Photogrammetry is a reliable method for creating precise 3D models of real objects. Utilizing a turntable is a common practice in this technique to capture images of an object from various perspectives. Seeking to streamline the photogrammetry process with minimal human intervention, [Peter Lin] designed an automated turntable system.
In this setup, a smartphone is used to capture images of the physical object. An ESP8266 triggers the phone to take photos by activating the shutter through the phone’s audio port. Subsequently, a microcontroller rotates the turntable by a specific angle for a brief period after each photo is taken.
Although the system still requires repositioning of objects in different orientations on the turntable to capture all angles, the task of snapping photos and rotating the objects is now fully automated.
This build is valuable for individuals who frequently generate 3D models by imaging objects. The output from [Peter]’s setup showcases impressive results and realistic textures. Additionally, other remarkable photogrammetry projects have been previously demonstrated. Watch the video below for more details.
