A method for processing startup of a preceding vehicle, wherein the method is applicable in a system for processing startup of a preceding vehicle, the system comprises a video sensor and a gravity sensor, the method comprises: 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; 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; acquiring a movement path of one or more target objects in the images in front of the vehicle head when the running state of the current vehicle is a stationary state; and determining whether to generate a reminder for reminding the current vehicle to startup based on the movement path of the one or more target objects; wherein, 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 comprises: determining whether the running state of the current vehicle is a stationary state or a moving state based on frame difference foreground ratios of N successive frames of images in front of the vehicle head and/or the acceleration information of the current vehicle when the running state of the current vehicle is an initial state, wherein the initial state is a state set by the system for the current vehicle when the system is started; determining whether the running state of the current vehicle is the stationary state or the moving state based on frame difference foreground ratios and/or frame difference foreground dispersions of N successive frames of images in front of the vehicle head, and in combination with the acceleration information of the current vehicle when the running state of the current vehicle is not the initial state; wherein, the image features in the images in front of the vehicle head comprise the frame difference foreground ratios and the frame difference foreground dispersion. 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; 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; acquiring a movement path of one or more target objects in the images in front of the vehicle head when the running state of the current vehicle is a stationary state; and determining whether to generate a reminder for reminding the current vehicle to startup based on the movement path of the one or more target objects; wherein, 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 comprises: determining whether the running state of the current vehicle is a stationary state or a moving state based on frame difference foreground ratios of N successive frames of images in front of the vehicle head and/or the acceleration information of the current vehicle when the running state of the current vehicle is an initial state, wherein the initial state is a state set by the system for the current vehicle when the system is started; determining whether the running state of the current vehicle is the stationary state or the moving state based on frame difference foreground ratios and/or frame difference foreground dispersions of N successive frames of images in front of the vehicle head, and in combination with the acceleration information of the current vehicle when the running state of the current vehicle is not the initial state; wherein, the image features in the images in front of the vehicle head comprise the frame difference foreground ratios and the frame difference foreground dispersion. determining whether the running state of the current vehicle is a stationary state or a moving state based on frame difference foreground ratios of N successive frames of images in front of the vehicle head and/or the acceleration information of the current vehicle when the running state of the current vehicle is an initial state, wherein the initial state is a state set by the system for the current vehicle when the system is started; determining whether the running state of the current vehicle is the stationary state or the moving state based on frame difference foreground ratios and/or frame difference foreground dispersions of N successive frames of images in front of the vehicle head, and in combination with the acceleration information of the current vehicle when the running state of the current vehicle is not the initial state; wherein, the image features in the images in front of the vehicle head comprise the frame difference foreground ratios and the frame difference foreground dispersion.
