The Quick Ortho Composite is a streamlined preset designed for the production of terrain-based orthophotos. Leveraging automatically extracted terrain data from PhotoMesh aerotriangulation results, it enables the generation of terrain-based ortho composites approximately 15 times faster than traditional True-Orthophoto methods. This method serves as an efficient visualization mode for rapid orthophoto production ahead of full 3D model completion. More about: Using presets >
Key Features:
- Utilizes terrain data extracted immediately after AT for quick orthophoto generation.
- The TIN (Triangulated Irregular Network) model is used for representing variable terrain density, with PhotoMesh selectively texturing the TIN from the necessary parts of photos.
- The process selectively textures individual triangles within the TIN, allowing for choice of photos based on the best perspective, resolution, and quality in a non-contiguous fashion.
- Acts as an expedited processing mode for producing preliminary orthophotos, ideal for initial visual assessments.
- Optimized geometry and texture from terrain-based rectification.
- Generates a very low-density point cloud to optimize image normals and resolution for ortho texturing.
- Employs a surface model that represents extracted terrain.
- Removes the need for mesh texturing, expediting the output generation process.
- Uses fuser architecture for parallel processing, crucial for handling I/O intensive steps and efficient ortho texturing.
- Offers unlimited scalability with the appropriate IT infrastructure, due to low geometry requirements.
Technical Requirements and Recommendations:
- The process is GPU intensive; thus, a dedicated GPU is recommended for optimal speed.
- A fast network connection and a high-performance NAS (Network Attached Storage) with high bandwidth and IOPS (Input/Output Operations Per Second) are crucial for maximizing efficiency.
