Image processing method and apparatus, electronic device, and computer-readable storage medium

The present disclosure provides an image processing method and apparatus, an electronic device, and a computer-readable storage medium. The method includes: obtaining a to-be-processed video comprising m frames of images, m being a positive integer greater than or equal to 2; placing a three-dimensional model on a target plane of a first frame of image of the to-be-processed video, a plurality of feature points of a model surface of the three-dimensional model falling on the target plane; determining three-dimensional coordinates of the plurality of feature points of the model surface in a world coordinate system and pixel coordinates of the plurality of feature points of the model surface on the first frame of image; determining, according to the three-dimensional coordinates of the plurality of feature points of the model surface in the world coordinate system and the pixel coordinates of the plurality of feature points of the model surface on the first frame of image, a pose of a camera coordinate system of the first frame of image relative to the world coordinate system; determining, according to the target plane, the three-dimensional coordinates of the plurality of feature points of the model surface in the world coordinate system, and the pixel coordinates of the plurality of feature points of the model surface on the first frame of image, poses of camera coordinate systems of a second frame of image to an mframe of image of the to-be-processed video relative to the world coordinate system; and replacing the three-dimensional model with a target model and placing the target model on the world coordinate system to generate, according to the pose of the camera coordinate system of each frame of image of the to-be-processed video relative to the world coordinate system, a target video comprising the target model.

A data processing method is performed at a terminal. The method includes: generating a supplementary signal frame according to a first original signal frame of a first data collector when a first frame rate of the first data collector in a terminal is less than a second frame rate of a second data collector, and determining an input time stamp of the supplementary signal frame according to the second frame rate; inputting the supplementary signal frame into a first input queue of the first data collector when a current time reaches the input time stamp of the supplementary signal frame; obtaining a second original signal frame that is currently input into a second input queue and that is of the second data collector; and performing signal fusion on the supplementary signal frame in the first input queue and a second original signal frame in the second input queue.

Data processing method, computer device and storage medium

The various embodiments described herein include an information processing method performed by a wearable electronic device. The wearable electronic device obtains a first initial media file and a second initial media file for a target area. The first initial media file includes a first image acquired based on a first location of the target area. The second initial media file includes a second image acquired based on a second location of the target area. Based on the initial files, the wearable electronic device determines depth information of each target point in the target area. Next, the wearable electronic device selects a first media file from the first and second initial media files, and calculates a second media file. The wearable electronic device then outputs the first and second media files to, respectively, a first output unit and a second output unit of the wearable electronic device.
