aerial_cloud_detection's Introduction

aerial_cloud_detection

利用Mask_Rcnn與HSV 做簡易pixel-wise 的雲層檢測,並簡易推斷厚雲與薄雲的面積。

##過程與結果

  1. 先利用現有的資料(約略200張)做labelme的Mask標定,再轉至Mask_rcnn可訓練的資料做訓練,原始資料如下: image

  2. 獲得Mask Rcnn初步雲朵位置,因這次的訓練資料較少,所以訓練10次,每次100筆資料訓練,loss如下圖: image image 這裡的結果沒有很精準是沒問題的,目的只是框選出大部分雲朵的pixel

  3. 統計Mask所選取的Pixel HSV中的V值,透過這統計來分析該張相片的厚、薄雲的V閥值 image

  4. 最後統計厚雲(紅色)與薄雲(綠色)之pixel統計值,並計算其在照片中所占面積比例。
