April Tag Scale Bars 100mm L

Enhance the precision of your photogrammetry projects with our lightweight, durable scale bars equipped with april tags. These bars not only help you achieve accurate scaling in your 3D scans but also streamline your workflow in popular software such as RealityCapture, Metashape, and 3DF Zephyr.

The 36h11 AprilTags family offers high robustness to noise with a larger Hamming distance, minimizing misdetections and false positives. It provides improved detection range and balances compact size with 587 unique tags, ensuring reliability even at a distance. Widely supported in computer vision libraries, it’s ideal for robotics, photogrammetry, and AR applications in both indoor and outdoor environments.

Crafted from 5mm hard foam boards, these scale bars are designed to be ultra-light and robust, ensuring ease of transport and long-lasting use. Each tag is precisely spaced 100mm (10cm) apart, offering consistent measurements across your scans. We provide bars with four distinct groups of april tags, allowing you to use multiple bars within a single scan for increased flexibility and efficiency.

Advantages of using scale bars with coded targets:

• Improved accuracy: April tags enable automatic recognition by photogrammetry software, eliminating manual input and reducing errors in scaling your models.
• Workflow automation: Using april tags allows your software to automatically detect and calibrate the scale of your project, significantly speeding up your processing time.
• Consistency in measurements: The standardized 100mm spacing ensures reliable and repeatable results across different projects, crucial for professional-grade accuracy.
• Multiple bar use: With multiple groups of april tags, you can combine different bars within a single scan, enhancing your ability to scale larger areas with precision.
• Software compatibility: Fully compatible with leading photogrammetry tools, ensuring seamless integration into your existing setup.

Invest in our april tag scale bars for a more streamlined and accurate photogrammetry workflow, ensuring professional-level results with every project.
