Title:
SCENARIO IDENTIFICATION-BASED VEHICLE ADAPTIVE SENSOR SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/253741
Kind Code:
A1
Abstract:
A scenario identification-based vehicle adaptive sensor system, comprising: an AVM around view sensor (1), an AVM around view controller (3), and an ADAS controller (5); the AVM around view sensor (1) includes a camera, a position adjustment mechanism (11), and a position sensor (12); the camera transmits collected image information to the AVM around view controller (3), the position adjustment mechanism (11) receives a position adjustment instruction of the AVM around view controller (3) and adjusts a position of the camera, and the position sensor provides feedback on the position of the camera to the AVM around view controller (3); and the AVM around view controller (3) transmits identified target information to the ADAS controller (5). The described system obtains an ROI region of interest adapted for a current vehicle operating scenario by means of scenario identification optimization, improving image processing performance of the system; within the AVM around view sensor (1), target identification is performed on an image, and output target and scenario information may be used by the ADAS controller (5), which can reduce the needed image processing chip capability of the ADAS controller (5), and can also reduce power consumption of an ADAS system, effectively reducing configuration costs.
