Through application research of new type fiber in the sports equipment field, understand its effects on sports equipments and advantages, and grasp its booster function in the improvement of development system and sport performance during the development process of sports equipments.
This paper concludes four points on relevant mechanisms of sports corresponding to technology: mechanism of technological innovation, mechanism of self-perfection, mechanisms of selection and codes of ethics. The mechanism of technological innovation provides external driving force to sports' agreement with technology, self-perfection mechanism provides internal driving force to their agreement and the mechanism of selection enables sports and technology to choose based on their own needs. While the mechanism of code provides theoretical basis and codes to the long-term sound development after sports corresponding to technology.
Paper proposes a method for detecting general obstacles on a road by subtracting present and past in road cycling camera images. The image-subtraction-based object detection approach can be applied to detect any kind of obstacles although the existing learning based methods detect only specific obstacles. To detect general obstacles, the proposed method first computes a frame-by-frame correspondence between the present and the past in-road cycling camera image sequences, and then registries road surfaces between the frames. Finally, obstacles are detected by applying image subtraction to the redistricted road surface regions with a vision insensitive feature for robust detection. Experiments were conducted by using several image sequences captured by an actual in-road cycling camera to confirm the effectiveness of the proposed method. The experimental results shows that the proposed method can detect general obstacles accurately at a distance enough to avoid them safely even with different situations.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
