Description

[Detailed description of the invention]

The present invention is a three-dimensional method that can be used to measure the position of a weight used in weight-type rubble leveling, the position of a caisson when installing a caisson, or the position coordinates of a survey vessel conducting bathymetric surveying. It relates to surveying equipment.

[Prior technology] Conventionally, a weight installed on a crane ship for leveling the rubble thrown in to install a caisson on the seabed, etc., and a survey of the three-dimensional position coordinates of the caisson when it is installed. In order to do this, for example, a light wave positioning and angle measurement device such as the product name Total Station is installed at a known fixed point, and a person takes a survey by collimating a reflective mirror installed at the measurement point. There is.

[0003] In recent years, automatic tracking positioning devices, such as the geodimeter (trade name), have been developed, which can automatically search for a measuring point without the need for a human to sight a reflective prism or the like placed at the measuring point. It helps save labor. however,
The automatic tracking positioning device uses light waves, so if there is a ship or other obstruction between the automatic tracking positioning device and the reflecting prism at the measurement point, the reflecting prism will be lost, so the light wave emitting part may be lost. There is a problem in that it takes time to find the reflective prism by rotating vertically and horizontally, and it takes time to find the reflective prism.Especially in construction work, there is a high possibility that there are obstacles. , there is a risk that the work will be interrupted, and the work efficiency will be reduced.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and it is an object of the present invention to provide a shield between an automatic tracking positioning device, etc., and a reflecting prism, etc. provided for measurement. The problem to be solved is to provide a three-dimensional surveying device that can immediately find the reflective prism even if an automatic tracking positioning device loses sight of the reflective prism due to the presence of an object, thereby improving work efficiency. be.

[0005]

[Means for Solving the Problems] As a means for solving the above problems, the three-dimensional surveying device of the present invention provides a method for collimating an automatic tracking positioning device or a light wave ranging and angle measuring device installed at a known fixed point. A video camera is attached to the window, and image data such as a reflecting prism or mirror of the measuring point sighted by the video camera and survey data of three-dimensional coordinates of the X, Y, and Z axes are provided at the measuring point. For example, data is sent to a computer and monitor TV in the cockpit of a crane ship, etc., and while watching the monitor TV, the data from the controller that is operated is sent to an automatic tracking positioning device or a light wave ranging and angle measuring device. It is configured by providing a transmission device.

Therefore, even if there is an obstruction between the collimation window of the automatic tracking positioning device and the reflecting prism of the measurement point and the reflecting prism is lost, the reflecting prism can be quickly found. .

First, in Fig. 1, an automatic tracking type positioning device 1, such as a product name geodimeter, or a light wave ranging and angle measuring device is installed using a tripod 2 at a known fixed point of a turret on land or at sea. A small video camera 3, preferably a CCD camera (charge-coupled device camera), is attached to a sighting window of the positioning device 1 or the like.

Further, a reflecting prism 4 is provided above the weight as a measurement point. Next, in order to transmit the image data collimated by the sighting window of the automatic tracking positioning device 1 and the survey data, that is, the three-dimensional coordinates of the X, Y, and Z axes of the reflecting prism 4 provided at the measurement point, The automatic tracking positioning device 1 and the transmission device 5A, preferably a parabolic antenna, such as a product name Pasolink, are connected by a cable.

On the other hand, in order to transmit data from a controller 8 such as a joystick type shown in FIG. 2 which is an enlarged view of the inside of a crane operating room 7 of a crane ship 6 to an automatic tracking positioning device 1, a transmission device 5A and a computer are used. 9 is connected by a cable, and further connected to the automatic tracking type positioning device 1 via a D/A (digital/analog) converter 21 and a controller 8 by a cable.

In addition, transmission devices 5A, 5B
uses one that has sending and receiving functions.

Furthermore, a gyro compass 12 is installed at an appropriate position on the hull of the crane ship 6, a rotation detector 13 is installed on the crane swivel platform of the crane ship 6, and a boom is installed at an appropriate position on the boom of the crane 6A. An angle detector 15 is installed. On the other hand, a monitor television 17 that displays images from the video camera 3 is installed in the crane operator's room 7, and the three-dimensional coordinates of the reflecting prism 4 measured by the automatic tracking positioning device 1 are also installed in the crane operator's room 7. and a computer 9 that calculates and displays the three-dimensional coordinates of the lower end of the weight 16 and the positions of the crane ship 6 and crane 6A from the data of the Shiro compass 12, the turning detector 13, and the boom angle detector 15. A CRT9A is installed.

Furthermore, an A/D converter 11 is installed in the crane operating room 7 to convert an analog signal from a controller 8 that controls the direction of the automatic tracking positioning device 1 into a digital signal.

In the three-dimensional surveying device configured in this manner, the location where the automatic tracking type positioning device 1 is sighted can always be confirmed on the monitor TV 17 in the crane control room 7, so that the automatic tracking type positioning device can be Positioning device 1 is reflective prism 4
Even if you lose track of it, you can immediately check it on the monitor TV 17.
The operator of the crane 6A can operate the controller 8 in the crane operating room 7 to control the collimation of the automatic tracking positioning device 1 and quickly locate the reflecting prism 4.

[0014] Therefore, the time from when the automatic tracking type positioning device 1 loses sight of the reflective prism 4 until it searches for it is shortened. Although this embodiment is explained using an automatic tracking positioning device 1, a small video camera 3 may be used in the collimation window of a light wave positioning and angle measuring device, such as a product name Total Station.
It is also possible to collimate the reflective prism 4 or the reflective mirror by attaching the camera and operating the light wave positioning and angle measuring device using the controller 8 while watching the monitor television 17 in the crane operating room 7.
