Abstract: An image display system is disclosed and includes: at least one first projection unit (112), configured to project rays of N images on a first plane, so that the rays of the N images are projected on N first regions of the first plane, where the N images are images of target object photographed based on N angles, and N≥2; and at least one first refraction unit (122), configured on the first plane, and configured to perform refraction processing on the rays of the images projected on the first regions, so that the rays of the N images are collected on a common display region. In this way, presentation of a three-dimensional image can adapt to a human eye viewing habit.

Abstract: A ground environment detection method and apparatus are disclosed, where the method includes: scanning a ground environment by using laser sounding signals having different operating wavelengths, receiving a reflected signal that is reflected back by the ground environment, determining scanning spot information of each scanning spot of the ground environment based on the reflected signal, determining space coordinate information and a laser reflection feature of each scanning spot based on each piece of scanning spot information, partitioning the ground environment into sub-regions having different laser reflection features, and determining a ground environment type of each sub-region. Lasers having different operating wavelengths are used to scan the ground, and the ground environment type is determined based on the reflection intensity of the ground environment under different wavelengths of lasers, thereby improving a perception effect of a complex ground environment, and better determining a passable road surface.

Abstract: In a power factor correction PFC circuit control method and a PFC circuit, a control module determines that an alternating current on a single-phase input/output terminal is in a positive half cycle. The control module turns on or turns off switching transistors on the first bridge arm and the second bridge arm, to boost a first voltage at a first parallel connection point. The control module turns on a switching transistor on the third bridge arm when determining that the first voltage is equal to a voltage of a positive bus of the direct current module. A switching loss of the PFC circuit can be effectively reduced, and performance of the PFC circuit can be improved.

Abstract: This application provides an electrical element, a circuit board, and a switching power supply. The electrical element includes a first magnetic core and a second magnetic core disposed opposite to each other. The first magnetic core and the second magnetic core enclose space for accommodating a winding. The first magnetic core and the second magnetic core are further configured to bind a magnetic induction wire. The electrical element further includes a third magnetic core located in the space enclosed by the first magnetic core and the second magnetic core. The third magnetic core is configured to wind the winding. The third magnetic core is fixedly connected to the first magnetic core and the second magnetic core. An air gap is disposed in at least one of the first magnetic core and/or the second magnetic core.

Abstract: The present disclosure provide a video communication method and system, applied to a scenario of video communication between a first location and a second location, and at least two users at the second location participate in the video communication. The method includes: determining a first user and a second user that are in a call or that are going to have a call with each other; obtaining an eye-to-eye virtual view image of the first user; and displaying the eye-to-eye virtual view image of the first user on a display at the second location in a manner used for corresponding to the second user, so that the eye-to-eye virtual view image of the first user corresponds to the second user.
