Image technology for acquiring thumbnail for expressing structural meaning by identifying structural features manually or by computer

Abstract

The invention relates to an image technology for acquiring thumbnails for expressing structural meanings by identifying structural features manually or by a computer, in particular to a method for extracting thumbnails for abstractly or specifically expressing the structural meanings such as human life and working states by describing images, images and structural images of human behaviors, social behaviors, various tool equipment, life and working environments and the like. And a simplified graph structure with a certain public identification degree is achieved. According to the method, global or local brightness, color contrast and color gray value adjustment needs to be carried out on an obtained image, for a complex three-dimensional structure, secondary or multiple times of image sampling needs to be carried out under different working states or different backgrounds of equipment, then Boolean operation is carried out to obtain an intersection, and finally, the intersection is obtained. A contour having a common portion is derived from the plurality of images. According to the main principle of the method, drawings, images, concepts and the like of specific structures, events and the like in reality are abstracted and refined again, namely, the invented and created drawings are simplified and expressed again.

Description

Technical Field

[0001] Image recognition technology. Background Art

[0002] In people's daily life and work, they usually record their life and work by hand-drawing or taking pictures with cameras. Whether it is hand-drawing or camera, the pictures or images are in color, black and white, highlighting the subject, and expressing the environment, etc.

[0003] How to obtain the structure or meaning to be expressed in the picture or image, or how to process the picture to express the state of the picture abstractly or concretely. First, how to express the structure of the subject and abstractly summarize it into a simple graphic structure is the main purpose of the present invention.

[0004] Acquiring images of human body movements can describe and express the expressive meaning of human body movements; acquiring images of the structure of equipment and performing color analysis can obtain a thumbnail of the main structure, which is equivalent to further summarizing and abstracting the drawings to express the body structure. Summary of the invention

[0005] An image recognition processing technology that uses artificial or computer recognition of structural features to obtain thumbnails that express structural meanings. It is a method of extracting abstract or concrete thumbnails of structural meaning features that express human life and work status, etc. through images, videos and structural image descriptions of human behavior, social behavior, various tools and equipment, living and working environment, etc. in real life and work, so as to achieve an abstract simplified graphic structure with a certain degree of public recognition that is recognized by general engineering and technical personnel or the public.

[0006] When sampling images or graphics, the images or graphics to be expressed need to be pre-processed manually or by computer to remove the background pattern. The method is to add a white or solid-color background cloth behind the subject to be expressed, or to apply background light. In this way, after shooting, the scenery that is not related to the main structure can be removed.

[0007] After image sampling, the acquired image needs to be adjusted globally or locally in terms of brightness, color contrast, and color grayscale value. Some local structures also need to have their color grayscale gradient values ​​adjusted in order to obtain a graphic that highlights the main structural features.

[0008] By comparing image pixels, potential contours with large grayscale gradient changes are extracted and marked. After obtaining the highlighted main structural features, some structures still need to be processed manually or by computer, especially for images or graphic structures whose local features are not clear. It is also necessary to amplify and adjust the local color grayscale gradient values ​​in order to further obtain valuable local structural features.

[0009] For more complex three-dimensional structures, it is necessary to perform secondary or multiple image sampling under different working conditions of the equipment or under different backgrounds, and then perform Boolean operations to obtain the intersection and obtain the contours of common parts from multiple images.

[0010] The main structural features obtained have the characteristics of a structural thumbnail and can express structural features, rather than an abstract LOGO or an abstract symbol.

[0011] In human society, cars, trains, airplanes, and various equipment and tools used in human life all require drawings to express the design principles and their structures. It is difficult to express their specific structural forms using only the human society's words.

[0012] The main purpose of the present invention is to propose a technical method for simplifying the structural features of the "drawing" of the invention so as to more conveniently express the structural meaning of the drawing.

[0013] The main principle of the present invention is a technical method for re-abstracting and refining specific drawings, images, concepts, etc. of specific structures, events, etc. in reality. It is equivalent to a simplified drawing invented for the purpose of expressing inventions that has both the function of a drawing and the function of a pictographic meaning. In fact, it is a technical expression method of a "drawing" thumbnail containing specific structural features invented for the purpose of expressing inventions. It is equivalent to a technical method for summarizing and refining the abstract drawings and specification drawings in invention patents to form new thumbnails. BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 : Represents a thumbnail of a structure consisting of two similar circles, such as glasses, eyes, or car wheels. Figure 2 : represents a thumbnail of a structure similar to that of a bicycle, such as Figure 2 (a) a trolley, Figure 2 (b) a bicycle, Figure 2 (c) For riding a bicycle. Figure 3 : Thumbnails representing structural features similar to cars, such as Figure 3 (a) for automobiles, Figure 3 (b) for driving a motor vehicle. Figure 4 : A thumbnail representing an umbrella structure. Figure 5 : A thumbnail showing the structure of a transmission tower. DETAILED DESCRIPTION

[0014] Example 1 After extracting the image or image features of glasses, eyes or car wheels, two circles are obtained, and the two circles can be used to represent glasses, eyes or car wheels. Figure 1 .

[0015] Example 2 After extracting the structural image, video or image features of the bicycle, the side view or axonometric view is the most representative view of the bicycle in all views, such as up, down, left, right, front and back. The two wheels of the bicycle are abstractly extracted as two circles, and the handlebars are extracted as a "T" shape. The two circles O plus the bicycle handlebar T-shaped structure can represent the structural features of the bicycle. Figure 2 (a) A bicycle with Figure 2 (b) A trolley with Figure 2 (c) Cycling.

[0016] Example 3 After extracting the structural image, image or image features of the car, the side view or axonometric view is the most representative view of the car in the top, bottom, left, right, front and back views. After abstractly extracting the outline of the car image, it is two circles and a simple "L"-shaped structure similar to the cockpit. Using two circles O plus the L-shaped structure can simplify the representation of the structural features of the car. Figure 3 (a) For automobiles, Figure 3 (b) for driving a motor vehicle.

[0017] Example 4 Extended application: By referring to the methods of the above embodiments 1, 2 and 3, the shapes A and H used in human social communication can be introduced to form a new shape description thumbnail, with A on the top and Y on the bottom, which are combined to express the meaning of "umbrella". By simplifying or retouching the image, an abstract simplified graphic structure with a certain degree of public recognition that can be recognized by general engineering technicians or the public can be achieved, see the attached Figure 4 For umbrellas. Figure 5 With i on top and A on the bottom, they are combined to express the meaning of launching platform.
