    Abstract: Provided is a point cloud analysis device that curbs a decrease in model estimation accuracy due to a laser measurement point cloud. A clustering unit (30) clusters a point cloud representing a three-dimensional point on an object obtained by a measurement unit mounted on a moving body and performing measurement while scanning a measurement position, within a scan line, to obtain a point cloud cluster. A central axis direction estimation unit (32) estimates a central axis direction based on the point cloud cluster. A direction-dependent local effective length estimation unit (34) estimates a local effective length based on an estimated central axis direction and an interval of scan lines, the local effective length being a length when a length of projection of the point cloud cluster in a central axis direction for each of the point cloud clusters is interpolated by an amount of a loss part of the point cloud.

    Abstract: A slit lamp microscope according to some aspect examples includes an illumination system and photographing system. The illumination system projects slit light onto an anterior segment of a subject's eye. The photographing system includes an optical system and an image sensor. The optical system directs light from the anterior segment onto which the slit light is being projected. The image sensor includes a light detecting surface that receives the light directed by the optical system. Further, a subject plane, a principal plane of the optical system, and the light detecting surface are arranged so as to satisfy a Scheimpflug condition. Here, the subject plane includes a focal point of the illumination system in which a position of the focal point is shifted on account of a refractive index of a tissue of the anterior segment.
