A concept of a simplified visual navigation system for mobile platforms

Głębocki R., Narkiewicz J., Zasuwa M.

Annual of Navigation

2007

No. 12

23-30

The concept of visual navigation is based on comparing images from navigation sensors with the data stored in the system memory. A control and navigation system based on information from simplified image sensors was developed for smart missiles. The system was based on images acquired by infrared sensors distributed along the rotating line. The system was tested by simulations giving adequate results. In this paper an extension of the system for application to other vehicles is presented. The main advantages of the proposed system are the ruggedness, simplicity and low cost.

Identification of characteristic points of the radar image on the basis of "contour" invariants comparison

Praczyk T.

Annual of Navigation

2005

No. 10

71-80

The article presents the one element of the autonomous maritime positioning system which task is the identification of characteristic points generated from the radar image. The system to fix position in automatic way requires extraction of characteristic points, their identification and subsequently in the last calculation step an application of classical methods of the radar navigation. The present article illustrates the characteristic point's identification algorithm based on the invariant representation of the radar image.
