Description
Technical field:
The present invention relates to a kind of stream of people's analytical equipment, particularly a kind of building on public transport or long-distance bus can be to the terminal of vehicle, stand a hinge guest flow statistics and analysis.
Background technology:
As everyone knows, in public places, as, in mass transportation facilities and supermarket, place such as exhibition need add up the number of turnover, in above-mentioned place number added up accurately to be very important.Especially on mass transportation facilities, based on China's national situation, it is all more crowded generally to get on or off the bus, and same car door can have the passenger who gets on or off the bus simultaneously, is necessary very much to add up.If adopt complicate statistics, its work capacity and difficulty are big can be imagined, statistics is got up difficult especially.Along with the enforcement of ITS (intelligent transportation system), to the stronger demand of having of passenger flow statistics.In the case, press for that a kind of energy is unartificial, high-accuracy, be fit to the appearance of the passenger flow statistical system of mass transportation facilities environment.
Unartificial quantity statistics also is very difficult thing.Present existing passenger flow statistics is used the simple scenario that often can only carry out unidirectional statistics, disposable.That is the people of, can only be to a direction and getting on the bus or getting off, being added up can only sequencedly count.These passenger flow statisticses mainly come passenger flow is carried out demographics in the following ways: 1, the infrared ray of distich (active), 2, extreme infrared (passive type), 3, super sonic, 4, the passive type soft-touch control.Above-mentioned several modes for folk prescription to, single and have the situation of certain intervals, certain statistical accuracy is arranged.Its shortcoming except be subject to ambient interference, statistical error big, go up or get off for two-way, many people, perhaps during the situation of passenger flow relatively more crowded (anyone is little at interval), the accuracy rate of its statistics/counting will descend greatly, can't work basically.But the situation of reality is often to have several people to get on the bus at the same time or get off.When more having very, employing along with novel mass transportation facilities, the preceding mode of getting on the bus that goes up under the back also will gradually reduce, concerning a winnowing machine door, demand side is got on the bus simultaneously and is got off several people are arranged, for the people stream counting of this complicated state, existing mass transportation facilities counting mode then is at a loss what to do.
Summary of the invention:
The present invention is directed to above-mentioned existing stream of people's statistical technique existing problem on mass transportation facilities, build on public transport or long-distance bus and provide a kind of, can be to vehicle, stand a hinge guest flow statistics and analysis, for making rational planning for of city bus engaged line scheduling provides reference frame, and the device of the dynamic passenger flow analysing of a vehicle-mounted video of cover that overload is monitored in real time to long-distance bus that can be effective.
