基于模仿学习的混合现实外部参数自动校正

Imitation Learning based Auto-Correction of Extrinsic Parameters for A Mixed-Reality Setup

Shubham Sonawani, Yifan Zhou, Heni Ben Amor

摘要:

在本文中,我们讨论了一种基于模仿学习的方法来减少由视觉传感器和投影仪组成的混合现实系统的校准误差。与盔装显示器不同,在该设置中,经由将场景投影到现实世界中,人类主体可获得增强信息。从本质上讲,相机和投影仪需要作为立体设置进行校准,以在3D空间中投影准确的信息。先前的校准过程需要多个记录和参数调整步骤来实现期望的校准,这通常是耗时的过程。为了避免这种繁琐的校准,我们训练一个CNN模型来迭代地校正给定QR码和投影图案的外部偏移。我们讨论了整个系统的设置,数据汇集的训练,和自动校正模型的结果。

英文摘要:

In this paper, we discuss an imitation learning based method for reducing the calibration error for a mixed reality system consisting of a vision sensor and a projector. Unlike a head mounted display, in this setup, augmented information is available to a human subject via the projection of a scene into the real world. Inherently, the camera and projector need to be calibrated as a stereo setup to project accurate information in 3D space. Previous calibration processes require multiple recording and parameter tuning steps to achieve the desired calibration, which is usually time consuming process. In order to avoid such tedious calibration, we train a CNN model to iteratively correct the extrinsic offset given a QR code and a projected pattern. We discuss the overall system setup, data collection for training, and results of the auto-correction model.
