    • PROBLEM TO BE SOLVED: To provide a system and a method which are excellent in reliability and can exactly detect a position of a mobile object while suppressing influences of errors to the minimum, even if the errors exist in measured angles.
      SOLUTION: Angles between respective direction lines which connect three optical beacons to the mobile object 2, are measured, and two or more combinations each of which includes two angles among measured angles as measurement angles, are selected. Then, positions of the mobile object 2 are computed in selected combinations respectively by using the measurement angles and known positions of each optical beacon. Furthermore, percentage changes in above computed positions corresponding to changes in measurement angles are estimated in the selected combinations respectively. When carrying out above computation, the position of the mobile object is computed by using the combination of measurement angles which is selected from above-mentioned selected combinations such that the estimated percentage change is minimum.

    • PROBLEM TO BE SOLVED: To simply and accurately acquire the attitude of an attitude sensor mounted on an imaging device with respect to the imaging device.
      SOLUTION: A sensor calibration device for calibrating the attitude sensor mounted on an imaging device, calculates the relative attitude of the attitude sensor to the imaging device by using information on the image coordinates of an index detected from a photographed image and an attitude measured value. In that case, parameters are found for minimizing an error between an actual measured value of the image coordinates of the index and a theoretical value of image coordinates of the index calculated from estimated value of parameters with the relative attitude of the attitude sensor to the imaging device and the position of the imaging device taken as unknown parameters.

    • PROBLEM TO BE SOLVED: To realize a position detecting system for the inside of an examinee's body, capable of detecting the position of a device inserted into the examinee's body and its pointing direction, regardless of the presence of organs. SOLUTION: In an endoscope of a capsule shape 2, a magnetic field generation member 24 floats in a fluid 27 sealed in a case 26, and is so positioned that its image can be projected to a CCD (charge coupled device) 13 through an optical system 32 and a reflecting member 33. The longitudinal side of the permanent magnetic 29 of the magnetic field generation 24 is always kept to point vertically by providing a weight member 30. When the CCD 13 whose view is fixed to the endoscope of the capsule shape 2 captures an image of the magnetic field generation member 24, and the direction between the pointing direction of the endoscope of the capsule shape 2 and the vertical direction is detected.
