COMBINING FULL SPHERICAL DEPTH AND HDR IMAGES TO IMPLEMENT A VIRTUAL CAMERA
Image Based Lighting Point Clouds Registration Rendering Light Probe HDR
2015/7/31
Based on a real-world scene description consisting of N spherical depth images from a laser range scanner and M spherical (high dynamic range) texture images we present a method that allows to place a...
HDR IMAGING FOR FEATURE DETECTION ON DETAILED ARCHITECTURAL SCENES
Feature detection High dynamic range Tone mapping Architectural Scenes
2015/3/3
3D reconstruction relies on accurate detection, extraction, description and matching of image features. This is even truer for complex architectural scenes that pose needs for 3D models of high qualit...
A new impulse-type display named Local Blinking High Dynamic Range (HDR) LCD System was proposed, which utilized local dimming technology to achieve a local blinking effect that not only suppressed mo...
A 120Hz Local Blinking HDR system was proposed to significantly reduce MPRT down to 3.89ms and keep high brightness almost as well as conventional LCDs, that is distinct from the prior arts, such as B...
基于空间光调制器的HDR图像获取方法
高动态范围(HDR) 空间光调制器(SLM) LCOS
2009/8/14
提出一种利用空间光调制器对物方光线进行调制并多次曝光的方法来获取HDR图像.讨论了该方法的原理,并根据原理搭建实验装置进行了实验.实验装置中以LCOS作为空间光调制器,以CMOS作为成像传感器,通过多次曝光获得系列图像,利用图像合成算法生成HDR图像.该方法具有实时性好、扩展性强、成本较低等优点.
一个稳健的用于HDR图像的相机响应函数标定算法
相机响应函数 曝光度 HDR(高动态范围)
2007/11/1
在Mitsunaga和Nayar给出的多项式模型的基础上, 增加了图像亮度为0映射到场景亮度也为0的限制条件，并改进了迭代结束条件，所得到的新的标定算法可以使用多张不同曝光度的图像来标定相机响应函数，不同曝光度可以通过改变相机的光圈大小和曝光时间长短来得到.文中所述算法可以自动估计并最后求得精确的曝光度比, 省略了原有算法需要输入曝光度比估计值的步骤.算法得到了相机响应函数后，可用多张不同曝光度的...
