Abstract

The invention belongs to the technical field of network search, and particularly relates to a method and device for searching elementary mathematics handwritten formulas. A search website background is connected with a database containing all mathematical formulas in an elementary mathematics stage, and a user writes the content to be searched on a writing board, wherein the content is all names of a formula, a specific equation of the formula, one or more characters in the name of the formula, and any item in a section of formula in the equation of the formula, the writing content is captured by the writing board, the picture is transmitted to the computer, and then the picture is segmented by a digital image processing technology, finally, the segmented content is extracted and converted into character data, the data is subjected to fuzzy query in a database to find out all mathematical formulas corresponding to the character data, the content needing to be searched can be found more clearly through fuzzy query, and the tablet personal computer is used as the writing board to write the content needing to be searched more conveniently compared with a traditional keyboard for typewriting.

Description

technical field [0001] The invention belongs to the technical field of network search, and particularly proposes a search method and device for elementary mathematics handwritten formulas. Background technique [0002] Elementary mathematics, referred to as elementary mathematics, refers to the mathematics content usually taught in elementary or middle school. Compared with advanced mathematics, elementary mathematics in elementary school includes: integers, fractions, and four arithmetic operations in elementary school, number and algebra, space and graphics, Simple statistics and possibility, linear equations in one yuan, circles, positive and negative numbers, elementary three-dimensional geometry, elementary mathematics are included in the junior high school stage, and the algebra part includes: rational numbers (positive and negative numbers and their operations), real numbers (radical operations), Plane Cartesian coordinate system, basic functions (linear function, qua...
