Abstract
A survey machine capturing control part captures a captured image including a 2D mark on a survey object using a telescope. A survey machine recognizing control part detects a 2D mark image as a captured pattern, and recognizes a specific identification pattern by collating the detected captured pattern with an identification pattern of a 2D mark. A survey machine information displaying control part acquires and displays survey information on the captured image. A calculating control part calculates differences between a mark center position of 2D coordinates and a center position of 2D coordinates of a crosshair of the telescope. An adjusting control part adjusts a direction of the telescope so that the center position of the crosshair matches the mark center position. A ranging control part ranges the mark center position as measured values of coordinates. An information storing control part stores the measured values in the mark information table.
