Vehicle blind area obstacle warning method based on binocular camera and terminal

The invention provides a vehicle blind area obstacle warning method and terminal based on a binocular camera, and the method comprises the steps: calibrating the binocular camera disposed at the front end of a vehicle engine and at the vehicle blind area at the outer side of a vehicle door, and obtaining the internal parameters, external parameters and distortion parameters of the binocular camera; carrying out stereo matching on the binocular camera; training by using an image set acquired by the binocular camera based on a neural network algorithm to obtain an obstacle recognition model; and starting the binocular camera, shooting an image of a blind area of the vehicle in real time by adopting a monocular mode, transmitting the image shot in real time to the obstacle recognition model for obstacle recognition, and if an obstacle is recognized, obtaining an obstacle distance by adopting binocular measurement of the binocular camera, and displaying the obstacle distance in a vehicle-mounted display screen in
