Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the disclosure. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.

In the description of the embodiments of the present disclosure, the term "and/or" is only one kind of association relationship describing an associated object, and means that there may be three kinds of relationships, for example, a and/or B, and may mean: a exists alone, A and B exist simultaneously, and B exists alone.

In the description of the embodiments of the present disclosure, unless otherwise explicitly specified or limited, the terms "mounted," "connected," "fixed," and the like are to be construed broadly, e.g., as meaning fixedly connected, detachably connected, or integrally formed; mechanical connection or electrical connection is also possible; either directly or indirectly through intervening media, either internally or in any other relationship. Specific meanings of the above terms in the embodiments of the present disclosure can be understood by those of ordinary skill in the art according to specific situations.

In the related art, taking an image capturing apparatus as an example, the image capturing apparatus may have a mounting arm, the mounting arm may be provided with a camera assembly for capturing an image of a document to be captured and two lasers for emitting laser beams, and each laser may be mounted perpendicular to the mounting arm, so that the laser beam generated by the laser can be directly projected onto the document to be captured.

However, in the related art, in order to achieve flattening of the data to be photographed, strict requirements are imposed on the positions of the laser beams generated by the two lasers, and therefore, when the image acquisition device is shipped from a factory, the positions of the lasers need to be calibrated, so that the laser beams irradiated to the data to be photographed can meet the requirements.

However, the position of the laser needs to be adjusted manually in the calibration process, so that the calibration process is high in cost, time-consuming and labor-consuming, low in positioning accuracy, poor in consistency of batch production, and difficult to ensure the product quality. In addition, since the structure of the laser is complicated, in order to mount the laser at a proper position, the difficulty of the mold design of the mounting structure of the laser is increased.

In addition, since the laser has a large size in the laser beam emitting direction, after the laser is mounted to the mounting arm, the thickness of the mounting arm is thick, which in turn causes the entire image pickup apparatus to be bulky.

In order to solve at least one of the above problems, an embodiment of the present disclosure provides a laser device and an image capturing apparatus, where a laser component and a light processing component are provided, the laser component is configured to emit a plurality of laser beams, the light processing component includes a plurality of light processing members, each light processing member is correspondingly disposed on a propagation path of one laser beam, and the light processing member is configured to change a propagation direction of the corresponding laser beam, so that the laser beam is projected to a document to be photographed. Embodiments of the present disclosure are explained below with reference to the drawings.

FIG. 1 is a schematic diagram illustrating operation of an image acquisition device according to an exemplary embodiment of the present disclosure; FIG. 2 is a schematic diagram of the operation of the laser device within the image capture apparatus of FIG. 1; FIG. 3 is a schematic diagram of the laser apparatus of FIG. 2; fig. 4 is a top view illustrating a laser apparatus according to an exemplary embodiment of the present disclosure; fig. 5 is a side view illustrating a laser apparatus according to an exemplary embodiment of the present disclosure. In order to distinguish the laser beams in fig. 5, two laser beams are shown by a solid line and a broken line, respectively.

Referring to fig. 1 to fig. 5, the present embodiment provides a laser apparatus 100, where the laser apparatus 100 may be used in an apparatus for shooting and acquiring a book or a magazine waiting to be shot with a shooting document 500, the apparatus may be an image acquisition apparatus 10 such as a high-speed camera or an intelligent reader, or the apparatus may also be another apparatus. For convenience of description, the laser device 100 is applied to the image capturing apparatus 10, and the laser device 100 may be disposed on the mounting arm 300 of the image capturing apparatus 10.

The laser apparatus 100 includes: the laser device 110 is used for emitting a plurality of laser beams 111, the optical processing device 120 includes a plurality of optical processing members 121, each optical processing member 121 is correspondingly disposed on a propagation path of one laser beam 111, the optical processing member 121 is used for changing the propagation direction of the corresponding laser beam 111, so that the laser beam 111 is projected to the data 500 to be photographed, and a reference light 112 is formed on the surface of the data 500 to be photographed, and a plurality of reference lights 112 formed by the plurality of laser beams 111 are disposed at intervals.

