High accuracy 3D surface information is required for many construction robotics tasks such
as automated cement polishing or robotic plaster spraying. However, consumer-grade depth …

In fringe projection profilometry system, the lens distortion of the projector is usually
represented with the distortion coefficients, but it will result in large residual. To compensate …

The 3-D shape measurement of high-dynamic-range (HDR) scenes based on structured
light projection is challenging because the conventional projection without considering the …

When a digital projector is applied in high precision applications, the intrinsic parameters
and distortion characteristics should be calibrated precisely. In this paper, a flexible full-field …

We present a novel method that allows for simultaneous geometric and radiometric
calibration of a projector-camera pair. It is simple and does not require specialized …

Digital projectors have been widely used in many accuracy-sensitive fields. Although some
calibration methods have been proposed to obtain the intrinsic parameters for a digital …

Aiming at the problem of the low accuracy of projector calibration in a structured light system,
an improved projector calibration method is proposed in this paper. One of the key ideas is …

An open-source framework for real-time structured light is presented. It is called “SLStudio”,
and enables real-time capture of metric depth images. The framework is modular, and …

Digital projectors have been widely used in many accuracy-sensitive fields and the projector
should be calibrated precisely. Different from the existing methods using a single camera …

The phase 3-D coordinate mapping (P3DM) is an efficient 3-D reconstruction method for the
in situ measurement. However, the conventional P3DM calibration method requires complex …
