Embodiments provide for automated detection of a calibration object within a recorded image. In some embodiments, a system receives an original image from a camera, wherein the original image includes at least a portion of a calibration chart. The system further derives a working image from the original image. The system further determines regions in the working image, wherein each region comprises a group of pixels having values within a predetermined criterion. The system further analyzes two or more of the regions to identify a candidate calibration chart in the working image. The system further identifies at least one region within the candidate calibration chart as a patch. The system further predicts a location of one or more additional patches based on at least the identified patch.