The number of the laser beams 111 emitted by the laser assembly 110 may be 2, 3, 4 or more. The laser assembly 110 may have a variety of configurations, for example, the laser assembly 110 may include a plurality of lasers 113, each laser 113 operable to emit a laser beam 111. For another example, the laser assembly 110 may have only one laser light source, and the beam emitted from the laser light source may be divided into a plurality of laser beams 111 by the light splitting structure, which may be specifically set as required.

The light processing assembly 120 may include a plurality of light processing members 121, and the number of the light processing members 121 may be the same as the number of the laser beams 111, i.e., one light processing member 121 may be disposed corresponding to each laser beam 111. Each of the light processing members 121 may be disposed on a propagation path of the laser beam 111 so that the laser beam 111 may be irradiated onto the light processing member 121.

It is understood that the emitting direction of each laser beam 111 is the direction of the laser beam emitted from the laser assembly 110, and as shown in fig. 4, each laser beam 111 forms a fan-shaped plane in the propagation process, and the axial direction of the fan-shaped plane is the emitting direction 114 of the laser beam 111. The light handling member 121 may be disposed at a position in the emission direction 114 such that the laser beam 111 may be projected onto the light handling member 121.

In addition, the optical processing member 121 may be configured to change the propagation direction of the laser beam 111, and it is understood that, as shown in fig. 5, after the laser beam 111 is emitted, it will be emitted along the emission direction 114, after passing through the optical processing member 121, the laser beam 111 will be emitted out deviating from the emission direction 114, and by setting the deviation angle of the laser beam 111, the laser beam 111 passing through the optical processing member 121 can be emitted to the document 500 to be photographed.

The structure of the light processing member 121 may be various, and for example, it may be a structure that can change the propagation direction of the laser beam 111 by using a reflection principle, a refraction principle, a diffraction principle, or the like.

With reference to fig. 2, two laser beams 111 are shown, and the two laser beams 111 are projected onto the to-be-photographed material 500 after passing through the optical processing assembly 120, so that 2 reference light beams 112 are formed on the surface of the to-be-photographed material 500, and the two reference light beams 112 are arranged at intervals.

The reference beam 112 is a light spot formed on the surface of the data 500 to be photographed by the laser beam 111. The plurality of reference light beams 112 formed by the plurality of laser beams 111 may be arranged at intervals in the same direction. It is understood that if the plurality of laser beams 111 are irradiated onto the same plane, the plurality of reference light beams 112 may be arranged in parallel and at intervals, as shown in fig. 2, the document 500 to be photographed is a paper, that is, the surface of the document 500 to be photographed is a plane, and at this time, the plurality of reference light beams 112 may be arranged in parallel and at intervals along the same direction. If the surface of the book or the like to be photographed 500 is a curved surface, the reference light 112 may have a curved structure crossing the curved surface, and the plurality of reference light 112 may be spaced along the same direction, and the reference light 112 does not intersect with each other.

If the document 500 to be photographed is an unfolded book or the like, the image of the document 500 to be photographed with the reference light 112 is acquired, so that the subsequent image processing can be assisted, the image can be flattened, and the characters in the image can be recognized. The specific image processing method may be an image flattening algorithm commonly used in the related art, and is not described herein again.

It can be understood that when calibrating the laser device 100, the calibration can be realized by adjusting the mounting position of the optical processing assembly 120, because the structure of the optical processing assembly 120 is simpler than that of the laser assembly 110, the position adjustment is easier, the accuracy of the position adjustment is high, the calibration difficulty is small, the batch production consistency is good, the product quality can be ensured, less human resources can be consumed, and the production cost can be reduced.

Moreover, since the light processing member can change the propagation direction of the corresponding laser beam, the installation direction of the laser assembly can be changed, for example, a laser device vertically installed relative to the installation arm in the related art is changed to the laser assembly 110 installed in parallel to the installation arm 300, so that the installation space of the image capturing device can be reasonably and flexibly utilized, the size of the installation arm 300 in the thickness direction H can be reduced, and the volume of the installed image capturing device can be further reduced.

