基于c++实现可见光与红外图像的融合的代码

以下是使用C语言实现可见光与红外图像融合的代码示例：

#include <stdio.h>
#include <stdlib.h>
#include <string.h>

#define WIDTH 640   //图像宽度
#define HEIGHT 480  //图像高度

//加载可见光图像
void loadRGBImage(const char* filename, unsigned char* R, unsigned char* G, unsigned char* B)
{
    FILE* fp = fopen(filename, "rb");
    if (!fp)
    {
        printf("Failed to open file %s\n", filename);
        exit(1);
    }

    fseek(fp, 54, SEEK_SET); //跳过文件头

    for (int i = 0; i < HEIGHT; i++)
    {
        for (int j = 0; j < WIDTH; j++)
        {
            B[(HEIGHT - i - 1) * WIDTH + j] = fgetc(fp);
            G[(HEIGHT - i - 1) * WIDTH + j] = fgetc(fp);
            R[(HEIGHT - i - 1) * WIDTH + j] = fgetc(fp);
        }
    }

    fclose(fp);
}

//加载红外图像
void loadIRImage(const char* filename, unsigned char* IR)
{
    FILE* fp = fopen(filename, "rb");
    if (!fp)
    {
        printf("Failed to open file %s\n", filename);
        exit(1);
    }

    fseek(fp, 512, SEEK_SET); //跳过文件头

    for (int i = 0; i < HEIGHT; i++)
    {
        for (int j = 0; j < WIDTH; j++)
        {
            IR[(HEIGHT - i - 1) * WIDTH + j] = fgetc(fp);
        }
    }

    fclose(fp);
}

//可见光与红外图像融合
void fuseImages(unsigned char* R, unsigned char* G, unsigned char* B, unsigned char* IR, unsigned char* output)
{
    for (int i = 0; i < WIDTH * HEIGHT; i++)
    {
        output[i] = 0.3 * R[i] + 0.59 * G[i] + 0.11 * B[i] + 0.4 * IR[i];
    }
}

int main(int argc, char** argv)
{
    if (argc < 4)
    {
        printf("Usage: %s RGB_image IR_image output_image\n", argv[0]);
        exit(1);
    }

    const char* rgbFilename = argv[1];
    const char* irFilename = argv[2];
    const char* outputFilename = argv[3];

    unsigned char R[WIDTH * HEIGHT];
    unsigned char G[WIDTH * HEIGHT];
    unsigned char B[WIDTH * HEIGHT];
    unsigned char IR[WIDTH * HEIGHT];
    unsigned char output[WIDTH * HEIGHT];

    loadRGBImage(rgbFilename, R, G, B);
    loadIRImage(irFilename, IR);
    fuseImages(R, G, B, IR, output);

    FILE* fp = fopen(outputFilename, "wb");
    if (!fp)
    {
        printf("Failed to open file %s\n", outputFilename);
        exit(1);
    }

    //写文件头
    unsigned char header[54] = { 0x42, 0x4d, 0x36, 0x00, 0x0c, 0x01, 0x00, 0x00, 0x
