Computer vision systems and methods for detecting power line hazards from imagery

Abstract

Computer vision systems and methods for detecting power line hazards from imagery are provided. The system obtains at least one image from an image database having an object and/or a structure present therein, and generates a digital surface model (DSM), a vegetation mask, and a three-dimensional (3D) power line model based on the obtained image. The system generates a digital line model based on the 3D power line and a risk distance indicative of a distance between the 3D power line and vegetation proximate to the 3D power line, and also generates a digital tree model. The system generates a digital difference model based on an intersection of the digital line model and the digital tree model, identifies sections of a power line within a risk distance of vegetation located proximate to the power line based on the digital difference model, and generates a vegetation risk report based on the identified sections of the power line, the predetermined 2D risk distance, a predetermined 3D risk distance, and an elevation risk distance.
