Computer 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. ⸻ Core Mission and Responsibilities You will design, implement, and validate a production-grade computer reputed company pipeline capable of ingesting raw competition videos and producing robust, reputed company, and metric-aware 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 computer 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 computer 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.
