Low Vision Identification and Detection of Simple 3D Objects with Severely Blurred Vision
METHODS. The experiment was conducted in an indoor testing space. We examined detection and identification of simple convex objects by normally sighted subjects wearing diffusing goggles that reduced effective acuity to 20/900. We used psychophysical methods to examine the effect on performance of important environmental variables: viewing distance (from 10–24 feet, or 3.05–7.32 m) and illumina...
متن کاملIdentification and detection of simple 3D objects with severely blurred vision.
PURPOSE Detecting and recognizing three-dimensional (3D) objects is an important component of the visual accessibility of public spaces for people with impaired vision. The present study investigated the impact of environmental factors and object properties on the recognition of objects by subjects who viewed physical objects with severely reduced acuity. METHODS The experiment was conducted ...
متن کاملSurface defect detection of 3D objects using robot vision
Purpose – The purpose of this paper is to develop a robot vision system for surface defect detection of 3D objects. It aims at the ill-defined qualitative items such as stains and scratches. Design/methodology/approach – A robot vision system for surface defect detection may counter: high surface reflection at some viewing angles; and no reference markers in any sensed images for matching. A fi...
متن کاملAnxious man with blurred vision
A 34-year-old man with history of stress presented to the emergency department with blurred vision in the left eye for the past week. There has been no vision change in his right eye. The vision acuity of the left eye was 20/100. The fundus examination revealed a localized serous detachment of the macula (A). The fluorescein angiography (B) and the ocular coherence tomography (OCT) (C) confirme...
