Specific embodiment
First embodiment
Referring to Figure 1, Fig. 1 shows the process signal of the pedestrian track acquisition methods of the application first embodiment offer
Figure, specifically comprises the following steps:
Step S110 obtains track identification result data, wherein the track identification result data includes pedestrian ID, knows
Other time and pedestrian's coordinate point, the same camera of track identification result data obtain in the first preset time period
The multiple pictures of the corresponding pedestrian of the pedestrian ID.
Track identification result data may include pedestrian ID, recognition time and pedestrian's coordinate point, and pedestrian ID can be mark
Know the pedestrian, be allowed to the identifier distinguished with other pedestrians, specifically, camera can according to the apparel characteristic of pedestrian come
Generate pedestrian ID.Recognition time can be the exact date of camera shooting, also may include that camera occurs from record pedestrian
The specific duration to disappear from the visual field of camera to the pedestrian.Pedestrian's coordinate point can be the corresponding pedestrian of pedestrian ID in image
In the coordinate at four angles that outlines of rectangle frame.
The track identification result data is specially the pedestrian that same camera obtains in the first preset time period
The multiple pictures of the corresponding pedestrian of ID.
Before step S110, the method also includes: obtain the video flowing of camera acquisition；Control graphics processor pair
The video flowing is handled, and the track identification result data is obtained.
Specifically, the video flowing in the camera coverage can be collected by camera, and by video stream
Graphics processor processing is given, to obtain track identification result data.Graphics processor can be pre-processed, including check number
According to correctness and compressed data, then pretreated data are bundled in message queue, data are read from message queue, together
When to the data decompression and arrangement taken out.
Graphics processor during processing, can generate pedestrian ID according to the garment feature of pedestrian, and by the row
The corresponding pedestrian of people ID is outlined in a manner of rectangle frame in the picture, then can also provide four angles of rectangle frame, the i.e. square
The coordinate points of shape frame.
Step S120 obtains corresponding multiple pictures per second in first preset time period, to described per second corresponding
The pedestrian's coordinate point of the pedestrian ID of multiple pictures is averaged, and corresponding pedestrian ID per second in first preset time period is obtained
Pedestrian position average value.
First preset time period is that the corresponding pedestrian of pedestrian ID occurs disappearing to the pedestrian from the picture that camera takes
The period in picture is lost, camera is per second can to shoot multiple pictures.
For the multiple pictures of acquisition per second, it can average, obtain to the corresponding pedestrian's coordinate point of pedestrian ID in photo
Obtain pedestrian position average value.Specifically, the interposition on rectangle frame bottom edge can be obtained according to the corresponding rectangle frame of pedestrian's coordinate point
It sets, as the location point of pedestrian, then specifically averages to pedestrian location point, obtain pedestrian position average value.
In a kind of specific embodiment, the first preset time period can be 10 seconds, and camera is per second can to obtain 5
Photo all obtains the average value of the location point of pedestrian in 5 photos then for each second in 10 seconds, to obtain in 10 seconds
The pedestrian position average value of corresponding pedestrian ID per second.
Step S130 calculates the position difference of adjacent two seconds pedestrian position average value in first preset time period.
After the pedestrian position average value for obtaining corresponding pedestrian ID per second, the phase in the first preset time period can be calculated
The position difference of adjacent two seconds pedestrian position average value.
Step S140, judges whether the position difference is greater than the first preset value, if so, executing step S150.
Then the position difference of adjacent two seconds pedestrian position average value is compared with the first preset value, if alternate position spike
Value is greater than the first preset value, then shows that pedestrian is in moving condition, therefore execute step S150.
Step S150 determines that the corresponding pedestrian of the pedestrian ID is in movement in above-mentioned adjacent two seconds.
Determine that the corresponding pedestrian of pedestrian ID in above-mentioned adjacent two seconds is in moving condition.
Fig. 2 is referred to, Fig. 2 shows a kind of specific realities for the pedestrian track acquisition methods that the application first embodiment provides
Mode is applied, is specifically comprised the following steps:
Step S110 obtains track identification result data, wherein the track identification result data includes pedestrian ID, knows
Other time and pedestrian's coordinate point, the same camera of track identification result data obtain in the first preset time period
The multiple pictures of the corresponding pedestrian of the pedestrian ID.
Step S120 obtains corresponding multiple pictures per second in first preset time period, to described per second corresponding
The pedestrian's coordinate point of the pedestrian ID of multiple pictures is averaged, and corresponding pedestrian ID per second in first preset time period is obtained
Pedestrian position average value.
Step S130 calculates the position difference of adjacent two seconds pedestrian position average value in first preset time period.
Step S140, judges whether the position difference is greater than the first preset value, if so, executing step S150；If it is not, holding
Row step S160.
Step S150 determines that the corresponding pedestrian of the pedestrian ID is in movement in above-mentioned adjacent two seconds.
Step S160 determines that the corresponding pedestrian of the pedestrian ID is stationary state in above-mentioned adjacent two seconds.
The position difference of adjacent two seconds pedestrian position average value is compared with the first preset value, if position difference is small
In the first preset value, then show that pedestrian almost without movement, then can be determined that the corresponding row of pedestrian ID in above-mentioned adjacent two seconds
Man-made static's state.
Fig. 3 is referred to, Fig. 3 shows the specific steps schematic diagram after step S160, specifically comprises the following steps:
Step S170 connects the pedestrian position average value according to the time sequencing of first preset time period
Line obtains the corresponding pedestrian track of the pedestrian ID.
Line can be carried out to the pedestrian position average value of acquisition according to the time sequencing of the first preset time period, thus
The corresponding pedestrian track of pedestrian ID is obtained, location point when wherein pedestrian is stationary state can also be averaged again, to obtain
Obtain the position of the corresponding pedestrian track of pedestrian ID.
The pedestrian track is generated corresponding data according to GeoJSON standard by step S180.
Specifically pedestrian track can be generated into corresponding data according to GeoJSON standard.
The data are integrated and are stored to service database by step S190.
Then it will store after these above-mentioned Data Integrations into service database.
Specifically, due to there is multiple brand quotient in market, each brand quotient has multiple shops, and there are multiple camera shootings in each shops
Head, thus can according to the sequence of brand quotient ID, shops ID, camera ID and pedestrian ID come to track identification result data into
Row classification.
Due to being classified to track identification result data, data analysis condition can be constructed to inquire after classification
Track identification result data constructs query statement according to data analysis condition, thus the track identification number of results completed to classification
According to being inquired.Inquiry operation request specifically can be to time series database initiation.According to the corresponding camera of inquiry request
ID and pedestrian ID, can obtain the movement track that the pedestrian ID is obtained under the shooting of camera ID, and according to
GeoJSON standard criterion generates corresponding data.It, can be by data according to certain after data are reintegrated and classified
Rule is saved in database, which can be service database.
