Embodiment 1

[0071] figure 1 It is a flow chart of a smart car door opening method provided by Embodiment 1 of the present invention. This embodiment is applicable to the situation where a smart car opens the door safely and conveniently. This method can be executed by the smart car door opening device provided by the embodiment of the present invention. The device can be implemented by software and / or hardware, and is usually configured in a smart car, such as figure 1 As shown, the method specifically includes the following steps:

[0072] S101. Acquire a captured image captured by a vehicle-mounted TOF camera.

[0073] Specifically, the TOF (Time of Flight, time of flight) camera emits modulated near-infrared light, which is reflected by the object and received by the camera. By calculating the time difference or phase difference between light emission and reflection, and collecting the data, a group of Distance depth data to get a 3D image. The TOF camera has the advantages of long-...

Abstract

The invention discloses an intelligent automobile door opening method and device, an intelligent automobile and a storage medium. The method comprises the steps of obtaining a shot image collected bya vehicle-mounted TOF camera; extracting a region image including a human face from the shot image; extracting human face features from the region image; and opening a vehicle door of the intelligentautomobile when the human face features are matched with preset face features of an automobile owner. The user can unlock the vehicle door without manual operation, so that the convenience is improved. Besides, the TOF camera is adopted to acquire images so that the method can better adapt to the weak light environment, the identification distance can be enhanced, the identification precision canbe enhanced and the response time can be shortened. The face features of the automobile owner are stored locally in the intelligent automobile, communication with a remote server is not needed in theface detection and recognition process, the problem that automobile owner information is leaked due to the fact that the automobile owner information is cracked in the data transmission process is avoided, and the safety of user information is guaranteed; meanwhile, communication with a server is not needed, so that the unlocking speed is increased.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of smart cars, and in particular, to a method and device for opening a door of a smart car, a smart car and a storage medium. Background technique [0002] With the continuous development of smart car technology, users are paying more and more attention to car safety, and there is a great demand for the convenience of smart cars. Therefore, it is an inevitable trend to realize convenient and safe functions through innovative technologies such as cameras and face recognition. . [0003] At present, the unlocking and opening of the car is mainly through remote unlocking and keyless entry. The remote unlocking and opening of the door requires manual opening of the door, and the car door cannot be opened when hands are inconvenient, which causes great inconvenience to the user. Although keyless entry is relatively convenient, its security is poor and it is easy to be cracked. Conten...
