Embodiment 1

[0024] see figure 1 , this embodiment provides an imaging device for generating a 3D model, the imaging device includes a support part, a bottom surface 11 and four 3D cameras 12 .

[0025] The four 3D cameras are arranged on the support part along a preset track line, and the projection of the preset track line on the bottom surface is a circle.

[0026] The distance between any two 3D cameras to the bottom surface is only greater than zero, and the shooting direction of each 3D camera is parallel to the bottom surface and the shooting direction is a point from the 3D camera to the vertical line, and the vertical line is the point passing through the vertical line. The center of the circle and a straight line perpendicular to the bottom surface.

[0027] Specifically, the preset trajectory in this embodiment is a cylindrical helix, and the 3D cameras are uniformly arranged on the cylindrical helix.

[0028] The 4 3D cameras are evenly distributed on the preset trajectory li...

Embodiment 2

[0041] This embodiment is basically the same as Embodiment 1, the only difference is:

[0042] For a target 3D image acquired by a 3D camera, the processing end is used to select a feature point in the 3D image captured by the 3D camera and obtain the distance from the feature point to the vertical line and the included angle of the target;

[0043] Then obtain the position of the feature point in the 3D image shot by the adjacent 3D camera of the 3D camera through the lead of the preset trajectory line and the distance between the 3D cameras, and compare the 3D image shot by the 3D camera with the adjacent 3D image The 3D images shot by the 3D camera are stitched by the feature points, wherein the target angle is the angle between the line connecting the feature point to the vertical projection point and the plane where the 3D camera and the axis are located.

[0044] In this embodiment, feature points do not need to be identified, and directly selecting feature points can gr...

Embodiment 3

[0050] This embodiment is basically the same as Embodiment 1, the only difference is:

[0051] The preset trajectory is two cylindrical helixes, the starting points of the two cylindrical helixes are both set on the bottom surface, and the leads of the two cylindrical helixes are the same.

[0052] Example 2

[0053] This embodiment is basically the same as Embodiment 1, the only difference is:

[0054] The preset trajectory is three cylindrical helixes, the starting points of the three cylindrical helixes are all set on the bottom surface, and the leads of the three cylindrical helixes are the same.

Abstract

The invention discloses an imaging apparatus and method for generating a 3D model. The imaging apparatus comprises a support portion, a bottom surface, and at least two 3D cameras. The at least two 3Dcameras are arranged at the support portion along a predetermined trajectory line, wherein the projection of the predetermined trajectory line on the bottom surface is a circle; a difference of distances between any two 3D cameras and the bottom surface is larger than zero; and the shooting direction of each 3D camera is parallel to the bottom surface and the shooting direction is a point from the 3D camera to a vertical line, wherein the vertical line is a straight line passing through the center of the circle and being perpendicular to the bottom surface. The imaging apparatus has the powerful anti-interference ability; a clear 3D model is generated; the obtained 3D image is calculated by the processor conveniently; and computing resources of the processor are saved.

Description

technical field [0001] The invention relates to an imaging device and method for generating a 3D model. Background technique [0002] A 3D camera is a camera made with a 3D lens. It usually has more than two camera lenses with a distance close to that of the human eye, and can capture different images of the same scene similar to what the human eye sees. Holographic 3D has more than 5 lenses on the disk, and the same image can be viewed in all directions through dot grating imaging or rhombus grating holographic imaging, as if you are on the scene. [0003] The first 3D camera So far the 3D revolution has all revolved around Hollywood blockbusters and major sports events. With the advent of 3D cameras, this technology is one step closer to home users. After the launch of this camera, we will be able to use 3D lenses to capture every memorable moment in life, such as a child's first step, college graduation celebration and so on. [0004] 3D cameras usually have more than ...
