RGB-D Camera extrinsic parameter automatically calibration

Purpose

Automatically detect the ground plane, build the world coordinate and estimate the extrinsic parameter of the moving camera.

Rquirement

• MATLAB R2016 or newer
• have mj2 decoder (support mj2 video)

Run

• Download demo videos, and move "color.avi" and "depth.mj2" to work directory.
• cd work directory
• run "main"

Result

Our method can automatically detect the ground plane. Based the detected plane, we build a world coordinate and estimate the extrinsic parameters of the RGB-D camera.
