3D inspection methods for specular or partially specular surfaces
Maestro-Watson, Daniel (Mondragon Unibertsitatea. Goi Eskola Politeknikoa, 2020)Deflectometric techniques are a powerful tool for the automated quality control of specular or shiny surfaces. These techniques are based on using a camera to observe a reference pattern reflected on the surface under ... -
Calibración de sistemas de triangulación láser basados en cámaras Scheimpflug
Legarda Cristobal, Aritz (Mondragon Unibertsitatea. Goi Eskola Politeknikoa, 2015)The continuous improvement that exists in the economy, leads to generate new processes, new products or new concepts. Thanks to the continuous improvement mentioned before, the manufacturing industry has developed new ... -
Depth Data Denoising in Optical Laser Based Sensors for Metal Sheet Flatness Measurement: A Deep Learning Approach
Alonso, Marcos; Maestro-Watson, Daniel; Izaguirre Altuna, Alberto; andonegui, imanol (MDPI, 2021)Surface flatness assessment is necessary for quality control of metal sheets manufactured from steel coils by roll leveling and cutting. Mechanical-contact-based flatness sensors are being replaced by modern laser-based ... -
In-Line Dimensional Inspection of Warm-Die Forged Revolution Workpieces Using 3D Mesh Reconstruction
Alonso, Marcos; Izaguirre Altuna, Alberto (MDPI, 2019)Industrial dimensional assessment presents instances in which early control is exerted among “warm” (approx. 600 ºC) pieces. Early control saves resources, as defective processes are timely stopped and corrected. Existing ... -
Labor Induction failure prediction based on B-Mode Ultrasound Image Processing using Multiscale Local Binary Patterns
Arana-Arexolaleiba, Nestor; Izaguirre Altuna, Alberto (IEEE, 2016)Labor induction is defined as the artificial onset of labor for the purpose of vaginal birth. Cesarean section is one of the potential risks of labor induction as it occurs in about 20% of the inductions. A ripe cervix ... -
Labor Induction failure prediction using Gabor filterbanks and Center Symmetric Local Binary Patterns
Arana-Arexolaleiba, Nestor; Izaguirre Altuna, Alberto (IEEE, 2018)Labor induction is defined as the artificial stimulation of uterine contractions aimed to induce vaginal birth. Occurring in about 20% of pregnancies labor induction has become one the most commonly practiced procedures ... -
Learning frequent behaviours of the users in intelligent environments
Aztiria Goenaga, Asier (Mondragon Unibertsitatea. Goi Eskola Politeknikoa, 2010)Intelligent Environments (IEs) are expected to support people in their daily lives. One of the hidden assumptions in IEs is that they propose a change ofu perspective in the relationships between humans and technology, ... -
A Multi Camera and Multi Laser Calibration Method for 3D Reconstruction of Revolution Parts
Alonso, Marcos; Izaguirre Altuna, Alberto (MDPI, 2021)This paper describes a method for calibrating multi camera and multi laser 3D triangulation systems, particularly for those using Scheimpflug adapters. Under this configuration, the focus plane of the camera is located at ... -
Optical Dual Laser Based Sensor Denoising for OnlineMetal Sheet Flatness Measurement Using Hermite Interpolation
Alonso, Marcos; Izaguirre Altuna, Alberto (MDPI AG, 2020)Flatness sensors are required for quality control of metal sheets obtained from steel coils by roller leveling and cutting systems. This article presents an innovative system for real-time robust surface estimation of ... -
Personalised Trachea Stent Designer: a Knowledge Feature
Ugarte, Done; Izaguirre Altuna, Alberto (Elsevier, 2012)Modelling of anatomical parts is usually tackled through triangulated models with specialised Bio-CAD applications. If features beyond anatomy are required, geometry is usually translated into NURBS geometry for further ... -
Ultrasound image processing in the evaluation of labor induction failure risk
Vasquez Obando, Pablo Jose (Mondragon Unibertsitatea. Goi Eskola Politeknikoa, 2017)Labor induction is defined as the artificial stimulation of uterine contractions for the purpose of vaginal birth. Induction is prescribed for medical and elective reasons. Success in labor induction procedures is related ...
