This specification generally discloses technology for tracking vehicle positions in a warehouse environment. A system receives stereoscopic image data from a camera on a forklift, in some implementations. The system recognizes an object that is represented in the stereoscopic image data, identifies a representation of the recognized object in a spatial model that identifies, for each of a plurality of objects in an environment, a corresponding location of the object in the environment, determines the location of the recognized object in the environment, determines a relative position between the forklift and the recognized object, based on a portion of the received stereoscopic image data that represents the recognized object, and determines a location of the forklift in the environment, based on the determined location of the recognized object in the environment, and the determined relative position between the forklift and the recognized object.

An electronic apparatus includes a step of controlling first processing for setting a tracking start position at a tracking position immediately before and second processing for setting the tracking start position at a predetermined tracking start position. The electronic apparatus switches and performs the first processing and the second processing depending on a state when the tracking is stopped.

An imaging device includes: an imaging element including a plurality of photoelectric conversion elements arranged in a matrix, and configured to be driven in units of a plurality of lines each including a plurality of photoelectric conversion elements arranged in one direction; a memory; and a processor. The processor is configured to execute detecting an occurrence of a flicker, based on image data generated by the imaging element; and increasing a number of times of exposures in one-frame period of the photoelectric conversion elements included in a line in which the flicker is detected by the detecting, compared with a number of times of exposures in the one-frame period of the photoelectric conversion elements included in a line in which a flicker is not detected.

An electronic device, a method and a computer program product for selecting an active camera from among a front facing camera and at least one rear facing camera. The method includes capturing, via a front facing camera, an image stream containing a face of a user and determining, via a processor, an eye gaze direction of the user based on an image retrieved from the image stream. The eye gaze direction corresponds to a location where the user is looking. The method further includes in response to determining that the user is looking away from a front surface of an electronic device and towards a direction within a field of view of the at least one rear facing camera, selecting, as an active camera, a corresponding one of the at least one rear facing cameras with a field of view containing the location to which the user is looking.

Various embodiments of the present disclosure provide a method for forming a recessed gate electrode that has high thickness uniformity. A gate dielectric layer is deposited lining a recess, and a multilayer film is deposited lining the recess over the gate dielectric layer. The multilayer film comprises a gate electrode layer, a first sacrificial layer over the gate dielectric layer, and a second sacrificial layer over the first sacrificial dielectric layer. A planarization is performed into the second sacrificial layer and stops on the first sacrificial layer. A first etch is performed into the first and second sacrificial layers to remove the first sacrificial layer at sides of the recess. A second etch is performed into the gate electrode layer using the first sacrificial layer as a mask to form the recessed gate electrode. A third etch is performed to remove the first sacrificial layer after the second etch.

Systems, apparatuses, and methods are described which provide a camera mount system. A camera mount is in communication with a positioning device. The positioning device has a compass, gyroscope, and emits an infrared light beam. The camera mount has a sensor that receives reflected and/or scattered infrared light from a moving target. The camera mount changes its orientation based on information from its sensor, and gyroscope and compass information from the positioning device.

There is provided a method and apparatus for tracking eyes of a user. The method and apparatus may acquire an image of the user, acquire an illuminance of a viewpoint from which the image is captured, and output coordinates of the eyes tracked from the image by operating at least one of a high illuminance eye tracker that operates at a high illuminance or a low illuminance eye tracker that operates at a low illuminance based on the acquired illuminance.
