Geographical data collecting device
First Claim
1. A geographical data collecting device, comprising a distance measuring unit for projecting a distance measuring light and for measuring a distance to an object to be measured, an image pickup unit for taking an image in a measuring direction, a display unit for displaying an image picked up, a touch panel installed to match a position of screen of said display unit, a tilt sensor for detecting a tilting, an azimuth sensor for detecting a horizontal angle in the measuring direction, and a control arithmetic unit, wherein said image pickup unit takes an image of a measurement range, acquires a reference image, is directed to a selected measuring point in said reference image and acquires a measured image with the measuring point as a center,and wherein said control arithmetic unit calculates the measuring point in said reference image through an image matching of said reference image and said measured image and displays a measuring point on at least one of said reference image or said measured image.
