SkyVision: APDT Few-Shot Self-Training for Early Smoke & Fire Detection

DaoAI SkyVision 0-code video surveillance AI platform (featuring on-site hour-level custom model training, behavior/event recognition, real-time edge box alerts, 100% on-premise data security, and DaoAI World semantic understanding) leverages APDT few-shot self-training to reduce false alarms for early smoke and fire detection in large industrial parks from 15% to 2.7%, while shortening average response time by 7.5 minutes, significantly enhancing emergency security efficiency and reliability. In the realm of emergency and smart security, early detection of smoke and open flames is critical, directly impacting life safety, property protection, and business continuity. Traditional security systems face numerous challenges in initial fire detection, especially in complex and dynamic industrial environments, where false alarms and missed detections are common, severely compromising the practical effectiveness of warning systems. DaoAI is dedicated to providing more precise and efficient security solutions through advanced AI technology.

Pain Points: Why This Hurdle Is Difficult to Overcome

In large industrial parks, traditional smoke and open flame detection solutions face multiple dilemmas. Firstly, video analysis systems based on traditional image processing or fixed rules suffer from high false alarm rates in complex industrial scenarios. For instance, actual data shows that a certain chemical park, before adopting smart security systems, experienced false alarm rates as high as 15% due to factors like steam, dust, welding sparks, and reflections. This led to security personnel being overwhelmed and developing alarm fatigue, potentially causing genuine fire incidents to be overlooked. Secondly, traditional systems have a relatively high missed detection rate for specific smoke types generated by new materials or faint flames, especially in the initial stages, making it difficult to identify them accurately at the earliest possible moment. Thirdly, traditional solutions have long model update cycles and poor adaptability to new scenarios. When the park environment, production processes, or equipment changes, models cannot adapt quickly, leading to a decline in detection performance. For example, after a production line upgrade, a steel mill's original detection system significantly lost its ability to distinguish between smoke/dust and sparks, requiring weeks or even months for model retraining and deployment, during which security risks surged. Furthermore, traditional solutions often rely on cloud computing, leading to increasing concerns about data transmission delays and privacy. For industrial enterprises dealing with sensitive production data, 100% on-premise deployment is a strict requirement. The current industry hot topic, challenges in accuracy and real-time performance of open-source AI security detection systems based on large models for abnormal behavior recognition in video surveillance, precisely reflects the bottlenecks of traditional solutions: how to strike a balance between the powerful generalization capabilities brought by large models and the need for high precision and low latency in specific scenarios.

The root cause of these pain points lies in the lack of adaptive learning capabilities to environmental changes and the inability to precisely capture subtle features in traditional solutions. For example, in chemical parks, when steam leaks from equipment pipelines, its visual characteristics are very similar to initial smoke, making it difficult for traditional algorithms to distinguish; in metal processing workshops, welding sparks are easily confused with initial open flames. All these demand AI systems with extremely strong scene understanding, feature extraction, and few-shot learning capabilities to cope with the ever-changing industrial sites.

Technical Principles

The core advantage of DaoAI SkyVision 0-code video surveillance AI platform lies in its innovative APDT (Adaptive Pre-training and Dynamic Tuning) few-shot self-training technology. This technology first leverages the unified foundation and semantic understanding capabilities provided by the DaoAI World model to pre-train a base model with powerful perception of general visual features such as various types of smoke, flames, and abnormal behaviors. This enables SkyVision to possess initial generalized recognition capabilities when facing new scenarios, without requiring training from scratch. Building upon this, APDT introduces an efficient dynamic fine-tuning mechanism. When a customer deploys SkyVision in a specific scenario (e.g., a factory workshop), they only need to provide a very small number (e.g., 1-20) of smoke or open flame sample images, and the system can complete adaptive training of its own model within hours on-site. This process uses deep transfer learning and meta-learning algorithms to quickly adapt the pre-trained model to the unique visual characteristics of the target scene, such as distinguishing microscopic texture differences between steam and smoke, or recognizing faint sparks generated by specific industrial equipment. Compared to traditional rule-based AOI or manual inspection, SkyVision's APDT technology significantly improves recognition accuracy and efficiency. For example, in one case, through APDT few-shot self-training, the DaoAI SkyVision system reduced the missed detection rate for initial smoke to below 0.8%, whereas traditional solutions typically struggle to achieve below 5%.

