Visualization of object detection annotation file based on relative value description in Python 22

Although there are labelme、labelimg Etc. marking sharp weapon , But on some public datasets , Instead of using these public formats . It is a kind of standard information based on aspect ratio , Such as Satellite application competition —— Data set of intelligent detection of marine ships , Use relative values to describe dimension targets , The details are as follows: 1 Shown ：

For this txt The annotation information described by the format , Unable to visualize quickly , So develop python Scripts enable rapid visualization of such data .

1、 Read a single image to visualize and save

label_list=[]
with open(label_path,"r") as f:
label_list = f.readlines()
result=[]
