Abstract

The invention discloses a device capable of recognizing a handwritten mathematical formula. The device comprises a box body, wherein the top of the box body is fixedly connected to an operation box; the top of the operation box is fixedly connected to a supporting plate through a connecting column; the bottom of the supporting plate is fixedly connected to a camera; a rotating shaft penetrates through the two sides of the bottom of the operation box; the outer surface of the rotating shaft is rotationally connected to belt pulleys; and the two belt pulleys are provided. The invention relates to the technical field of mathematics. According to the device capable of recognizing the handwritten mathematical formula, the belt pulleys and a belt are matched to drive the paper on which a mathematical problem needs to be solved to transmit, test questions below a light transmitting mirror are shot in sequence and are transmitted into a data processor, and the device solves the problems that some mathematical formulas are written by handwriting, but the handwritten formulas are not recognized by some people, a user needs to research, so that a lot of time can be wasted, and the working efficiency can be reduced.

Description

technical field [0001] The invention relates to the technical field of mathematics, in particular to a device capable of recognizing handwritten mathematical formulas. Background technique [0002] Mathematics originated from the early production activities of human beings. From the perspective of mathematics itself, their mathematical knowledge is only obtained from observation and experience, without comprehensive conclusions and proofs. However, their contributions to mathematics must be fully affirmed. Knowledge of basic mathematics and Application is an integral part of individual and corporate life, and since then its development has continued in small increments, but algebra and geometry at that time remained independent for a long time, algebra can be said It is the most widely accepted "mathematics". It can be said that the first mathematics that everyone comes into contact with from childhood is algebra. As a subject of "number", algebra is also the most important ...
