Abstract
An interactive camera calibration tool is presented that provides live feedback on the state of the calibration and produces tightly-distributed calibration parameters even when used by novices. Target positions are suggested by the calibration tool. Once the target has been aligned with the target positions, image data of the target is captured and used to compute calibration parameters. This process is repeated until the computed parameters meet the accuracy requirements specified by the user. A novel calibration quality metric is also leveraged to automatically determine whether a calibration is sufficiently accurate.
