Design Example: Identifying the Locations of Monuments in the Field Using Global Positioning System Device

Design Example: Identifying the Locations of Monuments in the Field Using Global Positioning System Device

Surveyors use Global Positioning System (GPS) technology to measure the precise location and elevation of points on Earth. In a recent survey, GPS receivers were used to determine the coordinates and elevations of two park monuments. The process involved careful mission planning, data collection, and correction to ensure accuracy. The survey began with mission planning to identify optimal satellite visibility and minimize Position Dilution of Precision (PDOP). A geodetic control point served as...

Area of Science:

Optics and Photonics
Human-Computer Interaction
Wearable Technology

Background:

Head-worn projection displays (HWPDs) are evolving for mobile applications.
Miniaturization and see-through capabilities are key challenges for practical HWPDs.
Augmenting the real world with digital information requires high-quality, lightweight optical systems.

Purpose of the Study:

To develop and demonstrate a miniaturized, lightweight binocular head-worn projection display (M-HWPD).
To achieve see-through capability for augmenting the real world with computer-generated images.
To evaluate the optical performance and integration of the M-HWPD prototype.

Main Methods:

Miniaturization of custom-designed projection optics.
Integration of optics with a commercial-off-the-shelf (COTS) retro-reflective screen.
Development of a lightweight (approx. 8g per eye) binocular display system.

Main Results:

Successful miniaturization and integration of optical components for the M-HWPD prototype.
Demonstration of clear, full-color stereoscopic image projection at three different focal depths.
Feasibility shown for superimposing computer-generated images onto real outdoor scenes.

Conclusions:

The developed M-HWPD offers a viable solution for mobile augmented reality.
The lightweight design and optical performance enable seamless integration of digital information with the real world.
This advancement paves the way for more immersive and practical wearable display technologies.
