Description

Technical Field

[0001] The utility model relates to the technical field of image scanning equipment, in particular to a multi-angle rapid scanning component. Background Art

[0002] Currently, an image scanning device is a device for scanning an original image (such as a painting or a picture) and converting the original image into digital data.

[0003] With the development of information technology, small-format (below A0 size) paper documents have been digitized and electronically stored and processed by scanners and other equipment. However, for large-format (above A0 size) paper documents in some special demand areas, such as large-format image scanning and acquisition equipment for large-format paper documents such as oil paintings, there are the following problems: 1. Because oil paintings are made of ink and there are uneven ink dots on their surface, the scanning components in the existing large-format image scanning and acquisition equipment need to scan back and forth multiple times at different angles to fully record all the concave and convex feature information of the scanned area of ​​the large-format oil painting, which greatly reduces the efficiency of information scanning and acquisition in actual use. Utility Model Content

[0004] In order to solve the deficiencies in the prior art, the utility model provides a multi-angle rapid scanning component.

[0005] The technical solution of the utility model is:

[0006] The utility model provides a multi-angle rapid scanning component, comprising a frame, a collection device, a light source, a reflector and a mask sleeved on the outer side of the frame; the bottom end of the frame can be connected to an external scanning platform, the collection device is fixed on the top surface of the frame, there are at least eight light sources and they are respectively fixed on the four inner side surfaces of the frame from bottom to top, and a reflector is fixed at the lower end of each of the four inner side surfaces of the frame.

[0007] Furthermore, the light sources on opposite sides of the frame are symmetrically arranged, and the light sources between adjacent sides of the frame are staggeredly distributed.

[0008] Furthermore, the light source includes a lamp and a light guide plate, the light guide plate is fixedly arranged on the inner side of the frame by a bracket, and the lamp is arranged above the light guide plate and its irradiation end is oriented in the same direction as the light guide plate.

[0009] The beneficial effects achieved by the utility model are:

[0010] The eight light sources in the utility model can be turned on individually or all at the same time. The eight light sources tilted around the frame and the corresponding reflectors cooperate to realize sequential scanning and acquisition of color images and high and low shadow image information in different directions of the image acquisition point in front, back, left and right of the scanned image, so that the utility model only needs to scan once at a uniform speed to complete the acquisition of color images and high and low shadow image information of the image acquisition point, thereby improving the efficiency and accuracy of scanning and acquiring information.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0017] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection;

[0018] It can be directly connected, or indirectly connected through an intermediate medium, or it can be internal communication between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0019] like Figure 1-3As shown, a multi-angle fast scanning component provided by the utility model includes a frame 21, a collection device 22, a light source 23, a reflector 24 and a mask 25 sleeved on the outer surface of the frame 21; the two sides of the bottom end of the frame 21 can be connected to the external scanning platform, the collection device 22 is fixed on the top surface of the frame 21, there are at least eight light sources 23 and they are respectively fixed on the four inner side surfaces of the frame 21 from bottom to top in sequence, the light sources 23 on the opposite sides of the frame 21 are symmetrically arranged, the light sources 23 between the adjacent sides of the frame 21 are staggered and distributed, and a reflector 24 is fixed at the lower end of the four inner sides of the frame 21; during the scanning process, the eight light sources can be turned on separately or simultaneously through the control system, and the eight light sources tilted around the frame cooperate with the corresponding reflectors to realize the scanning and collection of color images and high and low shadow image information in different directions of the image collection point of the scanned image, such that the scanning component only needs to scan once at a uniform speed to complete the collection of color images and high and low shadow image information of the image collection point, thereby improving the efficiency and accuracy of scanning and collecting information.

[0020] The light source 23 includes a lamp 231 and a light guide plate 232. The light guide plate 232 is fixedly arranged on the inner side of the frame 21 by a bracket, and the lamp 231 is arranged above the light guide plate 232 and its irradiation end is oriented in the same direction as the light guide plate 232. The light is more concentratedly reflected onto the image surface through the reflector, thereby improving the scanning and acquisition accuracy.

[0021] The acquisition device 22 and the light source 23 are both electrically connected to an external control system.

[0022] The working principle is as follows: the acquisition end of the acquisition device is moved and positioned to the image acquisition point. During the scanning process, all light sources are turned on at the same time through the control system. The light generated by all light sources is refracted to the top of the image acquisition point through the corresponding reflectors to form a light field with uniform light. At this time, the acquisition device will collect the color image of the image acquisition point; then the control system turns on one of the light sources in a clockwise direction from bottom to top and ensures that only one light source is turned on at the same time. The turned-on light sources all refract the light to the top of the image acquisition point through the reflectors opposite to them. The acquisition device thus collects 8 high and low shadow image information in four directions of front, back, left, right and left of the image acquisition point, thereby completing the collection of all information of the image acquisition point, without the need for multiple scans to obtain all the information of the image acquisition point.

[0023] The above-described implementation methods of the utility model do not constitute a limitation on the protection scope of the utility model. Any modification, equivalent replacement and improvement made within the spirit and principle of the utility model shall be included in the protection scope of the claims of the utility model.
