【Abstract】 With the development of relevant technologies,unmanned aerial vehicle and non- metric camera have been used in aerophotography more and more. It has unique advantages especially under some special situations such as emergency relief. This paper takes an emergency relief project of orthophoto production as an example,introduces the data post processing methods of unmanned aerial vehicle aerophotography based on PixelGrid software,analyzes the accuracy of productions and makes the efficiency statistics.The results show that this method is feasible with high efficiency.更多还原
