What is the difference between photo 3D model and Lidar scanning 3D model?

Photo 3D models are created from overlapping 2D images using photogrammetry, while Lidar scanning 3D models use laser pulses to capture precise spatial data. Photo models excel at texture and realistic visual detail—ideal for product design, landmarks, or scenes where appearance matters. Lidar prioritizes accurate geometry, making it better for surveying, construction, or terrain mapping where exact measurements are key. Choose photo 3D for visualization (like virtual tours) and Lidar for projects needing precise dimensions (such as building surveys).
