Yesterday, we built opencv-3.3.1 and contrib for Jetson TX2. After opencv-3.3, opencv contains yolo deep neural network. So, we make a simple ROS node for object detection by using tiny yolo and try it!! The code is here. This node can run only 2Hz. This is 5 times as slow as using using darknet in […]
ros-kinetic-opencv3 package is very useful for ROS users, but this package is not supported cuda. So, we built ros-kinetic-opencv3 packages with cuda modules in Jetson TX2. Compiled binary is here. Usage is below. 1.install dependencies 2.remove ros-kinetic-opencv3 3.install dpkg We built this .deb file in this way.(<a href=”https://qiita.com/kendemu/items/a805b0b9828b6f6031db”>reference</a>) 1.get ros-kinetic-opencv3 source from apt-get 2.remove source files […]
In order to use Jetson TX2 and Deep Learning in this competition, I tried to run darknet in Jetson TX2 and tested Jetson TX2 throughput. In this post, I used Tiny-Yolo deep neural network in Jetson TX2. This is the result of object recognition. Tiny yolo structure is here. dog.jpg eagle.jpg giraffe.jpg person.jpg scream.jpg Prediction […]
We use tensorflow in order to use deep learning algorithms such as Faster-RCNN, Yolo, VoxelChain. Compiled .whl file is here. If you want to install tensorflow into Jetson TX2, you should follow these instructions. 1. download jetson_tensorflow.zip 2. unzip jetson_tensorflow.zip 3. cd jetson_tensorflow 4. sh install.sh We checked this .whl file by using this python […]
Dec.2017 12th-13th, we conduct a poster presentation in GTC JAPAN 2017. GTC Japan (gpu technology conference) is an international conference which held by Nvidia. In this presentation, we talk about our project and our ship structures, algorithms, hardware equipments. We are planning to extend the drive time by using Jetson TX2 and Li-ion battery. Our […]
We build object recognition system using point cloud data. This node are composed of ros_ship_recognition package. The object_recognition_node detect objects by using SHOT features. We conducted a presentation about this node in ROS Japan user group meeting in Kansai. 3D Object Detection using PCL (Point Cloud Library) from masaya kataoka Demonstration movie is here.
We are building gazebo/ROS simulation package for WAM-V. Our simulator has a such characteristics. 1. buoyancy simulation We calculate buoyancy from archimedes’ principle and simulate it! 2. driving force simulation Ship’s driving force are calculated from it’s speed and propeller rotational speed. We develop driving force controller and control ship’s driving force. 3. Visualization We made […]
