Coordinate Measuring Sensor Visualization with Dynamic Scene Shifting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for visualizing sensor signals in coordinate measuring machines do not provide a clear and detailed representation, especially when the sensor moves relative to the workpiece, requiring significant effort to adapt the displayed scene, and often result in important details being obscured.
Innovation Solution
A method that combines a two-dimensional sensor image with a two-dimensional view image of a partial area of a three-dimensional scene, adjusting the view image by shifting it when the sensor moves, to ensure the sensor image remains within defined edges, allowing for efficient visualization without overwhelming the user with excessive scene information.

Engineering Contradiction Analysis
1Area of stationary object
If the entire scene is displayed to provide comprehensive context, then the user can see the overall environment, but important details of the sensor's current position and detected area become obscured
Solution Approach 1:
The scene is divided into multiple sub-areas, and the display dynamically selects and shows only the relevant sub-area where the sensor is currently positioned. This segmentation allows the system to maintain comprehensive context while focusing on detailed sensor position information without showing the entire scene at once.
Solution Approach 2:
The system transitions from displaying a two-dimensional entire scene view to a multi-dimensional representation that includes sensor position, detected area, and scene context layered together. This dimensional approach allows detailed sensor information to be overlaid on the scene without obscuring either element.
2Adaptability or versatility
If the sensor moves relative to the workpiece to access different areas, then measurement coverage is improved, but the displayed scene requires significant manual adaptation effort
Solution Approach 1:
The display system continuously receives feedback about the sensor's current position and automatically adjusts the displayed scene sub-area accordingly. This closed-loop feedback eliminates the need for manual scene adaptation, as the system autonomously tracks and repositions the displayed content to match the sensor's movement.
Solution Approach 2:
The system pre-configures the display to automatically track and follow the sensor's position. Before the sensor moves to a new area, the display is already set up to anticipate and adjust to the new position, eliminating the need for post-movement manual adjustment by the user.
3Measurement precision
If detailed sensor information is displayed to provide clear measurement context, then measurement precision is improved, but the display becomes cluttered with excessive information
Solution Approach 1:
The display applies different levels of detail to different regions: the sensor position and detected area are shown with high detail and prominence, while the surrounding scene context is displayed with lower detail. This local quality differentiation ensures measurement precision is maintained where needed without cluttering the entire display with excessive information.

AI summary
The invention relates to the visualization of sensor signals from an optical sensor (26) of a coordinate measuring machine or microscope, wherein: - the optical sensor (26) and a space for arranging a workpiece to be detected are movable relative to each other, - data from a three-dimensional scene (5) that is stationary relative to the space are received and/or available, - a two-dimensional sensor image (4) generated from image signals of the optical sensor (26), which depicts a spatial region of the space in a given relative position of the optical sensor (26) and the space, is repeatedly combined in the correct orientation with a two-dimensional view image of a partial region of the three-dimensional scene (5) generated from the data of the three-dimensional scene (5) to form a two-dimensional output image, and the output image is output for display by an image display device.- the two-dimensional view image has two directions corresponding to its two dimensions, along which image elements of the view image can be represented and are also represented when displayed by the image display device, wherein opposite edges (2a, 2b, 3a, 3b) are predefined for the view image with respect to at least one of the two directions, between which a central area of the view image is located, - if the sensor image (4) no longer depicts the same spatial area compared to a previous generation of the output image, because the optical sensor (26) and the space for arranging the workpiece to be detected have undergone a relative movement relative to each other, is checked during a repeated generation of the output image,whether – with reference to a previously generated output image when using the same view image as in the previously generated output image – the sensor image (4) would extend from the central area over at least one of the two opposing edges (2a, 2b, 3a, 3b), and, if this is the case, another two-dimensional view image is generated from the data of the three-dimensional scene (5), wherein the other two-dimensional view image captures a sub-area of the three-dimensional scene (5) shifted according to the relative movement.
