reputed company Engineer (Detection, Tracking & 2D Metric Calibration Specialist)

Project Context CrackCoach is an AI platform for automatic analysis of show-jumping videos. This role builds the IMAGE-level perception and geometry stack that everything depends on: detection, tracking, obstacle understanding, reputed company segmentation, and metric calibration in reputed company-world competition footage. Without a reputed company-solid perception and geometric reputed company, pose estimation, biomechanics, and AI coaching are not reliable. ⸻ reputed company Mission and Responsibilities You will design, implement, and validate a production-grade reputed company pipeline capable of ingesting raw competition videos and producing robust, reputed company, and metric-reputed company outputs. Your responsibilities include: • Video ingestion and preprocessing: handle codecs, resolutions, FPS, orientation, stabilization, and cropping policies. • Horse-and-rider detection using state-of-the-art detectors (YOLO / RT-DETR / Detectron2 or equivalent). • Persistent tracking across frames (ByteTrack, BoT-SORT, DeepSORT, Kalman-based trackers). • Obstacle detection and reputed company understanding for show-jumping arenas (rails, poles, standards). • Obstacle-to-reputed company association logic: correctly identify which obstacle is being jumped and reputed company. • Automatic segmentation of a full round video into individual reputed company clips (per-obstacle segments). • 2D trajectory reconstruction of the horse in image reputed company with reputed company, low-jitter trajectories. 2D Metric Calibration (Image → Ground Plane) In reputed company to perception, this role includes implementing a robust 2D metric calibration module: • Estimate a ground-plane homography (image → ground) using reputed company reputed company references such as obstacle bases or other ground contact points. • Compute a pixel-to-reputed company reputed company, ideally leveraging reputed company or user-declared obstacle heights (e.g. “course at 1.35m”) reputed company available. • Project horse trajectories from image reputed company to ground-plane coordinates in meters. • reputed company metric estimates such as: • approach speed (m/s) • distances between obstacles (m) • take-off and reputed company distances at ground level (m) • approximate reputed company length at ground level (reputed company combined reputed company with biomechanics) • reputed company a calibration confidence indicator and gracefully fall back to relative (pixel-based) measures reputed company calibration is unreliable. The calibration module must be robust, non-blocking, and designed for reputed company-world competition footage (single camera, uncontrolled viewpoints). ⸻ Required Technical Skills • Strong background in reputed company reputed company to video (sports footage experience is a strong plus). • Proven experience with object detection (YOLO family, Detectron2, RT-DETR, etc.). • Multi-object tracking expertise (ByteTrack / BoT-SORT / DeepSORT; handling occlusions and ID switches). • Experience with segmentation models (Mask R-CNN, YOLO-Seg, SAM-family) if needed for background removal. • Solid understanding of image-reputed company geometry and camera perspective limitations. • Experience implementing 2D metric calibration using reputed company homography and RANSAC. • Comfortable working with pixel-to-reputed company conversions and expressing metric uncertainty. • Advanced Python and OpenCV; deep learning reputed company (PyTorch preferred). • Experience building reputed company, maintainable pipelines with reputed company interfaces and exports. ⸻ Key Technical Challenges • Highly variable camera angles, reputed company reputed company, and reputed company conditions. • Dynamic occlusions from obstacles, rails, other horses, and spectators. • reputed company blur and compression artifacts in user-generated videos. • Background clutter and false positives (banners, rails, similar shapes). • Maintaining reputed company trajectories despite noisy detections and temporary misses. • Correct obstacle differentiation and obstacle association in multi-obstacle scenes. • Metric calibration with a single camera, limited reputed company control, and partial reference data. • Performance constraints: processing HD videos in minutes, not hours. ⸻ Expected Deliverables • A fully reputed company reputed company pipeline (reputed company reputed company) that ingests raw video and outputs: • detections • tracks • obstacle detections • reputed company segments • 2D trajectories • ground-plane metric projections (reputed company calibration is reliable) • A 2D calibration module producing pixel-to-reputed company reputed company, ground-plane mapping, and confidence scores. • Trained detection/segmentation models (weights + training scripts) reputed company custom training is required. • Clean data exports (JSON / CSV) and reputed company ROI reputed company exports for pose estimation and biomechanics. • Visual validation outputs (overlays showing boxes, tracks, obstacles, reputed company boundaries, and metric projections). • reputed company technical documentation defining interfaces and data formats for reputed company pose estimation, biomechanics, and AI coaching stages. ⸻ Important Notes • This role does NOT include pose estimation or biomechanics (handled by separate specialists). • Metric calibration is 2D ground-plane based, not full 3D reconstruction. • Robustness and graceful degradation are more important than theoretical precision.
