The invention relates to the technical field of identification, and discloses an intelligent identification method based on dynamic display, which comprises the following steps: S1, a data acquisition step: acquiring scene environment data and user state data in real time through a deployed environment sensor and a user positioning module; according to the invention, through an environment sensor and a multimode positioning module, multi-dimensional data such as illumination, temperature and humidity, a user position and a moving track are collected in real time, and in combination with a demand classification model driven by deep learning, user demands are accurately divided into three core scenes of navigation guidance, information query and activity reminding. And meanwhile, the priority of the identification content is determined by matching the scene state through the priority ranking model, so that irrelevant information interference of the user can be effectively avoided, the core demand matching accuracy is improved by more than 40%, the method is particularly suitable for complex scenes such as shopping malls and transportation hubs, the user information acquisition cost is remarkably reduced, and the individuation and accuracy of the identification service are improved.

This utility model belongs to the field of LED display technology and discloses an outdoor LED grid display screen, including multiple LED light source emitters arranged in a grid array. Each LED light source emitter includes an emitter body and a light source emitting head. One side of the emitter body is a mounting surface and is mounted on a mounting frame. Multiple light source emitting heads are correspondingly embedded on the end face of the emitter body away from the mounting surface. The light emitted by the light source emitting heads is emitted horizontally in a wide-angle manner. Each light source emitter is equipped with a reflector located above the light source emitting head. One end face of the reflector is an inclined mirror surface, with its lower end abutting against the end face of the emitter body away from the mounting surface and its upper end away from this end face, so as to reflect part of the light emitted upwardly by the light source emitting head in a horizontal direction. This grid display screen can reduce the upward tilt of light and reflect it in a horizontal direction, thereby improving the brightness of the light and the clarity of the display screen.

The invention relates to an infrared image parallel defogging method based on a GPU, and the method comprises the steps: S1, constructing a dark channel fog light image with an infrared image as an input, estimating the transmittance of a scene, and obtaining a GPU transmittance image; s2, taking the infrared image as a guide image, performing guide filtering optimization on the GPU transmissivity image, and outputting a GPU refined transmissivity image; s3, the GPU refinement transmissivity image passes through an atmospheric scattering model to obtain a preliminary defogging image; s4, adjusting a contrast limit parameter according to the estimated scene transmissivity, and enhancing the preliminary defogged image by using a contrast limit adaptive histogram equalization method to obtain an infrared enhanced image; and S5, designing a kernel function by using a GPU parallel language, and executing the processing processes of the steps S1 to S4. According to the method, the real-time requirement of infrared video processing can be met, and meanwhile, the resolution and the visual distance of an infrared image can be improved.
