Abstract: Various example embodiments provide a computer system of unsupervised learning with deep similarity for optical flow estimation and a method thereof. According to various example embodiments, the computer system may be configured to calculate deep similarity by using deep features extracted from a sequence of a plurality of images, and learn optical flow for the images based on the deep similarity. In other words, the computer system may learn deep learning model for estimating optical flow through unsupervised learning based on deep similarity for a sequence of a plurality of images. At this time, the computer system may learn optical flow by using a feature separation loss function obtained by dividing occlusion locations and non-occlusion locations on the deep similarity map.

Abstract: Disclosed are a method of inspecting and evaluating a coating state of a steel structure, and a system therefor. A plurality of vision images and thermal images are acquired. While acquiring the thermal images, a desired region is heated. After the thermal images and the vision images in a dynamic state are reconstructed into a time-spatial-integrated thermal image and a time-spatial-integrated vision image in a static state, respectively, an overlay image is generated by overlaying the two images. A deterioration region of a coating is detected, and coating deterioration is classified by characteristics. A size of the coating deterioration region is quantified. A thickness of the coating is inspected by analyzing thermal energy measured from the time-spatial-integrated thermal image. A coating grade is calculated by comprehensively evaluating a coating deterioration inspection result and a coating thickness inspection result. A state evaluation report for the steel structure is automatically created.
