下面是一个简单的C语言实现的TCP服务器和客户端示例，服务端会监听来自客户端的连接请求，而客户端将按顺序发送图片文件（例如：1.jpg、2.jpg等）到服务器。

服务器代码（server.c）

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <unistd.h>
#include <arpa/inet.h>

#define PORT 8087
#define MAXDATASIZE 1024

int main() {
    int server_sockfd, client_sockfd;
    struct sockaddr_in server_addr, client_addr;
    socklen_t addr_size;
    char buffer[MAXDATASIZE];
    int bytes_received;

    // 创建套接字
    server_sockfd = socket(AF_INET, SOCK_STREAM, 0);
    if (server_sockfd < 0) {
        perror("Socket creation failed");
        exit(EXIT_FAILURE);
    }

    // 设置服务器地址
    server_addr.sin_family = AF_INET;
    server_addr.sin_addr.s_addr = INADDR_ANY;
    server_addr.sin_port = htons(PORT);

    // 绑定套接字
    if (bind(server_sockfd, (struct sockaddr*)&server_addr, sizeof(server_addr)) < 0) {
        perror("Bind failed");
        close(server_sockfd);
        exit(EXIT_FAILURE);
    }

    // 监听
    if (listen(server_sockfd, 5) < 0) {
        perror("Listen failed");
        close(server_sockfd);
        exit(EXIT_FAILURE);
    }

    printf("Server listening on port %d...\n", PORT);

    addr_size = sizeof(client_addr);
    client_sockfd = accept(server_sockfd, (struct sockaddr*)&client_addr, &addr_size);
    if (client_sockfd < 0) {
        perror("Accept failed");
        close(server_sockfd);
        exit(EXIT_FAILURE);
    }

    printf("Client connected.\n");

    while (1) {
        // 接收数据
        bytes_received = recv(client_sockfd, buffer, MAXDATASIZE, 0);
        if (bytes_received <= 0) {
            printf("Client disconnected.\n");
            break;
        }

        // 写入文件
        FILE *fp = fopen("received_image.jpg", "wb");
        if (fp == NULL) {
            perror("File open failed");
            break;
        }
        fwrite(buffer, sizeof(char), bytes_received, fp);
        fclose(fp);

        printf("Received %d bytes, saved to received_image.jpg\n", bytes_received);
    }

    close(client_sockfd);
    close(server_sockfd);
    return 0;
}

客户端代码（client.c）

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <unistd.h>
#include <arpa/inet.h>

#define PORT 8087
#define MAXDATASIZE 1024
#define FILE_PATH "path/to/your/images/" // 替换为实际路径

int main() {
    int sockfd;
    struct sockaddr_in server_addr;
    char buffer[MAXDATASIZE];
    int file_num = 1;

    // 创建套接字
    sockfd = socket(AF_INET, SOCK_STREAM, 0);
    if (sockfd < 0) {
        perror("Socket creation failed");
        exit(EXIT_FAILURE);
    }

    // 设置服务器地址
    server_addr.sin_family = AF_INET;
    server_addr.sin_port = htons(PORT);
    server_addr.sin_addr.s_addr = inet_addr("127.0.0.1"); // 服务器地址，localhost

    // 连接到服务器
    if (connect(sockfd, (struct sockaddr*)&server_addr, sizeof(server_addr)) < 0) {
        perror("Connection failed");
        close(sockfd);
        exit(EXIT_FAILURE);
    }

    while (1) {
        char filename[256];
        snprintf(filename, sizeof(filename), "%s%d.jpg", FILE_PATH, file_num); // 生成文件名

        FILE *fp = fopen(filename, "rb");
        if (fp == NULL) {
            printf("No more files to send. Exiting...\n");
            break;
        }

        // 读取文件内容并发送
        size_t bytes_read = fread(buffer, sizeof(char), MAXDATASIZE, fp);
        while (bytes_read > 0) {
            send(sockfd, buffer, bytes_read, 0);
            bytes_read = fread(buffer, sizeof(char), MAXDATASIZE, fp);
        }
        fclose(fp);

        printf("Sent: %s\n", filename);
        file_num++;
        sleep(1); // 可根据需要调整发送间隔
    }

    close(sockfd);
    return 0;
}

文件路径：在客户端代码中，将 FILE_PATH 替换为你存储图片的实际文件夹路径。

编译代码：使用以下命令编译代码：

gcc -o server server.c
gcc -o client client.c

// capture_images.c
#include <stdio.h>
#include <stdlib.h>

// 传输函数声明
void send_image(const char *filename);

// 图像采集逻辑
int main() {
    // 你的图像采集逻辑
    for (int i = 1; i <= 10; i++) {
        // 假设保存的文件名是 "i.jpg"
        char filename[256];
        snprintf(filename, sizeof(filename), "%d.jpg", i);
        
        // 采集并保存图像的代码
        
        // 发送图像
        send_image(filename);
    }

    return 0;
}

// 发送图像的函数实现
void send_image(const char *filename) {
    // 这里调用你的客户端传输代码，类似于之前提供的 client.c 代码
}
