System and method for dynamically adjusting frame rate of motion camera

Abstract

The invention discloses a system and a method for dynamically adjusting the frame rate of a motion camera. The system comprises an image acquisition module, a processing unit, a wireless communication module, a network condition detection module and a frame rate matching module which are integrated on the motion camera, and is characterized in that the image acquisition module is used for acquiring image data in real time according to a certain image acquisition frame rate; the processing unit is used for controlling the image acquisition frame rage of the image acquisition module; the wireless communication module is used for forwarding the image data acquired by the image acquisition module in real time through a wireless network; the network condition detection module is used for detecting the communication quality of the wireless network in real time and detecting the real-time effective transmission rate of the wireless network; and the frame rate matching module is used for dynamically adjusting the image acquisition frame rate according to the real-time effective transmission rate of the wireless network so as to enable the image acquisition frame rate to be synchronously matched with the real-time effective transmission rate of the wireless network. According to the invention, the acquisition frame rate of the image acquisition module can be adjusted according to user requirements or through feedback of network conditions, thereby enabling watch delay of viewers to be always consistent with acquisition delay of the motion camera.

Description

technical field [0001] The invention relates to the field of sports cameras, in particular to a system and method for dynamically adjusting the frame rate of a sports camera. Background technique [0002] In recent years, with the rapid development of network cameras, network cameras have gradually acted as people's "clairvoyance". However, most of the network camera equipment is connected to the network cable or is bulky, so the range and flexibility of the network camera are limited, resulting in a limited range of use. Most of them are used for shooting a scene in a fixed range, though. In this case, the application of "sports camera" was born. It is small in size and integrates a wireless communication module, which gets rid of the limitation of its activity range by network cables and volume. In this way, the "clairvoyance" can move. People who use sports cameras can wear it on their bodies, which is equivalent to their own eyes, and they can see wherever they go. An...

Problems solved by technology

[0003] Since the sports camera uses a wireless network for transmission, and the wireless signal will be unstable with the movement of the sports camera, this may cause the video data of the sports camera to be unable to transmit data in time due to poor network conditions, resulting in video data being in a state. The process of continuously accumulating and waiting for transmission, even when the network is in good condition, because a large amount of video data accumulated before has not been transmitted, the previous data will be transmitted first, and the currently collected video data will be delayed for transmission, so that The scene seen by the viewer has a large delay compared to the scene seen by the person wearing the action camera at that time
