Resumen
Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq) Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES) This work proposes a low cost calibration method for micro-electro-mechanical inertial (MEMS) gyroscopes, using a camera pan-tilt base. The use of MEMS gyroscopes in practical robotics measurements requires preliminary calibration. Three calibration procedures are currently found in the literature to estimate the sensor calibration parameters which are based on static, quasi-static and dynamic measurements. This paper focus in the investigation of quasistatic calibration procedure which consists in moving the sensor in a path with known kinematics. High complexity calibration mechanisms were proposed in the literature, which require user intervention. This paper proposes a simple procedure to calibrate a gyroscope using an automatic camera pan tilt base. The sensor parameters are estimated using direct pseudo inversion of a coefficients matrix. The method is validated experimentally on two different IMU platforms. 121 125 CNPq CAPES FAPEAM Foundations Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq) Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES) 19th IEEE International Conference on Intelligent Transportation Systems (ITSC) NOV 01-04, 2016 Rio de Janeiro, BRAZIL
