[0002] In the field of geological disaster monitoring and assessment, the measurement of cracks has always been a crucial link. Parameters such as crack width, length, and depth are not only key indicators for assessing the risk of geological disasters, but also an important basis for formulating disaster prevention and mitigation measures.
