Image processing system and method applied to multi-path camera of large automobile

Abstract

The invention provides an image processing system and method applied to a multi-path camera of a large automobile, the system comprises the multi-path camera, an SoC processor and a display screen, and the multi-path camera and the display screen are connected with the SoC processor; wherein the SoC processor at least comprises a display controller, a second image processor, a video decoder and a view screen encoder, and the display controller, the second ISP image processor, the video decoder and the view screen encoder are mutually independent, are respectively connected to the AXI bus and exchange data through the AXI bus. Each sub-processing module of the processor SOC is independent, data interaction, video decoding, coding and video processing are independent through AXI bus connection, video input and output data streams can be processed in real time, and parallel processing of multi-channel video pipine is supported.

Description

technical field [0001] The invention relates to an image processing system of a multi-channel camera, in particular to an image processing system and method of a large-scale automobile multi-channel camera. Background technique [0002] In recent years, with the development and progress of technology, the current mainstream vehicle camera solutions basically transmit the video signal to the processing chip SOC through the video decoding chip through MIPI or parallel interface for processing. At present, in assisted driving cars, four cameras are generally used to form a surround view system to form a panoramic image, which can monitor the environment around the vehicle in real time, thereby reminding the driver to take measures. Due to the small length of the car or SUV itself, four cameras can be used to capture images around the car body. However, commercial vehicles, large trucks, trucks, etc. are too long due to their long bodies, such as figure 1 As shown in the figur...

AI Technical Summary

Problems solved by technology

However, commercial vehicles, large trucks, trucks, etc. are too long, such as figure 1 As shown, the traditional four-camera solution cannot form a surround-view system, and the number of cameras needs to be increased to more than six. Moreover, when the traditional LVDS traditional wiring harness distance increases, the image will suffer from problems such as blurring and EMC.
