  “Display image” is an item for selecting a display method for displaying a camera image in the vision view window 44, and either a registered image or a filter image can be selected as the display method. When the registered image is selected, the camera image registered in advance and used for image processing in the processing unit selected on the flowchart is displayed as a through image as it is. On the other hand, when a filter image is selected, a camera image used for image processing in the processing unit and including image data after filter processing performed as preprocessing of processing for obtaining a measurement result is filtered. Displayed as a processed image.

  Here, the filter processing performed as preprocessing is image conversion processing performed on a camera image in order to increase measurement accuracy. From a series of image processing for obtaining measurement results, a large number of pixel data are used. The processing is to generate a two-dimensional output image from the two-dimensional input image. On the other hand, the process for obtaining the measurement result is a process that is performed after the pre-processing, and is a process for generating a numerical value such as a measurement value from a two-dimensional input image.

  For example, filter processing such as color extraction, expansion, contraction, and sobel (edge enhancement) is selectively performed as preprocessing. Note that color extraction is preprocessing for generating a grayscale grayscale image or a binarized black and white image by converting a color image.

  “Image setting” is an item for designating a camera image to be processed. “Area setting” is an item for designating an image area to be processed for a camera image. “Detection condition” is an item for designating a processing method and a measurement condition.

That is, all parameters of the processing unit selected as the editing target can be changed on the editing dialog 50, whereas only the parameters permitted to be changed in the editing dialog 50 are displayed on the result view window 45. Its value can be changed.

  Here, a parameter for which a check mark is input to the check box 51 is designated as a global variable, and the value is shared between different parameters or parameters of different processing units. That is, the variable name input in the input field 52 is associated with the parameter that is allowed to be changed, and the value is shared with other parameters associated with the same variable name as this variable name. In this way, the values of the plurality of parameters associated with each other via the variable names are shared, and if any parameter value is changed, the other parameters are changed in the same way.

  Also, parameters that are permitted to be changed in the editing dialog 50 are designated as parameters that can be changed on the image processing controller 11. In other words, only the parameters that are allowed to be changed in the editing dialog 50 can be changed on the image processing controller 11, and the parameters that are not allowed to be changed are restricted from being changed on the image processing controller.

<Result view window>
FIG. 6 is a diagram showing an example of the operation of the PC 2 in the inspection system 100 of FIG. 2, and a result view window 45 on the editor screen 40 is shown.

  Specifically, for the parameters of the processing unit selected on the flow view window 46, the current value 71, the initial value 72, the type information 73, and the type information 74 are displayed in association with the variable names. The parameter current value 71 is data indicating a processing result for each processing unit obtained by executing the inspection setting data being edited.

  The type information 73 is information indicating whether the parameter can be edited on the result view window 45. For example, “local variable” is displayed for the editable parameter, and “result data” is displayed for the data indicating the processing result.

  In this way, the parameters and processing results can be displayed by narrowing down to the processing units selected on the flow view window 46. Also, only the parameters specified in advance in the editing dialog 50 are displayed in the result view window 45, and the parameters for which no check mark is entered in the check box 51 are not displayed. Can be prevented.

  Further, the current value or initial value of the parameter displayed in the result view window 45 can be changed on the window. For example, the parameter can be changed by selecting the parameter to be changed and inputting the key. Further, if an operation input for executing a simulation is performed after such a parameter change, the simulation is executed based on the changed parameter, and the simulation result is reflected in the processing result. As described above, since the simulation result based on the changed parameter can be confirmed on the result view window 45, the operation can be easily confirmed when the parameter is changed.

  FIG. 7 is a diagram showing an example of the operation of the PC 2 in the inspection system 100 of FIG. 2, and shows a result view window 45 on which the processing result of the processing unit is displayed. In the result view window 45, data indicating the processing result of the processing unit selected on the flow view window 46 is displayed together with the variable name.
