This paper studies the construction of 3D temperature distribution reconstruction system based on the binocular visual technology. First of all, since the thermal infrared camera is only sensitive to temperature, the traditional calibration method cannot be directly used in it. Therefore, the paper designs a thermal infrared camera calibration board to complete the calibration of the thermal infrared...
In this paper, we propose an improved fuzzy enhancement algorithm for the moving object detection and tracking. A new membership function is proposed based on the theory of fuzzy sets, which improves the traditional Pal-King fuzzy enhancement algorithm and overcomes the loss of gray information after the processing of enhancement. Since a gray image with multiple targets need more than one crossover...
This paper presents a current sensor for measurement of AC and DC. The sensor consists of two toroidal magnetic cores. One core works in fluxgate principle for the measurement of DC and low frequency AC. Another additional toroidal core is used as a current transformer for higher frequency application. Bidirectionally saturated fluxgate principle is used in this sensor to achieve better temperature...
In order to estimate Chlorophyll-a concentrations at high spatial-temporal resolution accurately over bay systems in the western Gulf of Mexico, a 2-step remote sensing algorithm using observations from the Medium Resolution Imaging Spectrometer (MERIS) is developed. Here, the approach is tested in Galveston Bay. First, atmospheric correction for the MERIS reflectance is performed to improve the quality...
This paper presents a novel method for the real-time apparent density measurement of the working fluid in outlet pipes of a stream-injection boiler. The measurement system consists of a vertical measuring pipe, a container with constant height and a differential pressure (DP) transmitter. The working fluid in the upper part of the vertical measuring section flows into the container which is connected...
