Preceding vehicle detection method, and training acquisition method and device of preceding vehicle detection model

The invention provides a preceding vehicle detection method, and a training acquisition method and device of a preceding vehicle detection model. The preceding vehicle detection method comprises the steps of acquiring a target image of a forward view of a current vehicle; inputting the target image into a preceding vehicle detection model obtained by pre-training to obtain preceding vehicle information output by the preceding vehicle detection model, the preceding vehicle information including whether there is a preceding vehicle, the distance between the vertex of the preceding vehicle and each preset anchor point in the direction in each direction, and the distance between the vanishing point of the front vehicle and each preset anchor point in the direction where the vanishing point islocated; and if the front vehicle exists, determining the vertex coordinate of the front vehicle according to the distance between the vertex of the front vehicle and each preset anchor point in the direction in each directio
