Time&Space Wiring-Harness Label & Tape Detection Dataset (YOLO format)
Year: 2026
Type: dataset
Abstract: Object-detection dataset of 4,726 images of wiring-harness regions captured on a fixture table during quality-control inspection. Each image is a square region-of-interest (ROI) crop from one of 8 test cases and 2 workspace zones. Images are annotated with axis-aligned bounding boxes for two classes: "label" (harness identification labels) and "tape" (wrapping tape). TWO ARCHIVES, SAME IMAGES- dataset_tns_raw.zip (37 MB) - images without preprocessing. JPEG, as exported from the annotation platform [Roboflow]; the original capture format was not preserved.- dataset_tns.zip (525 MB) - the same 4,726 images after CLAHE (clip limit 2.0, 8x8 tiles, applied to the L channel of LAB), stored as lossless PNG. Both archives have the identical structure, split, file names (apart from the extension) and label files: train/images, train/labels valid/images, valid/labels test/images, test/labels data.yaml Labels are in YOLO format: one line per object, "class x_center y_center width height", normalised to [0, 1]. Class 0 = label, class 1 = tape. An empty label file means the image is a background image. data.yaml is ready for Ultralytics YOLO (path: .). CONTENTS- train: 3,307 images (label 320, tape 2,603, background 384) - 51 capture sessions- valid: 944 images (label 96, tape 784, background 64) - 15 capture sessions- test: 475 images (label 64, tape 364, background 47) - 8 capture sessions- total: 4,726 images (label 480, tape 3,751, background 495) - 74 capture sessionsEvery image contains at most one annotated object. The 495 background images contain no target object and act as hard negatives (other harness elements). SPLIT PROTOCOLThe 70/20/10 split was built by capture session with group key = (Test_Case x Zone x Iteration), so near-duplicate frames of one physical wiring arrangement never appear in different splits (verified: 0 shared sessions between splits, 0 duplicate files). FILE NAMINGTest_Case_{case}_Z{zone}_{frame|E-1}_{iteration}_ROI_{roi} case = 0-7, zone = 1-2, frame = burst frame index or E-1 (an additional underexposed shot), iteration = repetition of the arrangement, roi = ROI crop index.An 8-hex suffix (e.g. __a1b2c3d4) marks files that share a name but differ in content.
