無人機航拍圖像銳度評價方法
發(fā)布時間：2019-01-05 02:18
【摘要】：無人機航拍的圖像會受到橫風干擾而產生模糊,因此亟需一種銳度評價方法,能夠在短時間內從大量圖像中有效地甄別出存在問題的部分。本文介紹了一種基邊緣檢測和直方圖信息分析的銳度評價方法,通過銳度函數的構建和修正對照片進行批量檢驗,不僅使評價結果客觀準確,且運算量小適合推廣。該方法能夠幫助外業(yè)人員篩選存在模糊問題的照片,對提高無人機航拍數據采集工作的質量和效率有較大的幫助。
[Abstract]:The images of UAV aerial photography will be blurred by crosswind disturbance, so it is urgent to use an acuity evaluation method to effectively identify the defective parts from a large number of images in a short period of time. In this paper, a method of acuity evaluation for base edge detection and histogram information analysis is introduced. By constructing and modifying the sharpness function, a batch inspection of photographs is carried out, which not only makes the evaluation results objective and accurate, but also has a small amount of computation suitable for popularization. This method can help field workers to screen photos with fuzzy problems, and improve the quality and efficiency of aerial photography data acquisition of UAV.
