Schnuka: what is visual positioning system? How visual positioning system works

The components of vision system mainly include two aspects , One is the hardware component , One is software development . Let's first look at the hardware components .

1、 Hardware components

The hardware component of vision system mainly includes light source 、 The lens 、 The camera and the interface between the camera and the computer . The functions of these hardware are also as follows ： The light source is to enable the basic features of the detected object to be recognized ; The lens is to present a clear image of an object , The camera is mainly used to convert image information into familiar information , The interface between the camera and the computer is to store some video or digital information obtained above , Conduct research . The interface in the visual positioning system usually adopts the acquisition card or USB2.0.

2、 Software development part

The software development part of visual positioning system mainly consists of image acquisition 、 Camera calibration and acquisition of the coordinates of the sending target point are three parts .

The working principle of visual positioning system

cd With the rapid development of digital image processing and computer vision technology , More and more researchers use camera as the sensing sensor of fully autonomous mobile robot . This is mainly due to the limited amount of information perceived by the original ultrasonic or infrared sensors , Robustness is poor , The vision system can make up for these shortcomings .

ccd Visual location algorithm ： Filter based localization algorithms mainly include KF、SEIF、PF、EKF、UKF etc. . Monocular vision and odometer fusion can also be used . Use odometer reading as auxiliary information , The coordinate position of feature points in the current robot coordinate system is calculated by triangulation method , The three-dimensional coordinate calculation here needs to be carried out on the basis of delaying one time step .
