Problems solved by technology

Various devices are mostly clamped or hung on the ground and fixed in a certain position. It is necessary to manually move the camera position and adjust the focal length of the far and near scenes, which greatly affects the fluency of live video and the viewing experience of users.
And almost all of them are monocular cameras, which cannot meet the needs of more and more users for the immersive experience of three-dimensional live broadcast

Embodiment

[0032] One, at first introduce main method principle of the present invention.

[0033] The present invention designs a traceable portable three-dimensional live broadcast intelligent robot, and the specific functions are realized as follows:

[0034] First, the device integrates NMF face recognition based on α divergence and improved tracking algorithm based on Kalman filter, automatic calibration algorithm, table lookup and anti-shake algorithm, and automatically or semi-automatically detect and track faces. There are two types The method, first, the device automatically detects the face in the shooting screen, and tracks the face after the recognition is completed, and second, the device automatically tracks after the user delineates the target. At the same time, the device automatically checks whether the target is in the center of the screen, otherwise the device automatically rotates to keep the target in the center of the screen.

[0035] Second, the equipment adopts a...

Abstract

The invention relates to a traceable portable stereo live intelligent robot and a control method thereof. The functions of automatic face detecting and tracking, binocular camera three-dimensional imaging and real-time high-speed image transmission with a mobile device are realized. The method mainly comprises the steps that 1 a device integrates NMF face recognition based on alpha divergence, animproved tracking algorithm based on Kalman filter, an automatic calibration algorithm, a table lookup and anti-shake algorithm and the like to automatically or semi-automatically complete detection and track a face; 2 the device adopts a double-rudder parallel structure model and a control strategy thereof to cooperate with an automatic detection and face tracking algorithm to realize face tracking; and 3 the device simulates the eyes of a person to synchronously shoot two pictures, simultaneously plays two pictures according to the principle of parallax, and realizes stereoscopic live by means of VR glasses.

Description

technical field [0001] The invention belongs to the technical fields of image analysis, stereo photography and motion control, and in particular relates to a traceable portable stereo live broadcast intelligent robot and a control method thereof. Background technique [0002] With the rapid development of the webcast industry, the market has put forward higher requirements for the quality of live video. Currently, the shooting equipment for webcasting is mainly high-definition cameras, infrared cameras and mobile phones. Various devices are mostly clamped or hung on the ground and fixed in a certain position. It is necessary to manually move the camera position and adjust the focal length of the far and near scenes, which greatly affects the fluency of live video and the viewing experience of users. And almost all of them are monocular cameras, which cannot meet the needs of more and more users for the immersive experience of stereoscopic live broadcast. Contents of the i...
