This invention discloses a method and system for optimizing stereoscopic vision on naked-eye 3D large screens, specifically relating to the field of naked-eye 3D vision optimization technology. The method includes: real-time perception of ambient light and viewer position through multi-sensor fusion to establish an ambient light field model; prediction of glare crosstalk noise based on physical simulation, and adaptive suppression and compensation combining human visual sensitivity and image content features; dynamic generation of a virtual camera based on the viewer's real-time binocular positions, and real-time re-rendering using a lightweight neural radiation field renderer to achieve motion parallax; finally, intelligent fusion and encoding of the glare compensation layer and perspective correction layer, and outputting the result to the screen. The system includes four main modules: environmental perception, glare compensation, perspective rendering, and fusion encoding. This invention effectively suppresses ambient light interference, improves the quality and immersion of stereoscopic images from different viewing angles, and is suitable for naked-eye 3D large-screen displays in outdoor and complex lighting environments.

This utility model belongs to the technical field of pig disease prevention equipment, and particularly relates to a long-pole blindfolded pig-catching device for disease prevention. Addressing the problem that existing devices do not obstruct the pig's vision, leading to heightened visual sensitivity and heightened alertness to environmental changes, resulting in panic, severe stress, and continued struggle even when restrained, easily causing injury and increasing health risks, the following solution is proposed: a long-pole blindfolded pig-catching device for disease prevention, including a connecting block with a steel band fixedly mounted on its surface. The advantages of this utility model are: the device is easy to operate; the control lever and U-shaped clamp can quickly tighten the steel band; the connecting rod, adjusting rod, and extension rod are detachable; a single person can handle different scenarios, reducing labor costs and complexity; a dark cloth bag simultaneously blindfolds the pig, a sponge ring provides cushioning, and a spring provides elastic locking, reducing stress and injury to the pig; the steel ring is adjustable to fit pigs of different sizes; one device meets diverse needs.

This invention proposes a differentiated collaborative animal repelling system and method for substations. The system includes a front-end detection module that monitors the substation's monitoring area, collecting the target's location, movement trajectory, morphological features, sound characteristics, thermal imaging information, and image information. An AI fusion control module acquires the target's location, movement trajectory, and thermal imaging information, sequentially determining whether the target has invaded, whether the invading target is an animal, and the initial target classification result. After determining that an animal has invaded the substation area, a preliminary repelling strategy is determined based on the initial classification result. The front-end detection module then acquires the animal target's morphological features, sound characteristics, and image information again, and based on these, determines the animal target's species type. Furthermore, based on the animal target's species type and the species repelling strategy database containing the animal target's visual sensitivity, acoustic sensitivity, and auditory fear sources, a final repelling strategy is determined for the current animal target. The repelling execution module then repelles the animal target according to the preliminary and final repelling strategies determined by the AI ​​fusion control module.
