"Great work.  I am working towards this as well using ROS and adding a depth camera.  Many thanks for sharing."

Convolutional Neural Network (2) for advoiding obstacles

By changing the CNN of my previous post CNN (1) into a multi-classification CNN (fly, go left, go right, stop) and adding an appropriate multi-thread python dronekit script, my drone bypasses most of the obstacles encountered at our "Model Club de la Côte de Beauté - MCCB". The YouTube video demonstrates the obstacle avoidance of my drone in loiter…See More

"During training of my CNN I focused on avoiding persons. Static tests at the MCCB club (Charente Maritime – France) showed that my CNN-drone decided to stop at 5m. Dynamic tests in Loiter mode flying at 1.7-2.3 m/sec confirmed that my drone…"

"Bonjour André, That is quite good !!  It makes the concept a real time avoidance system, even without the Movidius. The gain with Movidius  (5X) is less than what Intel's Marketing  is pretending with... ''one…"

"@ Mike Isted: Thx @ Patrick  Poirier I optimized my architecture and compared the average processing time Tav of one video frame on RPI3 with and without Intel's Movidius. The results obtained are: Tav (without Movidius) = 0.17 sec, Tav…"

"Hi Andre, Excellent work, well done. I am slowly heading in a similar direction and am migrating from RPi/Picam to Jetson TX2/Realsense.  I am also moving to Mavros. As with you, I have learnt much from Adrian Rosebrock and his courses. Happy…"

"@Patrick Poirier Bonjour Patrick I still have to perform additional testing to get all the characteristics. This will be done In France during Eastern holidays. On my RPi3 I measure a cycle time of 0.2 sec (5Hz)."

"Bonjour André, Looking at the video , I see you are using dronet  https://github.com/uzh-rpg/rpg_public_dronet for training on a fly/stop scenario which is the best strategy for testing. The speed seems pretty good on the PC (I would say…"

Profile Information

About Me:
Retired prof. in (micro)electronics
Please tell us a bit about your UAV interest
Like building, designing electronic sensor modules. Today's project is designing and building a quadcopter.
Hometown:
Gent, Belgium

1st quadcopter

I bought an Frsky DF 2.4Ghz Combo Pack and dismantled the transmitter package and built my own transmitter as shown.

Apart from the DFT 8-channel  transmitter,  the RC Tx/Rx unit has an own built board with 2 psoc1 mcu’s from Cypress for generating the ppm signal, reading the sticks position and  BT pc communication.

Milling of pcb

A python program controls the settings of the RC Tx/Rx unit and displays the telemetry data

The different parts of the quadcopter are milled in plastic and aluminum. The flightcontroller is the wellknown KK2.0.

Testflights were successful and I gained a lot of experience from this 1st quadcopter.

obstacle avoidance using a convolution neural network

Posted on March 12, 2018 at 5:30am 16 Comments

Recently I started working on convolutional neural networks (cnn) for obstacle avoidance. With the help of "DroNet" from ETH Zurich and the "Deep Learning for Computer Vision" book from Adrian Rosebrock, I managed to build my first cnn algorithm for obstacle avoidance. The cnn module is written in python, using a keras…

My XJ470 rebuilt

best viewed with 720p HD settings

This winter I rebuilt my XJ470: added a PiZero with a Picam. This PiZero functions as a companion computer with a python dronekit and a WiFi access point enabling a mavlinkbridge. Hence an android tablet, running Tower, can be connected to this WiFi access point for…

testflight xj470

Posted on September 12, 2015 at 2:42am 2 Comments

For bench marking my own developed flight controller, I built a Quanum XJ470 drone with a DroPix (Arducopter/PixHawk) flight controller. Some additional features: esc AFRO 30A; motors: SunnySky 980 KV; props 10 x 4.5. My first testflight shows that the drone with the DroPix flies great.
