Embodiment Construction

[0011] Calculate the non-displacement oil storage volume:

[0012] First study the cross-section of the tank body, and establish a coordinate system such as figure 1

[0013] The equation for the cross-sectional ellipse is:

[0014] When the liquid level is H, OO'=b-H, the coordinate of point A is (x 1 ,z 1 ),so where z 1 =OO'=b-H, easy to find

[0015] AB = 2 O ′ A = 2 x 1 = 2 a b 2 - ( a - H ) 2 b - - - ( 0.1 ...

Abstract

The invention discloses an oil mass calculating method based on point cloud data, relates to the fields of data processing and three-dimensional visualization, and invents a method which automatically calculates the volume of remaining oil mass in an oil tank in real time based on the point cloud data obtained by three-dimensional laser scanning equipment. The point cloud data obtained by the laser scanning equipment are preprocessed to obtain the real-time oil level height and the oil tank shape volume which are composed of point cloud data, and then the volume of the remaining oil mass in the oil tank is calculated. The set of complete data processing and oil mass calculation method is designed to monitor oil mass rapidly and accurately in real time, the method is not affected by changes of oil volume along with temperature, and rapid and reliable bases and means are provided for managing and dispatching an oil warehouse.

Description

Technical field: [0001] The present invention relates to the field of data processing and three-dimensional visualization. The three-dimensional point cloud data of the oil tank and the oil surface can be obtained quickly, dynamically and accurately through the three-dimensional laser scanner. After preprocessing, the volume and oil volume of the oil tank can be accurately calculated by the integral method Volume, thereby realizing the automatic collection, transmission, and storage of information, improving the automation and informatization level of the oil depot, and improving the management efficiency and safety level of the oil depot. Background technique: [0002] 3D laser scanning technology, also known as real scene replication technology, is a technological revolution in the field of surveying and mapping after GPS technology. It breaks through the traditional single-point measurement method and has the unique advantages of high efficiency and high precision. The 3D...
