Abstract

PURPOSE:To reduce the survey error and drastically reduce the fatigue of eyes in the surveying work for a long time. CONSTITUTION:A telescope 3 arranged on the front surface of an equipment body 2, videocamera 4 installed on the eyepiece part of the telescope 3, display screen 6 connected to the videocamera 4, and a collimator 8 for the rough collimation for a target point 7 are provided. The setting in the direction of the equipment body 2 is carried out by carrying out the rough collimation for the target point 7 with the collimator 8, and then an image obtained by viewing it through the telescope 3 is photographed, and the image is projected on the display screen 6, and fine adjustment is carried out so that the cross point of the cross lines 10 on the display screen 6 reaches the target point.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a surveying method capable of surveying on a display screen in a surveying instrument such as a light-wave rangefinder, a transit, and a level.

[0002]

2. Description of the Related Art Conventionally, in a surveying instrument such as a light-wave rangefinder, a transit, and a level, a telescope is used to measure a target object, and fine adjustment is made so that the intersection of the crosshairs inside the target object comes to the target object. I am doing distance measurement and angle measurement.

[0003]

However, the above-mentioned conventional surveying method is a work with one eye of a person, and since there are many factors that cause individual differences in the survey results, the surveying work is not always accurate, and individual surveying is not always possible. It requires some skill to carry out accurate surveys, including errors due to differences. In addition, in long-time surveying work, the eyestrain often leads to a situation in which accurate surveying cannot be performed, which requires a rest period, which lowers the efficiency of surveying.

The present invention solves the above problems, and can reduce the surveying error and the eye fatigue during the surveying work for a long period of time, thus greatly improving the efficiency of the surveying work. It is an object to provide a surveying method using a display screen that can be improved.

[0005]

To this end, a surveying method using a display screen according to the present invention includes a telescope 3 arranged on the front surface of an apparatus body 2 and a video camera detachably attached to an eyepiece portion of the telescope 3. 4, a display screen 6 connected to the video camera 4, and a sighting device 8 for roughly aiming the target point 7. The aiming device 8 roughly aims at the target point 7, Set the direction of 2 and then take an image obtained by looking into the telescope 3,
The image is displayed on the display screen 6, and the intersection of the crosshairs 10 on the display screen 6
The feature is that fine adjustment is performed so as to reach the target point. It should be noted that the numbers added to the above-mentioned configurations are for comparison with the drawings in order to facilitate the understanding of the present invention, and the configurations of the present invention are not limited thereby.

[0006]

In the present invention, the image obtained by looking through the telescope is photographed, the image is displayed on the display screen, and the crosshair 1 on the display screen is observed while watching the screen.
Fine adjustment is performed so that the intersection point of 0 comes to the target point.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of a surveying instrument showing one embodiment of a surveying method using a display screen according to the present invention.

In the figure, a surveying instrument 1 is shown as an instrument body 2
A telescope 3 arranged on the front surface of the device body 2, a video camera 4 detachably attached to the eyepiece of the telescope 3,
A display screen 6 connected to the video camera 4 via a signal cable 5 and a sighting device 8 for roughly aiming a target point 7 are provided. Further, the display screen 6 is provided with a device 9 for adjusting the focus and illuminance of the screen.

Explaining the surveying method, first, the aiming device 8 roughly aims at the target point 7 to set the direction of the device body 2, and then the image obtained by looking into the telescope 3 is photographed. Then, the image is displayed on the display screen 6, and fine adjustment is performed while watching the screen so that the intersection of the crosshairs 10 on the display screen 6 comes to the target point.

[0010]

As is apparent from the above description, according to the present invention, it becomes possible to easily carry out the measurement work of the target point,
It is possible to reduce the surveying error and also to significantly reduce the eye fatigue in the surveying work for a long time, and to greatly improve the efficiency of the surveying work.
