Based on contributions by Luckyhipster10, Mathijs. If you don’t have enough hand-annotated images for a good oriented bounding box (OBB) model, you can generate extra training images by applying random transformations (…

Based on contributions by elenavoicila, Mathijs. If you only care about objects in part of the camera frame (e.g. a conveyor lane or a fixed pickup area), restricting detection to that region of interest (ROI) cuts down…

Based on contributions by sarahstam, 20129556. A regular YOLO bounding box is always axis-aligned, so it can’t tell you how an object is rotated. An oriented bounding box (OBB) model fits a rotated rectangle to each obj…

Based on contributions by elenavoicila, aashish. Once you’ve trained a YOLO model (see How to train a YOLO object detection model with Roboflow and Ultralytics), use this to run it live on a webcam feed, draw the detect…

Based on contributions by Mark.jensen, Rafika. Before you can train a YOLO model you need a labelled image dataset: a set of images with a box (or polygon) drawn around every object you want to detect. Roboflow is a fre…