Specifically, APDT technology optimizes loss functions and attention mechanisms, enabling the model to learn critical discriminative features from limited annotated data while suppressing background noise and irrelevant interference. For instance, SkyVision can perform fine-grained modeling of dynamic features such as smoke dispersion patterns, color changes, and brightness gradients, as well as physical characteristics like flame flicker frequency and color saturation. Furthermore, real-time alerting from edge boxes ensures immediate recognition results, and combined with the 100% on-premise data security strategy, it meets industrial customers' stringent requirements for data security and real-time response. This hybrid AI architecture, which combines the understanding capabilities of general large models with on-site few-shot adaptive learning, is key to DaoAI SkyVision's breakthroughs in the emergency security domain.

Typical Application Scenarios

• **Smoke Detection in Large Warehousing and Logistics Centers:** In open, high-rack warehouse environments, traditional point smoke detectors are slow to respond. SkyVision deploys high-definition surveillance cameras and uses AI algorithms to monitor for initial smoke signs in any area of the warehouse in real-time. The challenge lies in distinguishing dust, mist, and actual smoke, which the DaoAI system can effectively address through APDT training to reduce false alarms.
• **Open Flame Pre-warning in Chemical/Petrochemical Plant Areas:** Chemical parks are highly flammable and explosive, where even a tiny spark can cause disaster. SkyVision monitors critical areas such as reactors and pipe flanges in real-time to identify open flames caused by leaks. The difficulty lies in thermal radiation interference in high-temperature environments and background complexity, where the DaoAI World model offers better anti-interference capabilities.
• **Fire Safety Monitoring in Data Centers:** Data centers have dense equipment and complex wiring, and initial fires often start from localized overheating. SkyVision can detect trace smoke or faint flames in abnormal hot spots, providing earlier warnings than traditional temperature sensors. Challenges include the effect of server fan airflow on smoke dispersion and lighting variations, which the DaoAI solution can effectively manage.
• **Smoke and Fire Monitoring in Underground Parking Lots/Tunnels:** In enclosed or semi-enclosed spaces, smoke spreads rapidly, leaving a short escape window. SkyVision can capture smoke and open flames caused by vehicle spontaneous combustion or accidents at the earliest moment, linking with ventilation systems and evacuation instructions. Difficulties include vehicle exhaust, dim ambient light, and obstructions from traffic flow, where DaoAI SkyVision demonstrates robust performance.
• **Early Fire Detection on Factory Production Lines:** In flammable areas such as paint shops or woodworking shops, sparks or smoke may be generated during production. SkyVision monitors production lines in real-time, immediately alerting upon detecting any abnormal fire, preventing incidents from escalating. The challenge is distinguishing small amounts of smoke or sparks generated by production equipment operation from actual fires, which DaoAI APDT few-shot self-training can precisely learn and differentiate.

Implementation Case Study

A large industrial park, spanning several square kilometers and encompassing various production workshops, storage areas, and office buildings, faced immense pressure on its emergency security system. Previously, the park primarily relied on traditional smoke and temperature sensors and manual patrols. However, due to the complex park environment, with significant steam emissions, welding operations, and dust generation, the traditional system generated over 200 false alarms monthly (production line data), leading to security personnel fatigue and desensitization to genuine fire alarms. To address this pain point, the park introduced the DaoAI SkyVision 0-code video surveillance AI platform. Before deployment, the park's false alarm rate for early smoke and open flame detection was as high as 15% (production line data), with an average response time exceeding 10 minutes. During project implementation, the DaoAI team utilized the APDT few-shot self-training capability. By collecting only 5-10 typical smoke/open flame or interference source images for specific environments within the park (e.g., paint shops, oil depots, warehouses), customized models were trained and deployed on-site within hours. In this case, the DaoAI SkyVision 0-code video surveillance AI platform successfully reduced the early smoke and fire false alarm rate by 82%, from 15% to 2.7% (on-site park data), while shortening the average response time by 7.5 minutes (customer feedback data), significantly improving emergency response efficiency.

DaoAI SkyVision not only reduced our false alarm rate to single digits, but more importantly, it allowed our security team to focus on real threats instead of being drained by false alarms.
