All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The embodiment of the invention discloses a method for generating a dot matrix diagram of a hot spot area, which is shown in a figure 1 and comprises the following steps:
s11: a bitmap is received.
Specifically, the receiving management system side uses an interface/sethotspot cfg for configuring the hotspot area, and the parameters are as follows: zoomural = bitmap sent from URL address of bitmap and saved.
Specifically, the bitmap may be generated in advance by the management system, and the device, such as a camera, may directly receive the produced bitmap for subsequent processing.
S12: and recording the entering time and the leaving time of each target object in each area in the dot-matrix diagram by using the time record file.
Specifically, using the time recording file, the file naming format may be: z _ mac _ date _ time _ h, records the entry time of each target object into the entry area in each area, and the exit time of the exit area. The format of the record may be: [ peoples ID ] [ ZoomaD ] [ InTime ] [ OutTime-InTime ], see Table 1, where [ peoples ID ] is used to distinguish different people in an image, [ ZoomaD ] is used to record the area that a target object enters, [ InTime ] is used to record the time that the target object enters the area, and [ OutTime-InTime ] is used to record the time that the target object stays in the area once, and the time unit in Table 1 is milliseconds.
TABLE 1
| [PeopleID] | [ZoomID] | [InTime] | [OutTime - InTime] |
| 151 | 1466 | 1565591142222 | 5568 |
| 196 | 1466 | 1565591146472 | 247 |
| 209 | 1466 | 1565591147790 | 4439 |
| 194 | 1466 | 1565591147793 | 4166 |
| 232 | 1466 | 1565591149317 | 23386 |
| 247 | 1466 | 1565591150210 | 22759 |
| 293 | 1466 | 1565591206491 | 1264 |
It should be noted that the target object may be set to be a human, and of course, the target object may be changed according to the application scene, for example, in a zoo, the target object may include an animal, not only a human.
S13: and recording the dot-matrix diagram by using a frequency file, recording the file according to time, and obtaining and recording the entering times of each area.
Specifically, the number of times that an area is entered can be known from the time log file, because the time log file needs to record the time that each target object enters the area each time, so as to obtain the number of times that an area is entered, the frequency file can obtain the number of times that an area is entered by using the number of times that an area is entered, which is recorded by the time log file, for example, table 1 can know that the area 1466 is entered 7 times.
Specifically, the bitmap is stored by using a separate frequency file, and a file similar to the format of the hotspot configuration file is used, for example, the bitmap of [320 × 240] is subjected to traversal judgment and filled, then a filled bitmap of [320 × 240] is returned, the number of times that the region is passed is identified on each pixel point in each region on the bitmap in the frequency file, and the maximum identifiable value of each pixel point may be set to 100.
Specifically, the file naming format of the frequency file may be: h _ [ mac ] _ [ date ] _ [ time ]. h, can record the mac address, date and time, is convenient for searching, can change according to the actual application requirement certainly, and is not limited herein.
S14: and filling different colors into each region according to a preset filling rule by using the frequency file and according to the entering times of each region, and generating a hot spot region bitmap.
Specifically, each region is filled with a corresponding color by using the entry times and the colors corresponding to different times of each region recorded in the frequency file, so that a hot spot region bitmap is obtained.
Specifically, the preset filling rule may specify that different entry times correspond to different colors, for example, the entry times are 1 to 20 times of light green, 21 to 50 times of yellow, 51 to 100 times of red, and the like, and each region is filled with the corresponding color according to the entry times of each region, so as to generate a hot spot region bitmap.
It can be seen that, in the embodiment of the present invention, after the bitmap is generated at the management system end, the bitmap is sent to the device end, the device end records the entry time and the exit time of each region object by using the time recording file, the bitmap is saved while the frequency file, meanwhile, the entering time and the leaving time recorded according to the time recording file are recorded to count the entering times of each area, and marks the number of entries for each region to each region, finally based on the number of entries for each region, correspondingly, different colors are filled in each area according to a preset filling rule to generate a hot spot area dot matrix diagram, the generation process of the dot matrix diagram is simplified, the information required by the dot matrix diagram generation can be stored only by two files, therefore, real-time data collection and hot spot dot matrix diagram generation and updating can be realized at the equipment end, and timeliness is improved.
The embodiment of the invention discloses a specific hot spot area dot-matrix diagram generation method, and compared with the previous embodiment, the embodiment further explains and optimizes the technical scheme. Specifically, the method comprises the following steps:
specifically, the time recording file can be used for recording the stay time of each target object in each area in the bitmap, and the stay time duration data of each area is generated according to the stay time of each object in each area, for example, when the application scene is a market, each area corresponds to different commodity areas, and the attraction of the commodity to the client can be known through the stay market data, so that a corresponding report can be conveniently made.
