Scanning Beam Device Adaptive Image Acquisition Modes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Scanning beam image acquisition devices face challenges in maintaining image quality and accuracy when moving, as they often use the same frame rate and resolution for both moving and stationary modes, leading to distortion and outdated images, which can hinder navigation and image quality.
Innovation Solution
Implementing different image acquisition modes based on the device's movement, with a higher frame rate during movement and higher resolution while stationary, using sensors or computational methods to monitor and switch between modes, allowing for adaptive scanning parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the same frame rate and number of lines of image resolution are used to acquire images both while moving and while stationary, then the device complexity is reduced and ease of operation is improved, but image quality deteriorates during movement due to distortion and outdated images
Solution Approach 1:
The patent implements dynamic adjustment of image acquisition parameters based on the movement state of the device. The system automatically switches between a first image acquisition mode (higher frame rate, lower resolution) during movement and a second image acquisition mode (lower frame rate, higher resolution) when stationary, resolving the contradiction between ease of operation and image quality by making the system adaptive rather than static
Solution Approach 2:
The patent changes the parameters of image acquisition based on movement detection. When movement is detected, the system adjusts the frame rate upward and number of lines downward; when stationary, it adjusts frame rate downward and number of lines upward, thereby optimizing image quality for each operational state while maintaining simple operation through automatic parameter adjustment
2Loss of information
If a higher frame rate is used during movement to reduce outdated images, then image currency is improved, but image resolution deteriorates due to fewer lines being scanned
Solution Approach 1:
The patent explicitly changes acquisition parameters based on operational mode: during movement, it increases frame rate and decreases number of lines to maintain image currency; when stationary, it decreases frame rate and increases number of lines to maximize resolution. This parameter adaptation resolves the contradiction by optimizing for the dominant requirement in each state
3Manufacturing precision
If a higher number of lines of image resolution is used while stationary to improve image quality, then image detail is improved, but frame rate decreases leading to outdated images during movement
Solution Approach 1:
The system dynamically adjusts the balance between frame rate and number of lines based on movement detection. When stationary, it prioritizes resolution with more lines and lower frame rate; when movement is detected, it switches to prioritizing temporal currency with higher frame rate and fewer lines, thus resolving the time-quality tradeoff adaptively
Solution Approach 2:
The patent implements parameter changes that inversely adjust frame rate and number of lines based on operational state. During stationary operation, it increases lines for quality while accepting lower frame rate; during movement, it increases frame rate while reducing lines, thereby resolving the contradiction between detail and timeliness
4Device complexity
If the scanning beam device uses fixed acquisition parameters, then device complexity is reduced, but adaptability to different operational states deteriorates
Solution Approach 1:
The system employs self-service through automatic movement detection and autonomous mode switching. The device monitors its own state and automatically adjusts acquisition parameters without user intervention, achieving high adaptability while maintaining simple operation. This resolves the contradiction by making the system self-adapting rather than requiring complex manual configuration
Solution Approach 2:
The patent implements feedback through movement detection that informs parameter adjustment. The system continuously monitors movement state and uses this feedback to automatically switch between acquisition modes, achieving adaptability through a simple feedback loop rather than complex predefined configurations

AI summary
A method of one aspect may include monitoring movement of a scanning beam image acquisition device. Images may be acquired with the scanning beam image acquisition device using a first image acquisition mode when the monitoring indicates that the scanning beam image acquisition device is moving. Images may be acquired with the scanning beam image acquisition device using a second image acquisition mode when the monitoring indicates that the scanning beam image acquisition device is substantially still. The second image acquisition mode is different than the first image acquisition mode. In one aspect, the first mode has a relatively higher frame rate and relatively lower number of lines of image resolution than the second mode.
