A quaternion based sensor fusion algorithm that fuses accelerometers and gyroscopes and optionally magnetometers. Python library for communication between raspberry pi and MPU imu. Repository holding code corresponding the information on the new "Arduino Nano 33 BLE" board as it's project page. This packages wraps the implementation of Madgwick algorithm to get orientation of an object based on accelerometer and gyroscope readings for Golang. This component uses Madgwick algorithm to obtain roll, pitch, yaw of IMU. This repository contains most of the files used by me, Mairon S. Wolniewicz, to develop the final project of my Aerospace Engineer undergraduation studies at Federal University of Santa Catarina.

Studies on the movement analysis of human, animals and objects have been continuing for centuries. These analyzes are carried out to the extent permitted by the technology in their time. Developments in current technology and computing have enabled more quantitative and objective analyzes. This includes placing the markers on the object and measuring the light-based motion. Moreover, it is possible to measure this movement in 3D with the help of cameras. However, the area where the measurement can be made is limited by the area surrounding by the cameras. The development of micromachining technology and microelectromechanical systems has enabled the inertial sensors such as accelerometers and gyroscopes to be mounted to the body and small enough to be mounted on inertial measurement units and motion tracking devices. By combining gyroscope, accelerometer and magnetometer depending on usage data, it is possible to analyze movements in any position in space without being dependent to the cameras. Inertial detection technology has great advantage to measure the movement outside the laboratory, also to obtain unlimited or wide measurement data. Being wearable in contrast to the camera system provides great flexibility. In addition, the costs have decreased considerably since there is no need for a special laboratory or any other requirements. Thanks to their low cost, compact structure and usage flexibility, inertial measurement units have reached wide range of usage. In addition to military field, they are also being used in industry, rehabilitation, sports sciences, virtual reality, game industry, animation and motion capture, mobile phones, smart watches and many other fields.

In this work, four sensor fusion algorithms for inertial measurement unit data to determine the orientation of a device are assessed regarding their usability in a hardware restricted environment such as body-worn sensor nodes. The assessment is done for both the functional and the extra-functional properties in the context of human operated devices. The four algorithms are implemented in three data formats: bit floating-point, bit fixed-point and bit fixed-point and compared regarding code size, computational effort, and fusion quality. For the assessment of the functional properties, the sensor fusion output is compared to a camera generated reference and analyzed in an extensive statistical analysis to determine how data format, algorithm, and human interaction influence the quality of the sensor fusion.

A not-for-profit organization, IEEE is the world's largest technical professional organization dedicated to advancing technology for the benefit of humanity. Use of this web site signifies your agreement to the terms and conditions. Magnetic field fluctuations and inefficient sensor fusion still inhibit deployment. In this article, we introduce a new algorithm, an extended complementary filter ECF , to derive 3-D rigid body orientation from inertial sensing suites addressing these challenges. The ECF combines computational efficiency of classic complementary filters with improved accuracy compared to popular optimization filters. We present a complete formulation of the algorithm, including an extension to address the challenge of orientation accuracy in the presence of fluctuating magnetic fields. Performance is tested under a variety of conditions and benchmarked against the commonly used gradient decent inertial sensor fusion algorithm.
