소개

HUAWEI AR Engine tiene soporte para detectar objetos en el mundo real que se llama "Seguimiento del entorno"y con él puede registrar iluminación, plano, imagen, objeto, superficie y otra información ambiental para ayudar a sus aplicaciones a fusionar objetos virtuales en escenarios físicos . 문도.

신체 추적

Esta función identifica y rastrea ubicaciones 2D para 23 puntos del esqueleto corporal (o ubicaciones 3D de 15 puntos del esqueleto corporal) y entere el seguimiento de una o dos personas a la vez.
AR Engine reconoce cuerpos humanos y genera coordenadas 2D y 3D (basadas en SLAM) de puntos del esqueleto, y es capaz de cambiar entre las camaras delantera y trasera.
La capacidad de seguimiento del cuerpo le permite superponer objetos virtuales en el cuerpo con un alto grado de precision, como en el hombro izquierdo o el tobillo derecho. 현실화할 수 있는 시장은 자신의 아바타에 정확하게 접근할 수 있으며, AR은 다양한 기능을 사용할 수 있습니다.

Android의 응용 프로그램 예

Para este ejemplo, trabajaremos en el seguimiento del entorno para que podamos detector una mano e interactuar con ella.

HUAWEI AR 엔진 SDK 통합

Antes del desarrollo, integre HUAWEI AR Engine SDK a través del repositorio de Maven en su entorno de desarrollo.
Abra el archivo build.gradle en el directorio raíz de su proyecto de Android Studio.

// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {

AR Engine no es para todos los dispositivos, por lo que primero debemos validar si el dispositivo es compatible con AR Engine y está disponible, aquí está la lista de dispositivos compatibles


Utilizará estos métodos para comprobar si un dispositivo es compatible:
