Query: Calibration Venus: An Interactive Camera Calibration Method Based on
  Search Algorithm and Pose Decomposition   In many scenarios where cameras are applied, such as robot positioning and
unmanned driving, camera calibration is one of the most important pre-work. The
interactive calibration method based on the plane board is becoming popular in
camera calibration field due to its repeatability and operation advantages.
However, the existing methods select suggestions from a fixed dataset of
pre-defined poses based on subjective experience, which leads to a certain
degree of one-sidedness. Moreover, they does not give users clear instructions
on how to place the board in the specified pose.
