Investigations to digitizingof the gyro oscillation swing by a line camera

Abstract

The purpose of this work is to develop a technology for an automatic measurement process for determining the azimuth by the "Gyromax AK-2M" gyroscope. The accuracy of determining the principal values should be higher than by manual procedure. A method for digitizing the gyro oscillations using a camera with a linear sensor and programming code is proposed in this work. The working possibility of the line camera from Coptonix™ company was investigated, as well as the possibility of its connection to a single board computer Raspberry Pi 3B for data transmission and processing. The possibility of using the Python 3.0 programming language for these tasks was tested. Methodology. To implement this project, an integrated approach was used, using devices such as a camera with a linear sensor, a single board computer and facility, that simulates gyroscope oscillations. This research includes investigations in digitizing of data, computing the azimuth values and automatizing these processes. For automatized data computation were used the same two methods as in the regular manual measurements-Turning point method (TPM) and Pass-Through method (PTM). Results. The result of this work is an automated oscillation measurement system, that can be applied in gyroscopes. The system includes developed software, which connects the user to the linear camera and processing computer, records the necessary data, transfers them to the client-computer and calculates the necessary values. For the convenience of using the program by other users, the program is provided with a graphical user interface. The result of the program is a file with the extension XML, which contains data about measurements. Scientific novelty and practical significance. The new method of digitizing the gyroscope oscillations is proposed in this work. Application of a line camera and a single board computer for the digitization of measurements opens a lot of possibilities for improving the automation processes of the geodetic devices, which could increase the accuracy of measurement and decrease its duration. By developing this method of digitization, it is possible to start production of an improved version of gyro add-on GYROMAX AK-2M.

“…In the previous work of the author [Heger, et al, 2019] there was an attempt to use a linear camera as a motion sensor, which converted the intensity of light into a voltage signal but was connected to a single-board computer, which allowed to transmit data wirelessly. However, the size and format of the linear sensor did not allow the implementation of this idea in the working system.…”
