Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information presentation devices struggle to generate an overhead-view image of a construction site when the number of imaging devices is limited, leading to inefficient management of vehicles at the site.
Innovation Solution
An information presentation device that generates a synthesized overhead-view image by combining images from at least one installed imaging device with images from drones or satellites, and optionally includes blind area computation and in-vehicle imaging to enhance safety and completeness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple imaging devices are installed to cover the entire construction site, then the overhead-view image coverage is improved, but the installation cost increases
Solution Approach 1:
The patent combines images from multiple imaging devices with satellite imagery to create a comprehensive overhead-view image. This merging approach allows the system to achieve complete site coverage without installing imaging devices throughout the entire construction site, thereby reducing installation costs while maintaining full area coverage
Solution Approach 2:
The patent uses satellite imagery as an intermediary to fill coverage gaps where imaging devices cannot reach. The satellite images serve as a complementary data source that provides overhead views of areas not captured by on-site imaging devices, eliminating the need to install additional expensive equipment in hard-to-reach areas
2Ease of manufacture
If imaging devices are limited due to cost constraints, then the installation cost is reduced, but the ability to synthesize complete overhead-view image deteriorates
Solution Approach 1:
The system merges limited on-site imaging device data with comprehensive satellite imagery to produce a complete overhead-view image. This combination compensates for the limited coverage of inexpensive imaging devices, ensuring no information is lost despite reduced equipment investment
Solution Approach 2:
The patent changes the data source parameters by incorporating satellite imagery with different spatial resolution and coverage characteristics. This parameter change allows the system to achieve complete site coverage using fewer and less expensive on-site imaging devices
3Device complexity
If only limited area is covered by imaging devices, then the device complexity is reduced, but the vehicle management efficiency deteriorates
Solution Approach 1:
The patent uses satellite imagery as an intermediary to provide comprehensive site coverage without requiring a complex network of on-site imaging devices. This approach maintains simple device architecture while enabling efficient vehicle management through complete site visibility
Solution Approach 2:
The system achieves multi-functionality by using satellite imagery to perform the coverage function that would otherwise require multiple distributed imaging devices. This universal approach to coverage simplifies the on-site device configuration while maintaining high vehicle management efficiency

AI summary
An overhead-view image of a work site is presented to an operator of a work machine even when the number of imaging devices at a construction site is lacking. The present disclosure provides an information presentation device for generating and outputting a terrain image relating to a construction site. The information presentation device includes a storage device that stores a program for performing a predetermined imaging process on the terrain image, and a processor for reading the program from the storage device and generating the terrain image. The processor performs: a process of using an image of the construction site acquired by at least one imaging device installed at a construction site, to acquire a first overhead-view image representing a current terrain of the construction site as viewed from above; a process of acquiring a second overhead-view image acquired by a method other than capturing by the imaging device installed at the construction site, and representing an original terrain of the construction site as viewed from above; and an image synthesis process of superimposing the first overhead-view image and the second overhead-view image to generate a first synthesized overhead-view image.
