Panoramic photographing method for unmanned aerial vehicle and unmanned aerial vehicle using the same

An unmanned aerial vehicle (UAV), comprising:

• a flying mechanism;
• a wireless transceiver;
• a digital camera;
• an inertia measurement unit for detecting a flying altitude and a flying angle, and outputting a feedback signal;
• and
• a control unit coupled to the flying mechanism, the wireless transceiver, the digital camera and the inertia measurement unit, wherein the control unit controls the flying mechanism to control the flying altitude and the flying angle according to a signal received by the wireless transceiver, and determines the flying altitude and the flying angle according to the feedback signal of the inertia measurement unit, wherein:
• when the wireless transceiver receives a panoramic photographing instruction, the control unit controls the digital camera to perform photographing, and records the flying altitude and the flying angle of the UAV of each of photographed pictures;
• and
• when an image stitching process is performed, overlapped regions of the two photographed pictures photographed in order is determined according to the flying altitude and the flying angle, and a feature operation region is obtained by way of division, and then a feature operation is performed in the feature operation region of the two photographed pictures to determine an image stitching location, and thus generate a panoramic picture.
