Embodiment 1

[0071] The present embodiment is based on the situation of adopting a scanner, and the specific method is as follows:

[0072] The first method: sector area scanning method

[0073] This method uses a single laser radar scanner to perform high-speed linear scanning based on the 360°C rotation of the pan-tilt, and then sends the data to the industrial computer for processing and calculation in combination with 3D modeling, and finally obtains the volume of the vehicle-mounted materials.

[0074] Establish vehicle-mounted material pile body coordinate system

[0075] Based on the 360°C rotating scanning of the pan / tilt, it is equivalent to treating the vehicle-mounted materials as a circular pile.

[0076] Based on the measurement principle, a three-dimensional coordinate system for yard calculation is established. First, establish the yard measurement plane coordinate system XOY. The plane coordinate system is established according to the yard envelope rectangle at the measur...

Embodiment 2

[0091] This embodiment is based on the situation of using two scanners, and the specific method is as follows:

[0092] image 3 Among them, scanner 1 is used for longitudinal scanning of the vehicle, and scanner 2 is used for horizontal scanning of the vehicle.

[0093] Taking the tail of the vehicle compartment as the coordinate origin, the vehicle displacement as the X coordinate, the vehicle width as the Y coordinate, and the height of each point in the data frame obtained by scanning the vehicle horizontally by the scanner as the Z coordinate, a three-dimensional coordinate system is established, combined with three-dimensional modeling, respectively Calculate the volume of the vehicle when it is fully loaded and empty, and finally get the material volume.

[0094] 1. X coordinate - vehicle displacement

[0095] The scanner 1 is used to dynamically scan the top area of ​​the vehicle longitudinally, and the system calculates the vehicle displacement according to the scan...

Embodiment 3

[0107] The present embodiment is based on the situation of adopting three scanners, and the specific method is as follows:

[0108] In the figure above, S1, S2, and S3 represent three laser radar scanners respectively, and the relative positions of the three sensors are shown on the left side of the figure, and the scanning principle is as follows Image 6 As shown in , where S1 and S2 are responsible for scanning the section of the vehicle, and S3 is responsible for scanning the length of the vehicle.

[0109] This method can scan the length, width and height of the vehicle, and calculate the volume and 3D graphics of the vehicle:

[0110] 1. S1 and S2 scan the interface of the vehicle from the top of the two sides to ensure that there is no shadow on the interface;

[0111] 2. Convert all the scanning points contained in the vehicle outline obtained by the sensor scanning into the coordinate points of the coordinate system, and record their coordinate X values ​​and Y value...

Abstract

The invention relates to a fixed type automatic volume measurement system and a measuring method of the fixed type automatic volume measurement system. The fixed type automatic volume measurement system is an automated measurement and calculation system based on multi-sensor integration. According to the system, multiple sensors are mainly used for synchronous control of a collector, a control tag reader and a high-speed laser scanner, and are in synchronous communication with an industrial personal computer to achieve data collection. Collected data are processed primarily by a controller to filter invalid data and transmitted to the industrial personal computer rapidly after being marked in a real-time mode with timing marks. A three-dimensional coordinate is computed through calculation processing software running in the industrial personal computer and by aid of the three-dimensional coordinate computational algorithm, vehicle-mounted material stack body modeling is carried out by combining the three-dimensional modeling algorithm, and then the volume of vehicle-mounted materials to be measured is calculated. Therefore, the fixed type automatic volume measurement system and the measuring method of the fixed type automatic volume measurement system have the advantages that a traditional method that a material transport vehicle is guarded all day long and recorded manually is replaced by a method that the material transport vehicle can be identified quickly and automatically, the volume of the vehicle-mounted materials can be measured quickly and accurately, and the material transport vehicle and the materials can be managed effectively.

Description

technical field [0001] The invention relates to a volume measurement system and its measurement method, in particular to a fixed automatic volume measurement system and its measurement method. Background technique [0002] For enterprises that need to buy or sell large quantities of bulk cargo such as sand, coal, ore, etc., large vehicles are often used to carry bulk materials, and then transactions are carried out according to the volume of the vehicle-mounted materials. [0003] There are generally several methods for obtaining the volume of vehicle-mounted bulk materials: (1) The material volume is artificially estimated based on the carrying capacity of the vehicle compartment and the material loading situation. This method needs to know the rated carrying capacity of the compartment of different vehicles, and the actual material loading of the vehicle The quantity is random, so the accuracy of this method is low and human factors are large; (2) The volume of the materia...
