In many camera-based applications, it is necessary to find the geometric relationship
between incoming rays and image pixels, ie, the projection model, through the geometric …

In order to determine camera parameters, a calibration procedure involving the camera
recordings of a checkerboard is usually performed. In this paper, we propose an alternative …

Background In the past few years, augmented reality (AR) has rapidly advanced and has
been applied in different fields. One of the successful AR applications is the immersive and …

Wide-angle cameras are widely used in photogrammetry and autonomous systems which
rely on the accurate metric measurements derived from images. To find the geometric …

During camera calibration, targets need to be placed in the depth of field of the lens to
ensure clear imaging, and they should take up proper proportions in the image. These …

Intrinsic projector calibration is essential in projection mapping (PM) applications, especially
in dynamic PM. However, due to the shallow depth-of-field (DOF) of a projector, more work is …

For the manufacture of visual system product, it is necessary to calibrate a massive number
of cameras in a limited time and space with a high consistency quality. Traditional calibration …

In this paper, we propose a new projector calibration method. It uses only a projector, a
scanner and a pinhole mask plate that can be easily prepared. In our method, pattern …
