Matlab中用于interp2的类似OpenCV Api [英] Similar OpenCV Api for interp2 in Matlab

问题描述

是否有任何与

interp2(x, y, frame(:,:,z), xd, yd, '*linear', 0)

在OpenCV中?

推荐答案

函数cv::remap()几乎满足您的要求，请参见文档

The function cv::remap() does almost what you're asking for, see the documentation here.

您需要预先计算文档中名为map1和map2的输入数组中点的(x，y)目标坐标(如果打包(x，y)坐标，则仅使用一个，否则两个). 等同于'*linear'的OpenCV是cv::INTER_BILINEAR.

You need to precompute the (x,y) target coordinates of the points in the input array(s) called map1 and map2 in the doc (use only one if you pack (x,y) coordinate, two otherwise). The OpenCV equivalent to '*linear' is cv::INTER_BILINEAR.
