Virtual Measurement System for Length Measurement Based on Visual-Inertial Odometry

This paper presents a brief structure of a multichannel virtual measurement system for length measurement based on Visual-Inertial Odometry. The system acquires measurement data from 3 axes MEMS gyroscope and accelerometer as well as a single camera and processing them to calculate a single length value. Some of the static characteristics of the system as well as known sources of uncertainties for every specific sensor channel are presented. The influence of the illminance and distance to the object measured as well as calibration model are investigated. This research can be useful for metrology analysis of VIO based measurement systems.
