This invention relates to the field of computer vision technology, and particularly to a method and system for multi-scale segmentation of tunnels with multiple defects in low-light environments. The method includes: constructing a smoothing and sharpening module to perform noise reduction and sharpening processing on the input image; improving EfficientNetV2 and using it as the backbone network to extract features from the image; adding an adaptive image enhancement S-curve during progressive downsampling to adaptively enhance the dark areas of the feature map and reduce the highlights; feeding the feature map into an improved pyramid pooling module for multi-scale feature extraction, with each scale's feature map undergoing dimensionality reduction using a Hilbert curve and then performing self-attention mechanism calculations to obtain spatial information from the image; fusing the multi-scale feature maps through channel attention and upsampling to the original image size to obtain the defect segmentation map. This invention addresses the problem of low segmentation accuracy caused by limited image quality generated by drones in dark tunnels by designing an adaptive S-curve enhancement curve and adding it to the segmentation network.

The application discloses an array substrate and a display device. The array substrate comprises a substrate, an array layer and a conductive assembly; the substrate comprises a main body part and a connecting part; the array layer is arranged on the substrate and corresponds to at least the main body part, and the array layer is provided with a pixel circuit; the conductive assembly is arranged on the connecting part of the substrate and is electrically connected with the pixel circuit; wherein the connecting part is arranged at an end of the substrate, and the thickness of the connecting part is smaller than that of the main body part. In the above manner, the reliability of the array substrate can be improved, and the display effect of the display panel can be improved.
