“…One of the acquisition systems that best approximates the direct capture of the omnistereoscopic function is a stereoscopic rig where the user controls D by selecting the panning direction of the camera arrangement [24]. Alternative acquisition methods use a cluster of stereoscopic panoramas to produce approximations of the binocular views predicted by our model [12].…”

Interactive visual media enable the visualization and navigation of remote-world locations in all gaze directions. A large segment of such media is created using pictures from the remote sites thanks to the advance in panoramic cameras. A desirable enhancement is to facilitate the stereoscopic visualization of remote scenes in all gaze directions. In this context, a model for the signal to be acquired by an omnistereoscopic sensor is needed in order to design better acquisition strategies. This omnistereoscopic viewing model must take into account the geometric constraints imposed by our binocular vision system since we want to produce stereoscopic imagery capable to induce stereopsis consistently in any gaze direction; in this paper, we present such model. In addition, we discuss different approaches to sample or to approximate this function and we propose a general acquisition model for sampling the omnistereoscopic light signal. From this model, we propose that by acquiring and mosaicking sparse sets of partially overlapped stereoscopic snapshots, a satisfactory illusion of depth can be evoked. Finally, we show an example of the rendering pipeline to create the omnistereoscopic imagery. Luis E.

“…In order to obtain multispectral images for remote sensing, multilinear CCD(Charge Coupled Device) sensors are often used on space camera working in the way of along-track scanning [1][2][3]. Usually quadrilinear CCD sensors are utilized with each line covered with different filters to represent red, green, blue and infrared band channels.…”

Multilinear CCD Sensor was often used on space cameras to obtain multispectral images with each line representing different band channels. However images of different band channels obtained at the same time didn't coincide as there were spaces between lines. Pixel numbers to be adjusted between images of different channels varied when the space camera worked by swaying forward and backward or adjusted row transfer period to compensate image movement. An automatic multispectral images synthesis algorithm of space camera was put forward on the basis of analysis of such phenomenon. In this algorithm a new evaluation function was used to determine pixel numbers to be adjusted and the image regions of each band channel to be clipped. In this way images of different band channels could be synthesized automatically to obtain an accurate colorful image. This algorithm can be used to dispose a large mount of images from space camera directly without any manual disposal so that efficiency could be improved remarkably. In validation experiments the automatic multispectral images synthesis algorithm was applied in synthesis of images obtained from outside scene experiment of a multispectral space camera. Result of validation experiments proved that the automatic multispectral images synthesis algorithm can realize accurate multispectral images synthesis of space camera and the efficiency can be improved markedly.

“…The stereoscopic camera rotation is around the Y axis exclusively (pitch rotation). This configuration describes acquisition methods that have been widely used over the last decade, whether using planar 9,10 or line sensors 11,12 for sequential acquisition. This configuration also models a widely used technique based on rotating an off-centered camera at regular angles θ i , where i ∈ f0; : : : ; N − 1g and N is usually large, producing a set of overlapped stereoscopic images of the scene.…”

Abstract. In recent years, the problem of acquiring omnidirectional stereoscopic imagery of dynamic scenes has gained commercial interest, and consequently, new techniques have been proposed to address this problem. The goal of many of these new panoramic methods is to provide practical solutions for acquiring real-time omnidirectional stereoscopic imagery for human viewing. However, there are problems related to mosaicking partially overlapped stereoscopic snapshots of the scene that need to be addressed. Among these issues are the conditions to provide a consistent depth illusion over the whole scene and the appearance of undesired vertical disparities. We develop an acquisition model capable of describing a variety of omnistereoscopic imaging systems and suitable to study the design constraints of these systems. Based on this acquisition model, we compare different acquisition approaches based on mosaicking partial stereoscopic views of the scene in terms of their depth continuity constraints and the appearance of vertical disparities. This work complements and extends our previous work in omnistereoscopic imaging systems by proposing a mathematical framework to contrast different acquisition strategies to create stereoscopic panoramas using a small number of stereoscopic images. © 2014 SPIE and IS&T
