We're building a system that works similarly to sports auto-tracking cameras (e.g. Veo), but with a simpler, classical computer-vision approach — no deep learning or trained models needed. What we need: Camera stitching: Combine footage from two fixed cameras (mounted on one rig, overlapping field of view) into a single panoramic image (~180°), using calibration/homography. The cameras don't move relative to each other, so this should be a one-time calibration applied per frame. Motion-density tracking: From the panoramic feed, detect where players are concentrated (background subtraction / foreground blob density, not per-object classification) and use that to drive an automatic pan/crop — i.e. a virtual camera that follows the action without a human operator. Output: a single, smooth, watchable video stream (no visible seam/ghosting at the stitch line, no jittery panning). What this is NOT: we are not looking for a deep-learning/ball-detection/player-identification system. Classical CV techniques (homography, background subtraction, centroid tracking, Kalman/low-pass smoothing) are the right toolset here — please don't propose a large AI/ML infrastructure buildout. Ideal candidate: Strong hands-on experience with OpenCV (stitching, homography, background subtraction) Has shipped at least one real-time video processing project (not just offline/batch) Comfortable working with two-camera / multi-camera rigs and frame synchronization Bonus: experience with sports or surveillance camera systems

Hi, I am a software engineer with over 16 years of experience, including real-time computer vision, OpenCV, multi-camera video pipelines, calibration, homography, synchronization, and smooth motion tracking. I understand that you need a practical classical-CV solution—not an unnecessary AI/ML buildout. I can develop the complete pipeline from one-time two-camera calibration and panoramic stitching through foreground-density analysis and a stable virtual pan/crop. My focus will be on real-time performance and watchable output, with careful handling of alignment, exposure differences, seam blending, ghosting, synchronization, and low-pass/Kalman smoothing to prevent jitter or abrupt framing changes. I can also help define camera placement and calibration procedures so the system remains reliable outside the initial test setup. Do you already have the target hardware, camera models, resolution/frame rate, and sample synchronized footage? Also, should the output be delivered as a recorded file, RTSP stream, or another live interface? Please contact me to discuss details.

Hi, I am Adeel. This is a clean classical CV problem, and I would treat it exactly that way rather than reaching for deep learning. For the stitch I would compute the homography once during a calibration pass, since the rig is fixed, then warp and blend every frame with a fixed seam mask so there is no per-frame recomputation cost. For the pan I would run background subtraction to get a foreground density map, take its centroid, and drive the virtual camera through a low-pass or Kalman filter so it glides rather than jitters. Are the two cameras genuinely genlocked, or do we need to handle frame-level sync ourselves?

Hi We recently built a classical computer-vision system for dual-camera sports video processing using OpenCV. I used feature matching and homography matrices for one-time static calibration, blending two overlapping feeds into a ~180° panoramic stream. I implemented MOG2 background subtraction to generate high-density foreground masks and tracked action centroids using a Kalman filter to keep virtual pan-and-scan camera movements smooth and jitter-free. My fix eliminated seam artifacts at the overlap line and maintained 60 FPS real-time throughput. Our suggestion would be to build this pipeline using C++ or Python with OpenCV and FFmpeg for multi-camera frame synchronization, homography blending, and real-time virtual camera cropping. We’d structure the motion-density estimation and smoothing as a lightweight processing service to ensure ultra-low latency without complex deep-learning overhead. We are eager to discuss the project further. Reach out to initiate a conversation! Best regards, Quantum Code Solutions

Hello. The hard part of your Sports Camera Motion-Tracking System is achieving seamless real-time panoramic stitching and smooth motion-density tracking without deep learning, relying solely on classical computer vision techniques. I will use your specified stack—OpenCV for homography-based stitching and background subtraction, combined with centroid tracking and Kalman filtering for motion-density detection. My approach: 1. Deliver a calibrated, stable panoramic stitch from your two fixed cameras with no visible seams or ghosting. 2. Implement background subtraction and density-based player concentration detection on the stitched feed. 3. Develop a smooth virtual pan/crop system driven by the detected motion density, ensuring jitter-free output. 4. Provide a single continuous video stream output integrating all components. I have shipped a real-time multi-camera video processing system using OpenCV for a surveillance client, handling frame sync and smooth tracking without ML. Another project involved panoramic stitching for a sports replay system with low-latency output. Please share any sample videos or calibration data to start the first deliverable: a stable stitched panorama. Looking forward to your reply. Best

