We propose visionmeasurement scheme for estimating the distance or size of the object in static scene,which requires single camera\r\nwith 3-axis accelerometer sensor rotating around a fixed axis. First,we formulate the rotationmatrix and translation vector fromone\r\ncoordinate system of the camera to another in terms of the rotation angle, which can be figured out fromthe readouts of the sensor.\r\nSecond, with the camera calibration data and through coordinate system transformation, we propose a method for calculating the\r\norientation and position of the rotation axis relative to camera coordinate system. Finally, given the rotation angle and the images\r\nof the object in static scene at two different positions, one before and the other after camera rotation, the 3D coordinate of the point\r\non the object can be determined. Experimental results show the validity of our method.
