An artificial compound eye (ACE) is a bio-inspired vision sensor which mimics a natural compound eye (typical of insects). This artificial eye is able to visualize large fields of the outside world through multi-aperture. Due to its functioning, the ACE is subject to optical flow, that is an apparent motion of the object visualized by the eye. This...

The artificial compound eye is a new type of camera that has miniature volume and large field of view (FOV), while the captured image is an array of sub-images, and each sub-image captures a part of the full FOV. To obtain a complete image with a full FOV, reconstruction is needed. Due to the parallax between adjacent sub-images, the reconstruction...

In recent years, much attention has been paid to the electronic cluster eye (eCley), a new type of artificial compound eyes, because of its small size, wide field of view (FOV) and sensitivity to motion objects. An eCley is composed of a certain number of optical channels organized as an array. Each optical channel spans a small and fixed field of...

An artificial compound eye system is the bionic system of natural compound eyes with much wider field-of-view, better capacity to detect moving objects and higher sensitivity to light intensity than ordinary single-aperture eyes. In recent years, renewed attention has been paid to the artificial compound eyes, due to their better characteristics in...
Conference Paper
The recognition and parameters estimation of radar emitter signals are crucial techniques in signal processing of Electronic Intelligence. In this paper, a new method of radar emitter signals recognition and parameters estimation based on time-frequency atom is proposed, which is by introduced into the idea of non-orthogonal decomposition of signal...
Conference Paper
Multi-objective decision is involved in many fields, an objective, correct and stable validity decision is crucial problem in multi-objective decision. Set Pair Analysis theory is introduced to multi-objective decision model in this paper. The decision scheme is evaluated by using the idea of SPA, and then analyzes the result of decision model by u...

... Here, the geometry relationship of optical channels in eCley is derived and then the mathematical relation between the parallax and depth among unparallel neighboring optical channels is obtained to reconstruct the final image. In addition, Wu et al. also proposed an optical flow method for eCley to estimate the object movement [42], and multi-aperture images of eCley provided good constraints on the consistency of optical flow estimates. Although the ACE system has a similar structure with other imaging systems, like the integral imaging system [43] and light field system [44], and both can use the stereo principle to obtain the depth of objects, for eCley, the inherent offset between adjacent channels leads to an object that can only span at most three channels in one direction. ...
... MTF values of 98% and 10% of the lenses are greater than 0.34494452 and 0.35897793 respectively. From above data, the change amount of MTF values after tolerance analysis is very small, which can satisfy the requirement of image quality [16] . ...
... Jiang et al. considered the intensity transitional area and proposed a distance measurement method at the object edge and achieved subpixel precision [40]. Wu et al. considered the oblique incidence of the apertures and proposed a geometry-based 3D reconstruction method named G3D [41]. Here, the geometry relationship of optical channels in eCley is derived and then the mathematical relation between the parallax and depth among unparallel neighboring optical channels is obtained to reconstruct the final image. ...
... Artificial compound eye (ACE) is a type of camera with a miniature volume and large FOV. Different kinds of artificial compound eye systems have been proposed [1][2][3]. The ACE-captured image is an array of sub-images with slightly different viewpoints. ...
