为提高儿科支气管镜可视化探测识别能力,提出基于TV系统的儿科支气管镜可视化技术。首先进行系统总体设计,在此基础上,构建传感器模块进行儿科支气管镜的视觉信息采集。构建儿科支气管镜可视化分析的图像处理模型,采用边缘轮廓检测算法实现对儿科支气管镜的可视化图像特征提取,完成可视化图像像素的空间重构。在此基础上,进行儿科支气管镜可视化重构。最后,构建儿科支气管镜可视化系统的硬件模块,选用Proline Promag作为主控制器,通过采用嵌入式的UML和组件联合控制方法,实现儿科支气管镜可视化系统的硬件开发,并最终完成儿科支气管镜可视化系统的开发设计。测试结果表明,设计系统输出信噪比最高可达到100 dB,辨识度水平最高可达到99%,以期为提高儿科支气管镜可视化探测识别能力提供一定帮助。

In order to improve the visual detection and recognition ability of pediatric bronchoscope,a visual technology of pediatric bronchoscope based on TV system was proposed.Firstly,the overall design of the system is carried out.On this basis,the sensor module is constructed to collect the visual information of pediatric bronchoscopy.The image processing model of pediatric bronchoscope visual analysis was constructed,and the edge contour detection algorithm was used to extract the visual image features of pediatric bronchoscope,and the spatial reconstruction of visual image pixels was completed.On this basis,visual reconstruction of pediatric bronchoscopy was carried out.Finally,the hardware module of pediatric bronchoscope visualization system is constructed,and proline promag is selected as the main controller.The hardware development of pediatric bronchoscope visualization system is realized by using embedded UML and component joint control method,and finally the development and design of pediatric bronchoscope visualization system is completed.The test results show that the output signal-tonoise ratio of the designed system can reach up to 100 dB,and the recognition level can reach up to 99%,so as to provide some help for improving the visual detection and recognition ability of pediatric bronchoscopy.
