Embodiment 1

[0054] The vehicle speed determination method provided by the present invention can be applied in a terminal, and the terminal can determine the vehicle speed through the vehicle speed determination method provided by the present invention. Terminals can be, but are not limited to, various computers, mobile phones, tablet computers, vehicle-mounted computers, and portable wearable devices.

[0055] Such as figure 1 Shown, in an embodiment of described vehicle speed determining method, comprise step:

[0056] S100. Acquire a target video, and acquire a pixel-level moving speed of the target vehicle between a first frame and a second frame in the target video.

[0057] The terminal executing the method for determining vehicle speed provided by this embodiment may be equipped with a camera, and the target video may be captured by the camera. The terminal may also be connected in communication with the camera. The transmission method is sent to the terminal. The target video is...

Embodiment 2

[0103] Based on the above embodiments, the present invention also provides a corresponding terminal, such as Figure 4 As shown, the terminal includes a processor 10 and a memory 20 . Understandably, Figure 4 Only some components of the terminal are shown, but it should be understood that implementation of all illustrated components is not required, and more or fewer components may be implemented instead.

[0104] The storage 20 may be an internal storage unit of the terminal in some embodiments, such as a hard disk or memory of the terminal. In other embodiments, the memory 20 may also be an external storage device of the terminal, such as a plug-in hard disk equipped on the terminal, a smart memory card (Smart Media Card, SMC), a secure digital (Secure Digital, SD ) card, flash memory card (Flash Card), etc. Further, the memory 20 may also include both an internal storage unit of the terminal and an external storage device. The memory 20 is used to store application sof...

Embodiment 3

[0107] The present invention also provides a storage medium, wherein one or more programs are stored, and the one or more programs can be executed by one or more processors, so as to realize the steps of the method for determining the vehicle speed as described above.

Abstract

The invention discloses a vehicle speed determination method, a terminal and a storage medium. The method comprises the steps of: obtaining a target video, and obtaining the pixel-level moving speed of a target vehicle between a first frame and a second frame in the target video; obtaining a scaling factor according to the reference object pixel distance and the reference object real distance in the target video, the scaling factor reflecting a proportional relation between the pixel distance and the real distance in the target video; and determining the driving speed of the target vehicle according to the pixel-level moving speed and the scaling factor. The method can achieve the speed measurement of a plurality of vehicles at a time, and meets the speed measurement demands of a complex traffic environment.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a method for determining vehicle speed, a terminal and a storage medium. Background technique [0002] Vehicle speed detection is used to judge whether the vehicle is speeding and reduce the frequency of traffic accidents. In the prior art, there are many detection methods for the vehicle speed. Currently, the more common speed measurement method is radar speed measurement. Radar speed measurement uses the Doppler effect to measure speed, but radar speed measurement cannot realize the speed measurement of multiple vehicles at one time, and cannot meet the speed measurement requirements in complex traffic environments. [0003] Therefore, the prior art still needs to be improved and improved. Contents of the invention [0004] In view of the above defects of the prior art, the present invention provides a vehicle speed determination method, a terminal and a storage med...
