Problems solved by technology

At present, most of the urban bus stop signs in China still stay in the original fixed form and function. The display content of the stop signs is too single. They only provide passengers with simple train numbers and driving routes. Passengers cannot know the specific information of vehicle operation, so that passengers can only Passive, bored waiting, unable to understand the real-time information of the vehicle
Long waiting time and poor experience are important reasons why citizens are unwilling to take buses, which seriously restricts the healthy development of urban public transportation systems

Embodiment 1

[0055] Bus real-time location information transmission process: First, the satellite positioning module installed on each bus obtains the real-time location information of the bus, and then transmits it to the back-end cloud server through the 4G / 5G communication module. The cloud server obtains the real-time location information of the bus on each relevant line and displays it on the interface.

[0056] Video summary enrichment process: first extract all frame images from the original video, and then select key frames in shot k

[0057]

[0058] in d(μ, μ+1) represents the distance of any type of visual description from frame μ to frame μ+1. From the measurement m, the keyframe t can first be calculated 1 , and then calculate t 2 ...finally it is possible to calculate Then, according to the compression rate α, α·N key frames are selected to form a video summary. For example: there is a video with a duration of 10 seconds and 25 frames per second, and the entire vi...
