Abstract

At present, there are only few instruments that are available to be used for aerial imaging, data gathering and remote sensing. Most of these devices are not affordable and cannot be easily controlled by common people. This study aims to implement a user-friendly and relatively cheap instrument that is capable of recording aerial videos and images. A quadcopter, a type of Unmanned Aerial Vehicle (UAV), was designed and built to take aerial pictures and videos for land area estimation. Three different images were obtained to compute for the equation of the pixel scaling of the camera with respect to different altitudes. Different image processing techniques such as image stitching, image threshold, image binarization and boundary-detection, were used to compute the perimeter and area of the subject of the image. Greens Theorem and sum () function were used to compute the area of the region of interest. It was found out that there exists an equation of the pixel ratio of the camera and the altitude. A land area plot was estimated and showed an accuracy of 78.09% for the sum () function and 76.90% for the Green?s Theorem. The estimated perimeter showed an accuracy of 91.31%. The green patches found in the stitched image was also estimated. The area estimation showed a value of 2.83 square meters while the perimeter estimation showed a value of 76.47 meters.
