Hi, ⭐15+ Yrs Sr Developer here⭐ I have experience with real-time tracking systems, AR workflows, sensor-based positioning, and performance-focused mobile development using Kotlin and modern Android frameworks. Your project requires much more than standard navigation, and I understand the challenges around indoor localization, sensor fusion, drift correction, CameraX pipelines, and AR overlay rendering. I can help structure the app with a modular architecture covering landmark detection, graph-based routing, dead reckoning, relocalization logic, and ARCore navigation flows. I’m also comfortable working with OpenCV, SQLite, coordinate transformations, and optimization for continuous real-time tracking on Android devices. My focus would be building a stable, scalable foundation first so future ML models, SLAM improvements, and advanced localization features can be added cleanly over time. If you think I am a good fit, feel free to ping me anytime. — GAZMIR

Hi there I can help with this and I can start right away. I work with Kotlin ARCore and Computer Vision and I have 6 years experience building real time mobile systems where camera processing tracking and sensor data all need to stay synchronized instead of fighting each other every few seconds. For this project I would structure the app with a modular Android architecture using CameraX for live capture ARCore for spatial alignment OpenCV for landmark processing and sensor fusion layers for dead reckoning drift correction and continuous indoor positioning while keeping routing and localization separated into scalable services. I would also focus heavily on performance and recovery handling because indoor AR navigation gets messy very quickly once tracking confidence drops so relocalization logic confidence scoring and corridor constraints need to work smoothly in real time instead of just looking good in demos. Looking forward to building something genuinely advanced with you because this is much more interesting than another delivery app with floating buttons everywhere.

Hi, I can build your Android AR indoor navigation app with a production-ready, modular Kotlin architecture. I’ll use Kotlin, CameraX, ARCore, OpenCV, TensorFlow Lite/ONNX, SQLite, and sensor APIs for real-time camera processing, AR overlays, local matching, and offline navigation state. For localization, I’ll design landmark/logo detection, embedding similarity scoring, confidence validation, image-coordinate extraction, and graph-constrained PnP pose estimation. For navigation, I’ll implement A* routing, waypoint generation, corridor constraints, rerouting, drift correction, and shared session state. For tracking, I’ll fuse accelerometer, gyroscope, compass, and step detector data using dead reckoning with relocalization triggers to reduce indoor drift. For AR, I’ll build coordinate transforms, projection logic, arrows, turn indicators, and screen-space overlays optimized for stable frame performance. I have worked on Android camera-based CV apps, ARCore overlays, sensor-driven tracking, route guidance logic, and local database-backed mobile systems. I’m confident I can deliver clean source code, documentation, error recovery, and a scalable foundation for future SLAM/ML upgrades. Please share your mall map format, landmark dataset expectations, and preferred timeline so I can propose the best technical plan. regards Cedric

The difficult part here is not AR rendering itself, it’s keeping localization stable once visual detection confidence drops in long corridors, crowded areas, or repeated storefront patterns. Most indoor AR demos break exactly there. I have worked on mobile CV pipelines using CameraX + OpenCV where sensor drift and relocalization became the real engineering problem, not the UI layer. Your graph-constrained approach with confidence validation is the right direction for this kind of environment. I would split this into independent modules first: landmark detection/localization, sensor fusion + dead reckoning, then AR navigation/rendering on top so rerouting and drift correction stay isolated and testable. One thing I would like to clarify early: will the mall graph, landmark positions, and store embeddings already exist, or is the app also expected to include the mapping/data collection pipeline?

Hello, In my opinion, the problem of this project is that achieving accurate indoor navigation requires robust integration of AR, computer vision, and sensor fusion technologies. I will implement a clean architecture leveraging CameraX for real-time landmark detection and OpenCV for image processing, ensuring efficient data flow through a well-defined localization pipeline. The navigation system will utilize A* pathfinding, integrating sensor data for drift correction and continuous tracking. I will prioritize modularity to facilitate future updates while ensuring thorough error handling and recovery mechanisms. The deliverables will include full Android source code, a modular codebase, comprehensive documentation, and a production-ready UI, alongside the complete localization and AR navigation systems. My extensive background in Android development and AR applications ensures high-quality output. I am open to work immediately. Best Regards.

The freelancers bidding here are treating this like a basic map app. They don't realize that building a custom Visual Positioning System (VPS) with Graph-constrained PnP solvers and Dead Reckoning is an elite Computer Vision engineering task, not a UI job. As a Senior AR & Computer Vision Architect, my approach tackles the real bottlenecks of indoor mall navigation: • Drift & Magnetic Interference: Standard compasses fail inside steel-framed malls. I implement a robust Extended Kalman Filter (EKF) combining your IMU sensor fusion with ARCore's odometry to minimize dead-reckoning drift between visual relocalizations. • Optimized Visual Pipeline: Feeding CameraX frames directly into quantized TFLite/ONNX models for fast embedding extraction, matching them against a local vector database to achieve real-time PnP pose estimation without thermal throttling the CPU. • Graph-Constrained Routing: A* pathfinding strictly clamped to your navigational meshes, ensuring AR projection overlays never guide users through physical walls or closed stores. Feel free to review my profile portfolio for live, production-grade architectural systems I’ve engineered. Critical question: Malls suffer from dynamic lighting and constant store storefront changes. Are your landmark embeddings fetched dynamically via an edge-cloud sync to adapt to these changes, or are we pre-packaging a static ONNX model within the APK for purely offline matching?
