Harvester Surround-View Display With Integrated Vehicle Body Information
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies do not effectively display an overhead image of a harvester's surroundings, making it difficult for operators to understand the work environment and the state of the harvester, and existing display devices separate camera images and information regions, complicating the comprehension of vehicle body information.
Innovation Solution
A system comprising a harvester with front, rear, first side, and second side cameras that generate shot images, a storage unit for vehicle body data, an image compositing unit to create a composite image showing the vehicle body and its vicinity, and a display unit to present this image, ensuring a wide range around the harvester is visible and information is easily understandable.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If camera images and vehicle body information are displayed in separate regions, then the display can show both types of information, but it becomes difficult to grasp at a glance what the information is about and what part of the vehicle body it relates to
Solution Approach 1:
The patent combines camera images and vehicle body information into a single integrated display region. The display unit shows the vehicle body image with camera images and information superimposed or adjacent to the corresponding vehicle body parts, allowing operators to understand information context immediately without switching between separate regions.
2Area of stationary object
If multiple cameras are installed to capture a wide range of the harvester surroundings, then the coverage area increases, but the device complexity and installation difficulty increase
Solution Approach 1:
The patent uses a standardized camera module that can be installed at multiple positions (front, rear, left, right sides) with identical or similar specifications. This multi-functional camera system captures images of different vehicle body parts and surroundings, which are then processed and displayed together in a unified interface, reducing overall system complexity despite multiple units.
3Loss of information
If the display shows detailed vehicle body information and camera images, then the information completeness improves, but the display becomes more complex and harder to understand at a glance
Solution Approach 1:
The patent applies local quality by displaying different types of information in different spatial locations within the same display region. Camera images are shown adjacent to or superimposed on the corresponding vehicle body parts, while text information is placed in nearby areas. This localized arrangement maintains information completeness while improving readability and reducing perceived complexity.

AI summary
A harvester includes an image compositing unit and a display unit. The image compositing unit generates a composite image showing a vehicle body and the vicinity of the vehicle body based on shot images generated by a front camera 21, a rear camera 22, a first side camera 23, and a second side camera 24 and vehicle body data stored in a storage unit. The display unit displays the composite image generated by the image compositing unit. The front camera 21 is provided on a front part of a driving section 8, the rear camera 22 is provided on a rear cover part 14, the first side camera 23 is provided on an outer side part of the driving section 8 in a left-right direction of the vehicle body, and the second side camera 24 is provided on an outer side part of a threshing device 11.
