Abstract

The utility model relates to a stereo digital camera, which is used for recording stereo images. The camera is composed of two sets of digital cameras with identical specifications. The distance between two parallel taking lenses is from 6 to 15CM. The two parallel taking lenses respectively aim to a target from 1 M to 5 M. Parameters of focusing, zooming, sensitizing, etc. of the digital camera are implemented and controlled by a set of control circuits. A shutter connecting lines are connected in parallel. A left image and a right image which are photographed are grouped by a computer, and is alternately displayed on a screen of the computer by the frequency which exceeds visual persistence frequency of human eyes. The utility model uses a 3D electric liquid crystal glasses which is synchronized with the computer to control the view ray. Consequently, the left eye and the right eye respectively correspond to the left image and the right image. The utility model has the effect that the two eyes directly watch the photographing scene. The users can distinguish the difference of the front and rear distance by synthesize of the brain, and can feel the stereoscopic effect that the users stay in the actual scene.

Description

Stereo digital camera

Technical field the utility model belongs to field of photoelectric technology, is a kind of device that is used for obtaining the 3-D digital picture information.

The present 3-D digital visualization techniques of background technology is very ripe, mix 3D electronic liquid crystal glasses, just can on computer display screen, show stereoscopic image true to nature, but the image source generally is confined to the making that computer software imitates at present, mainly is used on some Games Softwares; It reproduces the technological requirement complexity stereoscopic camera of conventional film record, costs an arm and a leg.Although the grid of stereotome has been done very carefully at present, still to lose the information over half of a width of cloth picture eventually, and watched the visual angle that bigger restriction is also arranged, the effect of hanging on the wall is also desirable not to the utmost.

Summary of the invention is in order further to advance the application of stereoscopic image, and the utility model provides a kind of stereo digital camera, and it is actually parallel and produce by two digital cameras together.With it once take simultaneously have the human eye parallax about two photos, this two photos is placed on the computer, right by the computer software group, frequency Alternation Display to persist on computer screen above human eye vision, control sight line by the 3D electronic liquid crystal glasses that cooperate with it again, about making two watch respectively corresponding about two photos, its effect is as two eyes direct viewing scenes being shot, in synthesizing down of brain, can tell the difference of longitudinal separation, experience stereoeffect on the spot in person.Compare with existing stereoscopic photograph, it does not have stopping of grid, has reproduced whole images of stereoscopic picture plane fully, does not have the restriction of viewing angle yet.Main is that it is simple, need not to spend a lot of money to go very rare stereoscopic photograph to take and make stereoscopic photograph, the own all processes that just can finish the shooting and the reproduction of exploded view easily as the shop.

The beneficial effects of the utility model are that along with popularizing of computer and digital camera, exploded view can be walked close to people's life easily.The picture record mode also can be advanced more, changes the incomplete situation of a shot record image in the past, becomes the one-eyed eyes that are, makes image reconstruction press close to people's sense organ more.

Description of drawings Fig. 1 is the stereo digital camera structural drawing, and wherein 1 is two independent digital camera external members.The 2nd, shutter release button goes between also together with two shutter releases that overlap digital camera.3 is two digital camera lens.4 is the spacings between two camera lenses.The 5th, battery.The 6th, with the socket of pc connection.The 7th, three-dimensional selector switch.Switch divides three retainings, and the centre is a stereoscopic shooting, the selection when both sides are respectively independent use left and right sides camera.The shared starting switch of two digital camera external members, pc connection socket etc. all thus switch distribute.

Fig. 2 is simple stereo digital camera outward appearance.

Fig. 3 is a parallax perspective schematic diagram, and 1 is preceding in kind, and 2 backs are in kind, 3 left camera lenses, the projected position on screen in kind before the 4 right camera lenses, 5 left pictures, projected position on screen in kind before the 6 right pictures, projected position on screen in kind behind the 7 left pictures, the projected position on screen in kind behind the 8 right pictures, the angle at 9 liang of alignment lens screen places, 10 screens, 11 spacings, 12 left pictures, 13 right pictures.

This stereo digital camera of embodiment is actually by the digital camera (1) of two cover same sizes to be formed, and two pick-up lenss (3) are parallel at a distance of the 6-15 centimetre, and its spacing (4) changes with lens focus, and focal length increases spacing and increases.Two pick-up lenss are aimed at the target of 1-5 rice, and institute looks the angle (schematic diagram 9) of target and watches screen distance adjustable, generally adjust between the 1-4 degree, if watch with projector, can transfer to 1 and spend.Two shutter lines are together in parallel, and are controlled by a button (2).If a three-dimensional selector switch (7), the shared starting switch of two digital cameras, pc connection socket (6) etc. all thus switch distribute.Parameters such as the focusing of two digital cameras, zoom, sensitization are implemented control by a cover control circuit, guarantee the unanimity of two photos.

Claims

A kind of stereo digital camera that writes down effect of three-dimensional image, it is characterized in that: get two identical digital camera devices,, at a distance of the spacing of 6-15 centimetre, target, parallel the fitting together of aiming at 1-5 rice two shutter release button lines are together in parallel by two pick-up lenss.
