Embodiment Construction

[0049] In order to have a clearer understanding of the technical features, purposes and effects herein, the specific embodiments of the present invention will now be described with reference to the accompanying drawings, in which the same reference numerals denote the same parts. For the sake of brevity of the drawings, the relevant parts of the present invention are schematically shown in each drawing, and do not represent the actual structure as a product. In addition, in order to make the drawings simple and easy to understand, in some drawings, only one of the components having the same structure or function is schematically shown, or only one of them is marked.

[0050]With regard to the control system, functional modules and application programs (APP) are well known to those skilled in the art, and can take any appropriate form, either hardware or software, a plurality of discretely set functional modules, or are multiple functional units integrated into one hardware. I...

Abstract

The invention provides a vehicle-mounted Ethernet surround view system with ESD interference resistance, which at least comprises an intelligent host, a plurality of vehicle-mounted Ethernet cameras and a TSN gateway, the vehicle-mounted Ethernet cameras are connected with the TSN gateway through a vehicle-mounted Ethernet bus, and the intelligent host is connected with the TSN gateway through the vehicle-mounted Ethernet bus; a plurality of vehicle-mounted Ethernet cameras collect images around a vehicle body and send the images to an intelligent host through a TSN gateway, the intelligent host calls an image splicing algorithm to splice the images to form a panoramic image and sends the panoramic image to a display screen, meanwhile, the structures of the vehicle-mounted Ethernet cameras are changed, and through design of metal pieces, the panoramic image is obtained. The lens is connected with the lens body, the PCBA circuit board and the shell, so that static electricity can be quickly conducted away. In the panoramic image splicing process, the overlapping area does not need to be selected by a feature point matching method adopted in the prior art, but high-speed registration splicing is carried out according to the pixel coordinates for obtaining the overlapping area, so that the real-time performance is realized.

Description

technical field [0001] The invention relates to a vehicle-mounted Ethernet surround view system, in particular to a vehicle-mounted Ethernet surround view system with anti-ESD interference. Background technique [0002] In recent years, with the development and progress of technology, the continuous improvement of automobile technology has been promoted. Assisted driving, automatic driving, and unmanned driving have pushed the automobile bus towards high speed and low latency. Therefore, the vehicle Ethernet bus has become an inevitable choice for automobile communication technology. . At this stage, the in-vehicle Ethernet surround view system is mainly installed in passenger cars, and uses LVDS bus technology for image transmission. However, the wiring harness supporting LVDS communication needs to be shielded, so as the communication distance increases, the cost of the wiring harness will increase rapidly. And in the case of large trucks and heavy trucks, due to the lon...
