Lambda関数でrekognitionを使用する
S3のPutObjectをイベントリソースにしたLambda関数の例。S3にアップロードされた画像を解析します。
import json import urllib import boto3 import os import logging logger = logging.getLogger() logger.setLevel(logging.INFO) s3 = boto3.client('s3') rekognition = boto3.client('rekognition', 'us-east-1') dynamodb = boto3.resource('dynamodb', region_name='ap-northeast-1') table = dynamodb.Table(os.getenv('TABLE_NAME')) def lambda_handler(event, context): bucket = event['Records'][0]['s3']['bucket']['name'] key = urllib.parse.unquote_plus(event['Records'][0]['s3']['object']['key'], 'utf8') obj = s3.get_object(Bucket=bucket, Key=key) body = obj['Body'].read() # 画像内に含まれるlabel(大まかなオブジェクトの意味。(human | text | outdoor | etc ...)) labels = rekognition.detect_labels(Image={'Bytes':body}, MinConfidence=75) # 顔識別 faces = rekognition.detect_faces(Image={'Bytes':body}, Attributes=['ALL']) rekognized_label = {} rekognized_label['Labels'] = labels['Labels'] rekognized_label['FaceDetails'] = faces['FaceDetails'] logging.info(json.dumps(rekognized_label)) return
以下のように簡単に利用することができる。
