Simultaneous Calibration of Odometry and Head-Eye Parameters for Mobile Robots with a Pan-Tilt Camera [PDF]
Sensors, 2019 In the field of robot navigation, the odometric parameters, such as wheel radii and wheelbase length, and the relative pose of the optical sensing camera with respect to the robot are very important criteria for accurate operation.

Novel Geometric Calibration Method for Pan-Tilt Camera With Single Control Point [PDF]
IEEE Access, 2023 Pan-tilt (PT) camera is an indispensable part of the video surveillance systems due to its rotatable property and low cost. As the primitive output of the PT camera limits its practical applications, an accurate calibration method is required.

Design control system for Pan-Tilt Camera for Visual Tracking based on ADAR method taking into account energy output [PDF]
E3S Web of Conferences, 2021 In this paper, we propose a controller for a camera-based Pan-Tilt device. The approach uses the target image feature to steer the Pan-Tilt device to the target with random movement.

A Comprehensive and Versatile Camera Model for Cameras with Tilt Lenses [PDF]
International Journal of Computer Vision, 2016 We propose camera models for cameras that are equipped with lenses that can be tilted in an arbitrary direction (often called Scheimpflug optics). The proposed models are comprehensive: they can handle all tilt lens types that are in common use for machine vision and consumer cameras and correctly describe the imaging geometry of lenses for which the ...

Predictive tracking of an object by a pan–tilt camera of a robot [PDF]
Nonlinear dynamics, 2023 Moving-object tracking using a pan–tilt camera setup is quite a well-known task in robotics. However, the presented research addresses specific properties of the tracked object and introduces novel features to the pan–tilt camera control strategy.

Background subtraction with a pan/tilt camera
, 2010 Background subtraction is a common approach in computer vision to detect moving objects in video sequences taken with a static camera. Some background subtraction algorithms have been extended to support a pan/tilt camera but they are required to provide a background mosaic for motion estimation purposes. This thesis describes a system that avoids this

Visual Odometry from Two Point Correspondences and Initial Automatic Camera Tilt Calibration
VISIGRAPP, 2017 Ego-motion estimation is an important step towards fully autonomous mobile robots. In this paper we propose the use of an initial but automatic camera tilt calibration, which transforms the subsequent motion estimation to a 2D rigid body motion problem ...
