Web1 Introduction. In the calculation of the feature matching described above, the calculation of the camera motion pose estimation through the completed feature matching seems to be very feasible, but it also has many problems: Web我们在OpticalFlowSingleLevel函数中实现了单层光流函数,其中调用了cv:parallel_for_并行调用OpticalFlowTracker::calculateOpticalFlow,该函数计算指定范围内特征点的光流。 这个并行 for循环内部是Intel tbb库实现的,我们只需按照其接口,将函数本体定义出来,然后将函数作为std::function对象传递给它。 具体函数实现中(即 calculateOpticalFlow ),我们 … WebJul 8, 2024 · 在上述代码中我们为 OpticalFlowSingleLevel 函数添加一个 bool inverse 参数,指定要使用正常的算法还是反向的算法。 多层光流. 问题:因为LK光流的结果依赖于图像梯度. 但梯度不够平滑,可能剧烈变化; 局部的梯度不能用于预测长期图像走向; 解决方式:多层光流 pork luncheon meat slices
