Description

The adjustment device of twin-lens full shot imaging center

Technical field

The utility model relates to a kind of technology in optical device field, specifically a kind of twin-lens full shot imaging The adjustment device at center.

Background technique

The full shot constituted for the twin-lens that is placed back to back, in which: each camera lens have more than 180 ° Field of view angle, shooting obtain two pictures, obtain panoramic pictures by the splicing that algorithm carries out two pictures.In order to be conducive to algorithm Splicing, two pictures are preferably symmetrical in space, that is, require the center of picture on same axis, And it is located at the two sides of axis；In order to reach such effect, the imaging center of two camera lenses needs on same axis, The optical axis of i.e. two camera lenses needs to guarantee very high concentricity.

The current twin-lens full shot being placed back to back with lower component mainly by being constituted: two be placed back to back Camera lens, the pedestal being threadedly coupled respectively with two camera lenses, and the connector of two camera lenses of connection.Using such structure side The concentricity of formula, camera lens can not adjust, and there is the optical axises of two camera lenses not to be overlapped, and the feature of imaging center offset gives image Stitching algorithm brings very big difficulty.In order to meet concentricity requirement as far as possible, the method for improving machining accuracy can only be relied on, Common working ability is generally difficult to realize higher coaxial accuracy requirement, and the higher coaxial accuracy met the requirements High cost is needed, is not the method that can be used.

Utility model content

The utility model cannot achieve the imaging center pair for the twin-lens full shot being placed back to back for the prior art It the defects of standard causes the picture of shooting to differ greatly, and when panoramic mosaic algorithm process is difficult to handle, the picture distortion of splicing, mentions A kind of adjustment device of twin-lens full shot imaging center out can adjust the alignment of lens imaging center, it is ensured that the figure of shooting Piece difference is smaller, greatly reduces the difficulty that hair is calculated in splicing, and obtained picture can smoothly splice, avoid being distorted.

The utility model is achieved through the following technical solutions:

The utility model includes: to be symmetrically disposed on a pair of of adjustment block of link block two sides and be set in adjustment block to be used for The pedestal of fixed lens, in which: adjustment block is flexibly connected with link block, and pedestal is fixedly connected with adjustment block.

The camera lens respectively it is back-to-back be set to it is described adjustment device two sides and its optical axis on same axis

The link block is frame structure, and two sides are parallel to each other and are symmetrically arranged with fixed through-hole.

The adjustment block is plank frame, including at least two planes parallel to each other, be respectively used to firm banking with And it is flexibly connected link block.

The plane is equipped with adjusting hole, and the through-hole for being aligned on link block carries out precise fine-adjustment.

Specific embodiment

As shown in Figure 1, including in the present embodiment: the first camera lens 1 and the second camera lens 2 that are placed back to back, respectively with first First base 3 and second base 4 that camera lens 1 and the second camera lens 2 are fixedly connected, the first adjustment block 5 being connect with first base 3 and The second adjustment block 6 being connect with second base 4 and the link block 7 being flexibly connected with the first adjustment block 5 and second adjustment block 6.

The optical specification and mechanism size of first camera lens 1 and the second camera lens 2 are close, preferably use same rule Lattice are further preferably fish eye lens, and field angle is all larger than 180 °, i.e. field angle constitutes 360 ° of viewfinder range.

The optical axis of first camera lens 1 and the second camera lens 2 is on same axis.

The first adjustment block 5 has at least two planes, and the first plane 8 and the second plane 9 are parallel to each other, in which: First plane 8 contacts fixation with first base 3；The first adjustment block 5 has at least two threaded holes and at least three adjusting holes 14, Wherein: threaded hole is connected by screw to first base 3.

The second adjustment block 6 has at least two planes, and third plane 10 and fourth plane 11 are parallel to each other, In: third plane 10 contacts fixation with first base 3；Second adjustment block 6 has at least two threaded holes and at least three adjustment Hole 14, in which: threaded hole is connected by screw to second base 4.

The link block 7 has at least two planes, and the 5th plane 12 and the 6th plane 13 are parallel to each other, in which: the Five planes 12 and the second plane 9 of the first adjustment block 5 pass through through-hole 15 by screw realization distance fine regulation, the 6th plane 13 and the The fourth plane 11 of two adjustment blocks 6 passes through through-hole 15 and realizes distance fine regulation by screw.
