A machine vision system for special shaped softgel inspection is proposed in this paper, which is composed of a pair of CMOS cameras and a diffuse blue illuminator. Because the flaws appear in softgel shells edge is difficult to detect, these two cameras are arranged symmetrically upon softgels with a certain angle to avoid blind area. An image segment method combined automatic threshold and edge...
Inside Santander city, we find two different historical parts, “la Puebla vieja”, oldest part of the city, where the cathedral is located and “la Puebla nueva”. A research team has been created with two purposes: study and make the architectural survey of historic building, through collaboration between the emerged company, 3D Intelligence, the Universidad de Cantabria, the Universit degli Studi di...
Since the efficiency of current automatic calibration system for high precision pointer meter is limited, this paper developed a new meter calibration system based on machine vision which applied a calibration method based on look-up table (LT) algorithm. Advanced machine vision and image processing algorithms are employed to recognize the readings automatically. Sufficient experimental results demonstrate...

Precision size measurements are widely used in industrial production such as candies and cookies in the food industry. However, it is a challenge to measure irregular objects in a universal device because of poor adaptability and low precision. In this paper, a high-precision measurement device for irregular objects based on machine vision is designed. It consists of a rotational adjustment platform,...
In the paper, the vision system for tracking of a center point of color markers with disturbance is presented. The authors have proposed the complementary filter algorithm (CF) as well as Kalman Filter (KF) to estimate a central position of the markers. To compute markers central position from marker area two different methods were used. First one is based on measurement of markers center mass. Second...
Distributed photovoltaic(PV) system is easily affected by the cloud cluster moving in the sky because of its small scale. The instantaneous shelter caused by the moving cloud cluster may lead to the output power of photovoltaic system fluctuation violently. The cloud cluster monitoring device was designed, which aims to track the solar trajectory and take photos of the cloud cluster. The centroid...
In this study, this paper focuses on the vision-based unmanned aerial vehicle (UAV) autonomous guided landing system's calibration problems. We combine multisensory to propose a fast calibration method in proceeding of autonomous landing of a UAV with ground-based multisensory fusion systems. The system components include image sensor, ultra-wideband radar (UWB), distance measurement module, two-axis...
This paper describes a common issues in architecture of the variety kind of vision-based sway sensors dedicated for the anti-sway solution as a feedback in close-loop systems. However, in the statement the author's attention was focused on the issue related with vision sensor architecture insensitiveness on actual exposure light conditions. The night vision functionality was obtained through use infrared...

A quality assurance approach to ensure proper camera zooming is proposed to replace existing manual process. Camera len-shake estimation is employed to measure camera quality during zooming. Typically, camera len-shake estimation has been performed by a human-operated procedure that requires repetitive operations in a time-consuming process. In this paper, a fast and efficient automatic estimation...
In this paper, we propose a method to extend the field of view (FoV) of cameras mounted on Micro Aerial Vehicles (MAVs). The idea is to stitch together appropriate sections of the panorama to the camera frame. The proposed system efficiently performs view extension by fusing fast tracking and feature descriptor matching into the stitching algorithm. The quality of the extended view is further improved...
In machine vision applications, Time-of-Flight (TOF) sensors like the Photonic Mixer Devices (PMD) became considerable alternatives to common 3D sensing devices. Because of the enormous progress in TOF-vision systems, nowadays 3D matrix cameras can be used for many applications such as robotic, automotive, industrial, medical and multimedia applications. This paper focuses on the range data resolution...
Bin picking has been a research topic for years because of the challenges in image processing, robot motion planning and tool system. However, much of the existing work is not applicable to most real world bin picking problems because they are too simplistic or not robust enough for industrial use. In this paper, we developed a robust random 3D bin picking system by integrating the vision system with...
