Embodiment Construction

[0040] Figure 1 to Figure 5 A specific embodiment of the method for measuring the volume of the sand carrier of the present application is shown, which includes the following steps:

[0041] S1: When the sand transport ship is in an empty state, the collectors carry a backpack-type 3D laser scanner and walk around the cabin of the sand transport ship for a week, so as to collect the point cloud model of the sand transport ship when it is empty, such as figure 1 . Then, the volume V1 from the bottom of the ship to the starting datum 4 is calculated through the earthwork calculation function of the Lidar360 point cloud computing software.

[0042] In order to ensure the collection quality of the point cloud model, the collectors need to keep a uniform pace when walking with a backpack-type 3D laser scanner, and the transition should be smooth when turning and going up and down slopes.

[0043] refer to Figure 4 As shown, the above-mentioned starting datum 4 is calibrated in...

Abstract

This application discloses a method for measuring the volume of a sand transport ship, which includes the following steps: S1: The mobile 3D laser scanner walks around the cabin of the sand transport ship for a week, collects the point cloud model of the sand transport ship when it is empty, and passes the point cloud The calculation software calculates the volume V1 from the bottom of the ship to the starting reference plane; S2: The mobile 3D laser scanner walks around the cabin of the sand transport ship for a week, collects the point cloud model of the sand transport ship when it is loaded, and calculates it through the point cloud calculation software The volume from the upper surface of the sand to the starting datum level, where the volume of the part of the upper surface of the sand lower than the starting datum level is V2, and the volume of the part of the upper surface of the sand higher than the starting datum level is V3; S3: Calculate the sand-carrying volume V of the current sand transport ship =V1+V3-V2. The application can solve the problems of long measurement and calculation time, low measurement accuracy, and unsatisfactory information management in the prior art of manual measurement.

Description

technical field [0001] The application relates to the field of engineering measurement, in particular to a method for measuring the volume of a sand carrier. Background technique [0002] In sea reclamation projects, sand and gravel are the main building materials and the main component of construction costs. Therefore, whether the accurate measurement of sand and gravel directly affects the profit and loss of the project, while traditional manual measurement is affected by measuring instruments, human factors, and calculations. The impact of the means, the error is relatively large. How to accurately measure the square volume of the sand ship is an urgent problem to be solved. Contents of the invention [0003] The purpose of this application is to propose a measurement method for the volume of a sand carrier to solve the problems of long measurement and calculation time, low measurement accuracy, and inability to meet the requirements of information management in the ex...
