Dual Camera Teat Positioning for Dairy Milking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current dairy milking systems are inefficient and inadequate in terms of scalability and accuracy, particularly in locating and attaching milking equipment to dairy livestock, often distracting the animals and leading to accidental detachment of equipment.
Innovation Solution
A vision system utilizing multiple cameras, including a higher-resolution second camera, and a processor to determine the center coordinate of a dairy livestock's udder and teat position, accounting for historical data and reference points to improve teat location accuracy and secure attachment of milking equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a single camera is used to locate teats, then the system complexity is low, but the measurement precision of teat position is insufficient
Solution Approach 1:
The system divides the imaging task into two segments: a first camera captures the overall udder area to determine the center coordinate, while a second camera with higher resolution captures detailed teat positions. This segmentation allows each camera to be optimized for its specific function, achieving high measurement precision without requiring a single overly complex camera system.
Solution Approach 2:
The system transitions from a single-view imaging approach to a multi-dimensional imaging approach by using two cameras positioned at different locations. The first camera provides a broad view for udder center detection, while the second camera provides a focused high-resolution view for teat position detection, creating a complementary multi-dimensional measurement system.
2Reliability
If milking equipment approaches from the side of dairy livestock, then the attachment process is simple, but the livestock becomes distracted and equipment may detach accidentally
Solution Approach 1:
Instead of approaching the livestock from the conventional side approach, the system inverts the approach direction and attaches milking equipment from the rear of the livestock. This inversion reduces animal distraction and prevents accidental detachment while the vision system guides the attachment process to maintain operational simplicity.
Solution Approach 2:
The vision system acts as an intermediary that enables the rear-approach attachment method. By providing real-time visual feedback and guidance on teat positions, the vision system bridges the gap between the non-conventional rear approach and successful attachment, maintaining ease of operation while improving reliability.
3Measurement precision
If high-resolution imaging is used throughout, then the measurement precision is high, but the energy consumption and system complexity increase
Solution Approach 1:
The system applies local quality by using a second camera with higher resolution only in the specific region where precise teat position measurement is needed, while the first camera uses standard resolution for the broader udder area. This localized high-resolution approach achieves necessary measurement precision while reducing overall energy consumption compared to using high-resolution imaging throughout.
Data Source
AI summary
A system includes a first camera, a second camera, and a processor wherein the second camera has a higher resolution than the first camera. The processor is communicatively coupled to the first camera and the second camera and is operable to determine a center coordinate of an udder of a dairy livestock based at least in part upon visual data captured by the first camera. The processor is also operable to determine a position of a teat of the dairy livestock based at least in part upon the center coordinate and visual data captured by the second camera.
