A spherical three-dimensional camera system with lens groups is shown in figures 1 and 2 and comprises a sphere 1, a plurality of groups of lens groups 2 are mounted on the outer surface of the sphere 1, each lens group 2 comprises five lens units 3 with optical axes passing through the sphere center of the sphere 1, and the specifications, sizes and focal lengths of the five lens units 3 are the same.

As shown in fig. 3, the lens unit 3 includes an eyepiece 302 on the side close to the center of the sphere 1, and an objective lens 301 on the surface of the sphere 1.

As shown in fig. 4, the sphere 1 is internally mounted with an image sensor 4, a data processing unit 5, a storage module 6 and a power supply module 7.

The number and the positions of the image sensors 4 correspond to the lens units 3 one by one, and are located at the imaging surfaces of the lens units 3 corresponding thereto, and are configured to receive optical signals and convert the optical signals into electrical signals.

The data processing unit 5 is electrically connected with each image sensor 4, and is used for receiving part or all of the electric signals output by the image sensors 4 and splicing to form a three-dimensional stereo scene.

The storage module 6 is electrically connected to the data processing unit 5, and is configured to receive and store the three-dimensional stereo scene output by the data processing unit 5.

The power module 7 is electrically connected with the lens group 2, the image sensor 4 and the data processing unit 5.

Auxiliary light sources 8 are uniformly distributed on the surface of the sphere 1 to supplement light for a shooting scene; used in night time or dark light.

The sphere 1 is provided with a data transmission interface 9; when the data transmission interface 9 is connected to the computer terminal or the mobile phone terminal, the computer terminal or the mobile phone terminal receives and displays the three-dimensional scene, and a user can measure the distance between different objects in the three-dimensional scene at the computer terminal or the mobile phone terminal. The data transmission interface 9 is for outputting the three-dimensional scene stored in the storage module 6 to a computer or a mobile phone, so that a user can read and display the three-dimensional scene in some software such as VR software at the computer or the mobile phone.

A cover plate 10 is hinged on the sphere 1 and positioned at the data transmission interface 9 and used for protecting the data transmission interface 9 in a non-use state; the cover plate 10 is used for protecting the data transmission interface 9 in a non-use state, preventing dust from entering the data transmission interface 9 to cause failure, and preventing non-working personnel from using the system arbitrarily to transmit data of a three-dimensional scene privately.

In order to still perform a normal shooting operation without missing an image of a formed three-dimensional stereo scene even when one or some of the lens units 3 is damaged, the present invention is further configured as follows.

In the same lens group 2, one of the lens units 3 is a central lens 201, the other four lens units 3 are edge lenses 202, and the five lens units 3 are respectively located at five positions of a regular rectangular pyramid inscribed in the sphere 1, the four edge lenses 202 are respectively located at four vertices of the bottom surface of the regular rectangular pyramid, and the central lens 201 is located at the vertex of the regular rectangular pyramid opposite to the bottom surface.

A cone is expanded outwards from the real focus of the eyepiece 302 of the lens unit 3, i.e. the radiation area of each lens unit 3, the cone and the surface of the sphere 1 are intersected to form an arc surface, the arc surface has a unique inscribed square, the inscribed square is inscribed with the circumference of the arc surface, and the other four edge units are respectively placed on four vertexes of the inscribed square, so that the radiation areas of the four edge units can completely cover the radiation area of the central unit, and the inscribed square is also the bottom surface of the regular rectangular pyramid.

Assuming that the radius of the sphere 1 is R, the radiation angle of the lens unit 3 is α (the radiation angle is the angle of the cone radiation area of the lens unit 3 in the cross section), the focal length of the lens unit 3 is d, the included angle between the optical axis of the central lens 201 and the optical axis of any edge lens is β, and the included angle between the optical axes of two adjacent edge lenses 202 is γ, where R, α, d can all be determined when producing the sphere and the lens unit.

Then, in the same lens group, the included angle between the optical axis of the central lens 201 and the optical axis of any edge lens 202

The demonstration process is as follows:

as shown in fig. 5, fig. 5 is a simplified half-sectional view of a sphere, and the section passes through a central lens 201 and two diagonal edge lenses 202 in a group of lens groups 2, where a is one of the edge lenses, C is the other edge lens, B is the sphere center of the sphere, D is the real focal point of the central lens, E is the central lens, DE is the focal length of the central lens, AB and BC are the radii of the sphere, DE ═ D, AB ═ BC ═ R, ∠ ADC ═ α ABC ═ 2 β,

according to the sine theorem, the method for generating the sine wave,

then the process of the first step is carried out,

further, as shown in fig. 6, another regular rectangular pyramid may be formed at the centers of the four edge lenses 202 and the sphere 1, where A, B, C, D are the four edge lenses 202, H is the center of the sphere, O is the center of the bottom surface, and E is the emphasis point of BC, then ∠ BHO β Rsin β,

and gamma 2 ∠ BHE, then,

when the real focal points of the lenses are all converged at the sphere center of the sphere, i.e. d is equal to R, the included angle between the optical axis of the central lens and the optical axis of any edge lensIncluded angle between optical axes of two adjacent edge lenses

In any two adjacent lens groups, a lens group X and a lens group Y are set, a central lens of the lens group X is one of the peripheral lenses of the lens group Y, and a central lens of the lens group Y is one of the peripheral lenses of the lens group X.

The specific working principle is as follows: when any lens unit 3 on the sphere 1 is damaged, in the lens group 2 taking the lens unit 3 as the central lens 201, the other four edge lenses 202 can completely cover and replace the central lens 201 to perform shooting operation, so that a complete three-dimensional stereo scene can still be formed under the condition that some lens units 3 are damaged; in addition, in each lens group 2, the four edge lenses 202 can completely cover the radiation area of the central lens 201 in the lens group 2, so that each area can be photographed twice at the same time to improve the accuracy of the late contrast calibration.

Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments.
