摘要： A marking apparatus includes a marking apparatus main body including a target, a traveling mechanism for automatically traveling on a traveling surface, and a printer, and a control unit configured to control the printer and the mechanism. The control unit controls the traveling so that the mechanism automatically travels along a set traveling route, the control unit compares position coordinates of the marking apparatus main body obtained from three-dimensional position coordinates of the target during traveling input at predetermined intervals with the traveling route, and corrects traveling to eliminate a deviation from the traveling route, the control unit controls the printer so as to print the marking information set at a position corresponding to the position coordinates of the marking apparatus main body, and traveling route data setting the traveling route and marking information data defining the marking information are created based on CAD design data.

摘要： Information of an instrument point of a surveying apparatus is more simply and easily acquired. Positioning data that is obtained by a first surveying apparatus in which exterior orientation parameters are known, and positioning data that is obtained by a second surveying apparatus in which exterior orientation parameters are unknown, are received. The first surveying apparatus and the second surveying apparatus are configured to obtain positioning data by measuring multiple positions of a UAV that is flying. A piece of positioning data is acquired from the positioning data of the UAV obtained by the first surveying apparatus and from the positioning data of the UAV obtained by the second surveying apparatus. These pieces of positioning data are in a correspondence relationship. The position of the second surveying apparatus is calculated based on the pieces of positioning data that are in the correspondence relationship, by a method of resection.

摘要： An ophthalmologic information processing apparatus includes an analyzer, a storage unit, a region editing unit, and a display controller. The analyzer is configured to analyze data of a subject's eye optically acquired by projecting light onto the subject's eye, and to specify a lesion region in the subject's eye. The storage unit stores image data of the subject's eye. The region editing unit is configured to specify a changed region by changing the lesion region based on operation information corresponding to an operation content on an operating unit. The display controller is configured to cause an image of the subject's eye to be displayed on a display means based on the image data stored in the storage unit, and to cause a region corresponding to the changed region in the image of the subject's eye to be displayed so as to be identifiable.

摘要： A tilt analysis method analyzing a tilt of a columnar object is disclosed. The tilt analysis method includes: acquiring a reference value on the basis of a first position of a reflector of a measurement target device attached to a column foot portion of the columnar object; acquiring, in response to an execution instruction, a column top value on the basis of a second position of the reflector of the measurement target device attached to a column top of the columnar object, the execution instruction being received by an input section and inputted via a column top value acquisition instruction section displayed on a display section of a terminal device; generating tilt information indicating in which direction the columnar object tilts based on the reference value and the column top value; and causing the display section to display the tilt information including graphic display.
