Distance Corrections

Distance Corrections

To achieve precise distance measurements, especially in surveying and construction, certain corrections must be applied to account for potential sources of error like the standardization errors, temperature variations, and slope adjustments.Standardization error emerges when measurement equipment undergoes changes, such as wear, repairs, or weather impacts. To address this, surveyors compare the equipment’s readings to a standard. This process identifies any deviation that might lead to...

Area of Science:

Computer Vision
Optical Engineering

Background:

Time-of-Flight (ToF) depth cameras are susceptible to systematic errors.
In-camera light scattering significantly degrades the accuracy of depth measurements.

Purpose of the Study:

To develop a novel model for correcting in-camera light scattering in ToF depth cameras.
To enhance the precision and reliability of depth sensing systems.

Main Methods:

A new calibration model based on raw data is proposed.
The model incorporates only one additional intrinsic camera parameter.

Main Results:

The developed approach effectively eliminates in-camera light scattering errors.
Significant improvements in the accuracy of ToF depth cameras were demonstrated.

Conclusions:

The proposed raw data calibration model offers an effective solution for in-camera light scattering.
This method enhances the performance and applicability of ToF depth sensing technology.
