Single Camera Object Positioning via Simultaneous Feature Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for determining the position of an object in space require multiple cameras or successive camera positions, leading to high equipment costs and slow position determination due to the need for mathematically stable solutions that involve oriented optical axes and multiple images.
Innovation Solution
Simultaneously detecting at least two measurement characteristics with a single camera, using known coordinates in the object coordinate system to establish a relationship with the space coordinate system, allowing for position determination with increased speed and accuracy, and optionally using multiple cameras or recording positions to enhance precision.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple cameras or successive camera positions are used to determine object position, then measurement precision is improved, but device complexity and time consumption increase
Solution Approach 1:
The patent transitions from temporal sequencing (multiple images at different times) to spatial parallelism (multiple measurement characteristics detected simultaneously in one image). By detecting at least two measurement characteristics in a single recording device, the system achieves accurate position determination without requiring multiple cameras or successive images, thus reducing device complexity while maintaining precision.
Solution Approach 2:
The patent divides the object into multiple measurement characteristics (such as marked points, edges, or geometric features) that can be independently detected and processed. These segmented characteristics are then used to calculate the object's position in space, allowing accurate measurement with a single camera by analyzing multiple features simultaneously rather than requiring multiple cameras.
2Measurement precision
If multiple images are made from different positions to determine object position, then measurement precision is improved, but productivity decreases
Solution Approach 1:
The patent enables continuous position determination by detecting multiple measurement characteristics simultaneously in a single image capture. Instead of sequentially capturing multiple images at different positions and processing them one by one, the system captures all necessary measurement data in one continuous action, significantly improving productivity while maintaining measurement precision.
Solution Approach 2:
The patent shifts from temporal processing (sequential image evaluation) to spatial processing (simultaneous detection of multiple characteristics in one image). This dimensional change allows the system to determine object position in a single measurement operation rather than requiring multiple sequential steps, thereby increasing speed without sacrificing accuracy.
3Measurement precision
If optical axes are oriented differently in space to enable mathematically stable solutions, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent segments the measurement task into detecting multiple measurement characteristics on the object rather than requiring complex camera orientations. By identifying at least two distinct features (such as marked points or geometric elements) on the object and detecting them in a single image, the system achieves mathematically stable solutions without needing to orient multiple optical axes in different spatial directions.
Solution Approach 2:
The patent creates a two-dimensional representation (copy) of the three-dimensional object in a single image, capturing multiple measurement characteristics simultaneously. This 2D copy contains sufficient information to determine the object's position in space through computational methods, eliminating the need for complex camera positioning and multiple optical axis orientations that would otherwise be required.
