Abstract
A technique enables a surveying device to acquire a direction of a target by using as little extra hardware as possible. A method aims a laser scanner, as a surveying device, at a reflective prism that is a target. The method includes obtaining a photographic image of the laser scanner that is captured by a smartphone from the reflective prism side and determining a direction of the reflective prism as seen from the laser scanner on the basis of the photographic image. The method also includes rotating the laser scanner to make the laser scanner face the reflective prism straight on, on the basis of the direction of the reflective prism as seen from the laser scanner.
Claims6
A target direction determining device configured to determine a direction of a target as seen from a surveying device, wherein the direction of the target as seen from the surveying device is determined on a basis of a photographic image of the surveying device that is captured from the target side.
A method for aiming a surveying device at a target, the method comprising:
- acquiring a photographic image of the surveying device that is captured from the target side;
- determining a direction of the target as seen from the surveying device on a basis of the photographic image;
- and
- rotating the surveying device to aim the surveying device at the target on a basis of the direction of the target as seen from the surveying device.
A method for aiming a surveying device at a target, the method comprising:
- acquiring a photographic image of the surveying device that is captured from the target side by a terminal equipped with a camera;
- transmitting the photographic image to a processing server by using a communication function of the terminal equipped with the camera;
- determining a direction of the target as seen from the surveying device on a basis of the photographic image, by the processing server;
- and
- rotating the surveying device to aim the surveying device at the target on a basis of the direction of the target.
