CupixWorks Dimensional Accuracy Guidelines
TABLE OF CONTENTS
When using CupixWorks for spatial measurements and BIM overlay, please be aware of the following accuracy parameters:
Mapping Accuracy
Our 360° panoramic images are mapped to reference plans with positional accuracy within 2 inches (5 cm) at 70% probability and within 6 inches (15 cm) at 99% probability when the scene is challenging for 3D reconstruction like fast camera motion, poor-lit, or moving lights, etc.
BIM Overlay Visualization
When viewing BIM elements overlaid on panoramic images, apparent misalignments may occur due to:
- Panoramic image mapping accuracy
- Actual installation deviations
- Visual distortion inherent in equirectangular projections of 360° imagery
Measurement Accuracy
- Wall-to-wall measurements are typically accurate within 1-2% of actual dimensions.
- The shorter the distance, the more likely that a measurement will have notable errors.
- Reflective surfaces like mirrors, glass, or shiny floors frequently might not represent accurate 3D point clouds, potentially resulting in measurement deviations or inability to make measurements.
Factors affecting measurement precision include:
- Mapping accuracy of panoramic images at measurement points
- 3D point cloud coverage
- User point selection precision
- Panoramic image distortion
This accuracy information represents typical performance under standard conditions. Actual results may vary based on capture quality, reference plan accuracy, and measurement methodology.
