Class ARCoreCameraDevice

Namespace

easyar

ARCoreCameraDevice implements an ARCore-based camera device, outputting InputFrame (including image, camera parameters, timestamp, 6DOF position information, and tracking status). When using, you need to first use java.lang.System.loadLibrary to load libarcore_sdk_c.so. After creation, you can call start/stop to start and stop collecting video stream data. When the device is no longer needed, you can call close to close it. Do not continue to use it after close. ARCoreCameraDevice outputs InputFrame through inputFrameSource, and the inputFrameSource should be connected to InputFrameSink for use. bufferCapacity indicates the capacity of InputFrame buffer. If there are more InputFrame output from this device than this number and not released, the device will no longer output new InputFrame until the previous InputFrame is released. This may cause problems such as stuck screen. Note: The current implementation of ARCore (v1.13.0) has a memory leak when creating and destroying the session. Multiple creations and destructions will lead to continuous growth of memory usage and will not be released after destruction.

Methods

isAvailable

Check if available. Returns true only on Android system and with ARCore installed. Returns false when libarcore_sdk_c.so is not loaded. Note: If the device does not support ARCore but ARCore's apk is sideloaded, this function will return true, but ARCore cannot be used normally.
