The invention relates to the technical field of crane safety control, and discloses a crane safety control system based on computer vision, which comprises an acquisition unit, a processing unit, an analysis unit, a center unit, a monitoring unit, a calculation unit and a management unit, the processing unit receives the image data information and carries out graying processing, and the analysis unit receives the image data after graying processing; two triangles are generated at the moment by collecting image data information when the lifting rope swings, a cube is formed by the bottom edges of the two triangles and the heights of the triangles, a triangle is generated by the center line of the vertex of the cube and two opposite vertexes of the bottom face at the moment, and the triangle is the actual swinging track of the lifting rope. At the moment, the angle beta of the vertex angle of the triangle is the actual swing angle of the lifting rope, the angle beta is compared with the swing value B, then prediction is conducted, and the safety of the crane is guaranteed.

    本发明涉及起重机安全控制技术领域,且公开了基于计算机视觉的起重机安全控制系统,包括采集单元、处理单元、分析单元、中心单元、监测单元、计算单元以及管理单元,所述采集单元采集起重机工作时的图像数据信息,所述处理单元接收图像数据信息并进行灰度化处理,所述分析单元接收灰度化处理后的图像数据;本发明通过采集吊绳摆动时的图像数据信息,此时会生成两个三角形,以两个三角形的底边以及三角形的高组成正方体,此时长方体顶点的中线与底面的两个相对顶点生成三角形,即为吊绳的实际摆动轨迹,此时该三角形顶角的角度β即为吊绳的实际摆动角度,该角度β与摆动值B进行对比,进而进行预测,保证起重机的安全性。
