Может ли Affectiva подключиться к Kinect v1

У меня есть проект с бесплатной версией распознавания эмоций Affectivahttps://developer.affectiva.com/ на Ubuntu 14.04.
Я пытаюсь использовать Kinect v1 в качестве устройства ввода для Affectiva.
Я использую lsusb, чтобы найти идентификатор kinect v1: Bus 003 Device 009: ID 045e: 02ae Microsoft Corp. Xbox
NUI Camera. Я пытаюсь изменить const int cameraId = 045e: 02ae в affdex-sdk / CameraDetector.h и создать / opencv-webcam-demo.

,но демонстрационная программа не смогла подключиться к kinect v1 при запуске opencv-webcam-demo.
Есть ли способ использовать Kinect v1 в качестве входных данных Affectiva?

Решение

В настоящее время у нас нет SDK, который поддерживает платформу Kinect.
