The invention relates to an image processing system for omnidirectional reading of optical patterns, for example of one-dimensional and two-dimensional codes. One object is to provide an image processing system which ensures high resolution with rapid processing at the same time in order, in particular, to allow processing in video real time and to provide reliable identification of the image information, in particular reliable and low-error edge detection, segmentation and object association. According to the invention, this is achieved by the use of a plurality of convolvers, which operate in parallel and/or using the time-division multiplexing method, for convolution of the digital image data, of a neighborhood processor () for reading and linking contour points (), and/or of a statistical processor for reading a segment list.

Image processing system

A sensor unit ( ), a device, and a process for inspection of a surface ( &Dgr;) of an object ( ) for the purpose of identifying surface characteristics, such as structural defects. The device contains an emitting module ( ) and a receiving module ( ). The emitting module emits at least one beam bundle ( &Prime;). The receiving module has at least one light receiver ( ). A rotating polygonal mirror wheel ( ) is located in the focal point of a parabolic mirror ( ). A beam bundle ( ) of the laser ( ) is directed onto the mirror ( ) by means of a telecentric lens, which guides the emitter and receiver beam on the same optical axis, whereby the parabolic mirror ( ) guides the deflected beam bundle ( &Prime;) under a constant angle relative to the axis of symmetry ( ) of the parabolic mirror ( ) along a scanning line ( ) over the object ( ). The diffusely reflected beam bundle, after being deflected out of the common beam path, impinges on the processing unit ( ).
