    摘要： Provided are a method and apparatus for processing immersive media data, a storage medium, and an electronic apparatus. The method comprises: acquiring immersive media data corresponding to a current viewing posture of a user, wherein a three-dimensional viewing space is used to limit viewing content of the user; and rendering the immersive media data corresponding to the current viewing posture, wherein when the current viewing posture is within the three-dimensional viewing space, the acquired immersive media data is rendered; or when the current viewing posture has moved or is moving outside the three-dimensional viewing space, the immersive media data is rendered according to handling information of the three-dimensional viewing space, The present invention solves the problem of the rendering and presentation of visual content viewed by a user being affected, thereby achieving quick, efficient and high-quality reconstruction and rendering of visual content during viewing, so as to satisfy the optimal immersive experience effect.

    摘要： Provided by the present invention are a method and system for automatically optimizing 3D stereoscopic perception, and a medium. The method comprises the following steps that are executed successively: step 1: given current left and right images, calculating a stereo disparity to generate a disparity map; step 2: calculating a depth value corresponding to each individual pixel by using the calculated disparity; step 3: calculating a depth distance of a target to be observed; step 4: acquiring corresponding left and right image displacement values by using the depth distance calculated in step 3; and step 5: applying the acquired image displacement values into a 3D display. The beneficial effect of the present invention is that: the method for automatically optimizing 3D stereoscopic perception according to the present invention solves fatigue and dizziness that are easily generated during the use of a 3D endoscope. By means of automatic optimization, symptoms can be alleviated, guaranteeing user comfort for a long time.

    摘要： An image display method, an apparatus, and a system are provided, to resolve a prior-art problem of an excessively high display latency in cloud VR. In this application, a terminal device sends first information to a cloud device, where the first information indicates a posture and a location of the terminal device at a first moment. Then, the terminal device receives information about a first field of view image from the cloud device, where the first field of view image is a field of view image corresponding to the posture and the location of the terminal device at the first moment. The terminal device displays an image within a field of view range of the terminal device at a second moment based on the information about the first field of view image and a posture change and a location change of the terminal device from the first moment to the second moment. This can effectively shorten a time period from the second moment at which the posture and the location of the terminal device change to a moment at which the terminal device displays the image within the field of view range of the terminal device at the second moment, thereby reducing an image display latency and further improving user experience.
