[0089] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0090] Reference Figure 1 , shows an interaction diagram of a personnel positioning system of the present application, which includes a cloud server and a vehicle-mounted terminal device.

[0091] S101: The cloud server obtains feature information of at least one person to be located.

[0092] Among them, the people to be located can be certain specific groups of people, such as lost or missing elderly people, children, or people with a high risk factor, etc., which can be set according to different application scenarios.

[0093] For example, feature information can reflect certain characteristics of a person. Different people correspond to different features, so feature information can be used to identify people. Specifically, feature information can include any one or more of facial images, facial feature information, and posture information. A facial image is obtained by performing facial recognition processing on an image containing the face of the person to be located. The facial image is obtained by intercepting the original image based on the coordinates of the detected facial rectangle. Each facial image has corresponding facial feature information, which can include key point information or facial feature contour information. Posture information can include body shape information, walking movement information, and so on of the person to be located.

[0094] Any face detection method can be used in this application. The current face detection method can support the simultaneous detection of up to thousands of faces, support 360-degree plane rotation face detection, support left and right maximum 90-degree side face detection, obtain 1024-dimensional deep learning features of the face, etc. At the same time, it can also achieve millisecond-level extraction of key points of facial features in the image, identify the location of 105 key points of the face, and also identify the four attributes of gender, age, expression, and glasses of each detected face with high accuracy.

[0095] The characteristic information of the person to be located can be stored in a preset database, which can be used to transmit data to the cloud server via a specific interface to obtain the characteristic information of the person to be located. Alternatively, the characteristic information of the person to be located can be stored in another server, which can then push the characteristic information of the person to be located to the cloud server based on the needs of person location. The specific details are not limited.

[0096] In one implementation, the cloud server may update the feature information of at least one person to be located according to a first preset period. The first preset period may be a fixed time, such as 8:00 a.m. every day, or a fixed time interval, such as an update every 24 hours, etc., without limitation.

[0097] S102: The vehicle-mounted terminal device obtains feature information of the candidate person, where the feature information of the candidate person is identified from the image to be processed collected by the driving recorder.

[0098] In this step, the vehicle-mounted terminal device can first obtain the image to be processed captured by the driving recorder, and then identify the feature information of the candidate person from the image to be processed, or it can directly obtain the feature information of the candidate person identified by the driving recorder from the image to be processed, without specific limitation.

[0099] For example, in one implementation, the personnel positioning system also includes a driving recorder, which is deployed in the same vehicle as the vehicle-mounted terminal device and can transmit data. Specifically, the driving recorder in the personnel positioning system can capture images to be processed, identify feature information of candidate persons in the images to be processed, and transmit the identified feature information of the candidate persons to the vehicle-mounted terminal device.

[0100] It can be understood that compared with urban road monitoring, driving recorders have more flexible and wider coverage, and can cover areas that urban road monitoring cannot monitor, thereby reducing blind spots in urban monitoring and expanding the scope of personnel positioning.

[0101] After acquiring the candidate's characteristic information, the vehicle-mounted terminal device stores it locally for easy retrieval and query. In one implementation, the vehicle-mounted terminal device can also delete the acquired candidate's characteristic information based on a third preset period, thereby conserving memory usage. The third preset period can be a longer period, such as a week or a month.

[0102] S103: The vehicle-mounted terminal device uploads the candidate's characteristic information to the cloud server.

[0103] The vehicle-mounted terminal device can upload the characteristic information of a single candidate to the cloud server in real time. This means that each time a candidate's characteristic information is acquired, it is uploaded to the cloud server, thereby improving the real-time performance of personnel positioning. Alternatively, the characteristic information of multiple candidates can be uploaded to the cloud server at a time, thereby reducing the number of data transmissions and reducing the use of network resources.

[0104] For example, the vehicle-mounted terminal device may upload characteristic information of multiple candidate personnel acquired during the current period to the cloud server according to a second preset period. The second preset period may be a fixed time, such as 8:00, 12:00, or 16:00 daily, or a fixed time interval, such as once an hour, etc., without limitation.

[0105] S104: The cloud server compares the feature information of the candidate with the feature information of the person to be located for each person to be located. If the comparison is successful, the person to be located is taken as the target person and S105 is executed.

[0106] In this step, by comparing the feature information of the candidate person and the person to be located, if the feature information of the person to be located and any candidate person is highly similar or consistent, it can be considered that the comparison is successful, that is, the candidate person is also the person to be located.

