Color consistency remains one of the most common challenges in aerial photogrammetric production. Variations caused by changing illumination, atmospheric conditions, seasonal differences, water surfaces, and large image blocks can make it difficult to achieve homogeneous results across an entire project.
To address these challenges, Vexcel Imaging has redesigned the automated color balancing workflow in UltraMap, introducing a new model-based approach that improves project-wide homogeneity while significantly reducing processing times.
These innovations will be the focus of an upcoming Tech Talk Webinar hosted by Vexcel Imaging’s photogrammetry experts.
Why color balancing matters
Color balancing is a critical step in the production of orthophotos and other geospatial data products. Inconsistent color tones, gradients, and visible transitions between images can negatively impact both the visual quality and usability of the final dataset.
As aerial acquisition projects continue to grow in size and complexity, achieving consistent color across thousands of images becomes increasingly challenging. Water bodies, oblique imagery, varying sun angles, and atmospheric conditions often introduce additional difficulties that require significant manual intervention.
A redesigned approach in UltraMap
The latest UltraMap release introduces a fundamentally redesigned color balancing workflow.
Instead of relying solely on traditional methods, the new model-based approach analyzes image characteristics across the project to achieve improved consistency and more homogeneous results.
Key benefits include:
- Improved project-wide color homogeneity
- Reduced gradients and color inconsistencies
- Enhanced balancing of water bodies
- Better radiometric integration of oblique imagery
- Up to 2x faster processing
- A fully automatic workflow
The result is a more seamless image block with less manual effort and faster turnaround times.
Join the webinar
During this Tech Talk Webinar, Vexcel experts Bernhard Schachinger and Marc Muick will provide an in-depth look at the new color balancing workflow. They will demonstrate how the redesigned approach improves both efficiency and output quality and share practical recommendations for capturing more homogeneous datasets under real-world operating conditions.
Attendees will learn:
- How the new model-based workflow works
- How UltraMap improves project-wide homogeneity
- How challenging surfaces such as water can be handled more effectively
- How processing times can be reduced by up to 50%
- Best practices for achieving consistent results across large-scale projects
A live Q&A session will conclude the webinar, giving participants the opportunity to discuss their specific challenges directly with Vexcel experts.
