Abstract

A light from a light source is irradiated to a target position, and the position of the irradiated light is displayed on a screen. A driver moves a vehicle-type measurement system so that the light is kept irradiated to the target position. While the vehicle-type measurement system is moving, a GPS receiver outputs GPS measurement data indicating the position of the vehicle-type measurement system based on a signal from a GPS antenna, and the data is stored in a storage medium. Thus, by moving the vehicle-type measurement system so that the light is kept irradiated to the target position, the GPS measurement data which indicates a position of a predetermined distance from the target position can be continuously measured.

Claims

1. A vehicle-type measurement system comprising:

a light source which irradiates a light to a target position while traveling;

a screen which displays a position of the irradiated light to the target position;

a GPS antenna;

a GPS receiver which is connected to the GPS antenna and outputs GPS measurement data; and

a data storing unit which stores the GPS measurement data output from the GPS receiver in a storage medium.

2. The vehicle-type measurement system according to claim 1, further comprising a correction data receiver which receives correction data of the GPS measurement data, wherein the GPS receiver corrects the GPS measurement data by utilizing the correction data.

3. The vehicle-type measurement system according to claim 1, further comprising:

a display device which displays map data in a neighborhood of a current position of the vehicle-type measurement system; and

a measurement position display unit which displays a measurement position, based on the GPS measurement data, on the display device.

4. The vehicle-type measurement system according to claim 1, wherein the data storing unit stores the GPS measurement data in the storage medium in a manner associated with place name.

5. The vehicle-type measurement system according to claim 1, further comprising an image-capturing device which captures a neighboring image, wherein the data storing unit stores image data captured by the image-capturing device in the storage medium in a manner associated with the GPS measurement data.

6. A vehicle-type measurement system comprising:

a light source which irradiates a light to a top of a target object while traveling;

a screen which displays a position of the irradiated light to the top of the target object;

an angle detection unit which detects an emission angle of the light; and

a calculation unit which calculates height of the target object based on the emission angle, a distance between the vehicle-type measurement system and the target object, and height of the vehicle-type measurement system.

7. The vehicle-type measurement system according to claim 6, further comprising:

a GPS antenna;

a GPS receiver which is connected to the GPS antenna and outputs GPS measurement data; and

a data storing unit which stores GPS measurement data output from the GPS receiver in a storage medium, together with the calculated height of the target object.
