The invention relates to the technical field of visual detection, and discloses an elevator polyurethane buffer detection method based on machine vision, which comprises the following steps: a CCD visual sensing device is mounted at the bottom of an elevator shaft, the visual detection range of the CCD visual sensing device is adjusted, and port coding is performed according to the actual mounting position of the CCD visual sensing device; corresponding port codes are distributed to the elevator polyurethane buffer, and information collection comprises collection, signal transmission, information processing, user UI interaction and data storage of video signals in the compressed process of the elevator polyurethane buffer. During use, image extraction is carried out on the uncompressed state and the compressed state of the polyurethane buffer through the CCD visual sensing device, and the form variation of the polyurethane buffer under pressure is detected according to the extracted image, so that the performance detection of the polyurethane buffer can be completed without manual work, and compared with a traditional visual inspection method, the detection efficiency is greatly improved. The method is higher in detection precision.

    本发明涉及视觉检测技术领域,公开了一种基于机器视觉的电梯聚氨酯缓冲器检测方法,包括视觉传感将CCD视觉传感装置安装于电梯井道底部,并调节CCD视觉传感装置的视觉检测范围、端口编码根据实际CCD视觉传感装置安装位置,为其分配对应的端口编码、信息采集包括将电梯聚氨酯缓冲器被压缩过程的视频信号进行采集、信号传输、信息处理、用户UI交互、数据储存,本发明中,在使用时将会通过设置的CCD视觉传感设备对聚氨酯缓冲器的未被压缩状态以及压缩状态进行图像提取,并根据提取的图像检测其受压时的形态变化量,从而无需人工即可完成对聚氨酯缓冲器的性能检测,且相比于传统目测法,本方法的检测精度更高。
