The combination of the two techniques of photogrammetry and laser scan can have several advantages, depending on the type of project and the desired result. Examples include:

• Photogrammetry can be used to capture the colors and textures of objects, while laser scan can be used to obtain better precision and resolution of shapes and details.
• Photogrammetry can be used to cover large surfaces or complex objects, while laser scan can be used to complete missing or blurred areas, or to scan transparent, reflective or dark surfaces.
• Photogrammetry can be used to produce 3D models at lower cost and with lighter hardware, while laser scan can be used to produce more reliable and robust 3D models.

In order to combine the two techniques, there are software available to merge photogrammetry and laser scan data, such asiTwin CaptureBentley Systems. These softwares align, clean, mesh and texture reality data from different sources, and achieve a complete and homogeneous 3D model.
