Method for measuring tank car tank body volume using computer image analysis technology

Abstract

The invention discloses a method for measuring the volume of the tank body of a tank car by using a computer image analytic technique. An outline section image of the tank car and tank body is shot firstly, and then the long axis dimension of a practical tank body section and the total length of a tank body axial direction are measured, subsequently, the image can be processed by adopting an image element calculation method or a region area integration calculation method and the practical volume of a tank body is calculated. The measuring and operating method of the invention is simple and practical, the measuring speed is quick, the normal production operation of a usage unit is not influenced, the measuring accuracy is high, the investment is small and the cost is low, no pollution to the environment can be caused, and the water resource is not required to be consumed.

Description

1. Technical field [0001] The invention relates to a method for measuring the volume of the tank body of a tanker, in particular to a method for measuring the volume of the tank body of the tanker by using computer image analysis technology. 2. Background technology [0002] In recent years, with the rapid development of my country's highway construction, the logistics of various hazardous chemicals using tanker trucks has also increased rapidly year by year. However, due to the one-sided pursuit of economic interests by some tank car manufacturers and transport units, they often carry out "big tons and small labels" on the volume when manufacturing tanks, and the phenomenon of "overloading and exceeding the limit" during transportation and loading is very serious, resulting in various hazards in the transportation of hazardous chemicals. Accidents happen from time to time, and some accidents even caused very serious consequences. Therefore, it is one of the important measu...

Problems solved by technology

To carry out this work, a large amount of investment in the construction of measurement facilities is required

[0007] 2. There are a wide variety of media contained in this type of tanker, and most of them are flammable, explosive, toxic, and corrosive media. To achieve the discharge of sewage after measurement, the treatment technology is complicated, the investment in facilities is large, and the operating cost is high.

[0008] 3. If the measurement water is recycled, it will cause cross-contamination in the tank, which will affect the quality of the transported medium

[0009] 4. Some media are incompatible with water, and it is difficult to completely remove the residual water in the tank after measurement

[0010] 5. The time period used for measurement is long

However, these methods have the disadvantages of difficult purchase of equipment, complex operation techniques, and many factors affecting the accuracy of measurement to varying degrees, so it is difficult to be applied in the actual work of tank volume measurement.
