Method and device for modifying background model of 3d svm in conjunction with distance sensor

A device for modifying a background model of a 3D surround view monitor (SVM) in conjunction with a distance sensor, the device comprising:

• one or more processors;
• and
• a memory storing instructions that, when executed by the one or more processors, cause the device to:
• receive distance information collected through an ultrasonic sensor;
• convert the received distance information from the ultrasonic sensor into two-dimensional coordinates using external parameters of the ultrasonic sensor;
• determine a shape of a bottom surface of a background model of a 3D SVM according to the two-dimensional coordinates;
• generate the background model of the 3D SVM based on the shape of the bottom surface;
• generate a vehicle model of the 3D SVM based on vehicle data and the background model of the 3D SVM;
• determine whether to activate a parking distance warning (PDW) function based on the received distance information from the ultrasonic sensor;
• generate a PDW graphic when the PDW function is activated;
• couple a 3D SVM screen with a PDW screen;
• and output the 3D SVM.
