A camera for industrial image processing having a camera module and an objective module that is releasably connected thereto and has an optical system having at least one optical lens preferably comprises&#x2014;in the camera module&#x2014;an image sensor for capturing an image and a camera control unit for controlling the camera module and/or the objective module, and&#x2014;in the objective module&#x2014;a storage unit having lens data, wherein interacting wireless near field communication units are provided in the camera module and in the objective module, wherein the near field communication unit in the objective module converts an electromagnetic alternating field emitted from the near field communication unit in the camera module into electrical energy for supplying energy to the objective module, and the camera module reads the lens data out via the near field communication units, and the camera control unit controls therewith a function of the camera module and/or of the objective module.

Camera for industrial image processing

To produce a real-time smart camera that can be flexibly configured in terms of hardware, a camera core is provided. The camera core is designed as a hardware arithmetic logic unit, and a real-time data bus interface, for connecting a real-time data bus, and a camera control unit are additionally provided in the camera core. The camera control unit is connected to both the real-time data bus interface and the image sensor interface, and the camera control unit is actuated via the real-time data bus interface to prompt the capture of an image. The camera control unit controls the image sensor interface.

To correct aberrations in the image plane of a camera while modifying selected, modifiable camera settings that influence aberrations quickly and simply, a plurality of features with different known feature positions is provided in space. For each selected, modifiable camera setting influencing the aberration, at least two defined setting specifications are provided for modifying respective camera settings. For each setting specification, the camera captures the plurality of features. The camera determines positions of features in the image plane. Via a known mathematical method, a connection between different known feature positions in space and corresponding image positions in the image plane of the camera is determined. For each of the setting specifications of the selected modifiable camera settings, correction parameters of at least one mathematical correction model are determined for correcting the aberration. The at least one correction model is stored in the camera together with the determined correction parameters.

To provide an illuminator, which offers reliable protection against undesirably high levels of emitted light intensity, there is provided on the illuminator according to the invention, in addition to a light source and a control unit, which supplies the light source with an electric current or an electric voltage and is equipped to regulate the intensity of an emitted light via the electric current or the electric voltage, a detector, which captures at least a performance variable of the light source. In addition, a diagnostic unit is provided, which compares the at least one performance variable against at least one specified limit value and triggers an action, which reduces the intensity independently of the control unit, as soon as the at least one performance variable reaches or exceeds the at least one limit value.
