The embodiments of the present invention will be described in detail below with reference to the accompanying drawings,
the first embodiment of the invention provides an intelligent retail cabinet, which comprises a window and a camera unit arranged on one side of the window, wherein the camera unit is arranged in the intelligent retail cabinet, and the window is at least constructed as a partial area of the side surface of the intelligent retail cabinet; the camera shooting unit and the window are respectively provided with a first polarizing film and a second polarizing film, and the polarization directions of the first polarizing film and the second polarizing film are perpendicular, so that when a user is positioned at the other side of the window, the user cannot see the second polarizing film, and the camera shooting unit cannot shoot an image positioned at one side of the user.
In this embodiment, an intelligent retail cabinet is provided, and the intelligent retail cabinet can sell various commodities, such as water, hamburgers, sausages and the like, but the invention is not limited to this. The intelligent retail cabinet is characterized in that a cabinet door is arranged on one side face of the intelligent retail cabinet, the whole side face of the intelligent retail cabinet can be constructed into the cabinet door, and partial area of the side face of the intelligent retail cabinet can also be constructed into the cabinet door. The cabinet door of the intelligent retail cabinet is provided with a window, the whole cabinet door of the intelligent retail cabinet can be set as the window, and partial area of the cabinet door of the intelligent retail cabinet can be set as the window. The intelligent retail cabinet is characterized in that a camera shooting unit is further arranged in the intelligent retail cabinet, when a user is outside the intelligent retail cabinet, after the user clearly sees the commodities in the intelligent retail cabinet through a window on the cabinet door, after one or more commodities purchased in advance are selected, at the moment, the camera shooting unit in the intelligent retail cabinet can shoot the commodities selected by the user, a bill is automatically generated for the commodities on the photo by utilizing an image commodity identification technology, and the user can take away the selected commodities after paying. However, in the prior art, no processing is performed on the window on the cabinet door, so that the camera unit can shoot the commodities outside the cabinet door and other complex scenes, and the accuracy of commodity identification is reduced.
In the present invention, as shown in fig. 1, the first polarizing film and the second polarizing film are respectively disposed on the camera unit and the window, and the polarizing directions of the first polarizing film and the second polarizing film are perpendicular, so that when a user is located at the other side of the window, the user cannot see the second polarizing film and clearly see the goods in the intelligent retail cabinet, and the camera unit cannot capture an image at one side of the user. As shown in fig. 1, the polarization direction of the first polarization film disposed on the camera unit is horizontal, that is, only light in the horizontal direction can pass through the first polarization film, the polarization direction of the second polarization film disposed on the window is vertical, that is, only light in the vertical direction can pass through the second polarization film, and as can be seen from fig. 1, only natural light in the vertical direction can enter the intelligent retail cabinet through the second polarization film disposed on the window, and because the light entering the intelligent retail cabinet is vertical, the light cannot pass through the first polarization film and further cannot enter the camera unit disposed with the first polarization film, and therefore, the camera unit cannot shoot a scene outside the intelligent retail cabinet. In the present invention, the polarization directions of the first and second polarizing films are not particularly limited as long as they are perpendicular, and for example, the polarization direction of the first polarizing film may be a vertical direction, the polarization direction of the second polarizing film may be a horizontal direction, and the like.
The intelligent retail cabinet provided by the embodiment of the invention has no special requirements on light outside the cabinet in the cabinet, and does not generate a light reflection phenomenon, so that a user can clearly see commodities in the cabinet from the outside of the cabinet door, and the camera unit can not shoot scenes outside the cabinet door, thereby not influencing a commodity identification algorithm and improving the accuracy of commodity identification.
