Automation of optical quality control in the example of the furniture industry

Maj Michał, Pliszczuk Damian, Cieplak Tomasz

Przegląd Elektrotechniczny

2023

R. 99, nr 1

245--248

A prototype of a quality control system based on optical detection algorithms will be presented here. In its functionality, it will include an exemplary web application used by the customer to place an order - in this case, a wardrobe, based on which an employee will be able to control the quality of the order and, more precisely - to check whether the components of a given order in the warehouse have not undergone the ageing process, e.g. paintwork.

Przedstawiony został prototyp systemu kontroli jakości opartego na algorytmach detekcji optycznej. W swojej funkcjonalności zawiera przykładową aplikację webową, za pomocą której klient może złożyć zamówienie – w tym przypadku szafę, na podstawie której pracownik będzie mógł kontrolować jakość zamówienia, a dokładniej – sprawdzać, czy poszczególne elementy danego zamówienia, jak np. lakier, nie zostały poddane procesowi starzenia się.

To overcome the depth-of-field limitation of an optical microscope image, a three-dimensional measurement method with a superior depth-of-field is proposed. In the proposed method, light-field information of different angles is obtained by moving the aperture and the three-dimensional scene is reconstructed by using a computational reconstruction technology. First, stereo matching of different aperture position images is performed to obtain the multi-aperture imaging deviation. The focal plane moving distance is thereby estimated. Then, the relational expression between the image coordinates and the focal plane moving distance is determined according to the image coordinates. Two dimensional coordinates of the space point are obtained by the expression coefficients. Finally, the depth coordinates are computed, and three-dimensional reconstruction of the spatial points is completed. Experiments of three-dimensional measurements of the calibration board with different angles and circuit boards are conducted. The results show that the maximum error of the distance measurement is controlled into 0.84%, and the maximum angle measurement error is controlled into 4.56%.
