Problems solved by technology
[0004] The purpose of the present invention is to solve the problem that in the technical field of epidemic prevention and control, when it is necessary to check the body temperature and health code of pedestrians, the existing technology can only detect a single pedestrian, and cannot realize the one-time detection of multiple pedestrians. Due to the technical problems, it has certain limitations in the scene with a large flow of people

Embodiment Construction
[0045] Such as figure 1 with figure 2 As shown, a pedestrian health monitoring method for security inspection system, it includes the following steps:
[0046] Step 1: Collect images of pedestrians passing through the access control, and mark the whole body, head and health code of the pedestrian. For the whole pedestrian, the marking information is where x 0 ,y 0 , x 1 ,y 1 Represent the upper-left and lower-right coordinates of the overall detection frame in the image, respectively, and i represents the number of pedestrians. For the header and health code, the tag information is Where j represents the class to which the human body part belongs, and (i, j) represents the part j of pedestrian i. The model can learn the affiliation relationship in the instance according to the label information. The head mark is divided into two categories: wearing a mask reasonably and not wearing a mask reasonably, and the health code is marked into three categories: red code, yel...

A pedestrian health monitoring method for a security check system comprises the following steps: step 1, acquiring pictures of pedestrians passing through access control in large public places such as shopping malls, hospitals, subway stations and the like, and marking the pictures; step 2, inputting the image into an instance-level pedestrian detection network for training, and identifying whether a pedestrian reasonably wears a mask and holds a health code; and 3, embedding the model into a security check system, and monitoring the health condition of the pedestrian. The invention aims to solve the technical problem that in the technical field of epidemic prevention and control, under the condition that the body temperature and the health code of a pedestrian need to be checked, only single detection can be performed on the pedestrian, and one-time detection of multiple pedestrians cannot be realized in the prior art, so that certain limitation exists in a scene with relatively large pedestrian flow.
Description
technical field [0001] The invention relates to the technical field of image detection and processing, in particular to a method for simultaneously detecting pedestrian body temperature, masks and health codes. Background technique [0002] The Chinese patent with the publication number CN113393604A discloses an access control identification method that is beneficial to epidemic prevention and control, which includes identifying devices through face recognition and body temperature detection, and simultaneously making access control judgments: first collect face information and body temperature information, and then compare Whether the face information and body temperature information meet the standards, so that the access control can detect the user's body temperature information while recognizing the user's face, so as to prevent users with abnormal body temperature from entering and leaving the access control. [0003] However, if the virus carrier has just been in contac...
