“数据维度必须一致”错误

发布于 2024-11-07 10:27:57 字数 439 浏览 0 评论 0原文

im = im2double(imread('rice.png'));

[X Y]= meshgrid(1:size(im,1),1:size(im,2));

surf(zeros(size(im)),X,Y,im,'EdgeColor','none');

当我运行这个脚本时，它工作得很好，但是当我尝试将图像更改为 RGB 图像时，它给了我这 2 个错误，

??? Error using ==> surf at 78 Data dimensions must agree.

Error in ==> CoOrdinating at 6 surf(zeros(size(im)),X,Y,im,'EdgeColor','none');

我尝试将图像转换为灰度，但它对我不起作用，并给了我相同的错误

任何帮助？

surf(zeros(size(im)),X,Y,im,'EdgeColor','none');

when i run this script it worked me fine but when i tried to change the image to RGB image it gives me this 2 errors

??? Error using ==> surf at 78 Data dimensions must agree.

Error in ==> CoOrdinating at 6 surf(zeros(size(im)),X,Y,im,'EdgeColor','none');

i tried to convert the image to grayscale but it didn't work with me and gave me the same errors

any help ?

我有一种有趣的感觉，你忘记将灰度图像传递给其余的函数，因为我在第一次尝试运行此代码时也这样做了：P

im = im2double(imread('rice.png'));

if (isrgb (im))
    im2 = rgb2gray (im);
else
    im2 = im;
end

[X Y] = meshgrid (1:size(im2,1), 1:size(im2,2));
surf(zeros (size(im2)),X,Y,im2,'EdgeColor','none')

这对我有用（使用 RGB 图像和灰度图像）

I have a funny feeling you forgot to pass the grayscale image to the rest of the functions, because I also did it in my first attempt to run this code :P

im = im2double(imread('rice.png'));

if (isrgb (im))
    im2 = rgb2gray (im);
else
    im2 = im;
end

[X Y] = meshgrid (1:size(im2,1), 1:size(im2,2));
surf(zeros (size(im2)),X,Y,im2,'EdgeColor','none')

This worked for me (with an rgb image and a grayscale image)
