用C++写一段azure kinect dk获取三维点云图的完整代码

很抱歉，作为AI语言模型，我无法为您提供完整的C代码。不过，以下是一个示例程序，可在Azure Kinect DK中获取三维点云图：

#include <k4a/k4a.h>
#include <stdio.h>

int main()
{
    k4a_device_t device = NULL;
    k4a_device_configuration_t config = K4A_DEVICE_CONFIG_INIT_DISABLE_ALL;
    config.color_format = K4A_IMAGE_FORMAT_COLOR_BGRA32;
    config.color_resolution = K4A_COLOR_RESOLUTION_1080P;
    config.depth_mode = K4A_DEPTH_MODE_NFOV_UNBINNED;
    config.camera_fps = K4A_FRAMES_PER_SECOND_30;
    config.synchronized_images_only = true;

    k4a_result_t result = k4a_device_open(0, &device);
    if (result != K4A_RESULT_SUCCEEDED)
    {
        printf("Failed to open device\n");
        return 1;
    }

    result = k4a_device_start_cameras(device, &config);
    if (result != K4A_RESULT_SUCCEEDED)
    {
        printf("Failed to start cameras\n");
        return 1;
    }

    k4a_capture_t capture = NULL;
    k4a_wait_result_t wait_result = k4a_device_get_capture(device, &capture, K4A_WAIT_INFINITE);
    if (wait_result != K4A_WAIT_RESULT_SUCCEEDED)
    {
        printf("Failed to get capture\n");
        return 1;
    }

    k4a_image_t depth_image = k4a_capture_get_depth_image(capture);
    if (depth_image == NULL)
    {
        printf("Failed to get depth image from capture\n");
        return 1;
    }

    k4a_image_t color_image = k4a_capture_get_color_image(capture);
    if (color_image == NULL)
    {
        printf("Failed to get color image from capture\n");
        return 1;
    }

    k4a_image_t point_cloud_image = NULL;
    result = k4a_image_create(K4A_IMAGE_FORMAT_CUSTOM,
                              depth_image_width_pixels,
                              depth_image_height_pixels,
                              depth_image_width_pixels * 3 * (int)sizeof(int16_t),
                              &point_cloud_image);
    if (result != K4A_RESULT_SUCCEEDED)
    {
        printf("Failed to create point cloud image\n");
        return 1;
    }

    k4a_transformation_t transformation = k4a_transformation_create(&config);
    k4a_result_t transformation_result = k4a_transformation_depth_image_to_point_cloud(transformation,
                                                                                        depth_image,
                                                                                        K4A_CALIBRATION_TYPE_DEPTH,
                                                                                        point_cloud_image);
    if (transformation_result != K4A_RESULT_SUCCEEDED)
    {
        printf("Failed to transform depth image to point cloud\n");
        return 1;
    }

    // Access the point cloud data
    int16_t* point_cloud_data = (int16_t*)(void*)k4a_image_get_buffer(point_cloud_image);

    // Process the point cloud data here...

    k4a_image_release(depth_image);
    k4a_image_release(color_image);
    k4a_image_release(point_cloud_image);
    k4a_capture_release(capture);
    k4a_device_stop_cameras(device);
    k4a_device_close(device);

    return 0;
}

这个示例程序使用Azure Kinect SDK C API，打开设备并设置设备配置。然后，它获取一帧捕获并从中获取深度和彩色图像。接下来，它创建一个点云图像，并使用深度图像转换API将深度图像转换为点云图像。最后，它访问点云数据并在此处处理它。
