Problems solved by technology

[0003] In the existing tracking technology, based on the monitoring system in a fixed position, the image of the person to be tracked is collected, and then the facial features are extracted for comparison. In addition, there may also be problems that the image cannot be sent in time and the feedback cannot be received in time due to the failure of the connection between the monitoring system and the data center.

Embodiment 1

[0023] figure 1 It is a schematic flow chart of a face tracking method provided by Embodiment 1 of the present invention. This embodiment is applicable to the situation of mobile tracking of face features, and the method can be executed by a face tracking system. The system can use software and / or implemented by hardware, and can be configured in a terminal and / or server to implement the face tracking method in the embodiment of the present invention.

[0024] Such as figure 1 As shown, the method in this embodiment may specifically include:

[0025] S110. The cloud receives the first vehicle location information of the first assisted tracking vehicle and the first facial feature sent by the first assisted tracking vehicle, and determines whether the first facial feature is a facial feature to be tracked.

[0026] Among them, the cloud can be understood as a software platform that adopts application virtualization. In the embodiment of the present invention, the cloud may ...

Embodiment 2

[0040] figure 2 It is a schematic flow chart of a face tracking method provided in Embodiment 2 of the present invention. In this embodiment, on the basis of any optional technical solution in the embodiment of the present invention, optionally, the first assisted tracking vehicle is received in the cloud. Before sending the first vehicle position information of the first assisted tracking vehicle and the first face feature, it also includes: the first assisted tracking vehicle collects the first image information of the environment where the first assisted tracking vehicle is located, and the first The face feature is extracted from the image information to obtain the first face feature, and the first vehicle position information of the first assisted tracking vehicle is obtained, and the first face feature and the first vehicle position information are sent to the cloud.

[0041] This embodiment, on the basis of any optional technical solution in the embodiment of the prese...

Embodiment 3

[0069] image 3 It is a schematic flow chart of a face tracking method provided by Embodiment 3 of the present invention. The embodiment of the present invention is a preferred embodiment of the above-mentioned embodiments of the invention. Taking the facial features of the fugitive as an example to be tracked, see image 3 As shown, the tracking process of fugitives can be divided into in-vehicle terminal and cloud-based parallel execution. Specifically, the method of the embodiment of the present invention may include the following steps:

[0070] 1. The first assistant to track the vehicle and send the vehicle's location information to the cloud for registration;

[0071] 2. Obtain the facial features and vehicle location information inside and outside the vehicle for the first assistance tracking;

[0072] 3. Use the acquired face features inside and outside the car as the first face feature, and send the location information of the first assisted tracking vehicle as the ...

Abstract

The embodiment of the invention discloses a face tracking method and system, and the method comprises the steps: a cloud end receives the first vehicle position information of a first auxiliary tracking vehicle and a first face feature, which are transmitted by the first auxiliary tracking vehicle, and determines whether the first face feature is a to-be-tracked face feature; if yes, the cloud end determines at least one second assistant tracking vehicle according to the first vehicle position information, and sends an assistant tracking notification corresponding to the to-be-tracked face features to the second assistant tracking vehicle, and the assistant tracking notification comprises the to-be-tracked face features; and the cloud end receives assistance tracking information which is reported by the second assistance tracking vehicle and corresponds to the assistance tracking notification. According to the technical scheme of the embodiment of the invention, not only can a method of getting rid of a fixed position and implementing mobile tracking be realized, but also the face features can be directly extracted and compared with the face features to be tracked in time after the tracking vehicle is assisted to collect the image information, so that the tracking efficiency is effectively improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of face recognition, and in particular to a face tracking method and system. Background technique [0002] At present, the public security system mainly uses the traditional Skynet monitoring system to collect images of persons to be tracked, and sends the collected images to the data center, and the data center performs face recognition, so as to realize the tracking process of persons to be tracked, or, based on Internet cafes, hotels, etc. The identification system tracks the person to be tracked. [0003] In the existing tracking technology, based on the monitoring system at a fixed location, the image of the person to be tracked is collected, and then the facial features are extracted for comparison. In addition, there may also be problems that images cannot be sent in time and feedback cannot be received in time due to the failure of the connection between the monitoring system a...
