Method for Generating Regions of Interest Based on Data Extracted from Navigational Charts

A method for extracting data from a single-layer raster navigational chart (RNC) comprising: using a computer vision algorithm to extract color, text and symbol data from the RNC, storing the color, text, and symbol data in a database, and building an RNC data vector based solely on the color, text,...

description	A method for extracting data from a single-layer raster navigational chart (RNC) comprising: using a computer vision algorithm to extract color, text and symbol data from the RNC, storing the color, text, and symbol data in a database, and building an RNC data vector based solely on the color, text, and symbol data of the RNC, wherein the RNC data vector identifies geographical features shown in the RNC and a location of the geographical features' corresponding pixels in the RNC; and drawing a region of interest on the navigational chart based on user input and the RNC data vector, wherein a perimeter of the region of interest is georeferenced with latitude and longitude information.