In addition, since the position of the reference light 112 can be adjusted by the light processing assembly 120, the requirement for the installation position of the laser assembly 110 is reduced, so that the difficulty of the mold design of the installation structure thereof can be simplified.

In some embodiments, the laser beam 111 is a line beam, i.e., the laser beam 111, if projected directly onto a plane, will form a line-shaped spot.

With continued reference to fig. 3-5, in some embodiments, the laser assembly 110 includes a plurality of lasers 113, each laser 113 is configured to emit a laser beam 111, and each light processing element 121 is disposed on the light exit axis 114 of a corresponding laser 113.

The light exit axis 114 of the laser 113 may coincide with the emitting direction of the laser beam 111 emitted by the laser 113, and each laser 113 may also be a line laser to emit a line beam. By using a plurality of lasers 113 to emit a plurality of laser beams 111, the structure of the laser assembly 110 can be simplified, reducing costs.

As shown in fig. 4, in some embodiments, the light-exiting axes 114 of the lasers 113 are parallel to each other, and the arrangement of the lasers 113 is regular, so that the installation space can be further saved.

In some embodiments, the plurality of lasers 113 are arranged in a direction perpendicular to the light exit axis 114. For example, the plurality of lasers 113 may be arranged in the width direction W in fig. 1, so that the width space of the mounting arm 300 can be utilized rationally, and the dimension in the thickness direction H thereof can be further reduced.

It is understood that, in the above embodiments, the plurality of lasers 113 may be arranged in parallel along the width direction W of the mounting arm 300, and in other embodiments, the plurality of light-emitting axes 114 of the plurality of lasers 113 are located on the same straight line, that is, the plurality of lasers 113 may be arranged in series along the direction of the light-emitting axis 114 of a certain laser 113, or the reference light 112 may be formed on the surface of the document 500 to be photographed at intervals.

With continued reference to fig. 4, in some embodiments, each light management member 121 is spaced from the corresponding laser 113 by a predetermined distance such that the laser beam 111 emitted by the laser 113 is entirely projected onto the light management member 113.

The distance L between each light processing member 121 and the corresponding laser 113 may be a distance from the light exit surface of the laser 113 to an intersection point of the light exit axis 114 of the laser 113 and the light processing member 121.

It can be understood that by reasonably setting the preset size of the distance L, the laser beam 111 can be fully projected to the optical processing member 113, that is, all the laser beam 111 can be deflected, and there is no phenomenon that part of the laser beam 111 is not processed by the optical processing member 121, so that the utilization rate of the laser beam 111 can be improved, and the size of the optical processing member 121 can be reduced as much as possible, thereby reducing the installation volume of the laser device 100.

In addition, each of the light processing members 121 may have a different preset size from the corresponding laser 113, or a plurality of preset sizes of the light processing members 121 may be the same, so that the installation volume of the laser device 100 may be further reduced.

On the basis of the above embodiment, the light processing member 121 includes the reflection surface 123 for reflecting the laser beam 111.

The reflecting surface 123 may be a reflective coating disposed on the light processing member 121, and after the laser beam 111 is irradiated onto the reflecting surface 123, the laser beam 111 may be reflected, thereby changing its propagation direction. The reflecting surface 123 has a simple structure and requires less shape for the light processing member 121.

In some embodiments, as shown in fig. 5, in the plurality of reflection surfaces 123 of the plurality of light processing members 121, each reflection surface 123 is disposed to be inclined with respect to the remaining reflection surfaces 123, that is, the plurality of reflection surfaces 123 may be disposed not parallel to each other, and may have a certain inclination angle therebetween, so that in the case where the plurality of light processing members 121 are arranged in parallel along the width direction W, the plurality of laser beams 111 may have different deflection angles by setting different inclination angles, and further, the reference light beams 112 may be formed on the surface of the material 500 to be photographed and spaced from each other.

