    Perception on Autonomous Driving (03/2019 - 10/2019)Computer Vision Research Engineer: Augmented Reality (03/2018 - 03/2019)My work focused mainly on processing vehicle-captured video data and developing large-scale 3D reconstruction algorithms. We have successfully captured and reconstructed an area of 7.5km by 7km with the total distance of around 120km. The achieved reconstruction accuracy is typically between 0.5m to 1m.1. Analyzed the causes of the incomplete reconstruction, and implemented partial BA technique to improve the completeness and quality of the reconstruction model;2. Implemented similarity correction technique for similarity transformation ambiguity caused by co-linearity of cameras to ensure that the recovered camera points upward;3. Implemented $L_\infty$ triangulation method to reduce the large re-projection error in the case where the depths of the structure vary greatly for cameras in the scene;4. Implemented Batched SfM algorithm, which is able to register a batch of eligible images, and effectively reduce the drifting error;5. Implemented an automated pipeline to divide large-scale image data into a grid of blocks and then perform multiple reconstruction tasks in parallel.
