This study presents a deep learning-based recognition system that combines strawberry object detection and pose estimation to deliver real-time recognition information for robotic strawberry harvesting. The system is implemented on a single embedded platform, integrating a Jetson-based computing device with an RGB-D camera. This setup allows for real-time image acquisition, object detection, and keypoint detection in greenhouse environments. Training data were collected from a greenhouse using the RGB-D camera, with three keypoints (fruit center, calyx, and pedicel) annotated in both bounding box and keypoint formats across 557 images. A top-down pose estimation approach utilizing the YOLOv9-pose model was employed. Experimental results demonstrated an object detection performance of 0.94 mAP@0.5, with average keypoint localization errors of 2.54 pixels along the x-axis and 2.88 pixels along the y-axis. When converted to real-world coordinates using depth information, the average spatial errors were 8.57 mm and 2.45 mm. The system achieved an average inference speed of 16.9 fps in the vertical direction, even under varying object density conditions. These results suggest that the proposed system can significantly enhance recognition technologies for automated strawberry harvesting.
