Angular measurement based on vision based AGV

Image processing technology is essential to visual navigation of AGV. Both the lateral offset and the direction deflection angle are key navigational parameters of the vision based AGV. The camera are installed at the bottom side of the AGV, which can be used to capture the white belt path of the ground. The lateral offset and the direction deflection angle are extracted by image filtering, threshold segmentation, edge detection, ribbon recognition, ribbon centerline fitting, and other related image preprocessing technology.According to the robustness and real-time performance of the image processing algorithm, the performance of image processing is verified by experiments.
