Abstract: This application provide an image processing method, and relate to the field of computer vision technologies, to perform repair processing on a color image in a fog/haze/smoke extreme weather condition. The image processing method includes: obtaining a first depth map and a color image, where the first depth map and the color image are images respectively shot by a depth sensor and a camera for a same scene; determining an atmospheric light value; performing depth completion on the first depth map to obtain a second depth map, and determining a transmittance based on the second depth map; and performing repair processing on the color image based on the atmospheric light value and the transmittance. The second depth map is used to determine the transmittance, and therefore, a transmittance of higher precision is obtained, thereby improving an image processing effect.

Abstract: This application discloses a signal transmission method, related devices, and a system. The method includes: sending, by a terminal, link reconfiguration request information to a network device at a moment n, where the link reconfiguration request information is used to initiate link reconfiguration; and detecting, by the terminal based on first information, a physical downlink control channel (PDCCH) during a first time period after the moment n. The first information includes QCL information of a first reference signal and a second reference signal. The first reference signal is used to demodulate the PDCCH. The second reference signal is a reference signal meeting a first threshold.

Abstract: An interference power measurement method and a device are provided. The method includes: receiving, by a terminal, first signaling that carries first indication information, where the first indication information is used to indicate n first channel state information-reference signal CSI RS resources, and a jth first CSI RS resource is associated with a power parameter Pc,j; and sending, by the terminal, a channel quality indicator CQI, where the CQI is determined based on a total interference power. The total interference power is a linear weighting result of an interference power measured on each of the n first CSI RS resources and an interference power I0 measured on a zero power CSI RS resource. A weighting coefficient of an interference power Ij measured on the jth first CSI RS resource is a function of the power parameter Pc,j, and a weighting coefficient of I0 is a function of 1 - ∑ j = 1 n P c , j .
