向量构造函数和Mat

Vector Constructor and Mat

本文关键字：Mat 构造函数向量更新时间：2023-10-16

如何将3元素向量构造器乘以OpenCV中的Mat ?我尝试了以下操作，但它抛出了一个错误:

cv::multiply(src, cv::Vec<_Tp, 3>(2.0, 1.0, 1.0), src);

给出如下错误:

OpenCV Error: Assertion failed (src2.type() == CV_64F && (src2.rows == 4 || src2.rows == 1)) in arithm_op, file /Users/abhishek/Documents/OpenCV-2.4.3/modules/core/src/arithm.cpp, line 1275
libc++abi.dylib: terminate called throwing an exception

你试过了吗:

cv::multiply(src, cv::Scalar(2.0, 1.0, 1.0), src);
