Method and system of population flow statistics based on intelligent video identification technology

Abstract

The invention provides a method and a system of population flow statistics based on an intelligent video identification technology. The method comprises the following steps: obtaining a human body template in a current frame video image by scanning according to information in a database for a standard human body template; judging whether the advancing direction of the obtained human body template faces to a first direction or a second direction, increasing the count of the first direction by 1 when judging the advancing direction of the human body template faces to the first direction, increasing the count of the second direction by 1 when judging the advancing direction of the human body template faces to the second direction. The invention can accurately monitor the population coming and going in the channel through the steps by statistics, can not cause the statistical error due to larger staff flow, and can also damage the ground, thereby lowering the monitoring cost.

Description

technical field [0001] The invention relates to a method and system for counting people flow, and in particular to a method and system for counting people flow based on intelligent video recognition technology. Background technique [0002] In today's society, the city is developing very rapidly, the population of the city is growing rapidly, and the flow of people is increasing day by day. The problem of the flow of people has become a major problem in urban management, especially in important public places. It is necessary to monitor the flow of people. Therefore, it is necessary to The flow of people is counted in real time, and judgments are made based on the obtained data to decide whether guidance is required. [0003] In many exhibitions, shopping malls and other public places, in order to control and understand the number of visitors, counters are usually installed at the passages. At present, there are two kinds of counters: infrared type and mechanical type. Infra...

Problems solved by technology

At present, there are two kinds of counters: infrared type and mechanical type. Infrared type counters use infrared sensors to sense the passing people to count and count. The type counter needs to bury the induction pedal under the channel. When the personnel step on the pedal, the counter is touched to perform personnel technical statistics. Similarly, this method is not accurate in counting when the flow of people is relatively large, and has a large error, and needs to be in the channel. Buried pedals under the ground also increase the cost, and both infrared and mechanical counters generally use the accumulative method, so they can only count the total number of people in one direction, but not the number of people traveling in both directions, so they cannot be based on the data of the number of people coming and going make bootstrap adjustments
