A Method of Container Image Rectification Based on Computer Vision

Container image correction is an important step in image identification preprocessing for container terminal automation. This paper proposes a method for image correction of multi-angle containers based on computer vision technology. The method includes two steps, the first stage is the filtering and straight-line detection of the container image. And in the second stage, the corresponding points are obtained according to the detected straight-line, and the perspective transformation is performed to achieve the corrective images, which can make it easy to detect and identify image text areas.
