Mendeteksi alat pelindung diri dalam citra - Amazon Rekognition

Untuk mendeteksi Alat Pelindung Diri (APD) pada orang dalam citra, gunakan operasi API non-penyimpanan DetectProtectiveEquipment.

Anda dapat memberikan citra input sebagai array bit citra (bit citra yang dikodekan base64) atau sebagai objek Amazon S3, dengan menggunakan AWS SDK atau AWS Command Line Interface (AWS CLI). Contoh-contoh ini menggunakan citra yang tersimpan di bucket Amazon S3. Untuk informasi selengkapnya, lihat Bekerja dengan citra.

Untuk mendeteksi APD pada orang dalam citra

Jika belum:
1. Buat atau perbarui pengguna dengan AmazonRekognitionFullAccess dan AmazonS3ReadOnlyAccess izin. Untuk informasi selengkapnya, lihat Langkah 1: Siapkan akun AWS dan buat Pengguna.
2. Instal dan konfigurasikan AWS CLI dan AWS SDKs. Untuk informasi selengkapnya, lihat Langkah 2: Mengatur AWS CLI dan AWS SDKs.
Unggah citra (yang berisi satu atau beberapa orang yang memakai APD) ke bucket S3 Anda.

Untuk petunjuk, lihat Mengunggah Objek ke Amazon S3 di Panduan Pengguna Layanan Penyimpanan Sederhana Amazon.

Gunakan contoh berikut untuk memanggil operasi DetectProtectiveEquipment. Untuk informasi tentang menampilkan kotak pembatas di citra, lihat Menampilkan kotak pembatas.

Java

Contoh ini menampilkan informasi tentang item APD yang terdeteksi pada orang yang terdeteksi dalam citra.

Ubah nilai amzn-s3-demo-bucket menjadi nama bucket Amazon S3 yang berisi citra Anda. Ubah nilai photo ke nama file citra Anda.
