Abstract: A system for controlling an unmanned aerial vehicle (UAV) includes a processor and a storage medium storing instructions that, when executed by the processor, cause the processor to receive image data from a camera coupled to the UAV that is associated with a first view of the camera, send the image data in real time to a client device, and receive control data from the client device. The control data is associated one or more reference coordinates corresponding to a gesture-based input indicating a change from the first view to a second view of the camera. The gesture-based input is associated with at least one region of the image data. The instructions further cause the processor to control the UAV to change at least one of a position or an attitude of the UAV based on the control data.

Abstract: A system for operating a mobile platform using distance and speed information and methods for making and using same. The system includes a time-of-flight sensor and an ultrasound sensor for measuring a distance between the mobile platform and an obstacle and a processor for integrating the sensed measurements and controlling the mobile platform. The distance measured by the time-of-flight sensor can be determined via a phase shift method. The time-of-flight sensor can also be used to measure a speed of the mobile platform by imaging a reference point at different times and using stereopsis to ascertain the displacement. Distances and speeds measured using the time-of-flight and ultrasound sensors can be integrated to improve measurement accuracy. The systems and methods are suitable for use in controlling any type of mobile platform, including unmanned aerial vehicles and advantageously can be applied for avoiding collisions between the mobile platform and the obstacle.
