The structured face information is displayed through the above information bar. The structured face information displayed includes: face image, identity information, appearance time, appearance location, feature information, appearance frequency, etc. Among them, the above-mentioned appearance location can also be displayed on the map, and the appearance location can also be understood as the location where the target person is captured by the camera. The appearance location can be identified by the camera or the face image, for example: the target person is king Second, after retrieving the structured face information of Wang Er, you can display the image of Wang Er's face in the information bar, you can display all the camera positions captured by Wang Er on the map, and use the camera logo to mark it. Use Wang Er's face image instead of the camera logo to mark, indicating that Wang Er has been captured in the place. For example, if Wang Er is captured through the camera of the A supermarket, mark a camera logo at the A supermarket on the map or in the A supermarket Mark a picture of Wang Er. The above option buttons can be used for secondary search, that is, after the search results are obtained and displayed, the secondary search is used to add new search features and obtain search results with more features and a smaller range. Of course, when acquiring the information to be retrieved, the option button can also be used to obtain the feature information to be retrieved.

In the above steps, since the retrieval results are displayed on the map, the retrieval results can be presented intuitively, eliminating the process of manual data collation for the user, and the retrieval results can be analyzed more quickly and intuitively.

It should be noted that the method for retrieving information provided by the embodiments of the present invention may be applied to devices for retrieving information for personnel, such as computers, servers, mobile phones, and other devices capable of retrieving information for personnel.

In the embodiment of the present invention, the information to be retrieved is obtained, and the information to be inspected includes the characteristic information of the target person; the information to be retrieved is retrieved in a database storing all the characteristic information of the person to obtain the retrieval result, and the retrieval result Including the portrait information of the target person and the position information of the target person; displaying the retrieval result on the map interface. Since the portrait information and location information of the target person are displayed on the map interface, the retrieval result can be intuitively presented.

Please refer to FIG. 9, which is a schematic flowchart of another method for presenting information for retrieving information provided by an embodiment of the present invention. As shown in FIG. 9, the method includes the following steps:

301. Obtain information to be retrieved, where the information to be inspected includes characteristic information of the target person;

302. Search the information to be retrieved in a database storing all personnel monitoring information to obtain a retrieval result, where the retrieval result includes the portrait information of the target person and the location information of the target person;

303. Sort the search results according to a preset sorting rule;

304. Display the search results in the sorting order on the map interface.

The retrieval result in step 303 is the retrieval result obtained from the database in step 302. The retrieval result may be the structured face information of the target person in the database. The structured face information includes: face image, identity information , Time information, location information, feature information and other information. The above preset sorting rules may be sorting by time, sorting by camera, sorting by frequency, sorting by identity information, etc. For example: sorting by time can be based on the capture time (that is, the time information in the structured face information) Sorting, you can put the latest snapshot at the front for sorting, or you can put the latest snapshot at the bottom for sorting. Sorting by camera can be sorted according to the captured camera number, the monitoring information of camera 1 is placed at the front for sorting, and the monitoring information of camera 2 is placed after the information of camera 1, under camera sorting, You can also sort the camera monitoring information. For example, the monitoring information in the No. 1 camera can also be sorted according to time. Sort by frequency of occurrence, it can be sorted according to the number of times the camera captures the target person, for example, the number of times the camera 1 captures the target person is 46 times, and the number of times the camera 2 captures the target person is 57 times, then you can press the High principle puts the search results of the No. 2 camera at the front for sorting; it can also be sorted by the number of times the target person was captured during a certain period of time. For example, on August 2, all cameras captured the target person 8 times in total, 8 On March 3rd, all cameras captured a total of 12 times for the target person. On August 4th, all cameras captured a total of 2 times for the target person. The search results of all cameras on August 3 can be placed at the forefront according to the high principle Sorting; it can also be the number of times a single target person is captured among multiple target personnel, for example, multiple target personnel are Zhang San, Li Si, and Wang Er, Zhang San is captured a total of 140 times, and Li Si is captured in total. The number of times is 230 times, and the total number of times Wang Er was captured is 300 times, then the search results of Wang Er can be sorted according to the principle of high priority. Sorting by identity information can be the identity information of a single target person among multiple target persons, for example, the last name of the target person is sorted by the family name, the same surname is sorted by the number of strokes, or by the first letter of the name, such as by target Sorting the age of personnel can also be a way of sorting by identity information.

It should be noted that the above sorting rules may be used alone or in combination, such as the combination of the above date and times.

In step 304, there may be one or more target persons retrieved. The above sorting may be the sorting rules in step 303. For example, when there is one target person retrieved, the retrieved target person ’s The search results are sorted and displayed according to time, so that the user can directly obtain the latest monitoring information of the target person, thereby helping the user to analyze the user's recent behavior, for example, the target person often appears in a place recently. You can also sort and display the search results of the target person retrieved according to the camera order, so that the user can intuitively know which camera the target person was captured by, so as to help the user analyze the location and target of the target person The movement trajectory of the person, such as how the target person moves from the place where it first appeared to the place where it last appeared. You can also sort and display the search results of the target person retrieved according to the frequency of occurrence, so that the user can more intuitively know at what time period or where the target person often appears, thus helping the user to analyze the target The behavior of personnel, such as whether the target person is going to work or off work. When there are multiple retrieval targets, the retrieval results of the retrieved multiple target persons can be sorted and displayed in order of frequency of occurrence, so that the user can intuitively know the travel situation of the multiple target persons.

It should be noted that step 303 is optional. In some possible embodiments, it is not necessary to sort the search results, and only needs to obtain the search results. Step 304 is an optional replacement for step 203 in the previous embodiment.

Optionally, the search result also includes information on the frequency of occurrence of the target person;

The displaying of the retrieval result in the map interface includes:

Display the frequency information on the map interface.

The above-mentioned frequency information can be statistically obtained based on the number of times the camera captures the target person. The above-mentioned frequency information displayed on the map interface can be displayed by numbers, for example: Retrieving Zhang San in the A and B areas respectively , Zhang San appeared 88 times in the A area and 23 times in the B area. You can use the number 88 in the A area corresponding to the map interface to indicate that the number of times Zhang San appeared in the A area is 88 times, and B in the map interface. The number 23 in the area indicates that Zhang San has appeared in the B area 23 times. Of course, the above numbers can also be marked under the camera, indicating the number of times each camera captures Zhang San, and if there are multiple target persons, the above numbers can also be marked below the face image to indicate each The number of times a person was captured. In addition, it can also be displayed on a regional heat map or on a date heat map.

It should be noted that the aforementioned frequency of occurrence may also be referred to as the number of occurrences, the number of times captured, or the number of times captured.
