Survey system and survey method using eyewear device

A survey method using:

• an eyewear device including a display, an eyewear-side communication unit, an acceleration sensor that detects forward, rearward, leftward, and rightward tilts of the device, an eyewear-side image pickup unit configured to capture an image in front of the eyewear device, a visual line sensor that detects a visual line of a measurement operator, and a control unit that displays the image captured by the eyewear-side image pickup unit on the display, displays a visual line marker on the display based on the visual line sensor, and transmits information on the tilt data detected by the acceleration sensor, the image captured by the eyewear-side image pickup unit, and a position of the visual line marker through the eyewear-side communication unit;
• and
• a surveying instrument including a communication unit, a distance-measuring unit that measures a distance to a target by emitting distance-measuring light, a drive unit that turns the distance-measuring unit in a horizontal direction and a vertical direction, an angle-measuring unit that measures a rotation angles in the horizontal direction and the vertical direction of the distance-measuring unit, an image pickup unit that captures an image in an emitting direction of the distance-measuring light, an image analyzing unit that identifies the image received from the communication unit in an image captured by the image pickup unit, and an arithmetic control unit that operates the drive unit according to the tilts received from the communication unit, identifies the position of the visual line marker in the image identified by the image analyzing unit, and recognizes the position of the visual line marker as a position of the target and measure the position of the target by the distance-measuring unit and the angle-measuring unit, wherein
• the eyewear device transmits the tilts of the eyewear device detected by the acceleration sensor to the surveying instrument,
• the surveying instrument operates the drive unit in response to the tilts,
• the eyewear device displays the image captured by the eyewear-side image pickup unit on the display, displays the visual line marker on the image, and transmits the image to the surveying instrument, and
• the surveying instrument captures an image of a position as a result of movement by the drive unit by the image pickup unit, identifies the image received from the eyewear device in the image captured by the image pickup unit, and recognizes a position of the visual line marker as a position of the target and measures the position of the target by the distance-measuring unit and the angle-measuring unit.
