Study Notes
Deep Learning-Based Object Detection in Augmented Reality
- Recent advancements in augmented reality (AR) and artificial intelligence (AI) are driving innovation across various fields and industries.
- Computer vision (CV) and AR technologies enable analysis and understanding of environments.
- This study systematically reviews research integrating AR/mixed reality (MR) and deep learning for object detection.
- Sixty-nine relevant papers were analyzed, focusing on: application analysis of deep learning-based object detection; and analyzing object detection computations on servers or local AR devices to understand the relationships between algorithms and AR technology.
- The advantages of deep learning-based object detection in solving AR problems and limitations hindering its widespread adoption are critically assessed.
- The integration of AR and CV shows promise for future innovation.
Augmented Reality Technologies and Devices
- AR technologies, first introduced in the 1960s, have advanced significantly in recent decades.
- AR systems comprise an image generating optical unit and a projection surface for displaying virtual content.
- AR devices are categorized into wearable devices, handheld devices, projection-based displays (spatial AR), and holographic displays.
- Wearable AR devices (headsets, goggles, glasses) are prominent, allowing hands-free interaction with digital content overlaid on the real world.
- Handheld devices (smartphones, tablets) offer simpler AR experiences, suitable for everyday use in navigation and gaming.
- Projector-based displays allow augmenting any surface without a mediating device.
- Holographic displays generate 3D content using diffractions of light, also capable of creating interactive experiences without intermediary devices.
Deep Learning-Based Object Detection
- Deep learning, particularly convolutional neural networks (CNNs), is frequently used in object detection.
- CNN algorithms break down images into segments, processing each portion to identify and classify objects.
- Region-based CNNs (R-CNN) use region-of-interest (ROI) to target object detection, improving speed.
- Fast R-CNN and Faster R-CNN algorithms enhance efficiency by reducing the number of regions to process.
- Mask R-CNN extends Faster R-CNN by adding a mask branch for object segmentation, enabling pixel-level accuracy.
- You Only Look Once (YOLO) processes entire images, offering fast real-time detection.
- Single Shot Multibox Detector (SSD) provides higher processing speed by eliminating the need for region proposal networks.
Review Methodology
- The review adhered to PRISMA guidelines to select relevant literature (Scopus, Web of Science, IEEE Xplore, ACM, and ScienceDirect).
- Research articles focused on both server/cloud-based and local device-based computation.
- 4835 initial records were reduced to 69 after rigorous screening based on relevance.
Object Detection in Augmented Reality
- Deep learning finds application in several industries.
- Manufacturing: AR-based systems using deep learning for assembly processes, tool/part detection, and providing instructions can enhance efficiency and reduce human errors
- Driving and Autonomous Vehicles: obstacle detection in augmented reality HUDs can enhance awareness and possibly reduce accidents. Algorithms detect signs, obstacles, and lanes to enhance driving safety.
- Assistance: AR used for navigation (especially for those with visual impairments); elderly assistance; or interactive product browsing in retail settings.
Computation Platforms
- Studies use either local AR devices or remote servers for object detection computations, each with advantages and disadvantages.
- Remote server processing typically offers faster speeds and greater computational power.
- Local device processing provides faster response times suitable for demanding applications/environments with low latency.
Study Results and Evaluation Metrics
- Most studies for object recognition involve images/video.
- Some studies focused on point clouds for 3D object detection.
- A combination of factors - computation efficiency, performance (accuracy/precision), and subjective user feedback (e.g., usability, error rates) - used for evaluating AR applications.
- Publication rates for this topic increased after 2016 and peaked in 2019-2020
Discussion and Conclusion
- Key challenges include: computational resource requirements, limited training datasets/models, and challenges related to latency and mobile/wearable device power limitations for real-time performance.
- User studies are scarce.
- The need for subjective measure is emphasized. Further consideration of user experience should enhance deep learning-based object detection in augmented/mixed reality.
