In all these fields, image contrast plays a crucial role. The main approach which has been applied to enhance grayscale images is the hybrid effect of histogram equalization (HE) and self-calibrated illumination method (SCIM). The main task is to apply Histogram Equalization (HE) to the ...
The vision hardware for the system, which includes a stereo camera and at least one illumination source that projects a pattern into the ca... M Bell,R Chin,M Vieta - US 被引量: 117发表: 2010年 Active Self-Calibration of Hand-Mounted Laser Range Finders In this paper, we propose a ...
the environment monitoring module is used for acquiring temperature signals, humidity signals and illumination signals; and the vibration signals output by the sensors are connected with the signal conditioning circuit for amplifying an analog to digital conversion circuit, and finally output through a di...
Calibration of the relationship between the scattering angle and the CCD pixel is a key part of achieving accurate measurements of rainbow refractometry.A novel self-calibrated global rainbow refractometry system based on illumination by two lasers of different wavelengths is proposed.The angular ...
vehicle; A light source (4a) disposed in a vehicle and operable to emit light, wherein when activated the light emitted by the light source (4a) illuminates an illumination field external to the vehicle, and the detection field of the sensor is configured to illuminate the illumination field....
Previously a miniaturised structured light (SL) illumination probe (1.9 mm diameter) has been developed to generate sparsely reconstructed tissue surfaces in minimally invasive surgery (MIS). The probe is inserted through the biopsy channel of a standard endoscope and projects a pattern of spots with...
It is a desire to know the geometry for distant cameras, because geometry is not influenced by, for example, drastic changes in object appearance or in scene illumination. However, the determination of the camera geometry is cumbersome. The paper tries to solve this problem and contributes in ...
The device has a video-projector (1) for emitting an illumination beam along an optical lighting path to form an image (3) on a projection screen. A video detection system receives a detection beam along an optical detection path from the screen, and detects a screen image captured by an ...
The optical sketch is shown in Figure 5, where a polarized collimating light is used as the illumination with its polarization direction rotated 45◦ to Y-axis of the world coordinate system. Afterwards, a convergent lens is inserted after the tested object and therefore, we can determine ...
