Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image display and information providing apparatuses for supporting operations at sites like maintenance and construction do not consider the position and action of individuals, leading to potential misalignment or incorrect content projection due to mismatched camera images and actual operation states.
Innovation Solution
An information providing method that involves three-dimensional measurement of static objects and two-dimensional measurement of dynamic objects, transmitting data through a communication network to generate support data reflecting the environment and operator position, allowing for accurate projection of support data suitable for the operation scene.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If camera images are used to generate projection content, then the system can acquire visual information of the environment, but the images do not necessarily match the operator's position and action, leading to incorrect content projection
Solution Approach 1:
The measurement system is segmented into two distinct components: a three-dimensional measurement unit for static objects and a two-dimensional measurement unit for dynamic objects. This segmentation allows each unit to specialize in measuring specific types of objects with appropriate precision, thereby improving the accuracy of operation state information without requiring a single complex measurement system to handle all cases.
Solution Approach 2:
The system transitions from using only two-dimensional camera images to incorporating three-dimensional measurement data for static objects. This dimensional enhancement provides more accurate spatial information about the environment and operator position, enabling the system to generate projection content that accurately reflects the actual operation scene rather than relying solely on limited two-dimensional camera views.
2Measurement precision
If three-dimensional measurement of static objects and two-dimensional measurement of dynamic objects is implemented, then accurate support data can be provided, but the device complexity increases
Solution Approach 1:
Different measurement precisions are applied to different types of objects based on their characteristics. Static objects are measured with three-dimensional measurement for high spatial accuracy, while dynamic objects (operator position and action) are measured with two-dimensional measurement for sufficient positional tracking. This local quality approach optimizes measurement precision for each object type without uniformly increasing complexity across the entire system.
Solution Approach 2:
The information processing apparatus integrates multiple measurement data types (three-dimensional static object data and two-dimensional dynamic object data) into a unified environment grasping image. This multi-functional integration allows the system to handle diverse measurement inputs through a single processing platform, reducing the need for separate specialized systems and thereby managing complexity while maintaining high measurement precision.

AI summary
An information providing method includes: measuring a static object three-dimensionally in an environment, by a processor; sequentially measuring a position of a dynamic object in the environment, by the processor; transmitting measurement data of the static object measured to a predetermined information processing apparatus through a communication network; transmitting measurement data of the dynamic object measured to the information processing apparatus through a communication network; receiving support data rem the information processing apparatus based on an environment grasping image that is generated from the measurement data, of the static object and the measurement data of the dynamic object by the information processing apparatus; and presenting the received support data to the environment at predetermined timing, by the processor.
