The three levels that the photos were taken from are more obvious in this photo. The photo above shows the flight path each blue square is a photo that was taken. If it cannot be done, try to change your shutter speed to something like 1/1000th of a second to reduce the “noise” which causes the blurring effect. Moreover, to reduce the blur effects that can occur in photos when using a drone, make sure to check if your camera will allow you to turn off the image stabilization. Doing this will reduce your chances to encounter these issues. To reduce the amount of correction your 3D model may need because of changes in the lighting, go out on a day when the lighting is consistent which is typically an overcast or cloudy day. When I asked Jeff if there are certain issues that can affect the results of the scan due to the use of a drone, he let me know that changing light, dark shadows and lens flares can be an issue. So as the drone completed one circular pass around the statue the camera was able to collect approximately 30-40 photos. The camera on his drone was set to take photos every 2-3 seconds. He set the center point at the top of the statue’s head and moved it back by about 82 feet (25 meters), and that’s where he set his radius. Jeff used the “point of interest” setting on his drone which allows the drone to automatically circle the statue while taking pictures of it. However, this tutorial will work for both professionals and beginners.

We’re going to use a process called photogrammetry, which is the process of collecting a group of points from a series of photos. If this is your first time attempting to use photogrammetry & additive manufacturing you may want to check out our blogpost “ Turning a picture into a 3D model” as it provides more detail regarding how photogrammetry works. Jeff Cremer’s occupation requires him to use professional grade equipment. Jeff shared with us his method for capturing the 100+ photos.īefore we share the steps to create scan files for large items using a series of photos, we think it’s important to talk about the process behind this type of “3D scanning”.

We talked to wildlife photographer Jeff Cremer about how he used a DJI Phantom 3 Pro drone, a camera and a modeling software to create a replica of a statue of Christ of the Pacific, on a hill in the capital Lima, Peru. Using a drone to take photos when scanning large items is becoming a more common practice in 3D printing.
