Latest Patents

Yanyan Cai holds a significant patent titled "Half-cast mark identification and damaged flatness evaluation and classification method for blastholes in tunnel blasting." This innovative method is comprised of several key steps. It includes photographing first and second contrast images, as well as a half-cast mark image, following blasting. The process subsequently involves denoising, gray-scale processing, and binary processing of these images to identify the boundaries of the half-cast mark. Additionally, Cai's method determines a flatness damage variable and establishes a quantitative relationship between the area of the half-cast mark region, the damage variable, and a fractal dimension. The innovation culminates in forming five-dimensional (5D) eigenvectors to extract multi-dimensional digital information features, allowing the use of a naive Bayes classifier for effective classification.
