Low Luminance Measurement Based on Binocular Ranging
Chen Zhao, Zhangrong Zhao, Wenzhuo Chen · 2018
In order to realize long-distance and high-precision binocular measurement in low luminance environment, this paper gives a new method which is based on binocular parallax principle and triangulation reconstruction theory, by constructing a portable low luminance prototype system using a stable and efficacious feature extraction method adaptive for low luminance image. Moreover it implements an accurate and optimizational method for the whole system. In the end, the experiment data show that the method is highly robust and precise, and the relative error of the corrected results could be reduced to around 0.1% with twice error compensation.
