Abstract Many laser scanners depend on their mechanical construction to guarantee measurements accuracy, however, the current computational technologies allow us improve these by mathematical methods implemented in neural networks. In this article we are going introduce scanner technologies, give a description of our 3D and adjust measurement error previously trained feed forward back propagation (FFBP) network with Widrow-Hoff weight/bias learning function. A comparative analysis other...
The use of laser scanners as machine vision systems in Unmanned Aerial Vehicle (UAV) navigation offers a wide range advantages, when compared with camera-based systems. As one advantage, the measurement real physical distances can be mentioned, which results reduction times and thereby fast image processing UAV surrounding medium. In previous work, novel scanner namely Technical Vision System (TVS) was presented, implements continuous scan for determination 3D coordinates any object under...
This paper introduces a novel electronic circuit that has to be embedded in photodiode sensor as an integrated board for signal processing detects the energy center of optical signal, which represents most accurate position measurement from light emitter source mounted on structure (such building, bridge, or mine). The scanning structural health monitoring proposed is flexible system can operate with coherent incoherent source. It conformable any kind surfaces and data storage budget thanks...
Optical images and signals can be used to detect displacement in civil engineering structures. This paper presents a technical experimentation of vision-based technology artificial intelligence algorithms methodology for structural health monitoring new aging structures, by noncontact nondestructive system. The experimental study emphasis is on the outdoor urban environment, detection spatial coordinate order perform damage assessment. Also, contains both theoretical aspects fusion image...
Important engineering constructions require geometrical monitoring to predict their structural health during lifetime. Monitoring by geodetic devices, vibration-based techniques, wireless networks or with GPS technology is not always optimal; sometimes it impossible as shown in this article. A method based on measurements automation applying local optical scanners for proposed. Its originality and contribution the novel of precise measurement plane spatial angles. It considers robust...
In this paper, a novel method of frequency counting signals coming from automotive sensors is presented. The present helps to improve fast resolution output parameters typical frequency-domain (FDS). Controlling the electromechanical systems in today's cars task that requires high processing speed. proposed here has been tested under computer experiments, and theoretical results have shown it meets requirements speed response offset error measurement. Here, both principle rational...
Unmanned Aerial Vehicle (UAV) navigation requires Machine Vision Systems to determine physical values of near distanced objects. These machine vision systems must respond in sufficiently amount time using less scanning data from the observed A novel Technical System (TVS), which uses DC motors and laser triangulation spatial coordinates these objects, is offered used for UAV navigation. Present paper thereby shows implementation open-loop control algorithm, position TVS ray Field View (FOV)....
Quartz crystal microbalances (QCMs) are devices that have been proven to function as sensors for detecting specific chemical species; this usually requires the QCM is modified with a material capable interact desired compound. Zeolites an example of materials used sensitive layer. This due their capacity selective adsorption and large surface area; moreover, they can grow directly on surface. After, interaction between layer analyte, there mass change surface, which induces frequency shift...
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...
At last decade many approaches for non-contact measurement techniques object surfaces and 3D recognition have been proposed; but often they still require complex expensive equipment. Not least due to the rapidly increasing number of efficient hardware software system components, alternative low cost solutions are in great demand. We propose such a low-cost data acquisition fast surface registration by digitized points Cartesian coordinates matrix keeping. There is presented two examples...
