Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In surveying, workers have to wait for each measurement point to be measured by the surveying instrument, leading to inefficiencies when measuring multiple points, as they cannot move to the next point until the current measurement is complete.
Innovation Solution
A system comprising a surveying instrument, a measuring marker, and an eyewear device that allows workers to designate and measure multiple points independently by synchronizing coordinate spaces and performing image analysis to calculate three-dimensional positions, enabling simultaneous measurement instructions and reducing wait times.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the surveying instrument performs automatic measurement of each measurement point sequentially, then measurement precision is improved, but productivity deteriorates due to workers having to wait for each measurement to complete
Solution Approach 1:
The system performs preliminary actions by having the imaging section capture images of measurement points in advance and the arithmetic device perform preliminary image analysis and three-dimensional position calculation before the surveying instrument completes the actual distance and angle measurements. This allows workers to designate multiple measurement points sequentially without waiting for each measurement to complete.
Solution Approach 2:
The system adds a new dimension of operation by introducing the eyewear device that allows workers to visually designate measurement points in real-time while the system simultaneously processes multiple measurement points in parallel through image analysis and coordinate space synchronization, transforming the sequential measurement process into a concurrent operation.
2Device complexity
If the surveying instrument searches for measurement points using traditional methods, then device complexity is kept simple, but loss of time increases due to lengthy search periods
Solution Approach 1:
The imaging section acts as an intermediary that captures visual information of measurement points and transmits it to the arithmetic device for analysis. This intermediary system enables rapid location identification without requiring the surveying instrument to manually search through its visual field, significantly reducing search time while maintaining relatively simple device architecture.
Solution Approach 2:
The system replaces the traditional mechanical search process of the surveying instrument with an optical and computational approach. The imaging section captures images and the arithmetic device performs automatic position identification through image analysis, substituting the manual or mechanical scanning process with automated optical detection and computational geometry.
