  • Publication number: 20240020865
    Abstract: A calibration method for a distance measurement device that is mounted inside a moving body, images outside of the moving body without intervention of a transparent body, and calculates a distance to an object by using disparity between images captured from at least two points of view, the method including: a first process of capturing a first-image-for-calibration and a second-image-for-calibration at different distances between a first-object-for-calibration and the distance measurement device without intervention of the transparent body and calculating correction information for converting disparity information calculated from image information of each of the first-image-for-calibration and the second-image-for-calibration into distance information; and a second process of capturing a third-image-for-calibration from a second-object-for-calibration that is located at least at one distance via the transparent body and modifying the correction information calculated in the first process on the basis of image

  • Patent number: 8710455
    Abstract: A charged-particle beam lens includes a plate-like anode, a plate-like cathode, and an insulator disposed between the anode and the cathode. The insulator, the anode, and the cathode have a passage portion through which a charged beam is passed. A high-resistance film is formed on an inner side of the insulator, the inner side forming the passage portion, or an outermost side of insulator, and the anode and the cathode are electrically connected together via the high-resistance film. The anode and the high-resistance film, and the cathode and the high-resistance film each contain the same metal or semiconductor element and have different resistant values. This suppresses electric field concentration due to an increase in resistance and poor connection at the interface between the anode and the cathode and the high-resistance film or at the interface between the electroconductive film and the high-resistance film, thus suppressing generation of discharge.
