Possibly your objective is to protect the heyday of rail journey with a exact scale duplicate of a specific railroad station. Possibly you’re making a hyper-local version of Monopoly during which the homes and accommodations are the precise homes and accommodations in your hometown.
Regardless of the purpose, if in case you have want for shrinkifying a constructing or different fairly massive object, there’s (no less than) one sure-fire solution to do it, and [ nastideplasy ] is your information with this tutorial on drone photogrammetry.
The method is actually the identical as another photogrammetry you could have seen earlier than—take a number of overlapping images of an object from many various angles round it, sew these images collectively, make a 3D mesh by triangulating corresponding factors from a number of images—however this time the images are captured by drone, permitting for a lot bigger topics, as long as you’ll be able to safely and legally fly a drone round it.
The problem, after all, is capturing a ample variety of overlapping images such that your reconstruction software program can course of them right into a clear 3D mesh. The place purpose-built 3D scanners, computerized turntables, or a gradual hand and many persistence labored properly at a smaller scale, talent with a pair of management sticks is the important thing to getting scan of a home.
[ nastideplasy ] additionally factors out the significance of lighting. Direct daylight and deep shadows may cause points when processing the photographs, and doing this at night time is nearly definitely out of the query. Overcast days are your finest guess for a clear scan.
The tutorial requires software program from Autodesk to sew images and clear up 3D meshes. We’ve additionally seen some glorious outcomes with open supply choices like Meshroom as properly.
