测试时是否翻转和旋转 #37

您好，这是我测试时的pipeline pipeline=[ dict(type='LoadImageFromFile'), dict( type='MultiScaleFlipRotateAug', img_scale=[(1024, 1024)], h_flip=False, v_flip=False, rotate=False, transforms=[ dict(type='Resize', keep_ratio=True), dict(type='OBBRandomFlip'), dict( type='Normalize', mean=[123.675, 116.28, 103.53], std=[58.395, 57.12, 57.375], to_rgb=True), dict(type='RandomOBBRotate', rotate_after_flip=True), dict(type='Pad', size_divisor=32), dict(type='ImageToTensor', keys=['img']), dict(type='OBBCollect', keys=['img']) ] 其中h_flip、v_flip、rotate都是false，但是transforms中又有OBBRandomFlip和RandomOBBRotate。请问到底有没有翻转和旋转？希望您能抽空解答，十分感谢！

h_flip, vflip, rotate是false是不会进行翻转旋转测试的，其中有OBBRandomFlip与RandomOBBRotate是他们要生成一些数据比如生成results['angle'] = 0等

好的，谢谢。请问此代码有没有实现测试时翻转旋转操作呢？

jbwang1997 commented 2 years ago

单阶段网络不支持，双阶段网络是可以的，但是测试结果好像不如不加，翻转与旋转使产生的假正例数量上升，可以尝试一下。
