The multi-view scanning structure shown in fig. 1 is used for scanning of a scanner, and comprises a light angle adjusting component and a linear module 3, wherein the linear module is a product in the prior art, and the multi-view scanning structure is a linear transmission device and mainly has two modes, wherein: one is composed of ball screw and linear guide track, and the other is composed of synchronous belt and synchronous belt wheel. The linear module 3 is movably provided with a lens 2, a sensor 1 is optically connected above the lens 2, the sensor 1 can be arranged on the linear module or at other places of the scanner, and the sensor, preferably a linear image sensor, is optically connected with the lens 2. The information of sensor 1 collection can be fed back to the controller in the scanner, and camera lens 2 also can set up with the camera lens integral type as for the sensor below, wherein:
a light angle adjusting assembly for adjustably transmitting the scanning light of the scanned object to the lens 2, preferably, the scanning light is rotatably transmitted to the lens 2, and the light angle adjusting assembly, for example, a rotatable mirror assembly, may include a fixed mirror and a rotatable mirror for transmitting the scanning light of the scanned object to the fixed mirror;
the sensor 1 can receive the scanning light of the scanned piece passing through the lens 2, transmits light data to a controller in the scanner when the lens 2 receives the light, and controls the lens 2 to move on the linear module 3 when the controller receives the light data, so that the length of a light path from the scanning light of the scanned piece to the lens 2 is unchanged. The scanner controller calculates the change of the optical path length for changing the visual angle, and the optical path length from the scanning piece to the lens 2 is unchanged (the transmission paths of the scanning optical paths at different angles are inconsistent and are realized by up-down movement of the lens 2, and the upper and lower references use the position of the image 1 as the reference) by adjusting the height of the lens 2 on the linear module 3, so that the image sensor can obtain the same clear image at different visual angles, and the multi-visual-angle scanning of the scanner is realized. The multi-view scanning can realize special texture scanning of materials, and planar vivid stereoscopic images can be manufactured through the multi-view scanning images, so that the image sensor can obtain the same clear images at different viewing angles.
As an alternative embodiment, as shown in fig. 2, the light angle adjusting assembly includes a base frame 4, and a fixed mirror 41 and a rotatable mirror assembly are mounted on the base frame 4, wherein:
one end of the base frame 4 is connected with the linear module 3, a fixed reflector 41 is arranged on the base frame 4 and close to the linear module 3, the fixed reflector 41 corresponds to the lens 2, and scanning light of a scanned piece enters the lens;
and a rotatable reflector component is arranged on the base frame 4 and far away from the adjacent linear module 3, and during scanning, the rotatable reflector component transmits scanning light rays of scanned pieces with different angles to the fixed reflector.
As an alternative embodiment, the rotatable mirror assembly includes a rotatable mirror 42 and a recliner motor 43 coupled to the rotatable mirror, wherein:
the angle adjusting motor 43, as a power output member, can drive the rotatable mirror to rotate.
The working principle is as follows: as shown in fig. 3 and 4, the lens 2 is mounted on the slider of the linear module 3, two sets of reflectors are mounted in front of the lens 2, one set near the lens is a fixed reflector 41, only light with a fixed angle can enter the lens 2, one set near the scanned document is a rotatable reflector 42, a tilt-adjusting motor 43 is mounted on the rotatable reflector, and the angle of the rotatable reflector 42 is changed by the rotation of the tilt-adjusting motor 43, so that light with different viewing angles on the scanned document enters the lens 2. Each angular position of the rotatable mirror 42 corresponds to a viewing angle of light entering the lens 2. The image sensor 1 is installed behind the lens 2, and the image displayed by the lens 2 is collected.
Alternatively, the rotatable mirror 42 is mounted at an acute angle to the horizontal. The angle of the rotatable mirror to the horizontal is preferably 45 degrees. When the angle between the rotatable reflective mirror 42 and the horizontal plane is 45 degrees, the optical path length is shortest, for example, the optical path length between the rotatable reflective mirror 42 and the document to be scanned is denoted by h, and the angle between the rotatable reflective mirror 42 and the horizontal plane is 45 degrees, which is a rotation angle α degrees, the optical path length between the rotatable reflective mirror 42 and the document to be scanned is h ', as shown in fig. 4, for example, when the rotation angle is changed by 2 degrees, the angle between the rotatable reflective mirror 42 and the horizontal plane is 47 or 43 degrees, h ' can be calculated by a geometric formula, then, the change s of the optical path length is increased by h ' -h, s is the movement displacement of the lens 2 on the linear module, and the controller controls the lens 2 to move on the linear module, thereby realizing the multi-view scanning function.
