  • Method, device and system for processing startup of preceding vehicle
    Patent number: 10818172
    Abstract: A method, a device and a system for processing startup of a preceding vehicle, wherein, the method for processing startup of a preceding vehicle is applicable to the system for processing startup of a preceding vehicle, the system includes a video sensor and a gravity sensor. The method includes: collecting images in front of a vehicle head of a current vehicle by the video sensor and collecting acceleration information of the current vehicle by the gravity sensor (S102); determining a running state of the current vehicle based on image features in the images in front of the vehicle head and/or the acceleration information (S104); acquiring a movement path of a target object in the images in front of the vehicle head when the running state of the current vehicle is a stationary state (S106); determining whether to generate a reminder for reminding the current vehicle to startup based on the movement path of the target object (S108).