Hi there! Getting smooth panoramic stitching from two fixed cameras without visible seams, while also driving a jitter-free auto-pan based on player density, is genuinely hard — many implementations show ghosting at the stitch line or a shaky, unwatchable virtual camera. I've worked with OpenCV on real-time video processing, including homography-based stitching, background subtraction for motion/blob detection, and centroid tracking with Kalman/low-pass smoothing for steady camera movement. I'm comfortable with multi-camera setups and frame sync, and I agree classical CV is the right call here over a heavy deep-learning pipeline, it's faster to tune, easier to debug, and needs no training data. I'll start with a one-time calibration for accurate homography between your two feeds, then build the stitching pipeline to blend the seam cleanly. Next, I'll implement background subtraction for player density across the panoramic frame and drive the virtual pan/crop off that with smoothing, so output feels natural, not jittery. I'll test on sample footage early to validate seam quality and pan behavior before scaling up. Check our work https://www.freelancer.com/u/ayesha86664 Do you have sample footage from your rig I could test calibration and stitching against? Let me know if you're interested and we can discuss it. Best Regards Ayesha

Hi there, The main challenge is getting two fixed camera feeds stitched cleanly and then turning that panoramic view into a smooth virtual camera that follows the action. Your classical CV approach makes sense here, and there’s no need to add unnecessary deep learning. We’ll use OpenCV for camera calibration, homography and stitching, with the fixed rig allowing the calibration to be reused on every frame. For action tracking, we’ll use background subtraction and foreground density, then apply smoothing to control the virtual pan and crop without jitter. We’ll also handle frame synchronization and optimise the processing so the final output stays smooth without visible seams or ghosting. What resolution and FPS are the cameras using? Do you already have sample footage from both cameras? Where will the processing run, PC or edge device? Let’s have a quick chat and review the camera setup and footage to define the right OpenCV pipeline. Budget and Timeline are placeholders. Regards, Royal Designs (FK)

You need a system that stitches two fixed cameras into a 180° panorama and then tracks player density to automatically pan and crop the view. I will start by calibrating the cameras for stitching. The camera stitching will use OpenCV for homography estimation, taking pairs of corresponding points from overlapping frames to create the transformation matrix, so each output frame will be a stitched panorama. For motion-density tracking, I will use background subtraction to identify moving objects, then aggregate the resulting foreground pixels into density maps, so the highest density areas will dictate the pan and crop position. I will use adaptive thresholding on the density maps to find the center of action. I would build the stitching module first, so that the motion tracking has a stable, combined input to work with. What resolution are the source camera feeds? I am a Preferred Freelancer with a 5.0 rating over 10 reviews, delivered on time and on budget each time. Send me the resolution of the source camera feeds and I will send back a breakdown of the timeline for each module.

Hi, This project is a strong match for my **16 years of R&D experience in computer vision, embedded systems and real-time video processing**. I have completed **AI Dashcam, ANPR, YOLO and machine-vision projects** involving real-world camera/video processing. I understand that you specifically need **classical OpenCV**, not deep learning. I can develop the complete pipeline: * Two-camera calibration and synchronization * Fixed homography-based panoramic stitching * Seam/blending optimization to minimize ghosting * Background subtraction and foreground-motion density * Motion centroid/region estimation * Virtual camera pan/crop based on player concentration * Low-pass/Kalman smoothing for stable, natural movement * Real-time optimized video output OpenCV directly supports homography-based stitching and perspective warping, making this approach well suited to your fixed-camera rig. ([GitHub][1]) My previous **AI Dashcam, ANPR and machine-vision work** gives me practical experience with camera pipelines, OpenCV and real-time video analytics. I will keep the implementation lightweight and deterministic without unnecessary AI/ML infrastructure. I can deliver the calibration tool, complete OpenCV pipeline, configurable parameters, source code and testing procedure.
