Calibration method of a spherical sensor

Abstract

The invention relates to a calibration method of a ball internal sensor, wherein the calibration method comprises the steps: 1) connecting a to-be-calibrated sensor, and receiving data sent by the sensor; 2) collecting data of points on a plurality of different faces of a ball body, to obtain a ball center, and calculating a ball center value; and if the ball center value conforms to a preset validation value range, judging that the current ball center value is a correct validation value; and 3) circulating the step 1) and the step 2), collecting a plurality of correct validation values, and completing sensor calibration. After connection is successful, data are collected, whether the collected data are valid is judged, if the collected data are valid, the data writing is performed after the validation value is obtained; when the validation value conforms to a preset inspection rule, the sensor calibration is completed. The connection is conformed through a visual interface, and different states are displayed to judging whether the connection is valid. Whether the ball is stationary is automatically judged during data collection, and only the data sent in the stationary state are guaranteed to be collected during the inspection process, so as to achieve the accuracy of data collection.

Description

technical field [0001] The invention relates to a sensor calibration method, more specifically, to a calibration method of an in-sphere sensor. Background technique [0002] When multiple smart balls of the same product are connected, receive data and process them, if you do not filter and only confirm that one of the smart balls is connected and receives data, data from multiple different smart balls will be received at the same time , resulting in data errors. [0003] Moreover, for smart balls with built-in sensors, such as accelerometers, gyroscopes, magnetometers and other sensors, if the data transmission is not checked and offset, the results obtained by processing the received data will also have obvious errors, even up to Less than the desired effect. [0004] However, there is a lack of technical solutions such as connection determination and data verification for the smart ball sending data in the prior art, which makes it impossible to achieve more accurate app...
