SfM (Structure from Motion) photogrammetry offers great versatility in survey and restitution operations. The most important feature that allows this technique to be applied to a wide range of observation distances is the resolution of the images intended both as the quantity and quality of the pixels that compose them. With the same digital camera, equipped with a good sensor (CMOS) and operating in good light conditions, it is possible to acquire images over large or short distances with focal lengths that can vary between the extremes of wide angle and telephoto. Photogrammetry can thus be applied to elements of various sizes: from large structures such as slopes, land and buildings, to artifacts and even very small archaeological finds. It is therefore a question of using a...
