Lighting is an important factor in the impact of the machine vision system input, which directly affect the quality and application of results of the input data. In the absence of a common machine vision lighting, so for each particular application instance, to select the appropriate lighting fixtures, molds monitored to achieve the best results. Light source can be divided into visible and invisible. Several commonly used visible light sources are incandescent lamps, fluorescent lamps, mercury and sodium light. Disadvantage is that the visible light can not remain stable. How to light a certain extent, remain stable, the process is a practical need to solve problems. On the other hand, ambient light may affect the image quality, so can add shield of ways to reduce the impact of ambient light. The illumination system according irradiation method can be divided into: back lighting, forward lighting, the structure of light and strobe lighting. Among them, the back lighting is measured object placed between the light source and the camera, and its advantage is to obtain a high-contrast images. Forward illumination light source and the camera on the same side of the measured object, mold monitoring apparatus, in this way is easy to install. Structured light illumination source is a line grating or the like is projected onto the measured object, according to the distortion they produce demodulated three-dimensional information measured object. Strobe lighting is a high-frequency pulse irradiation light onto the object, the mold monitor, video camera and light synchronization requirements. Gating system classification categories according to the gating system made of different type plastic molds can be divided into: (1) large outlet die: runner and gate at the parting line, together with the product ejection when the mold, the most simple design mold monitor, easy processing, low cost, so more people work with large intake system. Plastic mold structure is divided into two parts: the movable mold and the fixed mold. With injection moving part of the movable die (mostly top out side), the exit end of the injection machine is generally referred to as the fixed mold inactivity. Large part due to the fixed mold outlet mold generally consists of two steel plates such structures it is also called mold as the "two-plate mold." Two large outlet formwork mold simplest structure.
