Solution Overview
Problem
Existing portable geographical data collecting devices require significant time for data recording and post-treatment, leading to increased data complexity and potential duplication or omission of measurement points due to operator reliance on memory during quick data collection processes.
Innovation Solution
A geographical data collecting device equipped with a distance measuring unit, image pickup unit, display unit, tilt sensor, azimuth sensor, and control arithmetic unit that projects distance measuring light, takes images, and displays measuring points on a reference image, allowing for real-time confirmation and correction of measurement points, reducing data processing time and errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple images are taken for each measuring operation to collect comprehensive geographical data, then the completeness of measurement data is improved, but the time required for recording and data processing increases significantly
Solution Approach 1:
The patent combines multiple measuring operations into a single comprehensive image capture. By taking one image that encompasses the entire measurement area and then identifying multiple measuring points within that single image, the system eliminates the need to take separate images for each measuring point, thereby reducing recording time while maintaining data completeness
Solution Approach 2:
The patent performs preliminary image capture of the entire measurement area before conducting detailed measurements. By first acquiring a reference image that shows the full scope of the measurement area, the system prepares the groundwork for subsequent point identification, allowing operators to efficiently locate and measure multiple points without repeatedly capturing images
2Productivity
If data collection is performed quickly to cover the anticipated measurement range, then productivity is improved, but the accuracy of measuring point identification deteriorates due to operator reliance on memory
Solution Approach 1:
The patent implements visual feedback by displaying the captured image with identified measuring points overlaid on the screen. This allows operators to immediately see which points have been measured and which remain, providing continuous feedback that eliminates reliance on memory and prevents duplication or omission of measuring points while maintaining high collection speed
Solution Approach 2:
The patent creates a visual copy of the measurement area through image capture and displays it on the screen. This visual representation serves as a reference that operators can directly interact with, replacing the need to rely on memory for locating measuring points and enabling accurate identification without slowing down the data collection process
3Adaptability or versatility
If comprehensive geographical data including multiple objects and conditions are collected, then the versatility of the measurement is improved, but the complexity of data management and post-treatment increases
Solution Approach 1:
The patent segments the comprehensive measurement data by identifying and labeling individual measuring points within the single captured image. Each measuring point represents a distinct object or feature (such as trees, thickets, cracks, or landslide areas), allowing the system to organize complex geographical data into discrete, manageable units that can be easily processed and analyzed
