Abstract: A method and device for adjusting a position of an earphone, equipment and storage medium are disclosed. The earphone is provided with a TOF sensor. The method comprises: acquiring position information of an ear using the TOF sensor, wherein the position information of the ear includes positions of points describing the ear in morphology; determining a position of a center point of an ear canal of the ear according to the position information of the ear; acquiring a position of a center point of the earphone; and outputting an adjustment vector of the position of the earphone according to the position of the center point of the ear canal and the position of the center point of the earphone.

Abstract: Embodiments of this application provide a load balance method and an apparatus thereof. The method may include the following steps: receiving, by a load balance node, a first service request packet from a service request end, where the first service request packet includes address information of the service request end, address information of a to-be-processed load balance instance, and a MAC address of the load balance node; determining a to-be-processed service member based on the address information of the to-be-processed load balance instance, where the to-be-processed service member is configured to process the first service request packet; and modifying the MAC address of the load balance node in the first service request packet to a MAC address of the to-be-processed service member, to obtain a second service request packet, and sending the second service request packet to a computing node to which the to-be-processed service member belongs.

Abstract: A projection image automatic correction method and system based on binocular vision. The method includes: acquiring a depth map of a projection image on a projection plane; calculating a first transformation relationship between a source image and the projection image; acquiring a distortion image according to the depth map; acquiring a correction image after correcting the distortion image; calculating a second transformation relationship between the distortion image and the correction image; acquiring a correction relationship between the source image and the correction image according to the first transformation relationship and the second transformation relationship; and correcting the projection image according to the correction relationship. This disclosure is configured to realize the efficient automatic correction of the projection image without being limited by the projection area, and the correction flexibility is high.

Abstract: The present disclosure discloses a virtual reality (VR) helmet and a method for using same. The virtual reality helmet has two optional playing modes: playing a VR video stored in the storage module, or playing a VR video inputted by the video input device when it is detected that the video input device is connected. Therefore, the VR helmet does not only have the function of inputting a video in a wired way in traditional helmets, but also can play a video which is stored in advance locally, so the user can move around freely without the limitation of the wired input when a local video is played. In a preferred embodiment, the VR helmet, by having a proximity sensor used to monitor the wearing state of the user, enters a standby mode and turns off the display module to reduce the power consumption of the helmet when it is detected that the user takes off the helmet, and exits the low power consumption standby mode and turns on the display module when it is detected that the user is wearing the helmet.