As a specific implementation manner of the light processing member 121, the light processing member 121 may include a reflector 122, the reflection surface 123 is disposed on a side surface of the reflector 122, and the reflector 122 has a uniform and thin thickness, so that the light processing member is convenient to install and has low cost.

In addition, the light processing member 121 can change the propagation direction of the laser beam 111 by using the principle of reflection. In other embodiments, the light processing member 121 may further include a refraction member for refracting the laser beam 111, and the refraction member may change the propagation direction of the laser beam 111 by using the principle of refraction of light.

By setting the installation angle of each refraction member, the incident angle of the laser beam 111 can be changed, and then the exit angle of the laser beam 111 exiting the refraction member can be controlled, so that the mutually spaced reference light rays 112 can be conveniently formed. Alternatively, by selecting different materials of the refractive member, the deflection angle of the laser beam 111 exiting the light processing member 121 can be changed to form the reference light rays 112 spaced apart from each other according to the refractive index difference between the different materials with the same incident angle.

In some embodiments, the laser apparatus 100 further comprises: and a plurality of adjusting members 124, wherein each adjusting member 124 is connected to one of the light processing members 121, and the adjusting members 124 are used for driving the light processing members 121 to rotate relative to the laser assembly 110 so as to change the incidence angle of the laser beam 111 to the light processing members 121.

The adjusting member 124 can be used for factory calibration, which facilitates workers to adjust the propagation direction of the laser beam 111 passing through the light processing assembly 120, and the type of the adjusting member 124 can be various, for example, the light processing member 121 can be rotatably mounted on the mounting arm 300 through a rotating shaft, and the mounting angle of the light processing member 121 can be changed by adjusting the rotating angle of the rotating shaft, so as to change the incident angle of the laser beam 111.

Alternatively, the light processing member 121 may be fixed to the mounting arm 300 by a fixing member such as a screw, and when adjustment is required, the screw may be loosened so that the light processing member 121 may rotate relative to the laser assembly 110, and when adjusted to a proper position, the screw may be tightened to fix the light processing member 121.

The calibration of the laser device 100 can be facilitated by arranging the adjusting piece 124, the production cost is reduced, and the trouble and the labor are saved.

With continued reference to fig. 1 and 2, the present embodiment also provides an image pickup apparatus 10 including: the laser device comprises a main body 200, a mounting arm 300 and a laser device 100, wherein the main body 200 is provided with a mounting surface 210, the mounting surface 210 can be used for being in contact with a working table, the mounting arm 300 extends out of the main body 200, and the laser device 100 is arranged on one side, facing the mounting surface 210, of the mounting arm 300.

It is understood that the document 500 to be photographed may be placed on the work table. The document 500 to be photographed may be a document having characters or figures and needing to be photographed, such as paper, books, magazines, packing boxes, and the like.

The mounting arm 300 may extend outward from the main body 200, and the laser device 100 may be disposed on a side of the mounting arm 300 facing the mounting surface 210, that is, the laser device 100 may be disposed facing the document 500 to be photographed, so as to conveniently project the laser beam 111 onto the document 500 to be photographed.

The structure and function of the laser device 100 are the same as those of the above embodiments, and reference may be made to the above embodiments for details, which are not described herein again.

When the laser device 100 is calibrated, the calibration can be realized by adjusting the installation position of the optical processing assembly 120, because the structure of the optical processing assembly 120 is simpler than that of the laser assembly 110, the position adjustment is easier, the accuracy of the position adjustment is high, the calibration difficulty is small, the batch production consistency is good, the product quality can be ensured, less human resources can be consumed, and the production cost is reduced.

Moreover, since the light processing member 121 can change the propagation direction of the corresponding laser beam 111, the installation direction of the laser module 110 can be changed, for example, a laser installed perpendicularly to the installation arm in the related art is changed to the laser module 110 installed parallel to the installation arm 300, so that the installation space of the image capturing apparatus 10 can be reasonably and flexibly utilized, the size of the installation arm in the thickness direction H can be reduced, and the volume of the installed image capturing apparatus 10 can be reduced.
