Vehicle trajectory tracking test data production method, device, prediction and result test method

Abstract

The invention discloses a method for making vehicle trajectory tracking test data, which includes: defining desired vehicle trajectory parameters, including at least vehicle static parameters and vehicle dynamic parameters passing through each bayonet; The pictures that appear in different positions are used as the perspective picture of the vehicle passing through a bayonet; the close-up picture and the license plate picture of the vehicle are intercepted from the long-view picture; the format conversion of the close-up picture of the vehicle and the license plate picture is carried out to form picture data ; Send the passing data to the view library, the passing data at least consists of the bayonet ID, the device ID, the actual passing time, the distant view image, the close view image, the license plate image, the static parameters, the dynamic parameters and the picture data. The invention is used to solve the problem of data source for vehicle trajectory tracking test in actual engineering.

Description

technical field [0001] The present invention relates to the field of smart security, more specifically, to a method, device, prediction and result testing method for vehicle trajectory tracking test data in smart security. Background technique [0002] In the field of intelligent security, especially in intelligent transportation, vehicle trajectory tracking is a very important feature. Usually, the location data generated by vehicles passing through different bayonets forms the trajectory of the vehicle. The trajectory prediction needs to use the existing bayonet location data to calculate the future bayonet location, and then combine the original data to track. This business function is generally implemented by the application platform implementation. However, it is extremely inconvenient to test and verify this function in actual engineering. Because after the trajectory tracking starts, it is necessary to simulate the passing data of a certain bayonet device at a certa...

Problems solved by technology

However, this method requires someone to be on duty or to operate regularly, and each time the data is sent, it needs to be made and modified separately, and it is difficult to have regularity

These problems make R&D testers feel powerless in the face of testing and data collection in more complex trajectory tracking scenarios
