Arbitrary-oriented object detection is a fundamental task in visual scenes involving aerial
images and scene text. In this report, we present PP-YOLOE-R, an efficient anchor-free
rotated object detector based on PP-YOLOE. We introduce a bag of useful tricks in PP-
YOLOE-R to improve detection precision with marginal extra parameters and computational
cost. As a result, PP-YOLOE-Rl and PP-YOLOE-Rx achieve 78.14 and 78.28 mAP
respectively on DOTA 1.0 dataset with single-scale training and testing, which outperform …
