Measuring abutment convergence angles using stereovision dental image processing system
PURPOSE The purpose of this study was to develop a dental image processing system using a three-dimensional (3D) camera and stereovision technology. The reliability of the system for measuring axial wall convergence angles was evaluated. MATERIALS AND METHODS The new system predicted 3D coordinate points from 2D images and calculated distances and angles between points. Two examiners measured...
متن کاملTraffic Flow Measuring System by Image Processing
In this paper, we show anew image sensor for measuring traffic flow. The image sensor is set at an intersection. The image sensor measures t r af f i c flow by vehicle tracking. The tracking is done by gray level pattern matching. Gray level pattern matching is suitable for outdoor use since it is robust against change of scene brightness. Then we provide the hardware for high speed gray level ...
متن کاملFragmentation measurement using image processing
In this research, first of all, the existing problems in fragmentation measurement are reviewed for the sake of its fast and reliable evaluation. Then, the available methods used for evaluation of blast results are mentioned. The produced errors especially in recognizing the rock fragments in computer-aided methods, and also, the importance of determination of their sizes in the image analysis ...
متن کاملComparison of the fracture resistance of dental implants with different abutment taper angles.
To investigate the effects of abutment taper angles on the fracture strength of dental implants with TIS (taper integrated screwed-in) connection. Thirty prototype cylindrical titanium alloy 5.0mm-diameter dental implants with different TIS-connection designs were divided into six groups and tested for their fracture strength, using a universal testing machine. These groups consisted of combina...
متن کاملImage Processing Traffic Flow Measuring System of Hokuriku Expressway
The section between Nadachi-Tanihama .Ni igata Prefecture and Asahi .Toyama Prefecture(59.9km) of the Hokur iku Expressway was opened on July the 20th in 1988. This means that all the line of the Hokuriku Expressway was opened. This area has 22 tunnels and we built ImageProcessing Traffic Flow Measuring System as the part of NEC ITV System. It consists of 11 image-processing equipents and 54 I ...
