TL;DR: The effectiveness of this technique can be used to successfully detect cracks near bolts and the extracting of images of damage sensitive areas from different angles to increase detection of damage and decrease false-positive errors.
Abstract: The visual inspection of bridges demands long inspection time and also makes it difficult to access all areas of the bridge. This paper presents a visual-based crack detection technique for the automatic inspection of bridges. The technique collects images from an aerial camera to identify the presence of damage to the structure. The images are captured without controlling angles or positioning of cameras so there is no need for calibration. This allows the extracting of images of damage sensitive areas from different angles to increase detection of damage and decrease false-positive errors. The images can detect cracks regardless of the size or the possibility of not being visible. The effectiveness of this technique can be used to successfully detect cracks near bolts.
TL;DR: A meta-analysis of research on the relationship between inspection time and intelligence was performed to determine whether a nonzero relationship between IT and IQ exists, estimate the size of this relationship if it exists, and test whether IT is ontogenetically related to g.
TL;DR: Stough et al. as discussed by the authors introduced the inspection time measure to the wider psychological community and argued that inspection time, because of its much-replicated correlation with 1Q and its potential for theoretical tractability, has more potential for understanding individual differences in cognitive ability than other indexes of human information process- ing.
Abstract: Ian J. Deary Con Stough I I The purpose of this article is to introduce the inspection- time measure to the wider psychological community. In- spection time is, to date, the only single information- processing index that accounts for approximately 20% of intelligence-test variance. We argue that inspection time, because of its much-replicated correlation with 1Q and its potential for theoretical tractability, has more potential for our understanding of individual differences in cognitive ability than other indexes of human information process- ing. The nature of inspection time and its measurement are described, studies correlating inspection time and IQ- type test scores are summarized, and the difficulties of explaining this correlation are highlighted.
TL;DR: To capture stable, high-quality images of the lining surface as the raw data of inspection, an image capture system is well designed based on CCD (Charge-coupled Device) camera scanning and a new algorithm based on the features of the local image grid is developed to recognize cracks.
