写一个gocator2630相机，保存灰度图的c++程序

以下是一个简单的示例程序，可以使用gocator2630相机保存灰度图像：

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <GoSdk/GoSdk.h>
#include <GoSdk/GoSystem.h>
#include <GoSdk/GoSensor.h>
#include <GoSdk/GoUtils.h>

#define FILENAME "image.pgm"

int main(int argc, char **argv)
{
    kStatus status;
    GoSystem system;
    GoSensor sensor;
    GoDataSet dataset;
    GoStamp stamp;
    GoDataMsg dataObj;
    GoSurface surface;
    uint32_t i, row, col;
    uint8_t *buffer;
    FILE *fp;

    // 初始化SDK
    status = GoSdk_Construct();
    if (kSuccess != status)
    {
        printf("GoSdk_Construct Error: %d\n", status);
        return EXIT_FAILURE;
    }

    // 创建系统对象
    status = GoSystem_Construct(&system, kNULL);
    if (kSuccess != status)
    {
        printf("GoSystem_Construct Error: %d\n", status);
        GoSdk_Destruct();
        return EXIT_FAILURE;
    }

    // 连接到传感器
    status = GoSystem_FindSensorByName(&system, "Gocator-2630-0", &sensor);
    if (kSuccess != status)
    {
        printf("GoSystem_FindSensorByName Error: %d\n", status);
        GoSystem_Destroy(&system);
        GoSdk_Destruct();
        return EXIT_FAILURE;
    }

    // 启动传感器
    status = GoSensor_Connect(sensor);
    if (kSuccess != status)
    {
        printf("GoSensor_Connect Error: %d\n", status);
        GoSystem_Destroy(&system);
        GoSdk_Destruct();
        return EXIT_FAILURE;
    }

    // 启动数据采集
    status = GoSystem_EnableData(&system, kTRUE);
    if (kSuccess != status)
    {
        printf("GoSystem_EnableData Error: %d\n", status);
        GoSensor_Disconnect(sensor);
        GoSystem_Destroy(&system);
        GoSdk_Destruct();
        return EXIT_FAILURE;
    }

    // 获取数据集
    status = GoSensor_Capture(sensor);
    if (kSuccess != status)
    {
        printf("GoSensor_Capture Error: %d\n", status);
        GoSystem_DisableData(&system);
        GoSensor_Disconnect(sensor);
        GoSystem_Destroy(&system);
        GoSdk_Destruct();
        return EXIT_FAILURE;
    }

    status = GoSystem_ReadData(&system, &dataset);
    if (kSuccess != status)
    {
        printf("GoSystem_ReadData Error: %d\n", status);
        GoSystem_DisableData(&system);
        GoSensor_Disconnect(sensor);
        GoSystem_Destroy(&system);
        GoSdk_Destruct();
        return EXIT_FAILURE;
    }

    // 获取表面数据
    status = GoDataSet_FindAndExtractData(dataset, GoDataMsgType_Surface, &dataObj);
    if (kSuccess != status)
    {
        printf("GoDataSet_FindAndExtractData Error: %d\n", status);
        GoSystem_DisableData(&system);
        GoSensor_Disconnect(sensor);
        GoSystem_Destroy(&system);
        GoSdk_Destruct();
        return EXIT_FAILURE;
    }

    status = GoSurface_Assemble(dataObj, &surface);
    if (kSuccess != status)
    {
        printf("GoSurface_Assemble Error: %d\n", status);
        GoSystem_DisableData(&system);
        GoSensor_Disconnect(sensor);
        GoSystem_Destroy(&system);
        GoSdk_Destruct();
        return EXIT_FAILURE;
    }

    // 保存灰度图像
    fp = fopen(FILENAME, "wb");
    if (fp == NULL)
    {
        printf("Error: Failed to open file %s\n", FILENAME);
        GoSurface_Destroy(surface);
        GoSystem_DisableData(&system);
        GoSensor_Disconnect(sensor);
        GoSystem_Destroy(&system);
        GoSdk_Destruct();
        return EXIT_FAILURE;
    }

    fprintf(fp, "P5\n%u %u\n255\n", surface->width, surface->length);

    buffer = (uint8_t *)malloc(surface->width * sizeof(uint8_t));
    for (row = 0; row < surface->length; row++)
    {
        for (col = 0; col < surface->width; col++)
        {
            buffer[col] = (uint8_t)(surface->data[row * surface->width + col] / 256);
        }
        fwrite(buffer, sizeof(uint8_t), surface->width, fp);
    }
    free(buffer);

    fclose(fp);

    // 释放资源
    GoSurface_Destroy(surface);
    GoDataSet_Destroy(dataset);
    GoSystem_DisableData(&system);
    GoSensor_Disconnect(sensor);
    GoSystem_Destroy(&system);
    GoSdk_Destruct();

    return EXIT_SUCCESS;
}

这个程序使用GoSDK连接到gocator2630相机，获取表面数据，然后将其保存为灰度图像。保存的图像格式为PGM，可以使用常见的图像处理软件打开。
