A Low-Cost Calibration Method for Low-Cost MEMS Accelerometers Based on 3D Printing.

摘要: A ubiquitous sensor in embedded systems is the accelerometer, as it enables a range of applications. However, accelerometers experience nonlinearities their outputs caused by error terms and axes misalignment. These errors are major concern because, applications such navigations systems, they accumulate over time, degrading position accuracy. Through calibration procedure, can be modeled compensated. Many methods have been proposed; however, require sophisticated equipment available only laboratories, which makes them complex expensive. In this article, simple, practical, low-cost method proposed. It uses 3D printed polyhedron, benefiting from popularisation printing present day. Additionally, each polyhedron could hold much 14 sensors, calibrated simultaneously. The was performed with significantly reduced root-mean-square (RMSE) output. RMSE compared reported similar proposals, our resulted higher performance. proposal accelerometer at low-cost, anywhere anytime, not experts laboratories. Compensating sensor's inherent thus increases accuracy its
