Robust extrinsic calibration from pedestrians

作者：

Highlights：

• Proposal of a novel metric for vanishing line estimation, therein improving the accuracy of extrinsic calibration from pedestrians.

• Incorporation of WCS reference into the calibration, enabling the camera extrinsic parameters to be totally evaluated and further refined.

• Presentation of a benchmark on the PETS’09 (crowded) dataset, and evaluation of previous methods.
