After the big impact of optical 3D-imaging processing, multi- and hyperspectral imaging solutions will be the next technological innovation in image processing for industrial application. This work presents a clever and affordable solution for multispectral imaging: a smart imager for measurements spanning 400 nm to 950 nm in a 50 nm step with 50 nm bandwidth. With a combination of industrial interface...
The combination of the multispectral imaging and the 3D imaging in one system would render possible varieties of applications in different fields. In this work a method is proposed for the registration of multispectral data and 3D point cloud, in which the number of spectral bands is increased by combining different multispectral images through 3D information. Based on this method, a 3D multispectral...
The measurement of dark measurement objects with difficult surface characteristics is always a challenging task. Especially the measurement of pipes which cannot be measured in transmitted light conditions will lead to complicated situations during the image processing and the ongoing feature detection. In this paper two different methods will be presented which will overcome this problem. A quality...
The sharpness of edge transition is one of the major requirements in optical sensing especially in the field of image processing. Therefore a lot of algorithms were assessed in the field of digital photography. In the field of industrial image processing especially multispectral imaging different focus positions are needed to get an optimal focus position for every sampling channel. Therefore a control...
Multispectral imaging technology enables a lot of possibilities in industrial imaging and automation. Especially parts which are complicated for inspection can be inspected using more than one or three wavelength channels. One challenge is the use of all channel information in the multispectral image for the edge detection. For this purpose different approaches were investigated. The results of the...
Virtual contrast enhancement allows a high speed illumination sequence set optimization for high precision measurement tasks. Therefore an FPGA controls the illumination and processes a captured image stack inside the camera.
The Multispectral Imager combines parallel FPGA Hardware with modular and high dynamic mechanical design. Integrated processing and an interconnection to all electromechanical parts enable a real time image correction and processing with lowest latency time.
For the use of image processing systems as fast but accurate measuring equipment, the precision of the image capture is a crucial feature. In addition, larger amounts of data must be processed as achievable sensor resolutions and frame rates increase steadily. The Department of Quality Assurance and Industrial Image Processing of the Ilmenau University of Technology has developed a sensor platform...
