摘　　要：论文针对电子内窥镜摄像头在高能量激光刀手术中的过曝光现象以及成像变暗等问题设计出一种基于GPU图像处理视频转录系统。利用过曝帧与正常帧的像素值差异以及前后图像帧的亮度关系,提出了一种自适应阈值的滤光增亮算法并采用GPU并行加速。实验结果表明,该系统对过曝帧的滤光率达到了97%,在确保激光手术中的正常实时成像的同时改善了内窥镜成像质量,有较大应用价值。In this paper,a video transcription system based on GPU image processing is designed to solve the problems of overexposure and image darkening of electronic endoscope camera in high-energy Laser scalpel surgery.Based on the difference of pixel values between the over exposed frame and the normal frame,and the relationship between the brightness of the front and back image frames,a light filtering and brightening algorithm with an adaptive threshold is proposed and accelerated by GPU.The experimental results show that the filter rate of the system can reach 97%,which can not only ensure the normal real-time imaging in laser surgery,but also improve the imaging quality of the endoscope,and has great application value.
