What factors influence drift when using spatial anchors in dynamic environments?

Asked on Nov 12, 2025

Answer

Spatial anchors in dynamic environments can experience drift due to several factors related to tracking stability and environmental changes. Understanding these factors is crucial for maintaining anchor accuracy in applications using frameworks like AR Foundation or OpenXR.

Example Concept: Drift in spatial anchors is primarily influenced by environmental changes, such as lighting variations, moving objects, and occlusions, which can disrupt the visual or sensor-based tracking systems. Additionally, the precision of the device's internal sensors and the robustness of the spatial mapping algorithms play a significant role in maintaining anchor stability. Ensuring consistent environmental conditions and optimizing sensor calibration can help mitigate drift.

Additional Comment:

Ensure consistent lighting conditions to improve visual tracking reliability.
Minimize occlusions and dynamic changes in the environment to maintain anchor stability.
Regularly recalibrate sensors and update spatial maps to adapt to environmental changes.
Use robust algorithms that can handle variations in the environment for better anchor persistence.
