Abstract: The application discloses a method and an apparatus for reporting a traffic event, an electronic device and a storage medium. The detailed implementation scheme is: obtaining a surveillance video and an object in a surveillance video; obtaining location information and/or speed information of the object; determining whether the object occurs a traffic event based on the location information and/or the speed information of the object; in response to determining that the traffic event is occurred, reporting starting information of the traffic event and generating state information of the traffic event, in which the state information of the traffic event is updated with the location information and/or the speed information of the object; supervising the state information of the traffic event; reporting ending information of the traffic event in response to determining that the traffic event ends based on the state information of the traffic event.

Abstract: An event detection method and apparatus, a device, and a computer storage medium are provided, which are related to intelligent transportation and automatic driving. In a specific implementation, a target vehicle located in a target area is detected according to a surveillance video of the target area; acquisition time for the target vehicle and location information of the target vehicle in image frames corresponding to the acquisition time are determined; an acceleration of the target vehicle is obtained according to at least the acquisition time and the location information; and it is judged whether an emergency event occurs for the target vehicle according to the acceleration of the target vehicle. The acceleration of the target vehicle calculated by the embodiments of the present disclosure has a high accuracy, so that a more accurate judgment result can be obtained when subsequently judging whether an emergency event occurs for the target vehicle.

Abstract: A traffic light image processing method and device, a computer system, a roadside device, and a storage medium are provided. The method includes: acquiring image data of a traffic light from a roadside sensor, the image data of the traffic light including a sequence of image frames over time, and the traffic light including at least two light heads; performing difference processing on two temporally adjacent image frames to obtain a difference image, a pixel value of each pixel point of the difference image being equal to a difference value of corresponding pixel points of the two temporally adjacent image frames; performing thresholding processing on the difference image to obtain a thresholding processed difference image; and determining a switched-on light head in the traffic light based on the thresholding processed difference image.
