3D measurement of a moving object using a moving camera attached with a 6-axis sensor

Measurement using a moving camera and a 6-axis sensor under the camera is proposed to determine the distance from the camera to the surface of a moving object and the object's position movement in two continuous frame images. This makes it possible to measure the 3D position of a moving object at half of the computational cost while keeping the same accuracy as using a stereo camera. 3D measurement experiments with several original images show that the computational time using the proposal is about twice as fast as that of a stereo camera. The proposed method is planning to be used to vehicles or mobile robots avoid obstacles, and its use as a depth meter is also investigated.
