PURPOSE: To solve the deterioration of the tracking accuracy of a work by updating the position of the work based on the moving speed of a conveyor after the position of the work is calculated. CONSTITUTION: Movement of a conveyor from the previous sampling to this sampling is calculated (SP1), the increment of the encoder pulse contained in the work data is updated (SP2), and a judgment (SP3) is made whether or not the encoder pulse contained in the work data of all works to be tracked is updated. When the increment of the encoder pulse of all work data is updated, a judgement (SP4) is made whether or not the image incorporated by an image processor is being tracked, and if the image incorporated by the image processor is being tracked, the increment of the encoder pulse contained in the view data is updated (SP5) to complete a series of processings. If the image incorporated by the image processor is not being tracked, a series of processings are completed without any change. |
