Terminal Device Aligning Operator View With Stereo Camera Capture Range
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In construction site management, stereo cameras mounted on construction machines face challenges in aligning visual lines and capture ranges, leading to potential discrepancies between operator instructions and image-capturing device data, which can result in incomplete or inaccurate three-dimensional data generation.
Innovation Solution
A terminal device and image-capturing system that includes a capture data-receiving unit, display unit, and acquisition instruction-transmitting unit to ensure alignment and acquisition of desired capture data for generating three-dimensional data, with a work vehicle equipped with an image-capturing device capable of depth information, transmitting and receiving data to integrate and display relevant information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a stereo camera is mounted in a construction machine to capture image data, then three-dimensional data of the construction site can be generated, but the visual line of the operator and the visual line of the image-capturing device do not necessarily coincide, leading to potential inaccuracies in capture data
Solution Approach 1:
A terminal device is introduced as an intermediary between the construction machine's image-capturing device and the operator. This terminal device receives capture data from the image-capturing device, displays it to the operator, and allows the operator to send acquisition instructions based on the displayed information. This intermediary system bridges the gap between the operator's visual perspective and the image-capturing device's capture range, enabling accurate three-dimensional data generation while maintaining ease of operation.
2Reliability
If the operator manually instructs the image-capturing device to capture data, then capture data can be acquired, but there may be a difference between the capture range imaged by the photographer and the desired capture range, resulting in incomplete or inaccurate three-dimensional data
Solution Approach 1:
The terminal device provides real-time feedback by displaying capture data received from the image-capturing device to the operator. This feedback loop allows the operator to verify whether the desired capture range has been successfully captured and to send additional acquisition instructions if necessary. The feedback mechanism ensures complete and accurate three-dimensional data while minimizing the need for multiple capture attempts, thereby reducing time loss.
