Detailed description of the invention
Describe the present invention below with reference to detailed description of the invention shown in the drawings.But these embodiments are not limiting as the present invention, structure, method or conversion functionally that those of ordinary skill in the art is made according to these embodiments are all contained in protection scope of the present invention.
Please join shown in Fig. 1, for the sectional view of the decoded scan assembly 10 of the present invention, this decoded scan assembly 10 includes: lens bodies 1, Lens assembly 2, sleeve 3 and actuation means 4.Specifically, it is formed with accommodation space in lens bodies 1, this lens bodies 1 is decoded scan assembly 10 neighbor scanning purpose one end, this Lens assembly 2 is assemblied in accommodation space, especially, Lens assembly 2 includes the some eyeglasses being arranged in order along optical axis direction, and the adjustment spacing that cooperates between its eyeglass can reality be focused.
In the present invention, this decoded scan assembly 10 also includes the sleeve 3 being sleeved on lens bodies 1 outer surface and coordinates the actuation means 4 of assembling with sleeve 3, this actuation means 4 can be controlled ground this sleeve 3 relatively and be moved reciprocatingly, especially, this actuation means 4 can selectively link with arbitrary some eyeglasses, thus control focusing, reach spacing more accurately and arrange.Wherein, in the present invention, actuation means 4 includes voice coil motor, it is preferable that selects miniature voice coil motor, thus reduces the volume of whole decoded scan assembly 10, and, miniature voice coil motor energy consumption is smaller.In detail, this miniature voice coil motor load-bearing is less than 2 grams, and the load-bearing of voice coil motor is directly proportional to volume, thus makes its volume reduce as far as possible, in order to the scope of application of this decoded scan assembly 10 is wider, and such as transplantation enters mobile phone, portable scanner etc..
In one embodiment of the present invention, specifically, the outer surface of sleeve 3 is provided with the guide rail line parallel with optical axis direction, and the inner surface of actuation means 4 is provided with the slide rail matched with guide rail line.So that this actuation means 4 drives eyeglass to move back and forth in the direction of the optical axis, thus realize focusing.Certainly, other can realize brake unit 4 and can be controlled the ground embodiment that move reciprocatingly of relative sleeve 3 and be all contained in embodiments of the present invention.
Especially, actuation means 4 also includes coupled eyeglass ring 5, and this actuation means 4 is connected by the outer rim of eyeglass ring 5 with arbitrary some eyeglasses.Be arranged such that voice coil motor can with any of which eyeglass formed can mass motion structure, drive it to move.Preferably, in the present embodiment, being additionally provided with baffle ring 6 and light hurdle 7 in the accommodation space of the lens bodies 1 of this decoded scan assembly 10, this baffle ring 6 and light hurdle 7 can be used for consolidating eyeglass.
As in figure 2 it is shown, be the coding/decoding method of the decoded scan assembly 10 of the present invention, comprise the following steps: accept working signal；Actuation means 4 drives movable lenses to move to the first precalculated position along its optical axis direction, and obtains the first image；Actuation means 4 drives movable lenses to move to the second precalculated position along its optical axis direction, and obtains the second image；Described first image and the second image are carried out definition comparison, and selects piece image to be the most clearly decoded.In detail, after this decoded scan assembly 10 receives working signal, will scan at target pattern to shining by this decoded scan assembly 10, decoded scan assembly 10 is moved by control voice coil motor and focuses, control voice coil motor to move to the most predetermined multiple positions of system, and carry out Image Acquisition respectively, then the image got is compared through process, select the image being wherein best suitable for decoding.Especially, in present embodiment, however it is not limited to the first precalculated position and the second precalculated position, voice coil motor can be set according to demand and adjust being positioned at multiple precalculated position, thus can obtain obtaining the most clear, be best suitable for the image of decoding.
As it is shown on figure 3, be another coding/decoding method of the decoded scan assembly 10 of the present invention, specifically comprise the following steps: accept working signal；Calculate the distance between target and decoded scan assembly 10；Determine the pinpointed focus mated with calculated distance；Calculate with pinpointed focus the matched position of movable lenses time corresponding；Actuation means 4 drives movable lenses to move to matched position along optical axis direction, and obtains image and be decoded.Specifically, after this decoded scan assembly 10 obtains working signal, request is sent to range finding module, range finding module is by measuring, obtaining the distance scanning target pattern with this decoded scan assembly 10, decoded scan assembly 10, according to the target range recorded, calculates pinpointed focus and the desired location of the linked eyeglass of voice coil motor, finally by controlling the optimum position that voice coil motor moves to calculate, carry out Image Acquisition and decode.
Lens assembly 2 is decoupled by the present invention, utilizes voice coil motor to drive any of which eyeglass of Lens assembly 2 to move and realizes focusing, and it not only achieves the purpose of focusing, simultaneously, only drive single lens, reduce the volume of this decoded scan assembly 10, and reduce the energy consumption of voice coil motor.
