以下、具体的な土量の測定方法を説明する。<Industrial Application Field> The present invention relates to a method for measuring the loading capacity of an earth transport vessel, which allows the loading capacity of a large amount of earth and sand to be determined accurately in a short time. <Conventional technology> As a method of measuring the amount of loaded earth and sand loaded on an earth transport ship, multiple workers stand on the loaded earth and sand on the ship, measure the level of the loaded earth and sand, and calculate the average of the loaded earth and sand. There are known methods such as finding a cross section and converting it from this average cross section, and calculating it from the water depth of the ship. Problems to be Solved by the Present Invention> The method of measuring the loading amount of a large amount of earth and sand described above has the following disadvantages. (b) With the former measurement method, there is a risk of workers falling during surveying work. Moreover, since the average cross-section method is used to make analogies based on data obtained from a small number of measurement points, there is a problem in that the accuracy of measuring the amount of loaded soil is low. (b) In the case of the latter measurement method, it is easily affected by the rocking of the ship (there remains a problem with the reliability of measurement accuracy. (c) Both measurement methods require a long time to complete the measurement. , it takes time to obtain the final loading amount of earth and sand.Purpose of the present invention> The present invention has been made in view of the above points, and it is possible to ensure the safety of workers and to Accurate measurements can be obtained,
The purpose of this study is to provide a method for measuring the loading capacity of earth carriers. <Structure of the present invention> Hereinafter, a method for measuring the loading capacity of an earth carrier according to the present invention will be explained. (a) Measurement principle The present invention performs measurement using photogrammetry. That is, two cameras are installed at fixed positions on the sea, and the earth transport ship located directly below these cameras is photographed. The three-dimensional photographs taken of the soil transport ship are input into an analysis plotting device connected to a computer, and the three-dimensional images reproduced within this device are analyzed in general, and the amount of sediment for each cross section is integrally calculated. This is the way to find out. (b) Measuring method The specific method for measuring soil volume will be explained below.

各その土量の積分計算により求めることができる。In FIG. 1, reference numeral 1 denotes a pedestal that protrudes above the water, and its lower end is supported on the seabed 3 by support legs 2. A known surveying table may be used as the pedestal 1. A boom 4 extends obliquely upward from the pedestal 1, and is configured to be tiltable in the vertical direction and pivotable in the horizontal direction. Two sets of cameras 5 are attached to the tip of the boom 4 facing downward. The installation interval and the installation direction of the cameras 5 are set according to the conditions under which stereoscopic photographs can be taken. Then, an earth transport vessel 7 loaded with earth and sand 6 is guided onto the water below the camera 5. Without moving the boom 4, the whole of the soil transport vessel 7 is photographed from diagonally above or directly above the soil transport vessel 7. When photographing the soil transport ship 7, the date and time of photographing, the hull number, etc. are also imprinted. If the soil transport vessel 7 is large, the camera 5 may be installed at a high place to photograph the entire soil transport vessel 7, but it is more rational to photograph the soil transport vessel 7 in parts. When photographing in parts, it is convenient to install one or more reference points or marker points on the earth transport vessel 7 at predetermined intervals in order to maintain continuity between the data taken in parts. be. If you set a reference point on the soil transport ship 7, based on this reference point,
It can be determined by integral calculation of each soil volume.

接記憶させる。Next, the photograph taken with the camera 5 is taken using a known analysis plotting device (
For example, set it on a branicomb C100) and capture the earth and sand 6 loaded on the earth carrier 7 as mesh data,
Measure its height. The number of height measurement points varies depending on the size of the earth carrier 7, but as shown in Fig.
Any score between 0 and 200 is sufficient. Points indicated by crosses in FIG. 2 mean measurement points. This height measurement is performed using a reference point displayed in advance on the earth transport vessel 7 as a height reference. The three-dimensional data obtained in this way is directly stored in the computer.

することができる。Next, the amount of soil for each mesh is determined from the mesh data, and these are summed to obtain the total amount of soil 6 loaded. It should be noted that, if necessary, mesh diagrams, sectional views, etc. as shown in FIG. 2.3 may be printed out. Effects of the Present Invention The present invention provides the following effects from the above. (b) Since the amount of earth and sand loaded can be measured without workers having to go up and down the earth transport vessel, safety for the workers can be ensured. (b) Since images are taken instantly, measurements can be made without being affected by the rocking of the ship. (c) The present invention is 1/3,000-115,0 of the shooting distance.
It is possible to measure with a high precision of 0.00, and moreover, uniformity of precision can be maintained. (d) Photographs taken of loaded earth and sand or analyzed data can be recorded and stored, so they can be used as objective materials in case of doubts.
