Abstract |
Stereo vision has many applications, including 3D movies and the recent advanced driver assisted systems (ADAS). In stereo vision, stereo matching of generating depth information is the most critical technique. In general, there are two categories of stereo matching methods: global and local. Local stereo matching methods are fast due to less computation while global methods can generate more accurate depth information at the cost of more computation complexity. This thesis uses local stereo matching methods with mean filtering and guided image filtering to improve the quality of depth information. A generic local stereo matching method can be divided into four stages: matching cost computation, cost aggregation, disparity selection, and disparity refinement. Guided image filtering can be applied to cost aggregation or disparity refinement. This thesis will study the impacts of using guided image filtering in different stereo matching stages. In hardware implementation for involved mean filtering, instead of the conventional integral image method, we use the moving-sum method with different data reading schemes of with line-based or stripe-based and compare the hardware resource requirement of internal memory buffers |
