Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Operators of cranes with stereoscopic visualization apparatuses face difficulties in accurately interpreting depth information, leading to potential operating errors and damage.
Innovation Solution
The integration of a graphic auxiliary representation displayed over the stereoscopic camera image, using virtual reality goggles or 3D screens, to provide additional visual cues for depth perception, including markings and numerical displays to indicate spacing and dimensions relative to reference objects, and warning representations for proximity alerts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a stereoscopic camera image is displayed to provide depth information, then the operator receives three-dimensional spatial information, but the operator has difficulty correctly interpreting the depth information
Solution Approach 1:
The patent introduces a graphic auxiliary representation as an intermediary element that mediates between the stereoscopic camera image and the operator's understanding. This graphic overlay includes visual cues such as depth markers, distance indicators, and spatial reference elements that translate the three-dimensional depth information into more intuitively interpretable visual forms, thereby resolving the contradiction between providing depth information and making it easily interpretable
Solution Approach 2:
The patent employs color changes and visual variations in the graphic auxiliary representation to encode different depth levels and spatial relationships. By using distinct colors, brightness levels, or visual patterns to represent different depth zones or distance ranges, the system makes depth information more perceptible and easier to interpret without losing the three-dimensional spatial context
2Measurement precision
If the operator relies on depth information from the display device, then the operator can perceive spatial dimensions, but the operator experiences increased stress and reduced accuracy
Solution Approach 1:
The patent implements a feedback mechanism where the graphic auxiliary representation provides continuous visual feedback about depth and spatial relationships. This feedback loop allows the operator to constantly monitor and adjust their perception of depth information, reducing stress by providing confirmatory visual cues and improving both measurement precision and control reliability through enhanced situational awareness
Solution Approach 2:
The patent adds another visual dimension by overlaying graphic representations that provide additional spatial context. This dimensional enhancement transforms the basic stereoscopic image into a multi-layered visual display that incorporates depth markers, reference planes, and spatial annotations, thereby improving depth perception accuracy and control reliability without increasing operator stress

AI summary
A crane control for a crane includes a visualization apparatus which is adapted to generate a stereoscopically visualized camera image having depth information of a working environment of the crane for an operator of the crane control. The visualization apparatus is configured to generate in a representation overlying the camera image a graphic auxiliary representation representing a dimension which can be recognized per se in the camera image. Furthermore, the visualization apparatus includes a display device which displays the stereoscopically visualized camera image together with the overlying graphic auxiliary representation.
