MovieLife 电影生活

今天看到一个很有意思的项目：https://www.lampysecurity.com/post/the-infinite-audio-book

在这里插入图片描述

“我有一个看似愚蠢的想法。通常，这类想法只是一闪而过，很少会付诸实践。但这次有所不同。假如你的生活是一部电影，它会讲述什么故事？会发生什么？我的想法就是从这里开始的。随着 AI 的兴起，我想看看是否可以让 AI 实时讲述我的生活。我们的设想是让相机拍摄一张照片，生成对照片的描述，然后由 ChatGPT 基于所看到的内容写一个叙事场景，再将文本转换为语音并播放。”

我的实现

在整个项目中，我使用了笔记本的摄像头进行操作，运行在笔记本上，感觉非常有趣。ChatGPT的描述充满了正能量！最初的代码无法运行，因此我参考了https://platform.openai.com/docs/guides/vision，进行了修改，并成功在我的电脑上运行起来。至于树莓派，我了解得不多，正在考虑是否可以在手机上部署，但还没有深入研究。

项目概念

创意起源：作者反思了人生如电影的概念,探索了使用AI实时叙述他的人生。
技术整合：该项目利用了OpenAI的各种服务,包括图像识别、语言模型和文字转语音。

硬件设置

选择设备：一个带有Pi相机和Pi Sugar 3电池的Raspberry Pi Zero,以便携带。
其他要求:
- 带有micro HDMI的显示器,用于配置。
- 鼠标/键盘进行交互。
- USB micro转female A适配器。
- SD卡用于Raspberry Pi OS。
- 由于缺乏音频插孔,需要无线耳机。

设计和3D打印

外壳设计：作者修改了现有的3D外壳设计,以适应电池,并使用Bambu Lab P1S 3D Printer。

软件和API集成

OpenAI API设置:
- 创建账户并生成API密钥。
- 解释API调用成本和使用情况。

代码实现

编程语言：选择Python来编码项目。

分步细节:

配置文件.env

OPENAI_API_KEY="这里填入你的API_KEY"

导入必要的库。

from pathlib import Path
from openai import OpenAI
import requests
import os
import cv2
import base64
import time
import pygame
from dotenv import load_dotenv# 加载 .env 文件
load_dotenv()
# OpenAI API key
client = OpenAI()# OpenAI API Key
api_key = os.getenv("OPENAI_API_KEY")
# Path to your image
image_path = "vision.jpg"# Getting the base64 string
base64_image = "error"headers = {"Content-Type": "application/json","Authorization": f"Bearer {api_key}"
}payload = {"model": "gpt-4o-mini","messages": [{"role": "user","content": [{"type": "text","text": "请描述这张图片?"},{"type": "image_url","image_url": {"url": f"data:image/jpeg;base64,{base64_image}"}}]}],"max_tokens": 300
}

从相机捕获图像。

def capture_webcam_photo(save_directory="webcam_photos"):# Create directory if it doesn't existif not os.path.exists(save_directory):os.makedirs(save_directory)# Open default camera (usually the first camera)cap = cv2.VideoCapture(1)# Capture frame-by-frameret, frame = cap.read()# Generate a unique filenamefilename = os.path.join(save_directory, "webcam_photo.jpg")# Save the captured frame as an imagecv2.imwrite(filename, frame)# Release the capturecap.release()return filename

将图像编码为base64格式,以便提交API。

# Function to encode the image
def encode_image(image_path):with open(image_path, "rb") as image_file:return base64.b64encode(image_file.read()).decode('utf-8')

使用OpenAI的模型根据图像描述生成叙述性响应。

def generate_response(prompt):name = "BoBo"age = "60"location = "体操之乡 湖北仙桃"response = client.chat.completions.create(model="gpt-4o-mini",messages=[{"role": "system","content": "你是一部电影的叙述者，讲述一个名叫 " + name + "。他的年龄  " + age + " ，生活在 " + location + "。当你看到一张场景图片时，你可以从" + name + "的角度描述这张照片，所有人物都用第三人称。 "},{"role": "user", "content": prompt}])return response.choices[0].message.content

将文本响应转换为语音并播放。

def text_to_speech(text):speech_file_path = Path(__file__).parent / "speech.mp3"response = client.audio.speech.create(model="tts-1",voice="alloy",input=text)response.stream_to_file(speech_file_path)return speech_file_pathdef play_mp3(file_path):# Initialize Pygamepygame.init()try:# Initialize the mixerpygame.mixer.init()# Load the MP3 filepygame.mixer.music.load(file_path)# Play the MP3 filepygame.mixer.music.play()# Wait until the music finishes playingwhile pygame.mixer.music.get_busy():pygame.time.Clock().tick(10)  # Adjust the playback speedexcept pygame.error as e:print(f"Error playing MP3: {e}")finally:# Cleanup Pygamepygame.mixer.music.stop()pygame.mixer.quit()pygame.quit()

主函数：

while True:start_time = time.time()saved_path = capture_webcam_photo()base64_image = encode_image(saved_path)# 将图像插入到 payload 中payload["messages"][0]["content"][1]["image_url"]["url"] = "data:image/jpeg;base64," + base64_image# 发送请求response = requests.post("https://api.openai.com/v1/chat/completions", headers=headers, json=payload)# 检查响应状态if response.status_code != 200:print(f"Error: {response.status_code} - {response.text}")continue  # 跳过此次循环，继续尝试jsonZ = response.json()# 检查是否有 'choices' 键if 'choices' in jsonZ and len(jsonZ['choices']) > 0:try:response_text = generate_response(jsonZ["choices"][0]["message"]["content"])output_file = text_to_speech(response_text)  # play_mp3(output_file)  # except KeyError as e:print(f"KeyError: {e}")print("Received response:", jsonZ)continue  # 跳过此循环并记录错误else:print("No choices found in response")# 计算经过的时间elapsed_time = time.time() - start_time# 等待剩余时间remaining_time = max(0, 20 - int(elapsed_time))time.sleep(remaining_time)

主要功能

连续运行：主循环每20秒捕获一次图像,通过OpenAI API进行处理,生成叙述,转换为语音,并播放。
