Problems solved by technology

However, in practice, it is found that the target person identification and tracking method based on video surveillance is limited by the video surveillance range of the surveillance camera, and there are certain monitoring blind spots. When the target person leaves the video surveillance range, it is often difficult to continue tracking, making the target person tracking low efficiency

Embodiment 1

[0057] see figure 1 , figure 1 It is a schematic flowchart of a method for detecting a target person disclosed in an embodiment of the present invention. Such as figure 1 As shown, the target person detection method may include the following steps.

[0058] 101. The vehicle-mounted terminal acquires the biometric information of the detected person collected by the vehicle-mounted sensing device installed on the vehicle body within the vehicle monitoring range.

[0059] In the embodiment of the present invention, the vehicle-mounted terminal may include a central control large screen, a driving recorder, etc., which are not limited in the embodiment of the present invention. The vehicle-mounted sensing device can be a camera / video camera, photoelectric collection device, sound collection device, odor sensor, infrared sensor, etc. installed on the vehicle body, or a unit / module with a biometric information sensing function configured in the vehicle-mounted terminal. Accordin...

Embodiment 2

[0072] see figure 2 , figure 2 It is a schematic flow chart of another target person detection method disclosed in the embodiment of the present invention. Such as figure 2 As shown, the target person detection method may include the following steps.

[0073] 201. The vehicle-mounted terminal acquires the biometric information of the detected person collected by the vehicle-mounted sensing device installed on the vehicle body within the vehicle monitoring range.

[0074] 202. The vehicle-mounted terminal identifies and matches the biometric information of the detected person with the biometric information stored in the vehicle-mounted terminal.

[0075] 203. If the biometric information of the detected person does not match the biometric information stored in the vehicle-mounted terminal, the vehicle-mounted terminal calls the target person database corresponding to the information type of the biometric information in the cloud server; The information is the biometric i...

Embodiment approach

[0088] As an optional implementation, the method may also include the following steps:

[0089] The vehicle terminal uploads the biometric information of the detected person to the cloud server;

[0090] The cloud server receives the biometric information of the detected person uploaded by the vehicle terminal;

[0091] The cloud server queries and acquires the target person identification information associated with the detected person, and determines whether the target information type of the associated target person identification information includes the information type of the detected person's biological feature information;

[0092] If not, the cloud server obtains the newly added data type that does not match the target information type among the information types of the biometric information, and uses the biometric information corresponding to the newly added data type as the newly added target person identification information of the detected person, and The newly a...

Abstract

The embodiment of the invention relates to the technical field of a vehicle-mounted system, and discloses a target character detection method and system. The method comprises the following steps thata vehicle-mounted terminal obtains biometric information of a detected person collected in a vehicle monitoring range by a vehicle-mounted sensing device arranged in a vehicle body; the on-board terminal recognizes and matches the biometric information to obtain the matching result; according to that matching result, a vehicle-mounted terminal determines that the detected person matches any targetperson, a reminder function is triggered, and the matching result and the position information of the detected person are uploaded to a cloud server, so that the cloud server analyzes the identity type of the detected person according to the matching result, and transmits the matching result and the position information of the detected person to an external information publishing system corresponding to the identity type. By implementing the embodiment of the invention, the monitoring range can be enlarged, and the efficiency of searching and tracking the target person can be improved.

Description

technical field [0001] The invention relates to the technical field of vehicle systems, in particular to a target person detection method and system. Background technique [0002] In case investigation, the identification and tracking of specific persons (such as criminal suspects, missing children or lost elderly) is an extremely critical link. The traditional identification and tracking methods of target persons are based on video surveillance technology, through the monitoring cameras installed in specific places (such as streets), the video images acquired by the surveillance cameras are analyzed to realize the identification and tracking of target persons. However, in practice, it is found that the target person identification and tracking method based on video surveillance is limited by the video surveillance range of the surveillance camera, and there are certain monitoring blind spots. low efficiency. Contents of the invention [0003] The embodiment of the inven...
