Solution Overview

Problem

Existing surveying systems require measurement operators to visually check measurement results from the same position as the measuring device, leading to poor workability in construction environments.

Innovation Solution

A surveying system comprising a measuring device and a portable terminal that utilize an AR marker to enable measurement data to be displayed on the terminal from a different position, correcting the displayed position based on the marker's recognition and incorporating a tilt sensor for data correction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If measurement operators visually check measurement results from the same position as the measuring device, then measurement accuracy is maintained, but workability and construction efficiency deteriorate

Engineering Contradiction:
ImproveworkabilityVSAvoidmeasurement accuracy
Core Design Contradiction:
Ease of operationVSMeasurement precision

Solution Approach 1:

The patent creates a virtual copy of the measurement scene by capturing images with a camera and overlaying measured data (distance, area, volume) as graphical information on the image. This allows operators to view measurement results from different positions without physically moving the measuring device, maintaining measurement accuracy while improving workability.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent introduces an image processing system as an intermediary between the measuring device and the operator. The system captures images, overlays measured data on the images, and displays the composite information, allowing operators to check measurement results from convenient positions while the actual measurement is performed from the optimal position.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If measurement operators check measurement results directly at the construction site, then construction efficiency improves, but system complexity increases

Engineering Contradiction:
Improveconstruction efficiencyVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent makes the measuring device multi-functional by integrating both measurement functions (distance, area, volume calculation) and imaging functions (camera capture, image processing, data overlay) into a single system. This allows the device to serve multiple purposes - performing measurements and providing visual feedback - without requiring separate complex systems.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent merges the measurement data display system with the image capture system, combining numerical measurement results with visual image information into a single integrated display. This consolidation improves construction efficiency by providing all necessary information in one interface while managing system complexity through integration rather than separate components.

Inventive Principle:
Principle #5Merging (Combining)

3Adaptability or versatility

If measured data is displayed on the measuring device only, then data accuracy is maintained, but operator flexibility and mobility deteriorate

Engineering Contradiction:
Improveoperator flexibilityVSAvoiddata accuracy
Core Design Contradiction:
Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The patent creates visual copies of measurement data by overlaying numerical information (distance, area, volume) as graphical elements on captured images. These visual representations can be displayed on portable devices at different positions, giving operators flexibility to view accurate measurement data from various locations without compromising data precision.

Inventive Principle:
Principle #26Copying

AI summary

A surveying system and method are provided that allow a user to visually confirm measurement data of a measurement target from a position different from the measuring device. The surveying system includes a measuring device and a portable terminal. The measuring device is movable and includes a measuring instrument for measuring a measurement target, an AR marker having a known positional relationship with a measurement reference position of the measuring instrument, a control module configured to convert acquired measured data into data referenced to the AR marker, and a communication module configured to transmit the converted data. The portable terminal includes a camera configured to capture an image including the AR marker, a terminal communication module for receiving the converted data, a terminal control module, and a display unit. The terminal control module is configured to recognize the AR marker from the image, generate an AR image based on the recognized marker and the converted data, and display the AR image on the display unit.
