Abstract: A method for obtaining a binocular panoramic image is performed at an electronic apparatus, including: obtaining first and second panoramic images acquired by two panoramic cameras; obtaining at least one group of a first pixel located in the first panoramic image and a second pixel located in the second panoramic image; calculating a distance between the first pixel and the second pixel in each group, and obtaining depth information corresponding to the two panoramic image according to the distance between the first pixel and the second pixel; converting the first panoramic image and the second panoramic image into a first monocular panoramic image and a second monocular panoramic image, respectively in accordance with the corresponding depth information and a preset pupil distance between a first eye and a second eye; and combining a display of the first monocular panoramic image and the second monocular panoramic image in corresponding display regions.

Abstract: A tracking integration method includes acquiring at least one generalized object, extracting position characteristics of the generalized object and establishing the extracted position characteristics as a standard position model, receiving and storing tracking information of the at least one generalized object to complete integration of the tracking information, and querying and displaying the tracking information of the generalized object. The generalized object includes one or more of a person, an item, a digital asset, and a virtual object.

Abstract: A tumor positioning method includes obtaining projection images of a tumor at different angles; and registering the projection images with an initial reference image to obtain a first offset. If it is determined that a virtual reacquisition operation needs to be performed according to the first offset, the method further includes generating a first reference image according to the first offset; and registering the projection images with the first reference image to obtain a second offset. If it is determined that the operation does not need to be performed according to the second offset, the method further includes outputting a first accumulated offset being a sum of the first and second offsets. The method may solve problems of long time consuming and the service life of a treatment couch and acquisition devices being reduced due to repeatedly moving the treatment couch and repeatedly acquiring the X-ray projection images.

Abstract: A speaker comprises a housing, a transducer residing inside the housing, and at least one sound guiding hole located on the housing. The transducer generates vibrations. The vibrations produce a sound wave inside the housing and cause a leaked sound wave spreading outside the housing from a portion of the housing. The at least one sound guiding hole guides the sound wave inside the housing through the at least one sound guiding hole to an outside of the housing. The guided sound wave interferes with the leaked sound wave in a target region. The interference at a specific frequency relates to a distance between the at least one sound guiding hole and the portion of the housing.

Abstract: Disclosed is an interactive device for an internet radio station, comprising a content presentation unit and a content selection unit. The content selection unit includes a knob, a selection module, a processing module, an indication module and a communication module. The knob inputs by a user, a channel selection instruction by means of manual rotation; the selection module generates a corresponding electrical signal according to the channel selection instruction; the processing module obtains, according to the electrical signal, a corresponding audio resource from the network radio station and releases the audio resource to the content presentation unit which plays the audio resource. The indication module generates, under the driving of the knob, a state change corresponding to the channel selection instruction. In this way, the user can select the audio resource by rotating the knob, so that the channel selection manner is similar to the traditional radio rotary tuning method.
