Abstract

The invention relates to a design of a 360-degree panoramic three-dimensional camera shooting realization method, in particularly to a 360-degree panoramic three-dimensional camera system. The 360-degree panoramic three-dimensional camera system comprises a suspension bracket, a platform guide structure, a camera distance regulation structure and other parts. The invention is characterized in that 360-degree all-directional three-dimensional demonstration is realized, the camera space can be adjusted according to the imaging zoom requirement, and the shortcoming that the 3-dimensional imaging effect is bad due to the change of a camera focal length is compensated.

Description

360 degree panorama 3 D stereo camera systems

Technical field

This invention relates to the design to the 3 D stereo shooting implementation method of showpiece; The particularly drive mechanism of distance adjustment mode design between two video cameras; And regulate the camera spacing according to imaging requirements, be 360 degree stereo camera apparatus and methods with widespread use.

Background technology

The history that the stereo camera shooting technology rises existing decades; Early stage stereo camera shooting stresses to give the visual impact in space; But because traditional technology cost is high, means are complicated, the vision impression is not so good; Now stereo camera shooting technology is ripe gradually, the impression that lively space image true to nature is in the action to the people.

Over nearly 5 years, Chinese and even global three-dimensional camera shooting technology adopts three-dimensional camera can carry out the shooting of digital three-dimensional program easily all in develop rapidly.But at present the 3D three-dimensional camera system all is to take at line slideway, perhaps controls the shooting route by the people, is difficult to realize the accurate location of distance between robotization control that 360 degree panoramas are showed and stereo camera.

Summary of the invention

For reappearing the visual custom of human eye; Three-dimensional film adopts two-shipper to take, and the certain physical spacing is arranged between the video camera, and the viewers wear glasses are with the two-way separation of images when projection; Right and left eyes is seen the picture that left and right sides video camera is taken respectively, thereby obtains three-dimensional impression.

360 degree panorama 3 D stereo camera systems are that object or fixed scene are carried out the comprehensive automatic shooting of 360 degree; And realize the effect of 3D three-dimensional imaging through two video cameras; Distance through regulating between the two video camera seats in the plane solves the doubly deficiency of back 3D effect change of camera review change, to obtain to meet the three-dimensional impression of visual custom.In this invention application process, two video cameras can be adjusted the distance between two video cameras automatically according to times adjusting situation of change, reach best 3D solid show effect.

In order to reach showing the effect of scene or the comprehensive displaying of object 360 degree, the present invention provides a kind of 360 degree full-view stereo image pickup methods.Said technical scheme is following:

360 degree full-view stereo photography equipment comprise: to required circular suspension bracket, the traction video camera carries out the platform of circus movement, is used for regulating gear train and two video cameras of distance between video camera on the platform to camera alignment.

The present invention is fixed on institute with suspension bracket will show that above the object, its radius is 2.5 meters.

Platform is put on the suspension bracket, carries out 360 degree motions around showpiece through motor and guiding device.

Gear train is used to regulate the distance between two video cameras.

Embodiment

Embodiment 1

With reference to Fig. 2 is the suspension bracket that carries picture pick-up device, and this suspension bracket comprises the web member above showpiece 3 that is used for fixing, the beam 1 and the platform plane of movement track 2 of carrying platform operation planar tracks.

Wherein Fig. 3 is that guide platform centers on the mechanism principle that showpiece carries out 360 degree stereoscopic shootings, and 2 is platform operation section plans among the figure.Through being installed in the guide wheel channeling conduct of platform below, guaranteed that platform can carry out circular motion.

Through platform motion direction speed manual or that program setting is good, the visitor can carry out watching of 360 degree to showpiece, and the same excessively camera system that platform carried reaches the effect of three-dimensional imaging.

Embodiment 2

With reference to Fig. 4, the invention provides a kind of drive apparatus of regulating distance between the camera, this equipment comprises:

Fixed cameras platform 7, leading screw 8, moveable platform 9, arc guide rail 10, driving block guide pole 11, support 12, arc guide rail slide block 13, driving block 14.

Fixed cameras platform 7 is used for fixing one of them of two video cameras, and video camera should point to the circular suspension bracket center of circle fixedly the time, just the article that will show.

When three-dimensional imaging need change far and near effect, regulate the distance between two cameras through the leading screw 8 of driven by motor.

Moveable platform 9 is used for fixing another camera, becomes the required camera system of stereo camera shooting with the camera set on the platform 7.When mounted need according to the effect that will reach come by the response between camera apart from camera is installed.

Arc guide rail 10 is one section circular arc that the circle with suspension bracket institute stroke coincides, and so just can the three-dimensional imaging effect changed during around showpiece rotation shooting at platform.

Driving block guide pole 11, arc guide rail slide block 13, driving block 14 and leading screw 8 have limited moveable platform 9 corresponding degree of freedom respectively, and mobile camera can be moved according to the direction of arc guide rail 10, and are that moveable platform 9 provides the required power that moves.

The type of belt drive of this drive apparatus employing servomotor and ball-screw reaches the purpose of distance between accurate control two video cameras, for three-dimensional imaging provides accuracy guarantee.

Fig. 5 is how two cameras regulate the synoptic diagram of the respective between them according to response parameter.Fixing Camera Platform 7, the motor 15 of drive leading screw, adjustable camera platform 9, arc orbit 10, leading screw 8.

Wherein:

A leading screw platform is apart from the motor horizontal range.

B leading screw platform is apart from the distance of leading screw mid point.

C leading screw central point is to the distance (leading screw and great circle points of tangency) of motor.

3 ° is design angle.

R is the distance that leading screw arrives the great circle center, is 2.5 meters.

α is the angle of back, location two cameras.(α manually confirms according to the size and the experience of image distance)

Annotate: it is identical with the center line radian to go up lower railway, and the center of circle is different.

1 when two camera angle during less than 3 °

$\tan (3-\mathrm{\α})=\frac{b}{r}$

a＝c-b

So

a＝c-r*tan(3-α)

2 when two camera angle during greater than 3 °

$\tan (\mathrm{\α}-3)=\frac{b}{r}$

a＝b+c

So

a＝c+r*tan(α-3)

According to top computing formula, can according to the angle between the required camera of three-dimensional imaging calculate the leading screw slide block the horizontal range that will move, position control through servomotor.

Claims (3)
