Low-voltage direct-current arc energy distribution visualization research method and device

The invention relates to a low-voltage direct-current arc energy distribution visualization research method and device, and the method comprises the steps of collecting the information of an arc, setting a preprocessing process of the collected information, carrying out the filtering operation and equalization processing of the electric parameters and image information of the arc, enhancing the image contrast, and removing the interference; determining the peripheral boundary of the arc by using an edge detection algorithm in an image processing technology; realizing simplified operation of the arc form by applying binaryzation; and monitoring the change trend of the area and the perimeter of the arc in the gap in the diffusion process by combining a morphological calculation principle. The two-dimensional energy and form distribution characteristics of the arc in the horizontal projection direction are visualized in the on-off process of the switching device. 本发明涉及一种低压直流电弧能量分布可视化研究方法及装置，通过采集电弧的信息，设立采集信息的预处理流