[0107] In one implementation, the feature information may include facial feature information and facial images. The cloud server may compare the facial feature information and facial images of the candidate person and the person to be located. If both the facial feature information and the facial images are successfully compared, the cloud server determines that the feature information comparison between the candidate person and the person to be located is successful. Alternatively, the cloud server may select any one item of feature information for comparison, such as comparing only the facial feature information of the candidate person and the person to be located, or comparing only the facial images of the candidate person and the person to be located. If either one of the comparisons is successful, the cloud server determines that the feature information comparison between the candidate person and the person to be located is successful. The specific details are not limited thereto.

[0108] For example, in one case, the cloud server determines whether the feature information of the candidate person and the person to be located is successfully matched by comparing the facial feature information of the candidate person and the person to be located, wherein the facial feature information includes the key points of the facial features of the human face. Then, the cloud server can compare the key points of the facial features of the candidate person with the key points of the facial features of the person to be located, and determine whether there is a matching facial feature information of the candidate person and the facial feature information of any person to be located based on the positional relationship between the key points of the facial features. If so, the facial feature information of the candidate person and the facial feature information of the person to be located are successfully matched, that is, the feature information of the candidate person and the person to be located are successfully matched.

[0109] Alternatively, in another case, the cloud server determines whether the feature information of the candidate person and the person to be located is successfully matched by comparing the facial images of the candidate person and the person to be located. Then, the cloud server can extract facial features from the facial images, and then use feature matching algorithms such as K-means algorithm, cosine similarity algorithm or machine learning algorithm to match the facial features of the candidate person and the person to be located. If the facial features match successfully, the feature information of the candidate person and the person to be located is successfully matched.

[0110] S105: The cloud server returns a comparison success message to the vehicle terminal device.

[0111] The successful matching information can also carry relevant information of the target person, such as the reason why the target person needs to be located, age, name, and other information. This makes it easier for the car owner to provide assistance in locating the person or stay away from dangerous people in time.

[0112] In one implementation, when the feature information includes a facial image and facial feature information, the vehicle-mounted terminal device can first upload the facial feature information of the candidate person to the cloud server. Then, in this step, the cloud server compares the facial feature information of the candidate person with the facial feature information of the person to be located for each person to be located. If the facial feature information is successfully compared, the person to be located is used as the target person, and the first comparison success information of the facial feature information of the candidate person is returned to the vehicle-mounted terminal device.

[0113] Then, after receiving the first successful comparison information, the on-board terminal device uploads the facial image of the candidate person whose facial feature information is successfully matched to the cloud server. The cloud server further compares the facial image of the target person and the received facial image. If the facial image comparison is successful, the second successful comparison information of the candidate person's facial image is returned to the on-board terminal device, and then the on-board terminal device executes the subsequent steps.

[0114] That is to say, the vehicle-mounted terminal device first returns the facial feature information to the cloud server. When the cloud server determines that the facial feature information is successfully matched, it further returns the facial image. Only after the facial image is successfully matched, it is determined that the feature information is successfully matched. Among them, the vehicle-mounted terminal device does not need to send all facial images to the cloud server, and the facial feature information has a smaller data volume than the facial image. Therefore, the amount of data that the vehicle-mounted terminal device needs to send is also relatively small, which can save bandwidth and reduce resource usage. On the other hand, compared with the facial feature information, the facial image contains more feature information. That is to say, the second comparison based on the facial image has a higher confidence level than the first comparison based solely on the facial feature information, which is conducive to improving the accuracy of facial matching, making the personnel positioning system more accurate and the positioning result more confident.

[0115] Among them, in one implementation method, the vehicle-mounted terminal device uploads the facial feature information of multiple candidate persons to the cloud server each time, and the facial feature information of each candidate person has a unique corresponding identifier. In this case, the cloud server can compare the facial feature information of each candidate person with the facial feature information of the person to be located for each person to be located. If the facial feature information is successfully compared, the person to be located will be used as the target person, and the identifier of the facial feature information of the successfully matched candidate person will be used as the target identifier, and the first comparison success information will be returned to the vehicle-mounted terminal device, and the first comparison success information carries the target identifier.

[0116] In this way, after receiving the first successful comparison information, the vehicle-mounted terminal device can upload the facial image of the successfully matched candidate to the cloud server according to the target identifier, and then quickly return the corresponding facial image to the cloud server, thereby improving the system's response speed.

