Pixel-wise rational model for structured light system
Raúl Vargas, Lenny A. Romero, Song Zhang +1
This Letter presents a novel structured light system model that effectively considers local lens distortion by pixel-wise rational functions. We leverage the stereo method for init…
Corneal endothelium assessment in specular microscopy images with Fuchs' dystrophy via deep regression of signed distance maps
Juan S. Sierra, Jesus Pineda, Daniela Rueda +7
Specular microscopy assessment of the human corneal endothelium (CE) in Fuchs' dystrophy is challenging due to the presence of dark image regions called guttae. This paper proposes…
Three-dimensional multimodal medical imaging system based on free-hand ultrasound and structured light
Jhacson Meza, Sonia H. Contreras-Ortiz, Lenny A. Romero +1
We propose a three-dimensional (3D) multimodal medical imaging system that combines freehand ultrasound and structured light 3D reconstruction in a single coordinate system without…
MarkerPose: Robust Real-time Planar Target Tracking for Accurate Stereo Pose Estimation
Jhacson Meza, Lenny A. Romero, Andres G. Marrugo
Despite the attention marker-less pose estimation has attracted in recent years, marker-based approaches still provide unbeatable accuracy under controlled environmental conditions…
Hybrid calibration procedure for fringe projection profilometry based on stereo-vision and polynomial fitting
Raul Vargas, Andres G. Marrugo, Song Zhang +1
The key to accurate 3D shape measurement in Fringe Projection Profilometry (FPP) is the proper calibration of the measurement system. Current calibration techniques rely on phase-c…
