Abstract

The present application relates to the field of data processing, and in particular, to a method and apparatus for displaying a vehicle prompt line, an electronic device, and a storage medium. According to the method provided by the embodiment of the application, the distance change between the vehicle and the obstacle can be more intuitively displayed by analyzing the difference of the distance data and performing the action picture display, so that the problem of inaccurate distance grasping caused by jump is avoided. The distance between the obstacle and the vehicle is better judged by the driver, so that safer driving decisions are made. The curve segments are rendered according to the animation display strategy and connected with the curve segments rendered in different directions to form a complete continuous prompting line, so that the distance display is smoother, and jump caused by direction/distance change is avoided. The driver can more accurately sense the distance change between the vehicle and the obstacle, make more timely and accurate driving decisions, and improve driving safety.
