For real-time measurements during the construction of the concrete pump truck boom shake,one displacement measuring method based on video processing is introduced in this paper, which can measure the displacement of flexible boom accurately.This method analyze the video of the marking object on flexible boom's movement one frame after another or one next to another with the help of powerful video processing ability of MATLAB.By binary processing and background subtraction,and use the relative continuity of video capture,dynamic background correction algorithm proposed to enhance the adaptability of the background changes,moving target extracted;In measurement with median filter method to filter the salt and pepper noise reduce the interference of background noise on the target,put forward difference threshold prediction method,dynamic prediction next frame target areas,which search out the scope of threshold value, actively predict the objected realm of next frame,and eliminate the background disturbers to the object as much as possible,the displacement measuring is realized.This method's possibility is proved by testing the boom of concrete pump,the test result shows that the error of displacement measuring is within 5mm which can meet the need.
With the continuous breakthrough of science and technology, all aspects related to science and technology are constantly updated and changing. Photoelectric devices, also known as photosensitive devices, work on principles based on the photoelectric effect. The application of photoelectric devices in our lives is also diverse. This paper aims to study the flexibility of nanophotoelectric devices, which is a new generation of photoelectric device product technology, making photoelectric devices have more outstanding utility compared with the past. In the traditional sense, photoelectric devices will have their own hardware defects, and the update of nanoflexible photoelectric device technology will solve the above shortcomings. The above breakthroughs in key technologies have improved the hardware of welding tooling in the industrial field. The technique of welding tooling is widely used in the industrial field. The introduction of nanoflexible photoelectric devices into the welding tooling can overcome the defects of conventional processes. This paper proposes the application of nanotechnology in the industrial field. A parameter testing system and a model of dynamic matrix predictive control are established to predict and control the parameters of the experiment throughout the process. The experimental object of this paper is nanoflexible optoelectronic devices; meanwhile, the concentration of nanomaterials in the nanophotoelectric device plays a decisive role in the efficiency of the device, then the final experimental results show that when the concentration of nanomaterials is 8.5
