Efficient active monocular fixation using the log-polar sensor
This paper applies a sensor which has been developed based on a model of primate vision to corner fixation. Fixation is critical for the log-polar sensor as many of the sensor’s advantages are demonstrated only under fixation. This paper presents a fast corner fixation algorithm using the log-Hough transform to find the dominant centre-most corner and aligning the optical axis with the corner. ...
متن کاملActive Monocular Fixation using the Log-polar Sensor
This paper presents a fast corner fixation algorithm for log-polar cameras. The algorithm uses the log-Hough transform to fixate on the dominant corner in the image by aligning the optical axis with the corner. The algorithm has been implemented in a real-time closed-loop control system, which exhibits stable behaviour as the tracking error minimises towards the image centre. This system demons...
متن کاملDynamic Fixation of a Moving Surface Using Log Polar Sampling
We describe the development and testing of a first-order motion estimation algorithm which maintains accurate fixation of features on surfaces undergoing three-dimensional motion, and determines the local affine motion parallax. The accuracy of the first-order flow estimation is much improved by the use of log-polar sampling. We investigate the contribution of fixation to this accuracy using sy...
متن کاملVisual Tracking using Kernel Projected Measurement and Log-Polar Transformation
Visual Servoing is generally contained of control and feature tracking. Study of previous methods shows that no attempt has been made to optimize these two parts together. In kernel based visual servoing method, the main objective is to combine and optimize these two parts together and to make an entire control loop. This main target is accomplished by using Lyapanov theory. A Lyapanov candidat...
متن کاملMonocular obstacle detection using reciprocal-polar rectification
Our obstacle detection method is applicable to deliberative translation motion of a mobile robot and, in such motion, the epipole of each image of an image pair is coincident and termed the focus of expansion (FOE). We present an accurate method for computing the FOE and then we use this to apply a novel rectification to each image, called a reciprocal-polar (RP) rectification. When robot trans...