[0117] S106: After receiving the successful matching information, the vehicle-mounted terminal device obtains the positioning information of the candidate person who has successfully matched as the positioning information of the target person.

[0118] Among them, the positioning information may include the identity of the target person, the current time and location information. The location information may be the specific latitude and longitude information or street information of the target person, and may also include information such as the moving direction of the target person, without specific limitation.

[0119] In one implementation, after receiving a successful match, the vehicle terminal device can also play a preset audio message, such as "Dear driver, your vehicle has detected an important person. You can check the search progress at any time through the vehicle computer." This allows the driver to provide assistance in locating the person or promptly move away from the dangerous person. At the same time, the vehicle terminal device can also upload the target person's location information to the platform server.

[0120] The platform server is a server used to coordinate personnel positioning or other servers that need to locate the target person. Using the location information of the target person uploaded by the vehicle terminal device, the platform server can locate the target person. For example, the platform server can also analyze the location information of multiple target persons received to obtain the target person's trajectory information.

[0121] In addition, the vehicle terminal device can have a display interface, and the platform server can also generate positioning progress information for the target person and return it to the vehicle terminal device, which then displays the positioning progress information for the target person. This makes it easier for the vehicle owner to grasp the relevant information of the target person and respond in a timely manner, thus improving the user experience of the personnel positioning system.

[0122] Reference Figure 2 , shows a logical diagram of a person location method of the present application, wherein the driving recorder can be connected to a facial recognition system to perform facial recognition on the collected images to be processed, obtain the facial image and facial feature information of the candidate person, and then store the facial image and facial feature information of the candidate person in the vehicle terminal device. The cloud server periodically downloads the facial image and facial feature information of the person to be located from the database.

[0123] The vehicle-mounted terminal device can upload the acquired facial feature information of the candidate person to the cloud server once every hour. The cloud server will compare the facial feature information of the candidate person with the facial feature information of the person to be located for each person to be located. If the facial feature information is successfully compared, the first comparison success information will be returned.

[0124] Furthermore, the vehicle-mounted terminal device can upload the facial image of the successfully matched candidate to the cloud server. The cloud server compares the facial image of the target person and the facial image of the successfully matched candidate. If the facial image is successfully matched, a second successful comparison information is returned. In this way, the vehicle-mounted terminal device can play the preset audio and upload the obtained candidate's positioning information as the target person's positioning information to the platform server.

[0125] From the above, it can be seen that in the solution disclosed in the present application, on the one hand, the characteristic information of candidate personnel is identified from the images to be processed collected by the driving recorder, which has a more flexible and wider coverage compared to urban road monitoring. On the other hand, the characteristic information of candidate personnel is uploaded by the vehicle-mounted terminal device, and the cloud server only needs to compare the characteristic information, and does not need manual analysis of the collected images. Moreover, the amount of data that needs to be transmitted in the process of personnel positioning is relatively small, thereby improving the efficiency of personnel positioning.

[0126] Reference Figure 3 , shows a flowchart of the steps of a personnel positioning method of the present application, which is applied to a vehicle-mounted terminal device and may specifically include the following steps:

[0127] S301: Acquire feature information of a candidate person, where the feature information of the candidate person is identified from an image to be processed collected by a driving recorder.

[0128] S302: Uploading the characteristic information of the candidate person to the cloud server, so that when the characteristic information of the candidate person is successfully compared with the characteristic information of any person to be located, the cloud server will take the any person to be located as the target person and return a comparison success message.

[0129] S303: After receiving the successful matching information, the positioning information of the candidate who has successfully matched is obtained as the positioning information of the target person.

[0130] In one implementation, the feature information includes a facial image and facial feature information, and uploading the feature information of the candidate to a cloud server includes:

[0131] Uploading facial feature information of the plurality of candidate persons to the cloud server, so that when the facial feature information of any candidate person is successfully compared with the facial feature information of any person to be located, the cloud server will take the any person to be located as the target person and return a first comparison success message;

[0132] After receiving the first successful comparison information, uploading the facial image of the candidate person whose facial feature information is successfully compared to the facial image to the cloud server, so that the cloud server returns a second successful comparison information if the facial image of the target person and the received facial image are successfully compared;

On the other hand, the characteristic information of candidate personnel is uploaded by the vehicle-mounted terminal device, and the cloud server only needs to compare the characteristic information, and does not need manual analysis of the collected images.
