6 is a schematic diagram of an arrangement of an imaging module according to another embodiment of the present invention, and FIG. 7 is a schematic view of an arrangement of an imaging module according to another embodiment of the present invention. As shown in FIGS. 1, 6 and 7, the imaging module may perform simultaneous imaging of a plurality of attachment cords 100. And, when the imaging module performs imaging of the attachment code 100, the imaging unit provided in the imaging module is fixed to perform imaging of the passerby, or, or the imaging unit tracks the passerby while imaging the passerby. Can be done. Here, the imaging unit may be any one of the first imaging unit 210, the second imaging unit 220, or the third imaging unit 230 to be described below.

The imaging module may perform imaging of a plurality of attachment cords 100 attached to a person's clothing. In addition, the imaging module may perform imaging of a plurality of attachment cords 100 attached to clothes of several passengers. The imaging module is provided with the same two-dimensional code 110, or, each of the two-dimensional code 110 having a different two-dimensional code to capture images of each of the attached code 100, and the traffic analysis provided in the central processing unit 300 The unit 310 may analyze each two-dimensional code 110 to determine the number of passengers and analyze information about the passengers.

The imaging module includes: a first imaging unit 210 installed on a ceiling of a moving space and for imaging a head of a passerby; A second imaging unit 220 installed above the wall of the moving space and for imaging an upper body portion of a passerby; And a third imaging unit 230 installed under the wall of the moving space and photographing a lower body part of a passerby. As described above, the attachment cord 100 may be attached to any part from the head to the foot of the passerby.

The passerby analysis unit 310 may obtain an attachment code reference image, which is the clearest image of the images of the plurality of attachment codes 100. Specifically, in order to obtain an attachment code reference image, which is the clearest image among each attachment code 100, a plurality of attachment code 100 images obtained from one passer-by may be captured. As an embodiment, it is possible to image the attachment code 100 on the hat or top of the passerby using the first imaging unit 210, and the attachment code on the top of the passerby using the second imaging unit 220 100 may be imaged, and the attachment cord 100 on the bottoms or shoes of a passerby may be imaged using the third image pickup unit 230.

The imaging module may include an imaging unit that performs imaging at a rate of 70 to 120 frames per second. When the image pickup unit performs imaging of the attachment cord 100, the image of the attachment cord 100 may be formed differently according to the angle of the image pickup portion with respect to the attachment cord 100, so that the image pickup portion with respect to the attachment cord 100 When the angle is close to the vertical, it may be important to set the imaged image of the attachment code 100 as the reference image of the attachment code. In addition, it may be easy to use an imaging unit that performs imaging at high speed in order to perform imaging of the moving passer's attachment cord 100. Here, when the imaging speed of the imaging unit is less than 70 frames per second, it is not easy to capture the image of the moving passer's attachment cord 100, or when the angle of the imaging unit relative to the attachment cord 100 is close to vertical It may not be easy to acquire an image of (100). In addition, when the imaging speed of the imaging unit exceeds 120 frames per second, imaging is performed at a relatively higher speed, but the increase in imaging efficiency is insufficient and the cost of the imaging unit may increase.

The passerby analysis unit 310 may obtain an attachment code reference image, which is the clearest image of the images of the plurality of attachment codes 100. Here, the passerby analysis unit 310 may correct the attachment code reference image using a deep learning algorithm so that the attachment code reference image that is wrinkled or contaminated is close to the attachment code original image. The deep learning algorithm may be any one of a deep neural network, a convolutional neural network, or a recurrent neural network. The deep learning algorithm used in the system for determining the number of people of the present invention may be a known technology. In an embodiment of the present invention, it is described that the neural network as described above is used as a deep learning algorithm, but is not limited thereto.

As described above, since the attachment cord 100 is attached to the clothing, it may be slightly wrinkled or contaminated by predetermined contaminants. However, even if the attachment code 100 is slightly wrinkled or contaminated, when machine learning (deep learning) is performed on the matching of the attachment code reference image and the original attachment code image, the original state from the image of the crumpled attachment code 100 An image of the attachment code 100 can be derived. Specifically, for a portion of the 2D code 110 that is slightly wrinkled and curved, an image from which the bending is removed may be derived by analyzing the connection portion of the curved portion. For the site, an image from which contamination is removed can be derived by analyzing the connection site of the contaminated area.

