8 results about "Darkness" patented technology

Darkness, the polar opposite of brightness, is understood as a lack of illumination or an absence of visible light. Human vision is unable to distinguish color in conditions of either high brightness or high darkness. In conditions with insufficient light levels, color perception ranges from achromatic to ultimately black.

Brightness and darkness line correction method and device of display screen, electronic equipment and storage medium

PendingCN122454851AEngineeringDark line
The application relates to a display screen light and dark line correction method and device, electronic equipment and a storage medium. The method performs self-calibration between a lamp plate and a camera on an external parameter conversion matrix according to first positions and second positions of a plurality of first lamp beads on a single lamp plate. The position of a second lamp bead at the edge of two adjacent lamp plates is obtained according to the self-calibrated external parameter conversion matrix. Since the position information of the plurality of lamp beads on the single lamp plate is used to obtain the external parameter conversion matrix, the denoising effect can be achieved, and the position error of the second lamp bead is reduced. The joint seam spacing at the edge of the two adjacent lamp plates is obtained according to the position of the second lamp bead, and the detection error of the joint seam spacing is reduced. The display screen is corrected according to the joint seam spacing, and the accuracy of the light and dark line correction is improved.

Image processing method, apparatus, readable medium and device

This application relates to the fields of computer and mechanical control technology, and discloses an image processing method, apparatus, readable medium, and device. The method includes: performing a negative-like processing on an image to be processed to obtain a processed image; fusing the image to be processed and the processed image to obtain a target processed image; and controlling a laser to perform laser processing according to the target processed image. The technical solution of this application's embodiments, by performing a negative-like processing on the image to be processed, increases the brightness of areas in the processed image that correspond to dark areas in the same location as those in the image to be processed. This allows for better neutralization of dark areas during subsequent image fusion between the processed and the image to be processed, preventing large areas of darkness in the generated target processed image. This effectively avoids problems such as material scorching during laser processing, thereby improving the laser processing effect.

System and method for binarizing images

The present disclosure relates to a system (200) and a method (600) for binarizing one or more images using one or more vision transformers (206a, 206b). The system (200) includes an encoder (204) configured to receive multimodal inputs including an original image and a darkness image corresponding to the original image from an input module (202), discretely extract, by vision transformers (206a, 206b), modality-specific features from each of the original image and the darkness image, and aggregate augmenting features among the modality-specific features by determining a weighted sum of the modality-specific features of each of the original image and the darkness image. The system (200) includes a decoder (208) operatively connected to the encoder (204), and configured to reconstruct a binarized output image corresponding to the original image by refining the one or more aggregated features.

A LED directional lighting system for uniform lighting of a facade of a long and narrow passage

This invention discloses a stacked LED directional lighting system specifically designed for laying hen houses, featuring facade lighting that differs from the horizontal lighting focus of ordinary lighting systems. The system comprises double-U directional lights, a directional rotation adjustment mechanism, and spaced T-shaped conductors. The lights incorporate a symmetrical double-U-shaped reflective light control structure and a double-LED plate. Utilizing a customized light distribution curve, it avoids the near-brightness and far-darkness defect, achieving reasonable light intensity supplementation between near and far cages, forming a light distribution distribution with raised sides and a recessed center. The directional rotation mechanism can adjust and lock the light fixture angle, ensuring uniform light output from the multi-lamp array. Combined with high and low-position suspension, it achieves uniform lighting on both sides of narrow passageways without adding lights, increasing costs, or increasing energy consumption. The system is adjustable in size, offers optional lampshades, is fully sealed for dust and moisture protection, and its lighting parameters meet livestock and poultry farming environmental standards. It can reduce stress on laying hens, improve egg production performance, is energy-efficient, easy to operate and maintain, and has significant industrialization and patent application value.

Lighting equipment, lighting control equipment

The present invention provides a lighting device that can illuminate an object by adjusting the brightness and darkness with a desired resolution. [Solution] The lighting device comprises a control unit that determines a control value corresponding to a dimming value by referring to the correspondence between a dimming value for adjusting the brightness of light emitted from a light source and a control value corresponding to the dimming value, and a drive unit that generates a drive signal based on the control value determined by the control unit and supplies it to the light source. The correspondence includes a first correspondence between a dimming value having a first setting resolution and a control value associated with the dimming value having the first setting resolution, and a second correspondence between a dimming value having a second setting resolution different from the first setting resolution and a control value associated with the dimming value having the second setting resolution, wherein the second correspondence is generated based on the first correspondence, and the control unit selects either the first correspondence or the second correspondence to determine the control value corresponding to the dimming value.

Face recognition-based built-in ultra-narrow identification door system

PendingCN122336818APattern recognitionFacial region
This invention relates to the field of smart home technology, specifically to a built-in ultra-narrow recognition gate system based on facial recognition. The system includes a proximity detection module to locate facial regions and generate an image grayscale matrix; a contour extraction module to identify boundary transition positions and generate a contour curvature sequence; a gradient filtering module to compare edge changes and generate a curvature gradient identity list; a proportion construction module to identify facial features and establish proportional relationships to generate a facial matching list; and a gate control execution module to compare authorization and control the gate's opening and closing to generate the final access recognition result. This invention uses entrance proximity signals and lighting brightness as the basis for environmental perception, generating a stable facial grayscale matrix that has undergone brightness and darkness verification. It extracts the curvature and transition continuity of the jawline, cheekbones, and forehead contours to complete multi-region identity screening. Combined with the proportional features of eye spacing, chin verticality, and mouth horizontality, it forms a dual-constraint identity confirmation basis of curvature and proportion, improving the reliability of entrance recognition and the stability of access control in complex environments.
