Problems solved by technology

Disadvantages of patent CN106460372A: multiple laser radars are used to scan the excavation surface around the excavation equipment, and each point in the scanned multiple images is collected to determine the shape of the excavation surface, and the materials in the excavation path are blocked by the excavation auxiliary equipment. Encoders and other equipment need to be used to record the excavation path, points in the excavation path need to be eliminated, and the calculation process is complicated
Disadvantages of the patent CN103900669B: the sensor of this patent uses an inclination sensor, a gyroscope, and a pressure sensor to connect with the data acquisition module. Influence

Embodiment Construction

[0053] to combine figure 1 , in order to achieve the above object, an excavator bucket material volume and weight measurement system includes at least one multi-line laser radar, a computing device, a manipulation display device and a preprocessing device.

[0054] The multi-line laser radar is used to scan the 3D point cloud of the bucket containing the material, and the scanned original 3D point cloud data containing information such as the ground, the boom, the stick, and the bucket through the communication link ( such as Ethernet) to the computing device.

[0055] The computing device is used to receive the empty bucket three-dimensional point cloud data and empty bucket volume obtained by the preprocessing device through a communication link (such as USB or Ethernet); receive multi-line laser radar scanning through a communication link (such as Ethernet) Obtained original 3D point cloud data containing buckets containing materials; through a series of algorithm processi...

Abstract

The invention relates to an excavator bucket material volume and weight measuring system, which belongs to the technical field of hydraulic excavator bucket weighing, and comprises a laser radar, a calculating device, a preprocessing device and an operation display device. According to the invention, a laser radar device is used for realizing dynamic volume and weight measurement of materials in the bucket in the operation process of the excavator; effective three-dimensional modeling can be carried out on the empty bucket, point cloud registration fusion is carried out on the bucket filled with materials in the later excavation operation process, the limitation that point cloud data acquisition is blocked by objects and thus point cloud acquisition is incomplete is solved, the measurementprecision is improved, and the complexity of the measurement device is reduced.

Description

technical field [0001] The invention relates to a bucket material volume and weight measurement system based on laser point cloud, and belongs to the technical field of hydraulic excavator bucket weighing. Background technique [0002] Excavators have a wide range of applications, and they can perform different tasks with different devices. In open-pit mining projects, excavators can strip the surface of minerals to complete the excavation and loading and unloading of minerals. Especially when the excavator is loaded with a truck, if the weight of the excavated material can be known, it can prevent the truck from being overloaded or underloaded and complete accurate loading. These data can also be recorded for construction data, and according to the statistical analysis of construction data, excavators can be allocated and dispatched reasonably to improve production efficiency. [0003] Patent CN106460372A, method and system for the actual responsible weight of mining exca...
