Generally, laser scanning is your tool if you need a high level of accuracy over a large space. Photogrammetry is a better tool if you are documenting smaller spaces and are looking for less accuracy but more visual photo realism.
This is why photogrammetry is commonly used in the entertainment industry, such as for the creation of environments for games and movies. It is also being embraced by the archeological community because it allows for 3D documentation of individual objects with more realistic textures for a lower price than laser scanning.
Laser scanning on the other hand is more applicable to the architecture, engineering and construction industries because of its level of accuracy over a large distance.
Whenever there are multiple tools to get the job done we have to step back and weigh the differences. Accuracy, speed, costs, scale and the final use of the 3D data need to be considered when choosing between laser scanning and photogrammetry.
