Robust Outdoors Marker-Based Augmented Reality Applications: Mitigating the Effect of Lighting Sensitivity
Marker-based AR is widely used in outdoors applications enabling the augmentation of physical objects with virtual elements. However, the diversification of lighting conditions may severely affect the accuracy of marker tracking in outdoors environments. In this paper we investigate the effectiveness of geolocative raycasting, a technique which enables the real-time estimation of the user’s field of view in outdoors mobile applications, as a complementary method for enhancing the robustness of marker-based AR applications, thus mitigating the effect of lighting sensitivity.
