This application discloses a method and
system for selecting auxiliary waterway video surveillance point locations, relating to the field of waterway
transportation facility deployment and management technology. The method includes: determining potential areas for video surveillance equipment deployment on both banks of a target waterway based on vector surface format data; conducting a
suitability analysis of surveillance equipment deployment at various locations within the potential areas based on multi-source geospatial data to determine a waterway surveillance equipment deployment suitability map; determining initial deployment points for the video surveillance equipment based on the waterway surveillance equipment deployment suitability map and a preset deployment strategy; determining the line-of-
sight coverage of each initial deployment point on the target waterway based on surface
elevation data; and adjusting each initial deployment point based on its line-of-
sight coverage of the target waterway to determine the final auxiliary waterway video surveillance
point location scheme. This application improves the efficiency and accuracy of waterway surveillance equipment deployment.
