Maintaining and monitoring energy infrastructure has become critical as global energy demand increases. Energy infrastructure refers to power stations, transmission and distribution networks, pipelines, windmills, solar farms and other amenities. This is very important for continuous energy provision, and safety, with consideration to efficiency and sustainability of the systems. Among modern technologies, computer vision can be considered one of the most promising tools in Energy Infrastructure monitoring as it significantly increases the speed of damage detection, decreases time spent on preventive actions, and improves the overall efficiency of operating processes. This blog discusses the historical background, innovation, use case, and future opportunities of utilizing computer vision in this area. 
A Brief History of Computer Vision
Computer vision is a more extensive branch of artificial intelligence technology that aims to help machines understand visual information. The idea was conceived in the 1960s when attempts were made to detect simple shapes in images. The pioneer systems were relatively simple, using only edge detection and simple pattern analysis algorithms.
Computer vision experienced technological breakthroughs in the 1990s and the beginning of 2000 when machine learning algorithms were developed and computation capability was enhanced. At the start of the decade, Convolutional Neural Networks (CNNs) were released, and a new real milestone for machines was established: achieving the same performance as humans around vision recognition. The engines of today’s vision systems are deep learning, enabling these systems to analyze enormous volumes of visual inputs in real-time. Computer Vision on Edge and its Applications.
