a vehicle-mounted device

Abstract

The embodiment of the invention discloses vehicle-mounted equipment. The vehicle-mounted equipment comprises an acquiring-converting device, a first image processing device, a second image processing device and a display, wherein the acquiring-converting device is used for processing acquired initial environmental data into target environmental data, and transmitting the target environmental data to the first image processing device; the first image processing device is used for acquiring a plurality of look-around data in the target environmental data, packaging the plurality of look-around data into a data packet to be processed, and transmitting the data packet to be processed to the second image processing device; the second image processing device is used for extracting the plurality of look-around data from the data packet to be processed, performing image splicing and image compression on the plurality of look-around data to obtain all-directional look-around video data, and displaying the all-directional look-around video data on the display; and the second image processing device has an image processing function and a video compression function. Through adoption of the vehicle-mounted equipment, the data processing function can be enriched, and the hardware design cost is lowered.

Description

technical field [0001] The invention relates to the field of computer application programs, in particular to a vehicle-mounted device. Background technique [0002] With the rapid development of science and technology, people's living standards have been rapidly improved. At present, more and more users tend to travel by self-driving, but the safety issues in self-driving travel usually become the focus of people's attention. Therefore, based on the high demand for car safety, most users tend to include the active emergency braking system into the scope of safety requirements when purchasing a car. In addition, according to a survey data from a Swiss company, for forward collisions, if the danger can be detected 2 seconds in advance and the driver is reminded, the probability of accidents will be reduced by more than 95%. And turning collision accidents can also be reduced to 10%. In view of this, cars equipped with ADAS (Advanced Driver Assistant Systems, Advanced Driver ...

Problems solved by technology

[0003] However, the existing ADAS solutions based on field programmable logic array FPGA only have the functions of ADAS forward anti-collision monitoring and early warning, lane detection early warning, lane departure early warning and pedestrian anti-collision early warning. forward binocular data and perform single image data processing on it

However, in the process of driving, there are often obstacles that suddenly appear around the vehicle. At this time, due to the limitation of the FPGA processing function, that is, there is no video codec function, and then the surround view data cannot be saved. In addition, the surround view data It will take up a lot of FPGA logic resources, which will seriously affect the hardware design cost of FPGA, and will seriously affect the data processing speed of ADAS system, so as to reduce system performance
