Extrinsic calibration — aligning the coordinate frames of a LiDAR sensor and a camera — typically requires specialised targets or careful setup. A new arXiv preprint, ScreenCalib, proposes using an ordinary programmable display for this task. The display shows known visual markers and provides controlled geometry, which the calibration routine can use to establish the transformation between the two sensors.
According to the abstract, the approach reduces dedicated target preparation compared with conventional methods. Because the display is a common piece of hardware, the method may make rapid calibration more accessible in settings where custom targets are impractical.
