The pose is expressed in Computer Vision (CV) convention (x-right, y-down, z-away) as illustrated below.If the pose capability is declared in the driver but poses are not sent, the camera frame will be retained in memory by Vuforia Engine and the device will run out of memory after a few seconds. The pose is in a right-handed (RH) coordinate system. The pose is in the camera coordinate system. The pose represents the position of the camera in the world. As the device already renders from its world coordinate system with low latency, augmentations rendered relative to Vuforia detected objects will exhibit the same visual stability that is provided by the device.NOTE: Vuforia Engine does not currently optimize for moving objects.Integration Details Sending data from your Vuforia DriverTo deliver poses and camera frames to the Vuforia Driver we require that the pose is delivered first immediately followed by the camera frame with both having exactly the same timestamp value (in nanoseconds).When calculating the pose to delivery to the Vuforia Driver you should ensure the following: A Vuforia Driver provides poses and images to the Vuforia Engine which then reports object poses in the device’s world coordinate system.In a Vuforia application for a phone or tablet the ‘Main Camera’ is typically positioned by Vuforia this could be either When poses are provided to Vuforia Engine by a Vuforia Driver this means that poses are reported in the device’s positional device tracker coordinate system.NOTE: That Device Tracker and camera poses reported by Vuforia use the traditional rendering spatial model with x-right, y-up and z-towards as illustrated below:For rendering we assume that the device renders into the positional device tracker coordinate system positioning the scene camera based on the current device position.When using the Vuforia Engine Unity Package with an external device tracker you need to consider how the ‘Main Camera’ will be positioned. Object and Device Tracker poses are reported in world coordinate system.
