第python之json文件轉xml文件案例講解這是yolov4模型跑出來的檢測結果result.json

下面是截取的一張圖的檢測結果

"frame_id":1,#圖片的序號

"filename":"/media/wuzhou/Gap/rgb-piglet/test/00000000.jpg",#圖片的路徑

"objects":[#該圖中所有的目標：目標類別、目標名稱、歸一化的框的坐標（xywh格式）、置信度

代碼需要指定圖片的路徑，例如file_dir="H:/rgb-piglet/five/test"

注意：result.json文件要跟圖片放一起

代碼生成的xml與圖片在同一個路徑下

importjson

importtime

importos

fromPILimportImage

importcv2
