A new fundus camera technique to help calculate eye-camera magnification: a rapid means to measure disc size.
OBJECTIVE To find a simple means for calculating eye-camera magnification to permit estimation of true retinal object size from a retinal photograph. METHODS The position of the focusing knob on 3 different retinal cameras (TRC-50F and TRC-50X; Topcon America Corp, Paramus, NJ; and the CR6-45NM Non-mydriatic Retinal Camera; Canon Inc, Tokyo, Japan) was measured during optic nerve photography ...
متن کاملClinical assessment of rhodopsin in the eye. Using a standard fundus camera and a photographic technique.
A technique based on the method of differential fundus reflectometry is used to assess the availability of rhodopsin in the eye. A defined part of the dark adapted fundus is bleached by a short intense flash of light. The fundus is subsequently photographed in order to record the flux reflected from the bleached area, the optogram, and the surrounding unbleached region. This procedure requires ...
متن کاملA New Linear Camera Self-Calibration Technique
In this paper, a new active vision based camera self-calibration technique is proposed. The novelty of this new technique is that it can determine LINEARLY all the FIVE intrinsic parameters of a camera. The basic principle of our new calibration technique is to use the planar information in the scene and to control the camera to undergo several sets of orthogonal planar motions. Then, a set of ...
متن کاملA New Technique for Camera Self-Calibration
Self camera calibration based on purely rotational movement of camera receives the most attention among di erent self camera calibration methods due to its algorithmic and operational simplicity. The purely rotational approach, however, assumes camera rotates around its optical center, therefore yielding no translation. This assumption is not realistic since in practice the precise location of ...
متن کاملA Flexible New Technique for Camera Calibration
We propose a flexible new technique to easily calibrate a camera. It is well suited for use without specialized knowledge of 3D geometry or computer vision. The technique only requires the camera to observe a planar pattern shown at a few (at least two) different orientations. Either the camera or the planar pattern can be freely moved. The motion need not be known. Radial lens distortion is mo...
