PROBLEM TO BE SOLVED: To simply find various values, to be surveyed, which are aimed in an ordinary surveying operation in a camera-type distance-measuring device which detects a distance up to a subject for every pixel. SOLUTION: A subject is irradiated with a distance-measuring light. Its reflected light is received by a CCD. A distance up to the subject corresponding to every pixel is detected, on the basis of a quantity of received light. A photographed image is displayed on an LCD37, which is installed on the back of a camera. A touch panel is arranged and installed at the LCD37, and a pixel which corresponds to a measuring point is selected by a pointing pen 60. On the basis of a distance which corresponds to the selected pixel, a coordinate value which uses the camera in the measuring point as a reference is found. When a value, to be measured, which is aimed is, e.g., an oblique distance between two measuring points, the two measuring points are selected by the pen 60, and the oblique distance between the two points is calculated on the basis of the found coordinate value. A calculated value to be surveyed is displayed on the LCD37. |
