The navigation problem of autonomous vehicles in unstructured environments entails the ability of autonomous vehicle to plan an obstacle-free path in real-time between a sequence of waypoints. While there are several path planners in the literature based on optimization, sampling, and geometry, none of them are designed considering the most commonly used sensors, which currently utilize polar coordinates such as LIDAR and RADAR. Inspired by that, this work proposes an algorithm based on computational geometry to path planning step for autonomous vehicle navigation in unstructured environments. The proposed algorithm was evaluated in simulation and its results were compared following the BARN standardized metrics with classical methods. The proposed method achieves the lowest processing time whilst maintaining comparable performance results on the spatial-related metrics. It also outperforms the others on the dispersion metric, suggesting it is a more robust method with more planning options for complex environments.
