For reconstructing cultural heritage sites from photos and laser scans into detailed 3D models, RealityCapture is a great option. It can automatically generate 3D models, textured 3D meshes and orthographic projections from photos and laser scans. It's geared for reconstructing historical sites, monuments and buildings, so it's a good fit for cultural heritage preservation.
Another good option is Polycam, which offers a full 3D capture and creation system. Polycam can capture LiDAR scans, photogrammetry and 360-degree panoramas from mobile phones and web browsers, so it's accessible to people with varying levels of technical expertise. Its Pro tier adds higher-end features like automatic remeshing and texture baking that can be useful for creating detailed 3D models.
Matterport is worth a look, too, especially if you need to capture, collaborate and analyze 3D digital twins of real-world sites. The company's platform can capture 3D camera scenes and offer virtual tours, and it uses AI for analytics and integrates with construction and design tools like Procore and Autodesk. That can be useful for property marketing and facilities management in heritage preservation projects.
If you want to go full AI, 3DFY.ai generates high-quality 3D models from text prompts or single images. Its models have quad-meshed topology, high-quality UV maps and physically-based rendering materials, so it's good for a lot of heritage preservation work. Its speed and scalability can dramatically accelerate the creation of detailed 3D models.
