Convert images into high-quality reality reconstructions
- 2D and 3D Reconstruction: Generate reality meshes, gaussian splats, RGB/thermal orthomosaics, as well as DEM/DSM and DTM. This process includes calibrating cameras, performing aerial triangulation, and utilizing ground control points to ensure precision in outputs.
- Data Compatibility: Supports RGB/thermal imagery, videos, image metadata, and lidar formats such as LAS, LAZ, OPC, and POD.
- Advanced Editing and Refinement: Enhance reconstructions directly using iTwin Capture Modeler Flex, free with your subscription.
- High-Performance and Scalability: Run multiple engines in parallel to accelerate complex jobs, ideal for city-scale infrastructure projects.
- Workflow Automation: Automate workflows end-to-end using the included software development kit.
Seamless Integration
- Integrates with iTwin Capture Modeler Flex to manage projects, navigate photos, and touch up outputs.
- Compatible with iTwin Capture Cloud Services for AI-powered cloud-scale processing.
About this software subscription: This Virtuoso Subscription includes a 12-month practitioner license of this software, that comes with Keys (credits) to unlock training and services.
Reality modeling
iTwin Capture Engine is Bentley’s next generation on-premise reality modeling processing engine for transforming photographs, lidar point clouds, or mixed-sensor datasets into accurate, high-fidelity and engineering-ready digital assets, Gaussian splats, reality meshes, point clouds, orthophotos, and digital elevation models.
High performance
Designed for professionals who need full control, high performance, and secure on‑premise processing, iTwin Capture Engine delivers the speed, scalability, and reliability required for demanding infrastructure projects. iTwin Capture Engine is built to handle complex datasets with ease from small projects to city-wide surveys. Run multiple processing engines in parallel across different machines to achieve faster results.
Hybrid processing
iTwin Capture Engine integrates seamlessly with iTwin Capture Modeler Flex and iTwin Capture SDK, both of which are available free of charge, to organize your reality modeling projects and productions. iTwin Capture Engine is also compatible with iTwin Capture Cloud Services, which offers cloud–scale processing and AI–powered analysis.
For infrastructure
From field data to engineering–grade outputs, iTwin Capture Engine delivers the performance you need to keep projects moving. Produce 3D models of existing conditions for infrastructure projects. These highly detailed 3D reality meshes provide precise real–world context for design, construction, and operations decisions throughout the lifecycle of an infrastructure.
Advanced Reality Modeling and Analysis
Descartes enhances the suite with a rich set of advanced tools to model, analyze, and extract more value from your reality data. It provides robust modeling features for creating and manipulating 3D geometry directly within the context of your reality data. The software enables the extraction of breaklines, contour lines, and DTMs from terrain, and provides powerful point cloud filtering and classification capabilities. With Descartes, you can create scalable meshes, perform volume calculations, generate cross-sections, and stream reality meshes from Reality management, with 3D PDF supported for output and interoperability.
