Assistance method of safe driving and electronic device

An electronic device comprising:

• a processor;
• and
• a non-transitory storage medium coupled to the processor and configured to store a plurality of instructions, which cause the processor to:
• in response that detecting a vehicle is in a driving state, obtain Red-Green-Blue (RGB) images of a scene in front of the vehicle;
• process the RGB images based on a trained depth estimation model, and obtain depth images corresponding to the RGB images;
• convert the depth images into three-dimensional (3D) point cloud maps;
• determine 3D regions of interest of the vehicle from the 3D point cloud maps according to a size of the vehicle;
• obtain position information and size information of objects in the 3D regions of interest;
• in response that the position information satisfies a first preset condition and/or the size information satisfies a second preset condition, determine that the 3D regions of interest have obstacles and that the objects are the obstacles, and control the vehicle to issue an alarm;
• and
• in response that the position information does not satisfy the first preset condition and/or the size information does not satisfy the second preset condition, determine that the 3D regions of interest have no obstacles, controlling the vehicle to continue driving.
