Abstract: The present system enables the monitoring and automatic control of the tolerance in splice overlap of textile play , though the identification of the overlap area, identification and counting of textile cords in the overlap area, and the generation of a control signal for the manufacturing equipment based on parameters and criteria defined by a user. The system includes an image acquisition sub-assembly that contains a lighting module, artificial vision module, and respective elements of support, fixation, conditioning and adjustment. The system also includes a quality control computer program that has a module of morphologic image analysis for detection and recognition of the overlap of the ply, detecting and counting of cords in the overlap area, a module of support to the decision of acceptance/rejection of the ply based on parameters defined by the user and a module of an interface with production equipment.
