Can gesture controlled drones really solve pilot problems in UAV??
First of all thanks for reading my blog! now let’s come to the point that
Drones are widely being used in videography and photography. Now-a-days you can see many drones are flying in the sky but everytime there’s must be an smart pilot with it to control it from ground. But a new gesture technology has involved to solve this problem. This incredible technology introduced by a group of BITs Dubai’s teaching assistants. In this experiment they used leap motion controller to recognise human body gestures. There are previous implementations of gesture control of an AR Drone on platforms like cyclone.js and nodecopter using the Leap. they used ROS(robust operating system)
What is leap motion controller?
The Leap Motion Controller as shown in Fig.1 is a gesture recognition device which uses advanced algorithms for such operations. From a hardware perspective, the Leap Motion Controller is an eight by three centimeter unit, which comprises two stereocameras and three infrared LEDs. The two stereo cameras as well as the three infrared LEDs perform the function of tracking the infrared light having a wavelength of about 850 nanometers, which is outside the visible light spectrum.
The Leap Motion Controller uses its two monochromatic infrared (IR) cameras and three infrared LEDs to track any hand motion up to a distance of about 1 meter or about 3 feet directly above it. Thereby, it forms a hemispherical area above itself whose radius is about 1 meter and recognizes any hand motion occurring in that plot of volume.
The hand gestures are captured by the Leap Motion Controller, which is then relayed onto the ground station. The Leap SDK on the ground station translates the gesture and then the talker or publisher method takes over. The publisher method publishes the translated hand gesture as a message on the AR Drone as ROS topic for communication.
This gesture based technology is really revolutionary and yes it will solve pilot problems. But there are still some cons in this technology like controlling range and accuracy to do task. But in future we will be using this technology without any doubt.