The passerby analysis unit 310 may store an original image of an attachment code, which is an original image for the attachment code 100 provided in advance, and compare and analyze the attachment code reference image and the attachment code original image. And, the passerby analysis unit 310 repeatedly matches the attachment code original image and the attachment code reference image, and when the matching rate of the attachment code original image and the attachment code reference image is 90% or more, the attachment code 100 You can analyze the information of the passerby. Here, the attachment code reference image may be an image corrected by the deep learning algorithm.

First, as described above, the passerby analysis unit 310 continuously receives images for a plurality of attachment codes 100 in real time, and determines a reference image of an attachment code among the images of a plurality of attachment codes 100 received. It is obtained by matching, and here, the passerby analysis unit 310 may match and compare a plurality of attachment code reference images repeatedly with the attachment code original image. And, if the matching rate between the original image of the attachment code and the reference image of the attachment code is 90% or more, it is determined that the person wearing the attachment code 100 related to the reference image of the attachment code is passing through the moving space, and Information about the information can be classified separately and transmitted to a display unit that displays the screen.

Here, a plurality of attachment code reference images with a matching rate of 90% or more with respect to the attachment code original image may be selected. In this case, the image with the highest matching rate among the plurality of attachment code reference images is used to determine the information of the passerby. It can be selected as a reference image for the attachment code. Alternatively, an image with the highest sharpness among the plurality of attachment code reference images may be selected as an attachment code reference image for determining information of a passerby.

As described above, the passerby analysis unit 310 may determine the number of passers-by by determining information on passers-by based on the attached code reference image, and comprehensively analyzing the information. And, further, by analyzing information on each passer in each two-dimensional code 110, statistical data such as gender distribution of passers-by of passers-by, distribution of passers-by, and age distribution of passers-by are derived. It can be done, and it is also possible to analyze the matters on whether a specific passer-by has passed through any of the moving spaces.

As shown in FIG. 6, a plurality of imaging units may be disposed in a gate system through which a passerby passes. In the gate system, a plurality of passage guidance structures 400 may be formed so that the passage of the passenger is formed in a predetermined direction in the section in which the passenger passes. Here, for the application of the system for determining the number of people of the present invention, in each passage guidance structure 400, a 3-1 imaging unit 231 for photographing the attachment cord 100 attached to the shoe of the passer-by and the passer-by A 3-2 imaging unit 232 for imaging the lower body may be installed. In particular, the attachment cord 100 attached to the shoes of a passerby who regularly passes along the passage guidance structure 400 is easy to image, and accordingly, the attachment cord of the shoes by the 3-1 imaging unit 231 (100) Images can be easy to collect. In the case of a shoe, it is less wrinkled than a top or bottom, and a relatively constant movement line is formed, so that the image pickup unit can easily recognize the attachment cord 100 attached to the shoe. In addition, of course, the gate system may include the first imaging unit 210 or the second imaging unit 220.

As shown in FIG. 7, a plurality of imaging units may be disposed in a passage through which a passerby passes. In addition, in the passage, the second image pickup part 220 and the third image pickup part 230 may be formed on the wall of the passage, and the first image pickup part 210 may be formed on the ceiling. Here, each of the first to third imaging units 230 may be arranged and installed at regular intervals. In particular, the third imaging unit 230 for imaging the lower body of the passerby can increase the imaging ratio for the attachment cord 100 attached to the passer's shoe, and accordingly, the collection of the attachment cord 100 is It can be easy.

Hereinafter, a method for detecting and evacuating hazardous substances using the hazardous substance detection and evacuation guidance system of the present invention will be described.

Next, in the second step, the passer-by-passenger analysis unit 310 acquires an attachment code reference image, which is the clearest image of the images of the plurality of attachment cords 100, and the attachment code 100 prepared in advance. The original image of the attachment code for the attachment code and the reference image of the attachment code are repeatedly matched, and the passer-by analysis unit 310 may obtain an attachment code reference image for each image pickup unit.

In addition, in the third step, the passenger analysis unit 310 compares a plurality of attachment code reference images, analyzes the passenger information by the attachment code 100, and applies the attachment code reference image to the color analysis unit 320. And passer information to the data storage unit 330. Here, the passenger information transmitted to the data storage unit 330 may be transmitted to the analysis processing unit 340 again. Thereafter, in a fourth step, the color analysis unit 320 may analyze the color information using the attachment code reference image and transmit it to the analysis processing unit 340.
