Abstract: The data set receiving unit 13 of the information processing apparatus 1 of an aspect example receives a data set that includes at least BIM data. The route setting processor 151 sets a route, which is arranged inside and/or outside a virtual building represented by the BIM data, based on the data set received. The virtual image set generating processor 152 generates a virtual image set of the virtual building along the route, based on the received data set and the set route. The inference model creating processor 153 creates an inference model by applying machine learning with training data that includes at least the generated virtual image set to a neural network. The inference model created is used to identify data of a building material from data acquired by measuring a building.

Abstract: An ophthalmic apparatus includes an acquiring unit, an OCT unit, an analyzer, and a calculator. The acquiring unit is configured to acquire a dioptric power in a first region including a fovea of a subject's eye. The OCT unit is configured to acquire OCT data of a fundus of the subject's eye using optical coherence tomography. The analyzer is configured to specify a shape of the fundus by analyzing the OCT data. The calculator is configured to calculate a dioptric power in a peripheral region of the first region of the fundus based on the dioptric power in the first region and the shape of the fundus.

Abstract: An ophthalmic system of an embodiment includes a slit lamp microscope and an information processing apparatus. The slit lamp microscope includes an image acquisition device that acquires a three dimensional image by photographing a subject's eye, and a first communication device that transmits the three dimensional image to the information processing apparatus. The information processing apparatus includes a second communication device that receives the three dimensional image transmitted by the first communication device, a display controller that displays a first image based on the three dimensional image on a display device, a partial region designation processor that designates a partial region of the first image, and a rendering processor that renders the three dimensional image based on the partial region to construct a second image. The display controller displays the second image on the display device.

Abstract: A slit lamp microscope of an aspect example includes an illumination system, first photographing system, fixation system, movement mechanism, and controller. The illumination system projects slit light onto an anterior segment of a subject's eye from a first direction. The first photographing system photographs the anterior segment onto which the slit light is being projected, from a second direction different from the first direction. The fixation system outputs fixation light for fixation of the subject's eye. The movement mechanism moves the illumination system and the first photographing system, the controller performs a first control for the movement mechanism to move at least the illumination system and a second control for the first photographing system to photograph the anterior segment a plurality of times in parallel with each other while causing the fixation system to output the fixation light.

Abstract: An ophthalmic observation apparatus according to an embodiment example includes a moving image generating unit, an analyzing processor, and a display controller. The moving image generating unit is configured to generate a moving image by photographing a subject's eye into which an artificial object has been inserted. The analyzing processor is configured to analyze a still image included in the moving image to identify a first site image corresponding to a predetermined site of the subject's eye and a second site image corresponding to a predetermined site of the artificial object. The display controller is configured to display, on a display device, the moving image, first position information that represents a position of the first site image, and second position information that represents a position of the second site image.
