Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional geodetic surveying devices face challenges in achieving precise object determination, especially when surveying from different perspectives, due to limitations in linking image data and requiring a high number of support points, which results in time-consuming processes and limited precision in shape and spatial extension determination.
Innovation Solution
The method involves object-point-independent scanning using progressive alignment changes of measuring radiation to generate a point cloud representing surface information, with precise single point determination and updating based on object point positions, allowing for rapid and precise object data linkage across perspectives.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional geodetic surveying devices use traditional point-by-point surveying methods, then measurement precision can be maintained, but the surveying process becomes time-consuming and less productive
Solution Approach 1:
The surveying process is segmented into two distinct modes: scanning mode for rapid data acquisition and single-point determination mode for high-precision measurement. This segmentation allows the system to optimize for either speed or precision depending on the specific task requirements, resolving the contradiction between productivity and measurement precision.
Solution Approach 2:
The system dynamically switches between scanning mode and single-point determination mode based on the surveying requirements. The measuring device can adaptively change its operational characteristics, combining the speed of scanning with the precision of traditional methods, thus achieving both high productivity and maintained measurement precision.
2Measurement precision
If a high number of support points are used for linking image data from different perspectives, then object determination precision improves, but the complexity of the surveying process increases
Solution Approach 1:
The invention extracts and separates the support point determination as a distinct single-point determination task from the overall object surveying process. By using a reduced number of strategically selected support points determined with high precision, the system simplifies the complexity of linking image data while maintaining object determination precision.
3Reliability
If traditional surveying methods are used for shape and spatial extension determination, then measurement reliability is maintained, but the time required for post-processing increases
Solution Approach 1:
The system performs preliminary actions by acquiring comprehensive scanning data and determining support points during the initial surveying phase. This preliminary data collection and processing eliminates the need for extensive post-processing, reducing time loss while maintaining measurement reliability through the use of geodetically precise single point determination.

AI summary
A method for surveying an object for and/or using a geodetic surveying device that include a derivation of an item of surface information at least for one object region, at least one geodetically precise single point determination for the object region, wherein a position of at least one object point is determined geodetically precisely, and an update of the item of surface information based on the determined position of the at least one object point. In some embodiments a scan to derive the item of surface information may be performed using object-point-independent scanning of the object region by progressive alignment changes of the measuring radiation, with a determination of a respective distance and of a respective alignment of the measuring radiation emitted for the distance measurement for scanning points lying within the object region, and having a generation of a point cloud which represents the item of surface information.
