Week 3 - 3D Printing the Unmachinable and Scanning the World


Posted by Jordan Kennedy on October 3, 2017

Objectives:

  1. 3D Print the Unmachinable

Shown here a valve for my Gold Fish race track in order to control the flow.

This is a part within a part. The outercase rotates about the center. This controls the surface area of the valve.

The valve has a thread to connect to a purchased piping.

Here is the 3D printed piece.

2: Scan and Render in 3D

To get these images I flew drones over beaver damming sites in northwestern Montana.

The drones flown were a DJI Phantom and a Parrot Bebop Drone.

DJI

Bebop

The drones outputed MP4 video which I then converted into JPG files.

I used these JPG images and inputed them into Agisoft Photoscan. This is NOT a user friendly software.

  1. Unique JPG images were loaded into the software.

SitePhoto

  1. Photo’s were aligned.

Aligned

  1. The aligned photos were then meshed.

Mesh

  1. Texture was applied to the resulting texture.

Texture

Show here is the full rendering. It consists of 548 unique photos and represents an area approximately 1/2 mile long. Completed

Shown here are Batches consisting of 16 photos each. These batches are then combined for the final rending. The final rending has around 16 batches.

Shown below is the raw processing data required to make the completed rendering.

Shown here is a video of the raw data. For whatever reason, it only plays in Window’s Explorer.
