“…It has been demonstrated that wide-field methods can improve movement times and are prone to fewer errors for surgical tasks such as knot-tying and suturing [3,4]. Therefore, much research is done to increase the field-of-view to generate panoramic images of human cavities [5,6]. Moving wedge prisms can be used to direct the light path to various peripheral locations [7].…”

Endoscope cameras play an important and growing role as a diagnostic and surgical tool. The endoscope camera is usually used to provide a view of the scene straight ahead of the instrument to the operator. As is common in many remotely operated systems, the limited field of view and the inability to pan the camera make it challenging to gain a situational awareness comparable to an operator with direct access to the scene. We present a spectral multiplexing technique for endoscopes that allows for overlay of the existing forward view with additional views at different angles to increase the effective field of view of the device. Our goal is to provide peripheral vision while minimally affecting the design and forward image quality of existing systems.

In this study, we investigate methods to optimize the design of a panoramic annular lens (PAL) system. The design details of a PAL surveillance system, an anamorphic PAL surveillance system, a phone camera with a PAL attachment, and a PAL endoscope system are described. All these designs are optimized using a standard optical software package (Zemax). The results combine very good image quality with a modulation transfer function above 0.3, which is within the cutoff frequency of sensor chips.

Fan-ring interpolation method applied to the panorama unwrapping of the deep-hole parts

Image interpolation is a critical step in panoramic image unwrapping studies. Information calculated in the Cartesian coordinates, although broadly applied, applies to operation between rectangles that will destroy the compressed depth information. The polar coordinates, in contrast, can store depth information by handing between rectangle and circle to obtain more true images. A fan-ring interpolation based on the polar coordinates is proposed for unwrapping panoramic images in this study through replanning the pixel search path in the panorama, and is then supported by redefining third-order interpolation. We validate our method on synthetic and practical images. Compared with competitor models, the unwrapping image obtained from the fan-ring interpolation can provide better quality in subjective and objective evaluation with guaranteed accuracy.
