Automated Robust Metric Calibration Of Multi-Focus Plenoptic Cameras
2015 IEEE INTERNATIONAL INSTRUMENTATION AND MEASUREMENT TECHNOLOGY CONFERENCE (I2MTC)(2015)
摘要
The concept of plenoptic cameras has existed since the early 1900s, with recent advances in computational power making them a viable tool for industrial applications. Plenoptic cameras can give 3D information about the scene with one camera, one lens, and a single image. This is possible by placing a microlens array directly in front of the image sensor. The depth estimation is based on disparities observed in individual microlens images, similar to stereo camera approaches. To relate these so-called virtual depth units to metric distances, a camera calibration must be performed. This paper presents a robust, automated camera calibration technique, which introduces new ways to model a multi-focus plenoptic camera.
