  • Patent number: 10469754
    Abstract: A position guiding device includes a mobile terminal having an imaging part and display, a position information acquiring part for acquiring current coordinate information and target coordinate information, a direction sensor for acquiring direction information, and a controller to generate a target image. The mobile terminal is attached to a pole so as to position a pole tip within an angle of view. The controller acquires, from the position information acquiring part, current coordinate information representing a position at where the pole tip points, defines a horizontal surface including the pole tip as a measurement surface, generates corrected coordinate information by shifting the target coordinate information to a position on the measurement surface, generates the target image in which a target position marker is put at a position representing the corrected coordinate information in the image obtained by the imaging part.
