Construction Site Video Annotation With Labellerr

Construction sites are hazardous environments, where safety is important to prevent accidents and injuries.

A 2022 study published in the Journal of Construction Engineering and Management discovered that using AI-powered video analysis for safety monitoring on construction sites resulted in a 20 percent decrease in safety violations when compared with standard human monitoring methods.

One critical aspect of ensuring safety on construction sites is the proper utilization of safety kits by workers.

These safety kits typically include personal protective equipment (PPE) such as hard hats, safety vests, gloves, and goggles.

However, monitoring and enforcing compliance with safety kit usage can be challenging, especially on large-scale construction projects.

To address this challenge, the integration of computer vision technology has emerged as a promising solution.

By leveraging advanced image processing algorithms, computer vision systems can analyze real-time video feeds from construction sites to detect and identify workers wearing safety kits.

This enables construction managers and safety officers to proactively monitor compliance with safety regulations and take corrective actions when necessary.

However, the development of accurate and reliable safety kit detection models requires large annotated datasets for training machine learning algorithms.

Labellerr, a leading data annotation platform, offers solutions for annotating images and videos of construction sites, enabling the creation of high-quality labeled datasets essential for training precise safety kit detection models.

This integration of computer vision and Labellerr platform signifies a significant advancement in construction site safety management, ultimately enhancing the safety and well-being of construction workers.

Challenge With Construction Site Annotation

In the high-risk environment of construction sites, ensuring the safety and well-being of workers is important.

However, numerous challenges and needs present the critical importance of safety wear on construction sites.

Various construction activities, including Excavation, pouring concrete, welding, lifting (a crane activity), drilling, cutting, and painting, each present distinct hazards necessitating specific safety measures.

Annotating these activities accurately is essential for identifying potential risks and ensuring appropriate safety protocols.

Object Occlusion: Workers are continuously moving about building sites, and different supplies and tools may block a person's view. If this happens, annotators may have difficulty identifying safety equipment such as vests, helmets, or goggles in video frames.

Annotators may implement active learning by training models to prioritize frames that show clear views of workers' safety gear, eliminating the need to annotate poorly obstructed frames.

Low video quality : Dust, uneven lighting, and unusual camera angles are all frequent on construction sites. Because of these factors, it may be difficult to see details of safety gear or separate them from background noise.

Annotators may use  pre-processing techniques like noise reduction (dust removal), contrast adjustment (uneven illumination), and image sharpening to improve video quality.

Various Gear Types: Construction workers wear a variety of protective gear depending on the job and the risks involved. Consistent annotation may be challenging because to the wide range of vests, helmets, and high-visibility clothing, which can differ in brand, color, and style.

Pose Variation: Workers may not always be positioned directly in front of the camera, or even upright. Because posture changes can alter how clearly annotators can view workers' protective gear, it is critical that they can do so whether the workers are  climbing, sitting, or bending.

Annotators can use multi-view learning by training models with videos of safety equipment from various angles to increase detection accuracy independent of worker stance.

Background Clutter: The colors and patterns of signage, tools, and materials on construction sites all match, creating a visually complicated environment. To prevent false positives, annotators must be able to distinguish between protective clothing and seemingly unrelated background objects.

To reduce clutter and increase safety gear identification, annotators may use algorithms to differentiate workers from background (signage, tools) or use attention mechanism to focus mainly on workers.

The development of automated annotation tools like Labellerr can streamline this process, accelerating dataset preparation while maintaining annotation quality and reliability.
