Abstract	本申请提供了一种低功耗立体匹配系统及获取深度信息的方法，该系统包括依次连接的普查模块、分区优化模块、多路径代价聚合模块以及深度计算模块。本申请通过使用Census算法作为初始像素代价值计算函数，并在Census普查模块与多路径代价聚合模块之间加入分区优化模块简化初始像素代价值，基于分区域处理以及最优视差位置，在不影响精度的情况下减少传入多路径代价聚合模块的初始像素代价值数量，进而降低算法耗时以及资源消耗，并确保精度。
Other Abstract	The invention provides a low-power-consumption stereo matching system and a method for acquiring depth information. The system comprises a general survey module, a partition optimization module, a multi-path cost aggregation module and a depth calculation module which are connected in sequence. According to the method, a Census algorithm is used as an initial pixel cost value calculation function,a partition optimization module is added between a Census general survey module and a multi-path cost aggregation module to simplify the initial pixel cost value, and on the basis of partition processing and the optimal parallax position, under the condition that the precision is not influenced, the number of initial pixel cost values transmitted into the multipath cost aggregation module is reduced, so that the algorithm time consumption and the resource consumption are reduced, and the precision is ensured.
