Jump to: navigation, search ROS_OpenTLD is a ROS version of the OpenTLD tracker. OpenTLD is a C++ implementation of TLD Predator (Tracking. Learning and Detection) implemented by the AIT (Austrian Institute of Technology), that was originally published in Matlab by Zdenek Kalal. OpenTLD is used for tracking objects in video streams. The ROS implementation consists of two nodes: the tracker node which use the opentld library and an interface node that allow you to select a bounding box, start stop the tracking, start and stop the learning, import or export a model, clear the background and change the tracker's method. In the two launch files, you can configure the input video stream. In the tracker launch file, you can configure the bounding box source, the default bounding box if there is one, the model that you may want to load and its path, the automatic face detection by the OpenCV cascade classifier and some others parameters.

Like OpenTLD, ROS_OpenTLD is published under the terms of the GNU General Public License. You can get the source code on GitHub : There are many possible applications in robotic. For example, ROS_OpenTLD is already used for tracking cars from a ROS version of the Parrot AR Drone. On our part, we used the algorithm in the purpose of tracking a target (a head or a body) and following this target with a robotic mobile platform.

Developers wishing to develop their own applications for the AR.Drone are forced to familiarize themselves, not only with the architecture of the drone, but also with several third-party development tools. This makes it very difficult, and almost impossible, for persons without the necessary technical knowledge, (eg. control engineers, researchers, younger students, etc.) to try out their own applications on the AR.

Today, we are willing to make a platform that allows nearly everybody to make easily their own AR.We want this tool to be graphical, and integrated to Matlab/Simulink, as this is a very well-known tool. To allow the user to describe his application in a graphical way, on Simulink, we need to make a Toolbox. parrot ar drone c#That is to say, we need to develop blocks, which can be bound to the others. parrot ar drone dove comprareThus, we are going to develop Simulink blocks for:parrot ar drone race donut the sensors (Inertial Measurement Unit, video stream, etc)black ops 2 dragonfire drone review

the actuators (engines, LEDs, etc) Tu put in a nutshell, to get data from the drone sensors or to send order to the actuators, the user will only have to drag and drop the proper block on his Simulink description.ar drone power edition recensione Once the application designed, there are several steps to follow in order to make an application that can run on the drone :parrot ar drone spektrum dx6i transforming the Simulink graphical description to source code. This step is called the "code generation" adaptating the source code to make the application speaking to the Drone sensors and actuators compiling the source code to make an executable file upload the application on the drone. Our main goal is then to include the whole development process into the same platform, to make the development easier and nicer.

All those steps will be run by clicking on a magic button, displayed on the interface. The following drawing shows the action of the magic button : If we have time, we will try to set up a real time kernel on the AR Drone and compare the performance with the old one. The code will also need to be adapted, by wrapping it into real-time tasks. Elodie Devineau - Product Owner Man is a drone to drone...An implementation of the networking protocols used by the Parrot AR Drone 2.0. It appears that 1.0 drones are also compatible. Install via Github to get the latest version: Or, if you're fine with missing some cutting edge stuff, go for npm: The AR Drone is an affordable, yet surprisingly capable quadcopter. itself runs a proprietary firmware that can be controlled via WiFi using the official (available for iOS and Android). Unlike the firmware, the client protocol is open, and Parrot publishes an SDK (signup required to download) including a good amount of documentation and C

Their target audience seems to be mobile developers who can use this SDK to create games and other apps for people to have more fun with their drones. However, the protocol can also be used to receive video and sensor data, enabling developers to write autonomous programs for the upcoming robot revolution. This module is still under heavy development, so please don't be suprised if you find some functionality missing or undocumented. However, the documented parts are tested and should work well for most parts. This module exposes a high level Client API that tries to support all drone features, while making them easy to use. The best way to get started is to create a repl.js file like this: Using this REPL, you should be able to have some fun: Now you could write an autonomous program that does the same: Ok, but what if you want to make your drone to interact with something? you could start by looking at the sensor data: Not all of this is handled by the Client library yet, but you should at the

very least be able to receive droneState and demo data. A good initial challenge might be to try flying to a certain altitude based on the navdata.demo.altitudeMeters property. Once you have manged this, you may want to try looking at the camera image. is a simple way to get this as PngBuffers (requires a recent ffmpeg version to be found in your $PATH): Your first challenge might be to expose these png images as a node http webOnce you have done that, you should try feeding them into the Returns a new Client object. Launches an interactive interface with all client methods available in theAdditionally client resolves to the client instance itself. Returns a PngEncoder object that emits individual png image buffers as 'data'Multiple calls to this method returns the same object. (e.g. reconnect on error) is managed by the client. Returns a TcpVideoStream object that emits raw tcp packets as 'data' Sets the internal fly state to true, callback is invoked after the drone

reports that it is hovering. Sets the internal fly state to false, callback is invoked after the drone reports it has landed. Makes the drone gain or reduce altitude. speed can be a value from 0 to 1. Causes the drone to spin. Controls the pitch, which a horizontal movement using the camera as a reference point. Controls the roll, which is a horizontal movement using the camera Sets all drone movement commands to 0, making it effectively hover in place. Asks the drone to calibrate a device. supports only one device that can be calibrated: the magnetometer, which is device number 0. The magnetometer can only be calibrated while the drone is flying, and the calibration routine causes the drone to yaw in place a full 360 Sends a config command to the drone. You will need to download the drone SDK to find a full list of commands in the ARDrone_Developer_Guide.pdf. For example, this command can be used to instruct the drone to send all navdata.

callback is invoked after the drone acknowledges the config request or if a timeout occurs. Alternatively, you can pass an options object containing the following: Performs a pre-programmed flight sequence for a given duration (in ms). animation can be one of the following: Please note that the drone will need a good amount of altitude and headroom to perform a flip. Performs a pre-programmed led sequence at given hz frequency and durationanimation can be one of the following: Causes the emergency REF bit to be set to 1 untilThis recovers a drone that has flipped over and is showing red lights to be flyable again and show greenIt is also done implicitly when creating a new high level client. A client will emit landed, hovering, flying, landing, batteryChange, and altitudeChange events as long as demo navdata is enabled. To enable demo navdata use This is a low level API. If you prefer something simpler, check out the Client

The drone is controlled by sending UDP packets on port 5556. does not guarantee message ordering or delivery, clients must repeatedly send their instructions and include an incrementing sequence number with each For example, the command used for takeoff/landing (REF), with a sequence number of 1, and a parameter of 512 (takeoff) looks like this: To ease the creation and sending of these packets, this module exposes an UdpControl class handling this task. For example, the following program will cause your drone to takeoff and hover in place. Now that you are airborne, you can fly around by passing an argument to theA full list of all pcmd() options can be found in the API docs With what you have learned so far, you could create a simple program Creates a new UdpControl instance where options can include: Enqueues a raw AT* command. This is useful if you want full control. For example, a takeoff instructions be send like this:
