A Research for 3D Visualization by Mobile Phones based on Monocular Images

Abstract

Recently, Mobile phones have been widely spread and used for taking pictures and browsing images. On the other hand, researches about 3D image processing have been developed and lots of 3D contents are widely used now. However, these contents need a special equipment or operations. Therefore, our purpose is taking and browsing 3D images by means of a way close to the current usage of mobile phones with monocular cameras and display. First, we propose a depth estimation method from two consecutive images, where one is taken with flash and another with no flash. We improve the accuracy of depth estimation by noise reduction and intensity difference. In addition, we propose an appropriate display method of 3D images using mobile phones, through subjective evaluation experiments. Then, we make a 3D image system based on our depth estimation and display method.
