双目测距代码matlab

以下是一个简单的双目测距代码示例，使用MATLAB编写。该代码需要两个已经校准好并且已经拍摄了左右两张图像的相机。

% 双目测距代码
% 假设已经校准好了两个相机

% 读取左右两张图像
left_image = imread('left_image.jpg');
right_image = imread('right_image.jpg');

% 定义区域大小和搜索范围
win_size = 5;
search_range = 50;

% 设置视差范围
min_disp = 0;
max_disp = 64;

% 计算视差图
disp_map = zeros(size(left_image));
for i = 1:size(left_image, 1)
    for j = 1:size(left_image, 2)
        best_offset = 0;
        min_diff = 255^2;
        
        % 在搜索范围内查找最佳匹配
        for offset = min_disp:max_disp
            if (j-offset < 1)
                continue;
            end
            left_patch = left_image(i-win_size:i+win_size, j-win_size:j+win_size);
            right_patch = right_image(i-win_size:i+win_size, j-offset-win_size:j-offset+win_size);
            diff = sum(sum((left_patch - right_patch).^2));
            if diff < min_diff
                min_diff = diff;
                best_offset = offset;
            end
        end
        disp_map(i, j) = best_offset;
    end
end

% 计算深度图
baseline = 50;  % 相机基线长度
focal_length = 100;  % 焦距
depth_map = focal_length * baseline ./ disp_map;

% 显示深度图
imshow(depth_map, []);
