Abstract: Systems and methods are provided for physically labeling structural features, such as weld joints in a pipeline, with pattern-based codes that uniquely identify respective features. The systems and methods are also provided for identifying the features based on imagery of the codes captured during subsequent inspection of the weld joints. In particular, the weld joints can be uniquely identified by encoding measured geographic coordinates within two distinguishable circular patterns that correspond to latitude and longitude, respectively. In addition, the pattern-based codes can be applied to respective weld joints using a contrast material such that the codes are revealed in the images of the weld joints captured during inspection. Furthermore, the systems and methods include analyzing the images captured during inspection to identify the inspected weld joints for the purpose of verifying that each weld joint was properly inspected in the field.
