To address the challenges of low accuracy and difficulty in balancing a large field view long distance when tracking high-speed moving targets with single sensor, an ROI adaptive digital zoom method is proposed. In this paper, we discuss impact on image processing describe design system. Additionally, construct update model based normalized target information. capture changes effectively, introduce multi-scale regional measure propose improved particle filter algorithm, referred to as...
Monocular depth estimation is one of the classic problems in field computer vision. It widely used fields such as 3D scene reconstruction and augmented reality. In this paper, a self-supervised monocular model for dynamic targets designed to solve current unsupervised moving scenes. To problem insufficient accuracy areas, method strengthening fusion local area features with cross-attention mechanism proposed, which refines overall structure, expands receptive enhances representation ability...
Y2SiO5: Ce (YSO) scintillation with characteristics of high light yield, fast decay time, and Compton scattering fraction shows good application potential for imaging. In this article, we propose a 3-D scintillator detector, which is segmented by the YSO monolithic rods pixelated subsurface laser engraving (SSLE) in depth direction. Two arrays silicon photomultipliers are optically coupled to array at each end, pixels designed one-to-one match. By identifying location number measuring...
Based on terahertz frequency modulated continuous wave nondestructive testing system, a ceramic pencil holder was studied. Different types of defects are designed the outer wall pen holder. By using high penetration and non-destructive characteristics waves, time domain, height rotation angle information obtained by scanning in an all-round multi-angle manner, high-resolution three-dimensional images constructed. At same time, processing technology noise reduction is used to optimize images....
In this study, we propose a hybrid coded-aperture and Compton camera based on cerium-doped Gd3Al2Ga3O12 (GAGG:Ce) scintillator arrays coupled with Multi-Pixel Photon Counter (MPPC) arrays. The sensitive detector of the gamma consists single GAGG:Ce crystal single-chip MPPC unit module. An impedance bridge circuit 64-channel data acquisition system were employed to record code-aperture events coincidence events. After calibration position energy, total energy resolution for 662 keV gamma-rays...
