Embodiment 1

[0059] Example as figure 1 Shown: The uniform identification system for electric power construction personnel includes: camera 1, information transmission network 3, and remote monitoring server 2. The camera 1 is connected to the remote monitoring server 2 through the information transmission network 3, the monitoring video reading module 28, the personnel detection module 21, the face detection module 22, the orientation detection module 23, the torso detection module 24, the safety helmet detection module 25, the safety helmet The text detection module 26 and the armband detection module 27 run on the remote monitoring server 2 . The on-site data collected by the camera 1 is sent to the remote monitoring server 2 through the information transmission network 3, and the remote monitoring server 2 sends the control information back to the camera 1.

Embodiment 2

[0060] Example two such as figure 2 Shown: the electric power construction personnel uniform recognition system runs in the DSP processor 41 of intelligent network camera 4, and recognition system includes: monitoring video reading module 28, personnel detection module 21, face detection module 22, toward detection module 23, torso Detection module 24 , helmet detection module 25 , helmet character detection module 26 and armband detection module 27 .

[0061] Surveillance video read-in module 28 is used for reading the data that camera 1 gathers, and personnel detection module 21 is used for detecting whether there is personnel to enter in the scene that camera 1 captures, and face detection module 22 is used for detecting the people's face part of entering personnel , the orientation detection module 23 is used to detect the orientation of the person relative to the camera 1, the torso detection module 24 is used to detect the torso of the person, the helmet detection modul...

Abstract

The invention discloses a uniform wearing identification method for the power construction site staff. The method comprises the following steps: detecting whether a person enters a site or not, detecting the head and the body of the detected person and the direction of the detected person relative to a camera, and detecting whether the person wears a safety helmet or not; if the person wears the safety helmet and the face or the back of the person is opposite to the camera, carrying out safety hamlet character detection in a head area; when one side of the person is opposite to the camera, carrying out armband detection in a joint area of the head and the body; according to safety hamlet and armband detection results, judging whether the person is a staff member or not; and if the detection results show that the person is not a staff member, sending an alarm prompt. The method provided by the invention has the beneficial effects that HOG features are combined with SVM classifiers; and the LBP operator is adopted for texture analysis of safety hamlet characters and an armband, so that rotation invariance, gray invariance and other outstanding advantages are achieved, and the illumination robustness is high.

Description

technical field [0001] The invention relates to a method for identifying uniforms, in particular to a method for identifying the uniforms worn by personnel at electric power construction sites. Background technique [0002] Due to the high risk of power system facilities, in areas such as power distribution rooms, it is not only necessary to carry out video monitoring of the entire repair and maintenance process of power facilities, but also to detect whether the personnel entering are professional staff. The armband is used as a sign of electric uniforms, and it can be determined whether the person is a staff member by detecting whether the person wears the armband combined with the text information on the helmet. If special personnel are arranged for inspection, it will consume a lot of manpower and material resources, so a video surveillance and detection method for identifying uniforms is needed. [0003] Chinese patent application (notification number: CN104408459A) is...
