Abstract:
In this paper, a time-varying delay output feedback control method based on the potential barrier function is proposed, which can solve the communication delay and field-of-view (FOV) constraints of Unmanned Ground Vehicle (UGV) clusters when communicating with ultra-wide-angle cameras. First, a second-order oscillator and an output feedback controller are utilized to feed back the position and direction of neighboring vehicles by exchanging control quantities and to solve the time-varying delay in the position computation of the ultra-wide-angle camera. Due to the limited target radiation ran

Abstract This paper presents a wireless endoscope with an ultra-wide FOV (Field of View) of 130° and HD resolution (1280×720 pixels). The proposed endoscope consists of a camera head, cable, camera controller, and wireless handle. The lens module with a 150° degrees AOV (Angle of View) is achieved using the plastic injection-molding process to reduce manufacturing costs. A serial CMOS image sensor using the MIPI (Mobile Industry Processor Interface) CSI-2 (Camera Serial Interface-2) interface physically separates the camera processor from the camera head. The camera head and the cable have a c

Abstract:
In this paper, we consider the Unified Camera Model and its properties, as well as investigate and apply the improved Double-Spherical one (DS-model) in the task of restoring exterior and interior orientation elements for a set of images with ultra-wide-angle fisheye lens. The use of panoramic cameras in photogrammetry issues is a new trend, while the spherical model fully inherits the properties of the classical central-projection sample. The mathematical concept of using it is presented, as well as the solution of the optimization problem of calculating the elements of the internal and exter

Abstract:
Rear view cameras are widely used in the automotive industry. They are used in modern car navigation systems to improve the driver’s perception of the situation behind the car. Ultra-wide-angle fisheye lenses are installed on the car for maximum coverage. But such images are not comfortable for human perception. Therefore, one of the main problems in using such cameras is fast algorithms for converting fisheye images into a set of images corresponding to wide-angle and normal virtual cameras, as well as constructing a “top view”. This work examines two image transformation algorithms, both of

Abstract:
Biodiesel is a desirable alternative fuel for the diesel engine due to its low engine-out soot emission tendency. When blended with petroleum-based diesel fuels, soot emissions generally decrease in proportion to the volume fraction of biodiesel in the mixture. While comparisons of engine-out soot measurements between biodiesel blends and petroleum-based diesel have been widely reported, in-cylinder soot evolution has not been experimentally explored to the same extent. To elucidate the soot emission reduction mechanism of biodiesel, a single-cylinder optically-accessible diesel engine was use
