The utility model discloses a kind of intelligent dimming control device based on human body response, by adopting double pyroelectric infrared sensor, each is equipped with independent fresnel lens, both can be arranged in different positions or angle cooperative work, can cover more wide space area, effectively reduce detection blind area, independent fresnel lens can be designed according to sensor position and detection demand pertinence, adjust focal length, viewing angle and the like parameter, make sensor accurate receiving human infrared radiation, optimize for different direction and distance human activity, improve detection sensitivity and accuracy, whether there is human existence according to whether the signal strength output by human body response module exceeds the set threshold value by microcontroller module, this kind of judgment based on signal strength is more accurate, LED load module receives the electric energy and PWM signal of dimming drive module, according to the duty ratio change luminous brightness of PWM signal, can realize the smooth and accurate regulation of LED light brightness, provide more intelligent, comfortable lighting experience for user.

This invention discloses a multi-level intelligent route caching management method, including: obtaining tab operations, such as opening a tab, closing a tab, and refreshing a tab; obtaining the route object of the current tab corresponding to the tab operation; updating the tabs in the visited route array based on the route object; and updating the cache list based on the updated visited route array. Updating the cache list based on the updated visited route array ensures that the cache is updated synchronously when tabs change, and the cache corresponding to closed tabs can be automatically cleared, which also helps avoid wasting memory. When the tab operation is to refresh a tab, only the pages that need to be refreshed are rendered, destroyed, and re-rendered to refresh the specified tabs, while other tabs that do not need to be refreshed remain in a cached state, avoiding page flickering and achieving fine-grained control over page refresh.

The invention discloses a video rendering method, electronic equipment and a storage medium. The method comprises the following steps: acquiring a to-be-processed video and a target illumination instruction; determining a second image sequence according to the to-be-processed video and the target illumination instruction; for each second image in the second image sequence, performing affine transformation on the second image through an iteratively adjusted appearance feature matrix until the second image after the affine transformation meets a first preset condition, and obtaining a third image sequence corresponding to the second image sequence; obtaining an index corresponding to each pixel point in the third image sequence, and obtaining an index set corresponding to all pixel points in the third image sequence; determining a unified video tensor according to pixel colors corresponding to the same indexes in the index set; and iteratively adjusting the unified video tensor, so that an image sequence reconstructed based on the adjusted unified video tensor meets a second preset condition, and a fourth image sequence is obtained.
