MSC-VO: Exploiting Manhattan and Structural Constraints for Visual Odometry

no code implementations5 Nov 2021 Joan P. Company-Corcoles, Emilio Garcia-Fidalgo, Alberto Ortiz

Under these premises, in this work, we introduce MSC-VO, an RGB-D -based visual odometry approach that combines both point and line features and leverages, if exist, those structural regularities and the Manhattan axes of the scene.

A DCNN-based Arbitrarily-Oriented Object Detector for Quality Control and Inspection Application

no code implementations19 Jan 2021 Kai Yao, Alberto Ortiz, Francisco Bonnin-Pascual

Following the success of machine vision systems for on-line automated quality control and inspection processes, an object recognition solution is presented in this work for two different specific applications, i. e., the detection of quality control items in surgery toolboxes prepared for sterilizing in a hospital, as well as the detection of defects in vessel hulls to prevent potential structural failures.

A Weakly-Supervised Semantic Segmentation Approach based on the Centroid Loss: Application to Quality Control and Inspection

no code implementations26 Oct 2020 Kai Yao, Alberto Ortiz, Francisco Bonnin-Pascual

It is generally accepted that one of the critical parts of current vision algorithms based on deep learning and convolutional neural networks is the annotation of a sufficient number of images to achieve competitive performance.

LiPo-LCD: Combining Lines and Points for Appearance-based Loop Closure Detection

no code implementations3 Sep 2020 Joan P. Company-Corcoles, Emilio Garcia-Fidalgo, Alberto Ortiz

Visual SLAM approaches typically depend on loop closure detection to correct the inconsistencies that may arise during the map and camera trajectory calculations, typically making use of point features for detecting and closing the existing loops.
