Description

Stereo raster camera

The utility model relates to a kind of camera of taking solid, material object, especially can move shooting, no matter the object distance distance can both be taken the grating stereo video camera of the good image of stereoeffect.

At present, known grating stereo video camera, body does not have rotating mechanism inactive: calculate that from the data of existing camera advertisement existing camera is when the 1m object distance, the angle between the start-stop axis is 4 °, during 2m be 2 °, be 1 ° during 4m, angle is more little, and stereoeffect is weak more, and need special camera lens, wide 70mm.

The purpose of this utility model is the defective in view of prior art, provides the angle between a kind of start-stop axis big, the grating stereo video camera that stereoeffect is good.

The purpose of this utility model is achieved in that

The utility model is by casing, at the bottom of expansion box, camera bellows, the case, camera lens, roll adjustment screw, the focusing screw is formed, it is characterized in that: casing is installed on the guide rail, guide rail has two, wherein one is tooth bar, and motor and chassis connect together, and the engagement of the wheel and rack on the motor, the film holder swivel mount is installed on the casing, film holder is installed on the film holder swivel mount, and the shutter release on the egative film swivel mount base plate is linear brush, and its length is adjustable.

Be connected with a lever on the swivel mount base plate, a vertical rod arranged at the bottom of the case, also have two slots, one is transverse holes, another is vertical hole, and a vertical rod and a horizontal slot are arranged on the chassis, and the back side, chassis is equipped with sector gear, its afterbody has groove, slide bar is arranged in the groove, two in-line gears also are installed on the chassis, gear and sector gear engagement, another wheel and rack engagement, vertical rod is the fulcrum of lever.When the chassis orbits, gear driven casing rotation on the chassis, lever drives the film holder rotation simultaneously in the casing, its axis intersects at object main body (being the center of circle) all the time in the casing rotary course, adopt the concentric rotation shooting of wide-angle (to regulate with gear, make the start-stop axis angle of any distance be 10 °), film holder then rotates continuously according to the going into of light beam, reflection characteristic, to guarantee that image is not only separately but also continuous.Shooting angle is 10 °, its 10 ° of strokes of different object distances do not wait, during design, machine bottom bar 13 both can be swung, and can move forward and backward again, and swing far away more is big more from the sectional wheel center of circle, the body that guarantees to be in operation is walked 10 °, it is for 10 ° to realize by the operation stroke that the while photograph axis also changes 10 ° of bodies commentaries on classics, and axis changes 10 °, then is that the swing of rod 13 realizes.

Below in conjunction with accompanying drawing the utility model is further specified:

Fig. 1 is a casing, film holder swivel mount, the exploded view of film holder.

Fig. 2 is machine shape figure.

At the bottom of Fig. 3 is running chassis case, swivel mount base plate exploded view.

Fig. 4 is the chassis back view.

Among the figure, the 1st, casing, 1-1 are expansion boxs, 1-2 is a camera bellows, the 2nd, and film holder swivel mount, the 3rd, film holder, the 4th, camera lens, the 5th, roll adjustment screw, the 6th, focusing screw, the 7th, motor, the 8th, guide rail, the 9th, swivel mount base plate, the 10th, lever, the 11st, shutter release, the 12nd, vertical slot, the 13rd, slide bar, the 14th, horizontal slot, the 15th, at the bottom of the case, the 16th, vertical rod, the 17th, vertical rod, the 18th, chassis, the 19th, gear, the 20th, with 19 coaxial gears, the 21st, sector gear, the 22nd, the groove that sector gear is opened later, the 23rd, with the gear of motor coaxle, the 24th, tooth bar, the 25th, horizontal slot.

Fig. 1,2 mediellas folder swivel mount 2 is installed on the casing 1, film holder 3 is installed on the film holder swivel mount, shutter release 11 on the egative film swivel mount base plate is brushes, the linear adjustable long weak point of transferring, big pitch is transferred long, and little pitch is transferred weak point, its length is consistent with used pitch, and the rotational value of negative rack becomes with the pitch of lenticular lenses.

Among Fig. 2, casing 1 is installed on the guide rail 8, and guide rail 8 has two, and wherein one is tooth bar 24, and motor 7 connects together with chassis 18, and gear on the motor 23 and tooth bar 24 engagements.Casing comprises also at the bottom of expansion box 1-1 and the camera bellows 1-2 case etc. that casing has camera lens 4 outward, roll adjustment screw 5, focusing screw 6.

Fig. 3 is connected with a lever 10 on the swivel mount base plate in 4.A vertical rod 16 is arranged on 15 at the bottom of the case, two slots are arranged, one is transverse holes 14, and another is vertical hole 12.One vertical rod 17 and a horizontal slot 25 are arranged on the chassis 18, the back side, chassis is equipped with sector gear 21, its afterbody has groove 22, slide bar 13 is arranged in the groove, in-line gears 19 and 20 also are installed on the scale, gear 19 and sector gear 21 engagements, gear 20 and tooth bar 24 engagements, vertical rod 16 is fulcrums of lever 10.

Motor driven gear 23 rotations, gear 23 drives tooth bar 24, tooth bar 24 driven gears 20,19, gear 19 drives sector gear 21, sector gear 21 drives slide bar 13 swings, longitudinally oblong aperture 12 is slided simultaneously, the angle that its swinging distance is ordered to O is the rotation angle of body, and bar 13 promotes the casing rotation, and the vertical rod on the casing in service 17 simultaneously promotes lever 10 swings, vertical rod 16 is the fulcrum of lever 10, one end of lever 10 is connected with at the bottom of the swivel mount, thereby along with lever 10 swings, the film holder swivel mount rotates.Controlling 10 ° of operations is the swings that utilize 13 slide bars, and by shutter release, 10 ° of starting point energisings, the terminal point outage realizes.

The utility model is simple in structure, no matter the object distance distance can both be taken the good image of stereoeffect, is applicable to various camera lens.
