Increase Recognition Accuracy! Achieving Automation in Logistics with Sticker-Type AR Markers

Enhancing Recognition with Low-Reflection, Non-Glossy AR Markers

The logistics industry is facing challenges due to labor shortages, prompting continuous advancements in autonomous driving technology. One essential component for autonomous operations and picking systems is AR markers, which provide location and other vital information.

Traditional AR markers often struggle with recognition issues caused by reflections from factory lighting, sunlight, or the glossy surface of the markers themselves. In some cases, inadequate lighting can reduce contrast, making it difficult to detect AR markers effectively.

To address these issues, a specialized AR marker has been developed using light-absorbing materials. The black portions of these markers have low reflectivity, which enhances the contrast between black and white, leading to improved recognition accuracy. This article introduces these low-reflection AR markers as a solution to challenges in autonomous logistics.

Sticker-Type AR Markers: Easy to Install and Highly Effective

A newly developed AR marker, approximately 10×10 cm in size, is designed as a thin, lightweight sticker that is easy to install. Even when exposed to direct sunlight, these markers maintain their visibility without excessive reflection, ensuring that their patterns remain readable. The reverse side is equipped with adhesive tape, allowing them to be applied conveniently like labels or stickers.

Features of Low-Reflection AR Markers

These AR markers use light-absorbing materials, offering the following advantages:

• Reduced reflection for better recognition
• High contrast between black and white, improving detection by robots and drones
• Sticker-type adhesive backing, allowing for easy and lightweight installation

Due to their ease of use, these markers are applicable in various environments, such as warehouse shelves for autonomous forklifts, temporary events, store displays, promotional activities, and AR-based advertising.

The Secret Behind High Recognition Accuracy: "Fineshut" Material

The key to these high-recognition AR markers lies in the use of "Fineshut," a specialized black material designed for light absorption and reflection prevention. This material not only possesses exceptional optical properties but also maintains an ultra-thin profile of just 0.22mm. Due to these characteristics, it is even utilized for reducing stray light inside the mirror boxes of DSLR cameras.

Customizable AR Panels with Non-Glossy QR Codes

In addition to sticker-type markers, AR markers can also be fabricated on acrylic panels. This option is ideal for applications where adhesive tape cannot be used or where enhanced durability is required.
