Automating the process of collecting samples (e.g., images) from a vineyard can help monitor the grapes' condition with precision and prevent the spreading of diseases. A critical part of this task is the development of a robust localization algorithm so that (a) a robot is able to carry out the inspection process and (b) the vine-grower knows exactly which part of the vineyard has been inspected. In this paper, we propose a novel approach for enhancing the robustness of vSLAM by utilizing multiple stereo cameras and a novel method for detecting loops in homogeneous environments based on AprilTags, where state-of-the-art approaches may find it difficult to detect them. We test the accuracy of our method using a wheeled Robotic Platform (RP) in simulation and in a synthetic vineyard developed at CSL, NTUA \cite{csl_ntua}. The developed method achieves high accuracy in the localization of the RP in the vineyard and robustness even when a featureless object covers a large part of the Field of View of one camera. The developed software is available for testing at the CSL's bitbucket repository, i.e.:
