Distance Estimation Using Inertial Sensor and Vision

다국어 초록 (Multilingual Abstract)

A simple distance estimation algorithm using inertial sensors and a mono camera is proposed. Two images of a target are obtained by moving a mono camera. The movement of the camera is estimated using inertial sensors and used as the baseline for the distance estimation. Through experiments, the accuracy of the proposed method is evaluated, where the distance error is 3.9% on average in a few meter ranges.
