Photogrammetry procedures applied to anthropometry

Area of Science:

• Biomedical Engineering
• Anthropometry
• Digital Imaging

Background:

• Accurate anthropometric measurements are crucial for various applications, including ergonomics and clinical assessments.
• Traditional measurement methods can be time-consuming and prone to error.
• Digital photogrammetry presents a potential alternative for precise and efficient data acquisition.

Purpose of the Study:

• To evaluate the reliability of digital photogrammetry for human hand anthropometric measurements.
• To establish standardized procedures for its application in anthropometric surveys.
• To assess the accuracy and efficiency of this technique compared to conventional methods.

Main Methods:

• Developed a specialized platform to ensure consistent hand positioning and eliminate parallax errors.
• Created custom software for automated measurements from captured digital images.
• Validated measurements against a standardized cast using digital photogrammetry, calipers, and a Coordinate Measuring Machine (MMC).

Main Results:

• Digital photogrammetry demonstrated effectiveness in hand anthropometry with a precision coefficient below 0.940.
• The achieved precision is considered acceptable for anthropometric data collection.
• The method proved to be reliable, accurate, and efficient for large-scale surveys.

Conclusions:

• Digital photogrammetry is a reliable and accurate tool for conducting anthropometric surveys of the human hand.
• The technique offers greater efficiency and reduced difficulty in data collection, especially in field settings.
• Established procedures facilitate its consistent application in population studies.
