The embodiment of the application provides a current banister device can solve present discernment face identification and need the pedestrian to look for the best recognition position of camera and display screen people department on one's side to bring faster discernment throughput and experience and feel, solve the problem that whole equipment heat dissipation and costly face identification realized. And the projector 300 is used for replacing a display screen for displaying, so that the potential safety hazard caused by the installation position of the display screen is further solved.
The embodiment of the application provides a current banister device, the following technical problem that can solve: firstly, the passing experience of the pedestrian passing barrier gate is better, the pedestrian passing barrier gate can be identified by approaching the barrier gate from the front side without the need of leaning on the pedestrian, and the image acquired by the projector projection camera can be seen through the baffle plate from the front side in real time, so that the identification time is shorter, the passing rate is improved, and the technical problem that the existing passage gate machine cannot use a large display screen and the potential safety hazard caused by using an independent display screen are solved; secondly, because the projector 300 is used for replacing a display screen, the problem of heat dissipation caused by the fact that the display screen works all the time and then is integrated with a camera and a background data module in one device in the prior art is solved, the problem of heat dissipation after splitting does not exist, and the reason that the display screen cannot be separated in the prior art is that the effect of an image collected by the camera needs to be displayed immediately so that a passer can compare the camera with a displayed image, so that the projector cannot be separately placed with the other two modules; thirdly, after the heat dissipation problem is solved, the stability of the product can be realized without the strict requirement on temperature like the prior art, so that the overall realization cost is reduced; fourthly, after the problem of heat dissipation is solved, the limitation of product installation does not exist, and therefore the environment adaptability is stronger.
In some implementation scenes, an independent camera group 200 is arranged on a rotating shaft of a machine body of the passing barrier gate device, the face image data of pedestrians is collected through the camera group 200 and is transmitted to the projector 300, the projector 300 is projected onto a barrier gate, and a physical mapping effect is finally formed on the surface of the gate through the cooperation of the above components.
In some implementation scenarios, when a pedestrian walks to an entrance and an exit of a gateway gate away from the pedestrian, within an optimal visual diameter range of 50-100cm from a camera device on a rotating shaft 400 of a body, a camera group 200 records data (the data is discrimination data of a face recognition system, and data acquisition needs to be performed on people entering and exiting the whole building or area before starting the device), and transmits the data to a receiving terminal of a projector 300 through internal plate data sensing, the projector 300 is arranged at the lower side of the gateway card swiping position, and projection work is performed after the terminal of the projector 300 receives the data. The camera group 200 adopts a high-definition wide-angle camera module, and ensures that the projection and the mapping process are not interfered by matching with a pedestrian stopping line on the ground. In addition, the sound and light suggestion of passing, static and the switching of passing light colour and voice prompt, fuselage pivot 400 machinery anticollision, the gate can be opened and closed automatically when exceeding rated force, and one card, alone, a floodgate, many infrared correlation detectors more than to realize preventing following and preventing pressing from both sides to make the overall layout accomplish each link interworking.
In some implementations, the projector 300 can be installed at the body below the card swiping area of the sidewalk, and embedded in the shell of the body, and then other parts and hardware modules of the projector 300 are installed and connected, and the appearance of the projector 300 is only partially highlighted; therefore, the overall appearance of the traffic barrier device is more simplified.
In some implementation scenarios, the first barrier baffle 130 and the second barrier baffle 140 are close to be parallel to the camera group 200, so that a pedestrian can directly view the camera group 200 after entering the barrier section, and the identification angle can be better found through the corresponding relationship between the projection effect and the camera group 200. An example of the passing process of the pedestrian through the passing barrier device is as follows:
when a pedestrian walks to the middle of the barrier and is ready to pass through face recognition, the camera group 200 sends the collected images to the projector 300 and the face image database 500, the projector 300 projects the images collected by the camera group 200 onto the first barrier 130 and the second barrier 140 at the same time, in other embodiments, the image of the first camera 210 is projected onto the barrier from the back by the first projector, and the image of the second camera 220 is projected onto the barrier from the front by the second projector. Because camera group 200's inclination, the banister baffle that adds in addition and camera group 200 are than closer reason, can acquire pedestrian's face data before the pedestrian banister interval more easily, and the pedestrian can be with being close to the image that the camera was gathered on the direct-view front baffle, accomplish to gather-the positive integral type of projection and experience, and the pedestrian need not the side face and looks for the identification angle with the display screen to let equipment carry out faster face identification and let the pedestrian pass through.
