Image cleaning and pre-processing services for visual databases

June 6th, 2019, Published in Articles: PositionIT

East View Geospatial (EVG) has a long history of working with high-resolution imagery to produce detailed elevation models for use in simulation software. The company’s in-house team of geospatial analysts are experienced in extracting and attributing features from imagery and other geospatial source data to ensure the most accurate datasets. EVG’s experience and expertise is leveraged in the company’s latest solution – image cleaning and pre-processing services. Using a proprietary workflow, the company works with high-resolution imagery (better than 50 cm) to suppress any distortions and remove any unwanted noise. Often this includes the removal of vehicles, shadows, people, and more. At the same time, features such as roads, parking lots, and crosswalks are extracted, digitised and rasterised on top of the source imagery to produce an image output optimised for use in 3D visualisation software. The company’s image cleaning and pre-processing services are highlighted in a recent collaboration with partner B-Design 3D, a independent provider of interactive 3D visual content for the training and simulation industry.
