A method of searching using auxiliary means such as guide images may be considered, but this method has the problem of being too time-consuming.

This invention was made to solve the above problems, and by using the shape of the object itself as a search keyword, even a person without basic knowledge of the name of the object can search for the desired object. An object of the present invention is to obtain a data retrieval device capable of quickly and reliably retrieving data required by a user.

[Means for solving problems]

The data retrieval device according to the invention inputs the shape of the search object into the image input device as image data, digitizes this image and stores it in the original shape storage unit, and also stores many types of information in advance in the information function. The shape information of the search target object is digitized and stored, this shape information is extracted from the information file and stored in the search key - shape memory section, and the image information of the original shape memory section is used as a keyword to search for this shape information. A shape comparison section compares the image information and the shape information, and if the comparison result shows that the image information and shape information are extremely similar, the search information extraction section extracts data regarding the shape from the information file, This data is configured to be displayed on a data display section.

[For production]

In the data comparison section of the data search device in this invention,
The image information of the shape of the object itself is compared one after another with the shape information selected from a large number of preset shape information of the search target, and only when these pieces of information are extremely similar, the data related to the shape information is It works by extracting information from the file and displaying it. Therefore, there is no need to search based on the name of the object or model name, and the operator does not need to be skilled.

〔Example〕 .

An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, 14 is an image input device that inputs a three-dimensional image of the object shown in FIG. 2, 21 is a graphic information processing circuit that digitizes the shape of the target, and 22 is an original shape memory that stores this shape. Section 23 is an information file storing the shapes of a large number of objects in digital format, and corresponds to the main memory 12 in FIG. Reference numeral 24 denotes an information file image reading unit for extracting shape information from the information file 2.3; 25 denotes a search key shape memory unit for storing this shape as image information; 2;
Reference numeral 6 denotes a shape comparison unit that uses the image information in the original shape storage unit 22 as a keyword and compares this image information with the shape information in the search key shape storage unit 25, and 27 indicates a case in which the image information is extremely similar as a result of the comparison. Further, a search information retrieval section 16 retrieves the data of the object from the information file 23, and a data display section 16 serves as the display device for displaying the retrieved data.In this embodiment, the CRT t-t' is not used.
