Description

Technical Field

[0001] The utility model relates to the technical field of three-dimensional reconstruction, and particularly relates to a three-dimensional modeling spherical acquisition device. Background Art

[0002] In the technical field of three-dimensional reconstruction, for high-quality three-dimensional modeling, there are relatively high requirements for the acquisition quality, accuracy and illumination of images; in the traditional manual shooting method, multiple manual adjustments are required, and a single object needs to be shot from multiple angles; due to the complexity of the three-dimensional modeling technology itself, a relatively large number of shooting samples and high-definition and accurate-angle images are required, so there will inevitably be some errors in manual shooting, such as incorrect image shooting caused by excessive angle deviation, unclear images caused by hand shaking, and slow speed of the manual shooting method.

[0003] In the prior art, there are a large number of image acquisition devices for assisting in three-dimensional modeling to acquire images, but the existing image acquisition devices all have the situations of complex adjustment methods of the acquisition device, unreasonable camera layout of the acquisition device, and lack of appropriate light sources.

[0004] For example, a Chinese patent, with the application number 201320302867.3, the application date of May 29, 2013, and the patent name of "A Spherical Panorama Shooting Bracket", is a utility model patent. Its technical solution is: a spherical panorama shooting bracket, including a spherical frame and 33 shooting control points arranged on the spherical frame. The spherical frame includes six annular brackets. Four of the six annular brackets are horizontally placed, and their annular planes are parallel to each other. The remaining two annular brackets are vertically placed, and their annular planes are perpendicular to each other and perpendicular to the annular planes of the other four annular brackets, for supporting the four horizontally placed annular brackets. The 33 shooting control points include one shooting control point at the top, and the other 32 shooting control points are arranged on the four horizontally placed annular brackets. Eight shooting control points are evenly distributed on each of the four horizontally placed annular brackets, and the intersection point at the top of the intersection of the two vertically placed annular brackets is the shooting control point; the technical solution of the above patent provides a solution to the problems of slow manual photographing and inaccurate angles.

[0005] However, in an environment lacking an appropriate light source, the above patent cannot acquire high-definition images, which will lead to the failure of three-dimensional modeling or a reduction in the quality of three-dimensional modeling. The situation of lacking an appropriate light source mainly refers to situations such as overexposure and lack of light source. Summary of the Invention

[0013] Furthermore, the cameras arranged at the intersections of the arc-shaped vertical brackets and the second annular bracket and the light source structures arranged at the intersections of the arc-shaped vertical brackets and the second annular bracket are staggered on the second annular bracket.

[0014] Furthermore, cameras are symmetrically arranged at equal intervals on both sides of the cameras arranged at the intersections of the arc-shaped vertical brackets and the second annular bracket on its arc-shaped vertical bracket, and cameras are arranged on the second annular bracket between adjacent arc-shaped vertical brackets.

Obviously, the described embodiments are some, but not all, of the embodiments of the present application.

[0035] Embodiment 1

[0036] As Figure 1As shown in the figure, a three-dimensional modeling spherical acquisition device includes a spherical device support, Camera 1, and a light source structure 2. Camera 1 is connected to a POE switch through an Ethernet cable, and the POE switch is connected to a power supply to provide network support and power support for Camera 1, realizing the interconnection and interoperability between Camera 1 and the acquisition software. When Camera 1 receives a shooting instruction from the acquisition software, multiple Camera 1s can shoot simultaneously, shoot alternately, or shoot alternately in different regions according to shooting control points. Different shooting methods are adopted according to specific shooting processes and requirements. At the same time, the shooting method of Camera 1 and the intensity of the light source are directly controlled by the acquisition software computer, and the acquisition software of the computer can be a well-known software commonly used by those skilled in the art. The light source structure 2 selected is a customized LED photography lamp with a high color rendering index, and the RA value is required to reach at least 97. The light source structure 2 is connected to a light source controller with a power supply through a cable to send a control signal to the light source structure 2, thereby controlling the brightness and switch of the light source. The light source controller is an existing technology in this field. For example, a common lamp switch is connected to a lamp through a cable, which is not the inventive point of the present invention and will not be elaborated here. The spherical device support includes a horizontal annular support and an arc-shaped vertical support 3, and the horizontal annular support is perpendicularly connected to the arc-shaped vertical support 3. Multiple light source structures 2 for providing light sources for the shooting object and multiple Camera 1s for taking pictures of the shooting object are arranged on the horizontal annular support and the arc-shaped vertical support 3, and Camera 1 and the light source structure 2 are staggered on the horizontal annular support and the arc-shaped vertical support 3.

