PANORAMIC LOOK-AROUND VIEW GENERATION METHOD, IN-VEHICLE DEVICE AND IN-VEHICLE SYSTEM

The current disclosure relates to a panoramic look-around view generation method, an in-vehicle device and an in-vehicle system. The method comprises the following steps of: acquiring images of areas around a vehicle, steering wheel angle information and vehicle speed information; transforming and mosaicking the images to generate a time-related look-around view, and using an ORB algorithm to extract characteristic points; using steering wheel angle information and vehicle speed information to calculate a positron of a characteristic point of the look-around view at previous time in the look-around view at current time according to a vehicle motion model, and selecting a characteristic point located near the position in the look-around view at current time to be matched with the characteristic point of the look-around view at previous time; calculating an affine transformation matrix and performing affine transformation, and performing weighted fusion with the look-around view at current time and storing it; repeating the above steps to obtain a continuously updated panoramic look-around view, The method, the device and the system can eliminate blind area in the underbody region, realize a panoramic perspective view, and have fast calculation and high accuracy.
