Safety helmet (hardhat) wearing detect dataset(安全帽佩戴检测数据集, SHWD).
SHWD provide the dataset used for both safety helmet wearing and human head detection. It includes 7581 images with 9044 human safety helmet wearing objects(positive) and 111514 normal head objects(not wearing or negative). The positive objects got from goolge or baidu, and we manually labeld with LabelImg. Some of negative objects got from SCUT-HEAD. We fixed some bugs for original SCUT-HEAD and make the data can be directly loaded as normal Pascal VOC format.
The distribution of data is extremely inhomogeneous, which can be soloved by undersampling or oversampling.
