, the projector is provided with a pickup system arranged in an array, the pickup system acquires a surrounding sound source and obtains the difference between the azimuth angle of the sound source and a reference angle 0 to obtain the angle value of the sound source, and the intelligent rotary camera drives and controls the rotation angle through a stepping motor driving system according to the obtained angle value of the sound source. The projector system is applied to a remote projection interaction system, the projector is integrated with the 360-degree intelligent rotary camera, when the pickup system picks up the sound of a spokesman, the projector system calculates the azimuth angle, the camera intelligently rotates to capture the image of the spokesman, and a remote system can accurately and timely see the speaking action of the spokesman and stores the sound and image.

Description

technical field [0001] The invention relates to the field of projectors, in particular to a projector system with a camera automatically capturing a sound source. Background technique [0002] The existing product is called voice tracking camera, which is a new species of video conference camera. The video conference camera has a built-in pickup, which will automatically track the conference speaker according to the speaker's voice orientation. Domestic video conference cameras and video conference systems are still relatively rare, which is also the trend of automatic tracking cameras for video conferences in the future. [0003] The disadvantages of the prior art are as follows: [0004] First, the voice acquisition has poor effect in dealing with environmental noise and speaker echo, because the product is only a voice tracking camera, and there is no fixed speaker and cavity environment processing, especially inside the projector, which integrates the sound of speakers ...
