摘要： Generating a 3D model may include determining, based on sensor data from a touch sensor on a first device, a touch event, wherein the touch event comprises a touch on the first device by a touching object. Generating a 3D model may also include, in response to a touch event, obtaining a first image of the touching object by a first camera of the first device, and obtaining, from a second device, a second image of the touching object, wherein the first image of the touching object captures a first view of the touching object, and wherein the second image of the touching object captures a second view of the touching object. A model of the touching object is generated based on the first image and the second image.

摘要： The present disclosure relates generally to remote touch detection. In some examples, a first electronic device obtains first image data and second image data about an input, and performs an operation based on the input in accordance with a determination that a set of one or more criteria is met based on the first image data and the second image data. In some examples, a first electronic device causes emission of infrared light by an infrared source of a second electronic device, obtains image data about an input, and performs an operation based on the input in accordance with a determination that a set of one or more criteria is met based on the image data.

摘要： In one implementation, a device has a processor, a projector, a first infrared (IR) sensor, a second IR sensor, and instructions stored on a computer-readable medium that are executed by the processor to estimate the sensor-to-sensor extrinsic parameters. The projector projects IR pattern elements onto an environment surface. The first sensor captures a first image including first IR pattern elements corresponding to the projected IR pattern elements and the device estimates 3D positions for first IR pattern elements. The second IR sensor captures a second image including second IR pattern elements corresponding to the projected IR pattern elements and the device matches the first IR pattern elements and the second IR pattern elements. Based on this matching, the device estimates a second extrinsic parameter corresponding to a spatial relationship between the first IR sensor and the second IR sensor.

摘要： Systems, methods, and computer readable media to categorize a pixel (or other element) in an image into one of a number of different categories are described. In general, techniques are disclosed for using properties (e.g., statistics) of the regions being categorized to determine the appropriate size of window around a target pixel (element) and, when necessary, the manner in which the window may be changed if the current size is inappropriate. More particularly, adaptive window size selection techniques are disclosed for use when categorizing an image's pixels into one of two categories (e.g., black or white). Statistics of the selected region may be cascaded to determine whether the current evaluation window is acceptable and, if it is not, an appropriate factor by which to change the currently selected window's size

摘要： Three dimensional model construction includes obtaining a first image of an object captured by a first camera facing a first direction, obtaining a second image of the object captured by a second camera facing a second direction, wherein the second camera captures the second image of the object as a reflection in a mirror, determining a virtual baseline distance between the first camera and a device including the second camera based on a location of the first camera, a known spatial relationship between the first camera and the device, and a reflected distance of the second camera, and generating at least a partial 3D model of the first object using the first image, the second image, and the virtual baseline distance.
