Problems solved by technology

When the crane is in operation, under the traction of the crane arm, the heavy hammer and hanging objects will move at a certain speed. At the same time, there will be moving obstacles such as pedestrians and UFOs on the work site. Collision between objects and obstacles is likely to have a great impact on the crane and obstacles, and even cause the crane to overturn
In addition, the external environment such as wind will also interfere with the work of the crane, which also greatly threatens the safety of the crane operation.
[0004] Aiming at the safety problem of cranes, people have conducted in-depth research and installed various protective devices on...

Embodiment 1

[0055] figure 1 It is a flow chart of the crane obstacle monitoring and early warning method provided by the present invention.

[0056] The binocular vision-based crane obstacle monitoring and early warning method provided by the present invention includes the following steps:

[0057] Step 101: Build a binocular vision model and initialize relevant parameters. In order to accurately describe and analyze the status information of space objects, it is necessary to establish a binocular visual coordinate model, mainly including the world coordinate system, camera coordinate system, imaging coordinate system and pixel coordinate system; at the same time, the relevant data should be initialized, that is, obtained through camera calibration The internal parameters of the camera, the baseline distance is obtained through measurement or pre-setting, and the world coordinate system is initialized through other devices (such as the positioning system of the bridge crane), so as to de...

Abstract

The invention discloses a crane barrier monitoring and prewarning method and system based on binocular vision. The method includes the steps that a binocular vision model is established, and relevant parameters are initialized; images are acquired in real time and preprocessed; target edges are detected, and the characteristics of the images are extracted; the left images and the right images are registered, and a common area is segmented; iteration is repeatedly conducted, and foregrounds and backgrounds are distinguished; three-dimensional information is rebuilt, and the foregrounds and barriers are recognized; motion parameters are resolved, and prewarning information is analyzed and output. According to the crane barrier monitoring and prewarning method and system, a binocular vision system is adopted, the working environment of a crane is monitored in real time, the problem of preventing collision of the crane is effectively solved, and the system has the advantages of being high in efficiency, moderate in accuracy, simple in structure, low in cost, and very suitable for online, non-contact product detection and quality control on a manufacturing site.

Description

technical field [0001] The invention relates to a crane obstacle monitoring and early warning method and system based on binocular vision. Background technique [0002] The hoisting machinery industry provides a variety of hoisting machinery and equipment for my country's metallurgy, mining, railway, shipbuilding, transportation, water conservancy and electric power industries, and is an indispensable industry in the construction of the national economy. Crane is a kind of hoisting machinery, which is a kind of machinery for cyclic and intermittent movement. Now it has been widely used in various industries of people's life, providing more convenience for people. [0003] At present, the real-time and safety of the crane is one of the hot issues of widespread concern. When the crane is in operation, under the traction of the crane arm, the heavy hammer and hanging objects will move at a certain speed. At the same time, there will be moving obstacles such as pedestrians and ...
