Combine Harvester Camera Parameter Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing agricultural harvesting machines face inefficiencies in adjusting camera parameters for analyzing crop flow images, as settings and analysis results are displayed on different monitors, making real-time adjustments of camera sensitivity for determining broken grain and non-grain fractions difficult.
Innovation Solution
The camera parameters are adjusted by simultaneously displaying the real image of the crop flow, the determined crop parameters, and a camera parameter change module on a common monitor, allowing operators to compare and adjust camera sensitivity in real-time to match the actual crop conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If camera parameters are adjusted using separate monitors for setting and display, then the system provides dedicated control and information display, but the operator cannot efficiently adjust camera sensitivity in real-time to match actual crop conditions
Solution Approach 1:
The patent combines the camera parameter setting interface and the crop parameter display interface into a single integrated display unit. This allows the operator to simultaneously view the real image of crop flow, the determined crop parameters (broken grain fraction, non-grain fraction), and the camera parameter adjustment controls in one location, enabling immediate comparison and adjustment without switching between separate monitors or menus.
2Measurement precision
If camera parameters are adjusted without real-time visual feedback, then the system maintains simple display architecture, but the operator cannot accurately correlate parameter changes with actual crop conditions
Solution Approach 1:
The patent implements a feedback mechanism where the display unit shows both the real image of the crop flow and the determined crop parameters simultaneously with the camera parameter adjustment controls. This allows the operator to immediately see how changes in camera parameters affect the captured image and the calculated crop parameters, enabling precise calibration by comparing the visual representation with the analyzed data in real-time.

AI summary
The invention relates to an agricultural harvesting machine (1), in particular a combine harvester (1), with a control arrangement (2) comprising a camera (3) for recording a series of images of a passing crop stream, an evaluation device (4) for determining the crop parameter "broken grain fraction" (BKA) of the crop stream and/or the crop parameter "non-grain fraction" (NKA) of the crop stream based on an image analysis of the recorded image series, a visualization device (5) for displaying the determined crop parameter(s) "broken grain fraction" (BKA) and/or "non-grain fraction" (NKA) and a camera adjustment device (6) for operator-side modification of at least one camera parameter of the camera (3).It is proposed that the camera parameter(s) be/are changeable in such a way that the visualization device (5) displays the real image (10) of the crop flow, the real determined crop parameter(s) "broken grain fraction" (BKA) and/or "non-grain fraction" (NKA) and a camera parameter change module (9) of the camera adjustment device (6) simultaneously in such a way that a change of the camera parameter(s) can be coupled to a real-time comparison of the crop parameter(s) "broken grain fraction" (BKA) and/or "non-grain fraction" (NKA) determined by the evaluation device (4) with the real conditions shown in the real image (10).
