The invention relates to a hazardous chemical substance storage stacking picture sample generation method and system. The method comprises the following steps of acquiring a first number of real picture samples of hazardous chemical substance storage stacks; carrying out GAN algorithm processing on the first number of real picture samples to obtain a second number of generated picture samples of the hazardous chemical substance storage stacks; and performing edge feature extraction, corner detection and noise filtering on the second number of generated picture samples, so that the sample distribution of the generated picture samples is close to the sample distribution of the real picture samples. According to the technical scheme, a large number of picture samples are generated by adoptinga GAN algorithm; the corner point extraction and the noise filtering are carried out on the generated picture sample; the sample distribution of the generated image samples is close to sample distribution of real image samples, the algorithm has important research significance on subsequent needed stereo matching, distance monitoring and three-dimensional reduction of hazardous chemical substancemonitoring, and powerful technical support is provided for visual ranging in a hazardous chemical substance warehouse on the samples.
