[0237] Scenario Example 2: Autonomous Driving System

[0238] according to figure 2 , the computer system 101 includes a processor 103 coupled to a system bus 105 . The processor 103 may be one or more processors, each of which may include one or more processor cores. A video adapter (video adapter) 107 can drive a display 109 , and the display 109 is coupled to the system bus 105 . The system bus 105 is coupled to an input-output (I / O) bus 113 through a bus bridge 111 . The I / O interface 115 is coupled to the I / O bus. The I / O interface 115 communicates with various I / O devices, such as an input device 117 (eg, keyboard, mouse, touch screen, etc.), a multimedia tray (media tray) 121, (eg, CD-ROM, multimedia interface, etc.). Transceiver 123 (which can send and / or receive radio communication signals), camera 155 (which can capture landscape and dynamic digital video images) and external USB interface 125 . Wherein, optionally, the interface connected to the I / O interface ...

[0265] Computer system 112 may also receive information from, or transfer information to, other computer systems. Alternatively, sensor data collected from the sensor system 104 of the vehicle 100 may be transferred to another computer for processing of this data. Such as Figure 4 As shown, data from computer system 112 may be transmitted via a network to cloud-side computer 720 for further processing. Networks and intermediate nodes may include a variety of configurations and protocols, including the Internet, World Wide Web, Intranets, Virtual Private Networks, Wide Area Networks, Local Area Networks, private networks using one or more of the company's proprietary communication protocols, Ethernet, WiFi, and HTTP, and various combinations of the foregoing. Such communications may be by any device capable of transmitting data to and from other computers, such as modems and wireless interfaces.

[0266] In one example, computer 720 may include a server having multiple comp...

Abstract

The invention discloses an automatic driving technology in the field of artificial intelligence, and particularly relates to a road drivable area reasoning method. The method comprises the following steps of acquiring a perceptual drivable area; verifying the perceived drivable area to obtain a first area and a second area; if the first area does not cover the ROI, reasoning the second area according to the drivable area perception memory information to obtain a third area and a fourth area; if the first region and the third region do not cover the ROI, reasoning a fourth region according to the drivable position point to obtain a fifth region; and determining the first area, the third area and the fifth area as road drivable areas. The invention further discloses a road drivable area reasoning device. By adopting the method, the accurate road drivable area can be obtained when the road drivable area sensing result is abnormal, and safety, system availability and user experience of theautomatic driving system are further improved.

Description

technical field [0001] The invention relates to the field of equipment artificial intelligence, in particular to a method and device for inferring road drivable areas in intelligent assisted driving or automatic driving technology. Background technique [0002] Artificial Intelligence (AI) is a theory, method, technology and application system that uses digital computers or machines controlled by digital computers to simulate, extend and expand human intelligence, perceive the environment, acquire knowledge and use knowledge to obtain the best results. In other words, artificial intelligence is the branch of computer science that attempts to understand the nature of intelligence and produce a new class of intelligent machines that respond in ways similar to human intelligence. Artificial intelligence is to study the design principles and implementation methods of various intelligent machines, so that the machines have the functions of perception, reasoning and decision-makin...
