Research on Multi-sensor High Dynamic Range Imaging Technology and Application

In dynamic scene imaging, multi-sensor high dynamic range (HDR) fusion technology used to solve the ghosting problem of multi-exposure fusion based on camera aperture, and achieve high-quality HDR video imaging. Therefore, it has made significant progress in image capture and synthesis of HDR optical imaging. First, we introduce the development status of multi-sensor based on time bracketing and space bracketing. Then introduce the different method of multi-exposure image fusion, including aligning different exposures, rejecting misalignment information and patch-based optimization. Finally, discuss the key technical issues and development trends of this technology in HDR imaging technology.
