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 said taken image,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, anda control arithmetic unit, wherein said control arithmetic unit;
takes an image of a measurement range using said image pickup unit,displays said taken image of said measurement range as a reference image on said display unit,acquires a measured image with a measuring point as a center using said image pickup unit,determines a distance from said geographical data collecting device to said acquired measuring point using said distance measuring unit,uses image matching to calculate the location of the measuring point in said reference image,repeats said acquires, determines and uses steps for at least one additional measuring point, anddisplays previously measured measuring points on said reference image.

Abstract
The present invention provides a geographical data collecting device, which comprises a distance measuring unit 5 for projecting a distance measuring light and for measuring a distance to an object to be measured, an image pickup unit 3 for taking an image in a measuring direction, a display unit 6 for displaying an image picked up, a touch panel installed to match a position of screen of the display unit, a tilt sensor 11 for detecting a tilting, an azimuth sensor 12 for detecting a horizontal angle in the measuring direction, and a control arithmetic unit 8, wherein the image pickup unit takes an image of a measurement range, acquires a reference image, is directed to a selected measuring point in the 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 the reference image through an image matching of the reference image and the measured image and displays a measuring point on at least one of the reference image or the measured image.

11. A method of collecting geographical data, using a geographical data collecting device comprising an image pickup unit, a display unit, a distance measuring unit and an arithmetic unit, said method comprising:
-
taking an image of a measurement range using said image pickup unit; displaying said image on said display unit as a reference image; selecting a measuring point in said reference image; acquiring a measured image with the measuring point as a center using said image pickup unit; determining a distance from said geographical data collecting device to said measuring point using said distance measuring unit; using image matching to calculate the location of said measuring point in said reference image using said control arithmetic unit; displaying the measuring point on said reference image; and
repeating said selecting, acquiring, determining, using, anddisplaying steps for at least one additional measuring point, wherein each measuring point remains displayed on said reference image.
