Embodiment Construction
[0017] Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
[0018] like figure 1 As shown in the figure, this embodiment provides a multi-camera camera, which includes at least two image sensors and their corresponding data sending ends, a power supply, a crystal oscillator, a data receiving end and a main control chip, each image sensor The corresponding data sending end is a camera unit, each camera unit shares a power supply and a crystal oscillator, and the camera unit sends the collected image data to the main control chip for processing through the data receiving end.
[0019] The main control chip controls the camera unit to be powered on at the same time. The main control chip is Hi3531 chip.
[0020] Specifically, in this embodiment, image sensors of the same manufacturer and the same model and specification are used. Although it is still difficult to ensure that the image sensor performance indicators are co...

The invention provides a multi-eye camera and a frame synchronization method thereof, wherein the multi-eye camera includes at least two image sensors and corresponding data sending ends, a power supply, a crystal oscillator, a data receiving end and a main control Chip, each image sensor and its corresponding data sending end is a camera unit, each camera unit shares a power supply and a crystal oscillator, and the camera unit sends the collected image data to the main control chip through the data receiving end for processing. The multi-eye camera of the present invention effectively ensures the synchronization of the working clock of each camera unit by sharing a power supply and a crystal oscillator for each camera unit, so as to obtain a panoramic image with good synchronization effect, which overcomes the multi-eye camera described in the background technology. The problem of camera frame asynchrony makes the multi-camera achieve real frame synchronization.
Description
technical field [0001] The invention relates to the technical field of multi-eye cameras, in particular to a multi-eye camera and a frame synchronization method thereof. Background technique [0002] With the continuous advancement of video technology, video applications are becoming more and more extensive, and people's requirements for video are getting higher and higher. Multi-cameras are also emerging in the market driven by demand. The so-called multi-eye camera is a device that uses multiple image sensors at the front end and uses image processing technology at the back end to combine the images of multiple image sensors into a complete image. [0003] The current multi-camera includes multiple image sensors, each sensor corresponds to an independent encoding chip, the encoding chip independently encodes the video collected by the image sensor, and then sends the encoded data to the network through the network, and the host on the network uses the image Stitching tec...
