It depends on what you're planning to do with the scans. There are some great off the shelf photogrammetry and structure-from-motion apps out there, many free. There are also more involved tools that include depth sensors, lidar, or custom scanners. Unreal has a tool for making 3D scans into usable 3D models called realitycapture.
My advice is to nail down what you're trying to do, end to end, which will help you narrow the field of what to use.
