Abstract

The present invention provides a geographical data collecting device, including 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 in a measuring direction, an azimuth sensor 12 for detecting a horizontal angle in the measuring direction, and a control arithmetic unit 8, wherein the control arithmetic unit displays a scale to indicate horizontal and vertical lines on the display unit and controls the scale display so that the scale always indicates the horizontal and the vertical lines in the image based on a result of detection of tilting from the tilt sensor.

Claims

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 in the measuring direction, an azimuth sensor for detecting a horizontal angle in the measuring direction, and a control arithmetic unit, wherein said control arithmetic unit displays a scale to indicate horizontal and vertical lines on the display unit and controls the scale display so that said scale always indicates the horizontal and the vertical lines in the image based on a result of detection of tilting from said tilt sensor.

2. A geographical data collecting device according to claim 1, wherein said control arithmetic unit measures a distance between two points based on an image including an object to be measured, based on a result of a distance measurement to the object to be measured as acquired at said distance measuring unit, based on two points designated along said scale, and based on a field angle between said two points.

3. A geographical data collecting device according to claim 2, wherein said two points are designated along said scale to indicate a vertical line and a vertical distance between said two points is measured.

4. A geographical data collecting device according to claim 2, wherein said two points are designated along said scale to indicate a horizontal line and a horizontal distance between said two points is measured.

5. A geographical data collecting device according to claim 1, wherein a scale value is also displayed on said scale, and said scale value is changed to match the measured distance.

6. A geographical data collecting device according to claim 1, further comprising a GPS device, wherein said control arithmetic unit calculates a three-dimensional coordinates of the measuring point based on a geographical data obtained by said GPS device, on an azimuth angle of the measuring point measured by said azimuth sensor, and on a result of a distance measurement.

7. A geographical data collecting device according to claim 6, further comprising a radio receiving unit, a compensation information 21 is received by said radio receiving unit, and a measurement result measured by said GPS device is compensated based on said compensation information.