Specifically, the bitmap generation process, as shown in fig. 2, may include S21 to S28; wherein the content of the first and second substances,
s21: and acquiring a shot picture, and converting the picture into an original bitmap.
Specifically, a picture of a real area of a bitmap to be generated is acquired through, for example, a camera, and the picture is converted into an original bitmap, wherein the area is not planned in the original bitmap.
S22: and establishing a coordinate system in the original bitmap, and receiving the vertex coordinates of the region.
Specifically, a coordinate system is established in the original bitmap, so as to receive vertex coordinates of each region required to be planned by the user.
S23: and connecting the areas in sequence according to the vertex coordinates of the areas to obtain the area boundary.
Specifically, the vertex coordinates corresponding to the respective regions are connected in the corresponding order, so that the respective boundary lines of each region can be obtained.
S24: and traversing the point coordinates of each pixel point in the original bitmap, and judging whether each pixel point is in the region or not.
Specifically, after the boundary of each region is determined, the pixel points in each region can be determined for each region, so that whether the target object enters the region can be determined subsequently, and whether each pixel point is in the region can be determined according to a corresponding algorithm, such as a cross point discrimination method, by traversing the coordinate points of each pixel.
S25: and if so, filling the ID corresponding to the region to the pixel point to obtain the region.
Specifically, if the pixel point is in the region, the ID of the region where the pixel point is located is filled for the pixel point to mark that the pixel point is located in the corresponding region, and a complete region can be obtained by filling all pixel points in one region.
S26: if not, filling default values to the pixel points.
Specifically, if the traversed current pixel is not in any one of the regions, a default value is filled in the pixel, for example, 0.
S27: and obtaining a dot matrix diagram according to the filling result.
Specifically, according to the filling results of S26 and S27, a complete bitmap including each region can be obtained, and the bitmap can be transmitted to the device side, so that the device side can generate a corresponding hotspot map.
Further, the process of determining whether each pixel point is in the region in S25 may include S251 to S256, as shown in fig. 4; wherein the content of the first and second substances,
s251: judging whether the current pixel point is positioned on the edge of the area or not;
s252: and if the current pixel point is located on the edge of the region, the current pixel point is located in the region.
Specifically, when the traversed current pixel point is located on the edge of the region, that is, on the boundary, the pixel point may be determined to be within the region.
S253: judging whether the two adjacent sides of the region are on the two sides of the ray of the current pixel point when the ray of the current pixel point passes through the intersection points of the two adjacent sides of the region based on a cross point number discrimination method;
s254: if the ray is positioned on the two sides of the ray of the current pixel point, the intersection point number with the intersection point is calculated as one;
s255: if the intersection points are not on the two sides of the ray of the current pixel point, the number of the intersection points with the intersection points is calculated as two.
Specifically, when determining whether a pixel point is in the region, the cross point number determination method determines whether an intersection point of a ray which is horizontally directed from the point as a starting point and a side of the region is an odd number, if so, the point is in the region, if 0 or even number is outside the region, and since there is a case where the current pixel point is outside the region and also intersects a vertex of the region, for example, as shown in fig. 3, the ray of the current pixel point S intersects vertex a, and at this time, the intersection point with the side of the region is an odd number, which causes an erroneous determination, therefore, when determining that the ray of the current pixel point passes through the intersection point of the adjacent two sides of the region, the adjacent two sides of the region are on both sides of the ray of the current pixel point, if the ray of the current pixel point is on both sides of the ray, the number of the intersection point with the intersection point is counted as one, for example, as shown in fig. 4, the adjacent two sides AB BC of the region and the ray of the current pixel point S are on both sides of the current pixel point S, the number of the intersection points with the intersection point is counted as one, and if the intersection points are not positioned on the two sides of the ray of the current pixel point, as shown in fig. 3, the adjacent two sides AB and BC of the area are positioned on the lower side of the ray of the current pixel point S, the number of the intersection points with the intersection point is counted as two, so that the misjudgment can be avoided.
S256: and ignoring the condition that the ray of the current pixel point is parallel to any side of the region.
Specifically, under the condition that the ray of the current pixel point is parallel to any side of the region, the ray has no intersection point with the side of the region, or an infinite number of intersection points coincide with the side of the region, and the condition is directly ignored and is not referred to.
Therefore, the accuracy in the region can be improved by the judging method of S251 to S256, it is ensured that the region can accurately cover each pixel point therein, and the accuracy of subsequently judging whether the target object enters the region is improved.
