[0055] S100: obtaining a preset target image, a vehicle surrounding environment image, a vehicle external environment parameter, and a user demand instruction.

[0056] In the embodiments of the present application, obtaining a preset target image includes obtaining an image of a preset target person, and the preset target person includes a driver himself or a passenger to be entered into the vehicle. Alternatively, the preset target image can be an image containing the biological features of the driver or the passenger to be entered into the vehicle, such as a face image or an overall image containing a face. The preset target image can be image information pre-imported into the telescopic device control system, or sent to the control system by a user terminal controlling the telescopic device. Specifically, when the telescopic device is automatically opened, the image information of the driver himself or the passenger to be entered into the vehicle needs to be obtained first, the vehicle surrounding environment image is obtained by the vehicle-mounted data acquisition sensor, and then the image of the object to be identified obtained from the vehicle surrounding environment image is sent to the telescopic device control system for processing and compared with the preset target image in the system, so that the control system can determine the target object in the vehicle surrounding environment image and further obtain the position of the target object.

[0057] S200: determining a target object according to the preset target image and the vehicle surrounding environment image;

[0058] In the embodiments, after obtaining the preset target image, the image features of the preset target image are obtained by performing feature recognition on the preset target image, the image features of the image to be identified are obtained by performing feature recognition on the image to be identified, and when the matching degree of the image features of the preset target image and the image features of the image to be identified is greater than a preset matching degree threshold, the target object is determined.

[0059] Specifically, the feature recognition on the preset target image and the image of the object to be recognized includes extracting the facial features in the image, obtaining features including facial geometric features, contours or three-dimensional data, etc. The extracted image features of the preset target image and the image features of the object to be recognized are searched and compared according to a certain coordinate rule or a certain order. When the matching degree of the image features of the preset target image and the image features of the object to be recognized is greater than a preset matching degree threshold, the target object is determined. In this embodiment, when the preset target image and the image of the object to be recognized are both facial images, the contour features of the face, the shape of the facial organs, and the geometric features such as the distance between them are extracted, and the facial features obtained according to the preset target image are compared with the facial features of the object to be recognized. When the matching degree is greater than or equal to 85%, it is determined that the image of the object to be recognized is the target object. Specifically, the preset matching degree threshold is greater than or equal to 85%. Preferably, it can be 85%, 90%, 95%, etc. The higher the preset matching degree threshold is set, the higher the accuracy of determining the target object according to the image feature recognition is.

[0061] Specifically, the determination of the position parameter of the target object relative to the vehicle includes positioning the target object by using Wi-Fi positioning, Bluetooth positioning or ultra-wideband positioning, and determining the position parameter of the target object relative to the vehicle.

[0062] Specifically, for a user carrying a user terminal or a mobile terminal integrated with Bluetooth function, as long as the Bluetooth function of the user terminal is turned on, the control system of the telescopic device can determine the position of the target object through the Bluetooth positioning function. The ultra-wideband positioning technology is a wireless technology based on extremely narrow pulses with high transmission rate, low transmission power, strong penetration ability and no carrier.

In some embodiments, the position of the target object can also be determined by using GPS, infrared positioning or ultrasonic positioning technology.

[0072] Specifically, in some embodiments, the staying time of the target object outside the vehicle can also be acquired. When the light parameter in the environment outside the vehicle is greater than or equal to a first preset light intensity threshold, the temperature parameter is greater than or equal to a preset temperature parameter, the distance between the target object and the vehicle is less than or equal to a preset distance threshold, and the staying time of the target object outside the vehicle is greater than a preset staying time, the retractable device is controlled to be deployed.

[0080] Specifically, when the vehicle is in a stationary state, the light intensity sensor acquires that the light parameter in the environment outside the vehicle is greater than or equal to a second preset light intensity threshold, the retractable device can be controlled to be deployed, and the solar photovoltaic panel on the retractable device converts light energy into electric energy and stores it in the storage battery. The second preset light intensity threshold can be set to the minimum light intensity value that can enable the solar photovoltaic panel to convert solar energy into electric energy.

[0081] Specifically, the battery of the telescopic device can supply power to the on-board power supply according to the user's demand.
