摘要： A surveying system (100) includes a target unit (10) including a reflection target (11) and an encoder pattern (13B) showing an angle of the target unit (10), a scanner device (30) configured to acquire three-dimensional point cloud data, acquire measured coordinates of the reflection target (11) by target scanning, and acquire an encoder pattern read angle by optically reading the encoder pattern (13B), and a leveling base (70) configured to selectively allow either of the target unit (10) and the scanner device (30) to be removably mounted so as to share a central axis in the vertical direction, and having offset angles, being known, with respect to each of the target unit (10) and the scanner device (30), and calculates a direction angle of the leveling base (70) based on the encoder pattern read angle of the target unit (10) mounted on the leveling base (70) and the offset angle of the target unit (10), acquired by the scanner device (30), calculates coordinates of an installation point of the target unit (10) based on the measured coordinates of the reflection target (11) and the direction angle, and calculates a direction angle of the scanner device (30) based on the offset angle of the scanner device (30) and the direction angle of the leveling base on which the scanner device (30) is mounted.

摘要： Generation of an inappropriate image portion in an orthographic image due to occlusion is prevented. An image processing device includes an image data receiving part that receives image data of multiple photographed images taken by photographing an object from different positions, a coordinate designating part that receives designation of a specific position in the object, and an optimum-condition satisfying image selecting part that selects a photographed image that is taken from a direction in a specific range relative to the specific position, from among the multiple photographed images. The selected photographed image is used to obtain pixel information of the specific position.
