1. An electronic device comprising:
at least one processor; and
a storage device coupled to the at least one processor and storing instructions for execution by the at least one processor to cause the at least one processor to:
fuse obtained radar information and image information;
recognize at least one obstacle in a traveling direction of a vehicle according to the fused radar information and the image information;
determine motion parameters of the at least one obstacle and the vehicle according to the fused radar information and the image information; and
calculate a first collision countdown according to the motion parameters, the first collision countdown being proportional to a relative distance between the at least one obstacle and the vehicle and a predicted moving distance of the at least one obstacle and inversely proportional to a relative velocity between the at least one obstacle and the vehicle, calculate a braking distance of the vehicle according to a velocity of the vehicle and a gravitational acceleration, calculate a second collision countdown according to the motion parameters and the braking distance, the braking distance being proportional to a square of the velocity of the vehicle, and inversely proportional to a gravitational acceleration, the second collision countdown being proportional to the braking distance and inversely proportional to the relative velocity, and issue a collision warning when the first collision countdown is less than the second collision countdown.
