Embodiment Construction

[0019] Hereinafter, the best mode for carrying out the present invention will be described with reference to the drawings.

[0020] figure 1 In the following, the geographical data collection device 1 of the present invention will be described.

[0021] Among the figure, 2 is a portable casing, on which an imaging unit 3, a GPS device 4, a display unit 5 and an operating unit 6 are arranged, and in addition, a control calculation unit 7, a storage 8, input and output control unit (I / O) 9, gyro sensor 11, orientation sensor 12 and wireless receiving unit 13, the camera unit 3 is provided with an objective lens 14, CCD, CMOS sensor, etc. are composed of a collection of many pixels The imaging element 15 can determine the position of each pixel (the position in the imaging element), and the image of the object imaged on the imaging element 15 is output from the imaging element 15 to the control unit as a digital image signal. The calculation unit 7 stores the image in the stora...

Abstract

A geographic data collecting system, comprising an image pickup unit for taking a digital image including a measuring point of an object to be measured, a GPS unit, an azimuth sensor for detecting an image pickup direction, a display unit for displaying the image taken, a receiving unit for receiving correction information to correct measurement result of the GPS unit, and a control arithmetic unit for obtaining corrected position data by correcting the measurement result based on the correction information and for associating the image acquired by the image pickup unit with the corrected position data and for storing the image and the corrected position data in a storage unit.

Description

technical field [0001] The present invention relates to a geographic data collection device using GPS (Global Positioning System), and more particularly to a geographic data collection device that collects image data associated with coordinate data as geographic data. Background technique [0002] In recent years, navigation systems using electronic maps have become popular, and the navigation systems are installed in vehicles, or installed and used as additional functions of mobile phones. [0003] With the popularization of navigation systems, geographic data on electronic maps is required to diversify. In order to obtain more detailed geographic data or to facilitate visual judgment, symbols and stereoscopic images added to maps are required. [0004] For example, for the collection of geographical data transferred to the electronic map, the staff visit the site in person to obtain the characteristic geographical information of the site, such as the location of public bui...
