Collect and label road images
Capture diverse daytime and night-time frames and label lane lines as segmentation masks or polylines; include occlusions and multiple road types.
Detect lane markings. Assess localisation accuracy.
Lane detection locates road-lane markings in camera frames to support vehicle path planning and driver assistance. Typical outputs are pixel-wise segmentations or line detections; failure modes include occlusion, worn paint, shadows and unusual road geometry. Robust evaluation must combine localisation metrics with operational checks for false negatives and latency.

Lane detection locates road-lane markings in camera frames to support vehicle path planning and driver assistance. Typical outputs are pixel-wise segmentations or line detections; failure modes include occlusion, worn paint, shadows and unusual road geometry. Robust evaluation must combine localisation metrics with operational checks for false negatives and latency.
A proposed application for driver-assistance: highlight detected lane lines on a vehicle HUD so a human driver can confirm or ignore suggestions. Because this affects driving decisions, a human must remain in control and the prototype should not be used for real vehicle control without extensive validation and safety certification.
Capture diverse daytime and night-time frames and label lane lines as segmentation masks or polylines; include occlusions and multiple road types.
Train a compact segmentation or lane-line detector (for example UNet or a lightweight detector) on the labelled images with augmentations for brightness and blur.
Report IoU or endpoint error for lanes, measure false-negative rate for visible lanes, and benchmark inference FPS on target hardware.
Export an inference pipeline with preprocessing, confidence thresholds, runtime checks and monitoring for input drift and degraded accuracy.
The supplied starter loads the sklearn digits dataset, splits it, fits a RandomForestClassifier to digit feature vectors, prints a classification report and shows a confusion matrix. It does not load road images, nor implement segmentation or lane-line detection.
digits = load_digits()
X_train, X_test, y_train, y_test = train_test_split(
digits.data,
digits.target,
test_size=0.25,
random_state=42,
stratify=digits.target,
)
model = RandomForestClassifier(n_estimators=300, random_state=42)
model.fit(X_train, y_train)The starter trains a classifier on handwritten-digit vectors (sklearn digits). That data and model type are unrelated to lane detection: there is no image-frame preprocessing for road scenes, no segmentation or line fitting, and no relevant spatial metrics such as IoU or endpoint error. Results from the digits task do not validate lane-detection performance.
A proposed extension is to train a semantic-segmentation or specialised lane-line detector on labelled driving datasets (for example TuSimple or CULane), add augmentation for weather and occlusion, and produce a visual overlay plus confidence scores for human review.
This is a potential application pathway, not a delivered product. The supplied starter does not implement this service or validate it with real users.
