Embodiment Construction
[0078] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0079] figure 1 It shows a cascaded control system of multi-stage camera equipment, which at least includes multiple camera equipment, video matrix and terminal. The camera device may be a device with an image collection function such as a video camera, and the terminal is specifically a video conference terminal.
[0080] see figure 1 , each camera device has two serial ports, one is COM-IN, the other is COM-OUT, COM-IN is used for inputting instructions, and COM-OUT is used for outputting instructions. The terminal is connected to the serial port COM-IN of the first camera device through the serial cable, and the serial port COM-OUT of the first camera device is connected to the COM-IN serial port of the second camera device, and s...

The invention discloses a method and device for controlling a camera shooting device, belonging to the multimedia technology field. The method comprises steps of transmitting an ID superposition instruction to a first stage camera device which is in direction connection; transmitting the ID superposition instruction from the first stage camera shooting device to a last stage camera shooting device stage-by-stage, wherein the ID superposition instruction is used for controlling each stage camera shooting device to superpose the ID of the camera shooting device on an appointed position area of an outputted image, successively returning ACK, obtaining a detection image when receiving an ACK returned by the last stage camera shooting device, searching a target image matched with the detection image from an image database which is established in advance, using an ID corresponding to the target image as a target ID, and controlling a camera shooting device corresponding to the target ID. The method and device for controlling camera shooting devices does not need to additionally arrange control devices, save control cost, does not need involvement of a user, can intelligently identify the camera shooting device to be controlled through receiving the superposed ID of the camera shooting device which is in the output image and improve control accuracy.
Description
technical field [0001] The invention relates to the field of multimedia technology, in particular to a method and device for controlling camera equipment. Background technique [0002] With the development of multimedia technology, video conferencing has become a high-frequency usage scenario in modern society. Users in different regions can interact and communicate in real time through video conferencing. The video conferencing system used in video conferencing usually includes a terminal and multiple camera devices, wherein each camera device is used to collect image data in the venue, and the terminal is used to establish a connection with the camera device through a serial port, and through the connected The camera device sends a control command to control the camera device. Due to the limited number of serial ports provided by the terminal, multiple camera devices cannot all establish connections with the terminal through the serial ports, making it impossible for the ...
