    Abstract: A scale and pose estimation method for a camera system is disclosed. Camera data for a scene acquired by the camera system is received. A rotation prior parameter characterizing a gravity direction is received. A scale prior parameter characterizing scale of the camera system is received. A cost of a cost function is calculated for a similarity transformation that is configured to encode a scale and pose of the camera system. The cost of the cost function is influenced by the rotation prior parameter and the scale prior parameter. A solved similarity transformation is determined upon calculating a cost for the cost function that is less than a threshold cost. An estimated scale and pose of the camera system is output based on the solved similarity transformation.

    Abstract: One example provides a computing device configured to capture, via the camera, first image data imaging a first physical world location, create a first spatial representation of the first physical world location based on the first image data, receive a user input defining a pose of a first virtual spatial anchor point relative to a feature imaged in the first image data, track user movement to a second physical world location, capture second image data imaging the second physical world location, receive a user input defining a pose of a second virtual spatial anchor point relative to a feature imaged in the second image data, and send, to a remote computing device, data representing the first spatial representation, the pose of first spatial anchor point, the second spatial representation, the pose of second spatial anchor point, and a positional relationship between first and second spatial anchor points.
