Miss Nothing With A Hacked 360 Degree Camera Trap

October 18, 2019 by Danie Conradie 4 Comments

Camera traps are a very common tool in wildlife conservation and research, but placing and pointing them correctly can be a bit of a guessing game. Something very interesting could happen just out of frame and you’d be none the wiser. The [Andrew Quitmeyer] and [Danielle Hoogendijk] at DINALABS (Digital Naturalism Laboratories) in Panama are experimenting with hacked consumer 360° cameras to help solve problem.

The project is called Panatrap and looks very promising. They’ve done very detailed testing with a number of different 360° cameras, and have built functional prototypes with the Xiaomi Misphere and Ricoh Theta V. The Xiaomi had some handy contacts on the bottom of the camera for its selfie stick interface (simply a resistor and button), which allowed full control of the camera. An Arduino compatible board waits for the motion detected signal from a PIR sensor which then sends the required command to the camera to wake-up and take footage. The Ricoh was slightly more challenging, but they discovered that the camera will wake up if an emulated keyboard command is received over it’s USB port from a Teensy. Triggering is then done by a servo pushing against the camera’s button. Everything is housed in a laser cut acrylic case to help it survive the wet jungle. If anyone knows how to hack the Samsung Gear camera to work, the team is keen to hear from you!

All the work is open sourced, with build details and hardware designs available on the project page and software up on Github. Check out some cool 360° test footage after the break with some local wildlife. We are looking forward to more footage! Continue reading “Miss Nothing With A Hacked 360 Degree Camera Trap” →

Shoot Video In 26 Different Directions

May 31, 2017 by John Baichtal 9 Comments

[Mark Mullins] is working on a project called Quamera: a camera that takes video in every direction simultaneously, creating realtime 3D environments on the fly.

[Mark] is using 26 Arducams, arranging them in a rhombicuboctahedron configuration, which consists of three rings of 8 cameras with each ring controlled by a Beaglebone; the top and bottom rings are angled at 45 degrees, while the center ring looks straight out. The top and bottom cameras are controlled by a fourth Beaglebone, which also serves to communicate with the Nvidia Jetson TX1 that runs everything. Together, these cameras can see in all directions at once, with enough overlap for provide a seamless display for viewers.

In the image to the right, [Mark] is testing out his software for getting the various cameras to work together. The banks of circles and the dots and lines connecting to them represent the computer’s best guess on how to seamlessly merge the images.

If you want to check out the project in person, [Mark] will be showing off the Quamera at the Dover Mini Maker Faire this August. In the meantime, to learn more about the Jetson check out our thorough overview of the board.

Taking First Place At IMAV 2016 Drone Competition

January 10, 2017 by Donald Papp 1 Comment

The IMAV (International Micro Air Vehicle) conference and competition is a yearly flying robotics competition hosted by a different University every year. AKAMAV – a university student group at TU Braunschweig in Germany – have written up a fascinating and detailed account of what it was like to compete (and take first place) in 2016’s eleven-mission event hosted by the Beijing Institute of Technology.

AKAMAV’s debrief of IMAV 2016 is well-written and insightful. It covers not only the five outdoor and six indoor missions, but also details what it was like to prepare for and compete in such an intensive event. In their words, “If you share even a remote interest in flying robots and don’t mind the occasional spectacular crash, this place was Disney Land on steroids.”

Cheap 360 Degree Camera

October 9, 2016 by Al Williams 11 Comments

How much would you pay for a 360 degree camera? How about $15 if you already have a Raspberry Pi and a Pi camera hanging around? If you don’t, you’ll have to add that minimal cost into the build. [Gigafide] noticed how a spherical mirror, made to see around corners, showed an all-around view if you took a picture of it from below. He snagged a panoramic lens made for an iPhone and stripped it for its optics. Some custom software and a little work resulted in a usable 360 degree camera.

SimpleCV (a light version of OpenCV) provides the algorithms to unwrap the frames and you can take video with the setup (see the video below). Mounting the optics took some 3D printing and the Pi operates as a hot spot to send the video out.
