Description
Technical field
The utility model relates to a kind of digital camera, especially relates to a kind of to the isostructural improvement of single-lens stereoscopic camera.
Background technology
Digital camera is in the use more and more universal, also replaces the camera of traditional egative film formula simultaneously on function gradually.Digital camera applications especially according to the requirement of military affairs, mapping etc., need be carried out three-dimensional shooting to some objects when the aviation field, finishes and mostly be behind the camera plane photo post-production again for stereoscopic photograph in the past.Chinese patent discloses a kind of multilens digital stereo camera (publication number: CN1441314A), it is made of digital imagery unit, video memory, view finder, synchro-shutter, port, power supply, control chip and flashlamp etc., this camera comprises three digital image-generating units at least, equal intervals is arranged in the horizontal direction, each digital imagery units synchronization exposure document image of synchro-shutter may command; Used the CMOS photoelectric sensor on the digital imagery unit, support fixing and support digital imagery unit can move in the horizontal direction, and is used for regulating the spacing between each image-generating unit; For each digital imagery unit provides a mapping table, the correction data of misregistration image, mapping table is stored in the digital imagery unit, image processor according to mapping table correcting distortion image after, be stored in the storer.A kind of aberration correcting method, be used for proofreading and correct the geometrical aberration of stereoscopic camera or single-lens each image-generating unit of camera set, it comprises, each image-generating unit has a mapping table, writing down each pixel of correcting image (Xn, Yn) position on distorted image (α, β), distorted image f to any solid space shooting, obtain image t after proofreading and correct according to mapping table, and t (Xn, Yn)=f (α, β), if α or β are not integers, and f (α, the available neighbor point pixel value of value β) substitutes, or obtain through approximate processing such as interpolation, each image-generating unit of being proofreaied and correct all is independently cameras.But the camera lens that this camera adopts is a plurality of, and volume is comparatively huge, and assembling is inconvenient.
The utility model content
The utility model technical issues that need to address provide a kind of single-lens stereoscopic camera, and it mainly is that to solve the camera lens that the existing in prior technology camera adopts be a plurality of, and volume is comparatively huge, and assembling is than the technical matters of inconvenience etc.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals:
Single-lens stereoscopic camera of the present utility model, comprise the preceding lens barrel and back lens barrel that link together, be provided with preceding set of contact lenses in the preceding lens barrel, be provided with the back set of contact lenses in the back lens barrel, be provided with blade between preceding lens barrel and the back lens barrel, blade is connected on the motor, it is characterized in that described preceding lens barrel front end is connected with light shield, the front end of light shield inside is connected with first catoptron in the preceding lens barrel of light can being reflexed to of taper, and the first catoptron top is towards preceding lens barrel; Respectively be provided with a light inlet between the both sides inwall of first catoptron and light shield, respectively be connected with second catoptron that light can be reflexed to the first catoptron place on the both sides inwall of light shield; Back lens barrel rear end is connected with shell, and the bottom of enclosure is connected with imageing sensor, imageing sensor connection line plate.The opening part of two light inlets is opened at grade, and light inlet is the passage that tilts of lens barrel forward, make that light enters from light inlet after, before second catoptron, twice reflection of first catoptron enter in the lens barrel.To be projected to imageing sensor behind lens barrel later be on the CCD device to light then, because light is entered by two light inlet places, is similar to the eyes principle of human body, therefore the picture that becomes on imageing sensor is a stereo-picture, wiring board can be by digital processing, with this image output.
As preferably, described light shield section is outwards open tubaeform; In same light inlet, the conical surface of the inwall of light shield, first catoptron and second catoptron are all for be arrangeding in parallel.Light shield integral body in echelon, lens barrel place before the short end of its length is installed in, the end end face that its length is long is a rectangle, the opening of two light inlets is a rectangle.
As preferably, the angle of the conical surface of described first catoptron and preceding lens barrel end face is 45 °.The inwall of second catoptron, light shield also all with preceding lens barrel end face angle at 45
As preferably, the length of described light shield outer end is 25～5000mm.The length of light shield outer end can be set according to the size of captured object.
Therefore, the utlity model has the camera lens that camera adopts and only need one, characteristics such as two light inlets by light shield carry out three-dimensional imaging, and volume is less, and it is comparatively convenient assemble, can be used as ordinary digital camera behind the dismounting light shield, simple and reasonable for structure.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model;
Accompanying drawing 2 is left TV structure synoptic diagram of Fig. 1.
Parts, position and numbering among the figure: preceding lens barrel 1, back lens barrel 2, light shield 3, first catoptron 4, light inlet 5, second catoptron 6, shell 7, imageing sensor 8.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: the single-lens stereoscopic camera of this example as Fig. 1, Fig. 2, has the preceding lens barrel 1 and back lens barrel 2 that link together, be provided with preceding set of contact lenses in the preceding lens barrel 1, be provided with the back set of contact lenses in the back lens barrel 2, be provided with blade between preceding lens barrel 1 and the back lens barrel 2, blade is connected on the motor.Back lens barrel 2 rear ends are connected with airtight shell 7, and the bottom of enclosure is connected with the imageing sensor 8 towards the back set of contact lenses, imageing sensor 8 connection line plates.Preceding lens barrel 1 front end is connected with light shield 3, and light shield 3 integral body are trapezoidal, and its section is outwards open tubaeform.The front end of light shield 3 inside is connected with before light can being reflexed to of taper first catoptron, 4, the first catoptrons, 4 tops in the lens barrel 1 towards preceding lens barrel; Respectively be provided with a light inlet 5 between the both sides inwall of first catoptron 4 and light shield 3, respectively be connected with second catoptron 6 that light can be reflexed to first catoptron, 4 places on the both sides inwall of light shield 3.The angle of the conical surface of first catoptron 4 and preceding lens barrel 1 end face is 45 °, and in same light inlet 5, the conical surface of the inwall of light shield 3, first catoptron 4 and second catoptron 6 are all for be arrangeding in parallel.