The light source structure 2 is fixed on the spherical device support through bolts and clamps, and the light source structure 2 itself can adjust the light angle.

[0037] The sphere diameter of the spherical acquisition device can be adjusted according to the actual shooting application scenario. When the sphere diameter of the spherical acquisition device is larger, the setting points of Camera 1 and the light source are more; when the sphere diameter of the spherical acquisition device is smaller, the setting points of Camera 1 and the light source are fewer. The setting quantity of Camera 1 and the light source structure 2 changes according to the change of the sphere diameter of the spherical acquisition device, but the light source setting points need to be evenly distributed, and the setting points of Camera 1 need to ensure that there is an image overlap area of more than 30% between the pictures taken by two Camera 1s to ensure the clear details and accurate angles of the pictures and improve the quality and success rate of subsequent modeling.

[0038] The horizontal annular bracket includes a middle horizontal annular bracket, an upper horizontal annular bracket, and a lower horizontal annular bracket; the middle horizontal annular bracket is connected to the midpoint of the arc-shaped vertical bracket 3; the upper horizontal annular bracket is arranged above the middle horizontal annular bracket and is connected to the arc-shaped vertical bracket 3; the lower horizontal annular bracket is arranged below the arc-shaped vertical bracket 3 and is connected to the arc-shaped vertical bracket 3; both the upper horizontal annular bracket and the lower horizontal annular bracket are provided in multiple numbers, and multiple cameras 1 and multiple light source structures 2 are arranged above the upper horizontal annular bracket and the lower horizontal annular bracket, and the cameras 1 and the light source structures 2 are staggered on each horizontal annular bracket.

[0040] As Figure 1 shown, a three-dimensional modeling spherical acquisition device includes a spherical device bracket, cameras 1, and light source structures 2; the cameras 1 are connected to a POE switch through Ethernet cables, and the POE switch is connected to a power source to provide network support and power support for the cameras 1, realizing the interconnection and intercommunication between the cameras 1 and the acquisition software. When the cameras 1 receive the shooting instructions from the acquisition software, multiple cameras 1 can shoot simultaneously, take turns shooting, or take turns shooting in different regions according to the shooting control points; according to the specific shooting process and requirements, different shooting methods are adopted. At the same time, the shooting method of the cameras 1 and the intensity of the light source are directly controlled by the acquisition software computer, and the acquisition software of the computer is a well-known software commonly used by those skilled in the art; the light source structure 2 selected is a customized LED photography lamp with a high color rendering index, and the RA value is required to reach at least 97; the light source structure 2 is connected to a light source controller with a power source through a cable to send a control signal to the light source structure 2, thereby controlling the brightness and switch of the light source; the light source controller is an existing technology in the art. For example, a common lamp switch is connected to a lamp through a cable, which is not the inventive point of the present invention and will not be elaborated here; the spherical device bracket includes a horizontal annular bracket and an arc-shaped vertical bracket 3, and the horizontal annular bracket and the arc-shaped vertical bracket 3 are perpendicularly connected to each other; multiple light source structures 2 for providing light sources for the shooting object and multiple cameras 1 for taking pictures of the shooting object are arranged on the horizontal annular bracket and the arc-shaped vertical bracket 3, and the cameras 1 and the light source structures 2 are staggered on the horizontal annular bracket and the arc-shaped vertical bracket 3; fixing brackets, fixing holes, and threads are arranged on the top and bottom of the spherical device bracket; the cameras 1 are fixed on the spherical device bracket by bolts or clamps, and the lenses of the cameras 1 can be adjusted at an angle; the light source structures 2 are fixed on the spherical device bracket by bolts and clamps, and the light source structures 2 can adjust the light angle itself.

[0041] The sphere diameter of the spherical acquisition device can be adjusted according to the actual shooting application scenario. When the sphere diameter of the spherical acquisition device is larger, there are more setting points for the camera 1 and the light source; when the sphere diameter of the spherical acquisition device is smaller, there are fewer setting points for the camera 1 and the light source. The setting quantity of the camera 1 and the light source structure 2 changes according to the change of the sphere diameter of the spherical acquisition device. However, the light source setting points need to be evenly distributed, and the setting points of the camera 1 need to ensure that there is an image overlap area of more than 30% when taking pictures between the two cameras 1, so as to ensure the clear details and accurate angles of the pictures and improve the quality and success rate of subsequent modeling.
