This invention relates to an imaging device, specifically to a matrix imaging device that can capture multiple two-dimensional images and synthesize them into a three-dimensional image.

Three-dimensional modeling technology has received considerable attention in modern times. Generally, 3D modeling refers to calculating and restoring the 3D spatial information of a real scene or object based on the image captured by the camera through a reconstruction algorithm.

The other is to use algorithms such as MVS (Multi View Stereo) to align and stitch multiple captured two-dimensional images into a three-dimensional image. However, this type of algorithm consumes too much resources and is not conducive to computing on devices with limited resources. Furthermore, the selection of matching positioning parameters between multiple images is still too complicated. There are also other ways to perform 3D modeling through photography, but the splicing process between each 3D image still relies on a lot of manual operations or complex operations.

The base 110 is used to place an object O to be tested, which includes a plurality of gradient color rings 111 . The imaging module 120 is disposed around the base 110 and includes a plurality of cameras 121 arranged in a matrix. The imaging module 120 can simultaneously capture multiple two-dimensional images including partial areas of the object O and partial areas of the gradient color rings 111 through the cameras 121, and based on the colors of the gradient color rings 111, The multiple two-dimensional images are combined into a three-dimensional image corresponding to the geometric shape and color of the object O based on the imaging position of the object O and the color of the object O.

Each camera 121 can be installed on a camera, a mobile phone, a laptop, a tablet computer, or other devices that can be equipped with the camera 121 . When the imaging module 120 captures multiple two-dimensional images of different areas of the object O through the multiple cameras 121, it also captures multiple two-dimensional images of different areas of the gradient color ring 111 of the base 110. In other words, a single two-dimensional image captured by each camera 121 simultaneously includes a partial region image of the object O and a partial region image of the gradient color ring 111 of the base 110 .

The multiple cameras 121 in the imaging module 120 can be arranged in various ways. In Figure 1, a plurality of cameras 121 are arranged coaxially along a straight line to form a linear array. Furthermore, multiple sets of coaxially arranged cameras 121 are arranged into a two-dimensional linear array. The number of cameras 121 is not particularly limited. A larger number of cameras 121 can capture a larger number of two-dimensional images, which helps synthesize a three-dimensional image that is closer to the true geometric shape and color of the object O to be measured. The linear array formed by the arrangement of the cameras 121 may be a one-dimensional linear array, a two-dimensional linear array or a three-dimensional linear array. In Figure 2, multiple cameras 121 are arranged in a circular array. In other words, the plurality of cameras 121 form a ring around the object O to capture multiple two-dimensional images that simultaneously include a partial area of the object O and a partial area of the gradient color ring 111 of the base 110 . Similarly, the annular array can also be a one-dimensional annular array, a two-dimensional annular array or a three-dimensional annular array.

Each gradient color ring 111 of the base 110 may include multiple gradient color areas. Blocks 111a, 111b, 111c. For example, in Figure 3, the base includes three gradient color rings 111, and each gradient color ring includes three gradient color blocks 111a, 111b, and 111c.

The colors of each gradient color block 111a, 111b, 111c can be the same or different. In one embodiment, the gradient color block 111a may include red and its gradient colors, the gradient color block 111b may include blue and its gradient colors, and the gradient color block 111c may include green and its gradients. As for the gradient color system, the colors of the gradient color blocks 111a, 111b, and 111c may also include a gradient color system composed of any of the aforementioned colors. In another embodiment, the gradient color block 111a may include cyan and its gradient colors, the gradient color block 111b may include magenta and its gradient colors, and the gradient color block 111c may include yellow. The colors of the layer color blocks 111a, 111b, and 111c may also include a gradient color system composed of any of the aforementioned colors.

In this creation, the gradient color blocks 111a, 111b, and 111c use a color system, which is red, green, and blue. It can also be called the three primary colors of color because it is the basic color light and cannot be decomposed. Can be combined into any color. In another color system, they are yellow, cyan and magenta, which can also be called the three primary colors of color. They are based on red mixed with green to get yellow, green mixed with blue to get cyan, and blue mixed with red to get magenta. . By mixing the three primary colors of light or the three primary colors of pigments in different proportions and intensities, complex and close-to-real colors can be obtained. However, the above color system is only an example. More types of gradient color blocks 111a, 111b, and 111c may be used depending on different purposes. The number of gradient color blocks may be three or more, and the color system may not necessarily be the same. As above, use three A color system, the number of colors can be three or more, without special restrictions.

Generally, when 3D image modeling of an object under test is performed by synthesizing multiple 2D images, whether the true 3D geometric form and color corresponding to the object under test O can be completely restored is the most critical issue. In this creation, a gradient color ring 111 is arranged on the base 110 . When capturing the two-dimensional image of the object O to be measured, the two-dimensional images of the different gradient color blocks 111a, 111b, and 111c of the gradient color ring 111 are simultaneously captured in a single two-dimensional image, and at the same time, the object to be measured is The imaging position of the object O and the color of the object O are also captured together, and based on the colors 111a, 111b, and 111c of the gradient color blocks of the gradient color ring 111, the image of the object O is captured. Based on the position and color of the object to be measured O, image recognition analysis and image synthesis calculations are performed. In this way, the accuracy of the two-dimensional image splicing and synthesis of each part of the object O is increased. At the same time, the gradient transition colors of the gradient color blocks 111a, 111b, and 111c are used as the reference color basis for image synthesis calculations, reducing unnecessary color consumption, increasing image synthesis efficiency, and improving the reality of three-dimensional image modeling.

As mentioned before, the multiple cameras 121 of the imaging module 120 can be arranged in a linear array or an annular array. Thereby, there is no need to install a large number of cameras 121 , and fewer cameras 121 can be used to capture multiple partial regions of the object O and partial regions of the gradient color blocks 111 a , 111 b , and 111 c of the gradient color ring 111 . The two-dimensional image will reduce the use of the camera 121 and improve the shooting efficiency. When rotating the object O or the imaging module 120, the object can be rotated 360 degrees at a certain angle. When more 2D images are taken, more detailed 3D images can be synthesized.

In the embodiments shown in Figures 4 and 5, each camera 121 can be at different angles relative to the object O to capture images of different parts of the object O. In other words, the imaging angle of each camera 121 relative to the object O is adjusted to simultaneously capture various partial areas of the object O and partial areas of the gradient color blocks 111a, 111b, and 111c of the gradient color ring 111 at various angles. two-dimensional image.
