Embodiment Construction
[0017] Below, the present invention will be described in detail with reference to the accompanying drawings.
[0018] like figure 1 As shown, the present embodiment provides a multi-eye camera, including 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 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 through the data receiving end for processing.
[0019] Wherein, the main control chip controls the camera unit to be powered on at the same time. The main control chip is a 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 performance indicators of the image sensor are completely ...

The invention provides a multi-head camera and a frame synchronization method thereof. The multi-head camera comprises at least two image sensors and data sensing ends respectively corresponding to the image sensors, a power supply, a crystal oscillator, a data receiving end and a main control chip, wherein each image sensor and the corresponding data sending end form 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 to be processed. According to the multi-head camera provided by the invention, each camera unit shares a power supply and a crystal oscillator to effectively guarantee the synchronism of the working clock of each camera unit, so as to obtain a panoramic image with a good synchronous effect and overcome the problem in the background art that the frames of the multi-head camera are not synchronous, and the multi-head camera really realizes frame synchronization.
Description
technical field [0001] The invention relates to the technical field of multi-cameras, in particular to a multi-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. Driven by demand, multi-cameras are gradually appearing in the market. 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-eye camera contains 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...
