Creating 3D Data with Pixels to Points in Global Mapper Pro

Unlocking the Power of Pixels: Efficient 3D Data Creation with Global Mapper Pro’s Pixels to Points Tool

Sponsored Content.  The all-in-one geospatial software, Global Mapper Pro®, really does it all! From raster data viewing and editing to vector feature creation, Global Mapper Pro goes further to include tools for point cloud analysis and classification. The Pixels to Points® tool in Global Mapper Pro even enables users to create 3D data from overlapping drone/UAV-collected images.

The Pixels to Points tool uses an overlapping, geotagged image set as an input to generate a seamless orthoimage, point cloud, and textured 3D mesh. These outputs are created using structure from motion analysis, a process which creates very high-resolution data outputs. The use of surveyed ground control points in the Pixels to Points tool will help enhance the positional accuracy of the created data layers.

In Global Mapper Pro version 26.0, ground control points can be automatically identified, improving on the previous workflow that included the tedious task of individually tagging each control point in each image. Automatic ground control point placement uses the control point location and calculated image coverage polygon for each image to identify candidate images where a ground control point may appear. The user then identifies the control point target. This might be a manually placed target board, or a fixed and identifiable feature on the ground, such as a manhole cover. The user then asks the Pixels to Points tool to place the control point in all images where the target is found. The user can then adjust and confirm the control point placements as needed before running Pixels to Points to generate the high-resolution data outputs.

Global Mapper 26.0 also boasts a significant reduction in processing time in the Pixels to Points tool. Improvements and optimizations to the underlying processes in the Pixels to Points data creation process produced up to 50% improvements in processing time. Generating high-quality 3D datasets from drone/UAV-collected images makes Global Mapper Pro an even more valuable tool across many industries.
