Description
Technical Field
The invention relates to the technical field of digital stationery, in particular to an original handwriting recording intelligent pen based on inertial measurement.
Background
The inertial measurement system is a combined system for measuring the acceleration of the vehicle relative to the ground motion in real time by using inertial sensing elements such as gyroscopes and accelerometers and an electronic computer to determine the position of the vehicle and the earth gravitational field parameters. The system is developed on the basis of an inertial navigation system and is divided into a local horizontal inertial system and a space stabilizing system. The first category of local horizontal north-seeking inertial systems is commonly used. Handwriting refers to the special physical characteristics of each individual written word, namely handwriting. Different people will necessarily form different writings, which can reflect the characteristics of different writers. Physical, psychological factors and even physical appearance can have an effect on handwriting. Handwriting authentication and pen learning, etc. are all questions about handwriting. Furthermore, handwriting features belong to behavioral biometrics. For each writer, the handwriting has relative stability as a whole, and the local variation of the handwriting is the inherent characteristic of the handwriting of each writer. The handwriting of different writers is greatly different. Handwriting recognition is an important branch of biometric recognition. Handwriting recognition has wide application in social life. Such as the signing of important agreements between countries, the signature comparison of banks and financial departments, the criminal investigation and forensic evidence of public security and judicial departments, and the like.
