Abstract

The invention discloses a method and a system for realizing video acquisition, encoding and transmission of a vehicle-mounted camera, and relates to the technical field of video processing. Aiming atthe problems of overlarge volume and incapability of realizing wireless transmission of a built-in form and a built-out form of traditional camera video acquisition and encoding, the technical schemeis adopted based on a vehicle-mounted camera module, a video acquisition module and a main control module in an onboard surface mounting form, and the realization process comprises the following steps: the vehicle-mounted camera module is started, and naked video data is output in real time by the vehicle-mounted camera module; the video acquisition module acquires naked video data in real time and transmits the naked video data to the main control module in real time through a PCIE interface, wherein the main control module comprises a video processing sub-module and a video encoding sub-module, the video encoding sub-module encodes bare video data in real time, and the video processing sub-module compresses the encoded bare video data in real time and transmits the encoded bare video data to the cloud server in a wireless mode. The system is small in size and high in code transmission reliability, and can be widely applied to unmanned vehicles.

Description

technical field [0001] The invention relates to the technical field of video transmission, in particular to a method and system for realizing video acquisition, encoding and transmission of a vehicle-mounted camera. Background technique [0002] Traditional camera video capture and encoding are divided into two forms: in-camera and out-of-camera. In-camera capture and encoding are limited to equipment performance issues, and generally have a large delay, which cannot meet real-time requirements. The out-of-camera form is generally In the form of a traditional server plus an acquisition card and an encoding card, the volume is large, the power consumption is high, and the reliability is low, which cannot meet the needs of vehicle use, and the above two methods cannot realize wireless transmission. Contents of the invention [0003] Aiming at the problem that the traditional camera video collection and coding methods, the internal and external forms are too large and wireles...
