摘要： In one example in accordance with the present disclosure, a system is described. The system includes a replicator to receive a reference model of an object to be scanned. A capture system simulator of the system simulates capture settings. The capture system includes a number of capture devices placed around the object. The capture system also includes a controller. The controller extracts simulated capture data for the capture system and determines adjustments to the capture settings based on extracted simulated capture data.

摘要： A method of determining a region of interest may include with a first image capturing device, determining a region of interest within a field of view common between the first image capturing device and a second image capturing device, the first image capturing device capturing an image at a lower resolution than the second image capturing device; determining a corner defining the region of interest; and upscaling the determined corner to match a corner within a field of view of an image captured by the second image capturing device.

摘要： An example system includes a pose engine to determine a pose of a camera based on an environmental measurement. The system also includes a transform engine to determine a transform to apply to frames captured by the camera based on the pose of the camera. The system includes a correction engine to apply the transform to the frames captured by the camera in substantially real-time with capturing of the frames.

摘要： 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.

摘要： A device includes a near field communication (NFC) module that stores data and a list of devices authorized to receive the data. A request for the data is received at the NFC module from a second device while the device is operating in a first mode. The data is transferred from the NFC module to the second device using NFC communications protocol based on a determination that the second device is an authorized device.

摘要： A system may include a scanning device to scan a plurality of objects in a controlled environment and in multiple orientations, a scan calibrator to perform calibration of the scanning by the scanning device, and a database configurator. The database configurator may be configured to determine multi-dimensional invariant orientations and geometric properties of features of the scanned objects to generate subsets of objects from the plurality of objects that are unique to the subset of objects, determine correlations between the determined multi-dimensional invariant orientation and the geometric properties of the features, generate group identifiers for each of the subsets of objects, perform supervised training on the determined multi-dimensional invariant orientations and geometric properties to generate trained parameters for each of the subsets of objects, and generate an object database based on the group identifiers and the trained parameters.
