The present paper describes the experimentation in a controlled environment and real using different photosensors, such as infrared light emitting diode (IRLED-as receiver), photodiode, dependent resistor (LDR), blue LED for purpose of selecting those devices, which can be employed adverse conditions, sunlight or artificial sources. experiments that are described this confirmed phototransistor could used photosensor an Optical Scanning System (OSS), because they were less sensitive to...
The design of machine vision applications allows automatic inspection, measuring systems, and robot guidance. Typical industrial robots are based on no-contact sensors to give the information about environment. Robot's requires photosensors or video cameras make intelligent decisions its localization. Video used as image-capturing equipment too costly in comparison with optical scanning systems (OSS). OSS system provides spatial coordinates measurements that can be exploited solve a wide...

This article presents a 3-D anthropometric vision system, free of ionizing radiation for measuring the medial longitudinal arch (MLA) and angle (LAA) foot, essential evaluating foot disorders that can affect person's lifestyle. Existing 2-D techniques determining MLA based on tests have limitations because they exclude important information about such as pronation, dorsiflexion, rotation. To overcome these limitations, proposed system uses stereo landmark detection algorithm to measure LAA,...
Laser-based scanners are widely used in state of the art technologies that obtain physic dimensions environment. Either for positioning purposes or 3D scanning surfaces and objects, laser have become very powerful tools these areas. In terms new novel scanners, it's important to some ways determine statistical data supports its reliability. Therefore development ways, methods, can help this analysis becomes important.
Laser Scanners used for Structural Health Monitoring applications such as Pipelines Inspections normally needs Point Clouds from a large quantity of individual measurements that should be adjusted or post-processed to decrease overall point-cloud errors depending on scanner's characteristics. The posterior adjustment is commonly addressed by different mathematical methods computational algorithms. According application requirements machine learning, signal filtering, RANSAC algorithms are...
