Abstract: An example system includes a camera aimable at a planar platform, a depth sensor aimable at the planar platform, and a controller to control the camera to obtain a captured image of the planar platform. The controller is further to control the depth sensor to capture depth data of the planar platform. The controller is further to determine a pose of the camera using the depth data and features extracted from the captured image.

Abstract: An example system includes a plurality of cameras to capture images of a target object and a controller to connect to the plurality of cameras. The controller is to control the plurality of cameras to capture the images of the target object. The controller is further to determine a pose of a camera of the plurality of cameras. The system further includes a platform to support the target object. The platform includes a plurality of unique markers arranged in a predetermined layout. The controller is further to determine the pose of the camera based on unique markers of the plurality of unique markers that are detected in an image captured by the camera.
