摘要
针对还童监理系统易受到视频监控图像模糊性的影响,导致输变电工程监控输出的动态识别能力较差的问题,提出基于三维模型的输变电工程智能监理系统设计方法。在空间坐标系中,定位监理图像特征点,获取图像特征几何动态约束分布集,以分布集为量化中心,得到图像的灰度像素集,量化输出灰度像素集的向量,提取输变电工程监理的三维图像的特征。由几何不变矩计算监理图像的边缘轮廓的幅值,对采集的监理图像进行滤波处理。在此基础上,计算输出图像降噪的标准差,得到信息增强输出,构建输变电工程监理的三维模型。在嵌入式ARM环境中,以CMOS红外图像采集仪为采集硬件,PCI9054的LOCAL总线做远程控制,I/O0~I/O7作为并行接口转换控制输出,ADSP-BF537作为外围器件等完成系统硬件设计。测试结果表明,设计的系统能有效实现输变电工程智能监理和三维建模,监理过程的稳态性较好,系统可靠度较高。
Aiming at the problem that the child supervision system is affected by the ambiguity of the video surveillance image,which leads to the poor dynamic recognition ability of the power transmission and transformation project monitoring output,a three-dimensional model-based intelligent supervision system design method for power transmission and transformation engineering is proposed.In the space coordinate system,the image feature points of the supervision image is located,the geometric constraint distribution set of the image feature is obtained,and the distribution set as the quantization center is used to obtain the gray pixel set of the image,the vector of the output gray pixel set is quantized,and the power transmission and transformation project is extracted.The characteristics of the three-dimensional image of the supervisor.The amplitude of the edge contour of the supervised image is calculated from the geometric invariant moment,and the collected supervised image is filtered.On this basis,the standard deviation of the output image noise reduction is calculated,and the information enhancement output is obtained,and the three-dimensional model of the power transmission and transformation engineering supervision is constructed.In the embedded ARM environment,the CMOS infrared image acquisition device is used as the acquisition hardware,the LO905 bus of PCI9054 is remotely controlled,I/O0~I/O7 is used as the parallel interface conversion control output,and ADSP-BF537 is used as the peripheral device to complete the hardware design.The test results show that the designed system can effectively realize the intelligent supervision and three-dimensional modeling of power transmission and transformation engineering.The stability of the supervision process is better and the system reliability is higher.
