Risley-prism-based tracking model for fast locating a target using imaging feedback

Abstract: Fast imaging tracking technology exhibits attractive application prospects in the emerging fields of target tracking and recognition. Smart and compact tracking model with fast and flexible tracking strategy can play a decisive role in improving system performance. In this paper, an effective imaging tracking model from a target to a rotation Risley prism pair embedded with a camera is derived by the beam vector propagation method. A boresight adjustment strategy using the inverse ray tracing and iterative ref… Show more

“…e abovementioned spatial structure can be used as the input of the image in the neural network, and the adjacent grid becomes the specific area of the image pixel, and the high-latitude feature map is obtained after convolution processing. Classification processing on the feature map is performed to obtain the corresponding coordinate position [22]. e coordinates of key nodes undergo affine transformation and can be rotated within a certain range of angles to construct gestures of different spatial structures.…”

“…By altering the angle of the prism, the Risley-prism-based image sensor realizes the deflection of the optic axis, which has the effect of enlarging the imaging field of view (FOV). The Risley-prism-based imaging sensor has a wide variety of applications in wide-area target search, recognition, tracking imaging, and laser scanning as a result of the ongoing advancement of related research [ 5 , 6 , 7 ].…”
