Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.

As shown in fig. 1 and 2, a smart camera apparatus 1 according to an embodiment of the present invention includes: a camera 20 and at least two opto-mechanical devices 30. Specifically, the optical engine 30 is connected with the camera 20, wherein the optical engine 30 forms a continuous projection area 15, and the continuous projection area 15 is defined in the shooting area of the camera 20.

It can be understood that at least two optical machines 30 are provided, the projection areas 31 of the at least two optical machines 30 together form the continuous projection area 15, and the projection area of the continuous projection area 15 is wide relative to the projection area of a single optical machine, so that under the condition of the same shooting area, the installation distance of the optical machines 30 relative to the object can be closer, and thus, higher definition and resolution can be achieved.

Preferably, the projection area 31 of one optical machine 30 partially overlaps with the projection area 31 of at least one optical machine 30 of the remaining optical machines 30, so that the possibility that the image quality is not clear due to the fact that a partial area is not irradiated by the optical machine 30 in the shooting area of the camera 20 is reduced, and the overall definition and resolution of the image quality can be further improved. In the region where the projected regions 31 overlap, the image can be made seamless by software processing. In addition, for a three-dimensional stereo space, the projection of a single optical machine 30 in a shooting area has limitation, and at least two optical machines 30 project from different angles, so that the details of a 3D image of a shooting object can be increased.

It can be understood that the at least two optical machines 30 mean that the intelligent image capturing apparatus 1 may include two optical machines 30, may also include three optical machines 30, may also include four optical machines 30, and still another or more optical machines 30, which may be set according to actual needs.

Specifically, to explain more specifically by taking an example in which the smart camera apparatus 1 includes two optical machines 30 and is a smart camera, the smart camera apparatus 1 employs a DLP (Digital Light processing), as shown in fig. 1, when the shooting area requirement (i.e., the area to be shot) is an area of height H1 and width V1, since the projection area 31 becomes large as the distance increases, in order to satisfy both:

(1) ensuring that the continuous projection area 15 completely covers the required area of the object to be shot so as to obtain complete modeling;

(2) it is ensured that the camera 20 is close enough to the subject to obtain as sharp an image as possible.

Therefore, the shooting area of the camera 20 needs to be completely overlapped with the requested area of the object, the distance between the intelligent camera 1 and the plane where the object is located is L1, in the case of the dual-optical-system 30, the continuous projection area 15 is enlarged, at the same distance L1, the continuous projection area 15 is not only completely overlapped with the requested area of the object, but even larger than the requested area of the object, and at this time, to satisfy the condition (2), the distance between the intelligent camera 1 and the plane where the object is located can be shortened by less than L1, so that the picture shot by the camera 20 can achieve higher definition and resolution, and the picture is more uniform, sharper in color, high in light efficiency and high in brightness. The light machine 30 projects to generate light and dark stripes, a three-dimensional depth map is formed by combining the algorithm and image processing with the pictures shot by the camera 20, and the overlapping area between the projection areas 31 of the two light machines 30 can be processed by software to enable the images to form seamless images.

It should be noted that the intelligent image capturing device 1 may also be a 2D/3D photographing camera or a video recorder capable of photographing, and further may be a camera that collects data to form a 3D effect model.

According to the intelligent camera device 1 provided by the embodiment of the invention, the at least two optical machines 30 are arranged, the continuous projection area 15 can be enlarged, and under the condition of the same shooting area, the optical machines 30 can be closer to a shot object, so that the picture has high light efficiency and high brightness, and therefore, the intelligent camera device 1 has higher definition and resolution, and the shot picture is more uniform and has sharper color.

According to some embodiments of the present invention, the housing 10 defines a mounting cavity, and the housing 10 is provided with a first window 11 and a second window 12 which are spaced apart. The camera 20 and the at least two photomachines 30 are arranged in the mounting cavity, the lens of the camera 20 is opposite to the first window 11, and the emitting port of the photomachines 30 is opposite to the second window 12, so that the camera 20 and the photomachines 30 are mounted.

Further, the two cameras 20 can be unfolded to shoot from different viewing angles, and collect the position, posture, light and shade parameters of the object to be shot from different angles, so as to form a more stereoscopic picture effect.

Further, the center of the shape formed by the connecting lines of the centers of the at least two light engines 30 is located on the midpoint of the connecting line of the center of the first sub-window 112 and the center of the second sub-window 114. Therefore, the light and shadow at each position of the continuous projection area 15 formed by the optical machine 30 in the shooting area of the camera 20 can be more uniform, the limitation of the shooting area is reduced, and the definition and the brightness of the image quality are further improved.

For example, as shown in fig. 2, the intelligent camera device 1 according to an embodiment of the present invention includes two optical machines 30, the two optical machines 30 are respectively fixed on the upper and lower sides of the optical machine mounting plate 40 along the vertical direction, a connecting line of centers of the two optical machines 30 is in a straight line, a center of the straight line is a midpoint of the connecting line of the two optical machines 30, and as shown in fig. 2, the midpoint of the connecting line of the two optical machines 30 coincides with a midpoint of a connecting line of centers of the first sub-window 112 and the second sub-window 114. Or as shown in fig. 3, the intelligent camera device 1 according to an embodiment of the present invention includes three optical machines 30, one optical machine 30 is disposed above the optical machine mounting plate 40, two optical machines 30 are disposed below the optical machine mounting plate 40, a connecting line between every two optical machines 30 forms an equilateral triangle, and a center of the equilateral triangle coincides with a midpoint of a connecting line between a center of the first sub-window 112 and a center of the second sub-window 114 as shown in fig. 3.

This secures the optical engine 30 in the housing 10, reducing the possibility of the optical engine 30 moving in the housing 10. Further, the part of the optical machine 30 generating more heat can be arranged to be tightly attached to the optical machine mounting plate 40, so that the heat can be transferred out through the casing 10 by the optical machine mounting plate 40 to achieve the purpose of heat dissipation of the optical machine 30.

Further, as shown in fig. 2, the number of the optical machines 30 is two, and the two optical machines 30 are respectively fixed to the upper and lower sides of the optical machine mounting plate 40 along the vertical direction, it can be understood that the continuous projection area 15 formed by the two optical machines 30 is within the shooting area of the camera 20, because the continuous projection area 15 formed by the two optical machines 30 has a wider range, when the same required area of the object to be shot is required, the distance between the optical machines 30 and the camera 20 and the object to be shot is shorter, and thus each imaging effect is improved.

Further, the quantity of ray apparatus 30 is two, and two ray apparatus 30 are fixed in the left and right sides of ray apparatus mounting panel 40 respectively along the horizontal direction, and it can be understood that, the continuous projection area 15 that two ray apparatus 30 formed is in camera 20's shooting region, because the continuous projection area 15 scope that two ray apparatus 30 formed is wider, when the identical object of shooing required region of requirement, ray apparatus 30 and camera 20 are closer apart from the object of shooing, therefore each item formation of image effect all can improve. Accordingly, the distance between the two optical machines 30 is not limited, and can be set according to actual needs.

Further, the right side of the projection area 31 of the optical engine 30 positioned on the left side coincides with the left side of the projection area 31 of the optical engine 30 positioned on the right side. Therefore, the possibility that the projection area 31 of the left optical machine 30 and the projection area 31 of the right optical machine 30 have discontinuous areas when the continuous projection area 15 is formed can be reduced, and the possibility that dark shadows exist in the shooting area of the camera 20 is reduced.
