Stereo vision systems can automatically identify and locate targets within their field of view, enabling on-site calibration even in complex environments. By identifying and locating feature points on a moving object and analyzing the data, the system can further obtain the object's 3D coordinates, orientation, and relative distances between feature points. Below, the China Machine Vision Mall provides a brief introduction to stereo vision systems used for the inspection of electrical components and 3D printing.
The inspection of electrical components and parts is a crucial step in the manufacturing process. Generally, when measuring the coordinates of points on the surface of a part, a coordinate measuring machine (CMM) is used offline to obtain relatively accurate data. However, this conventional contact measurement method has some limitations. For example, measuring the entire outer surface of a part can be extremely labor-intensive, or even impossible. Furthermore, measuring points that the probe cannot reach is even more challenging, making online measurement extremely difficult.
However, in automated production processes, online measurement of parts is required to ensure the continuity of production. Due to the unevenness of components, stereo vision inspection technology is needed for real-time online inspection of electrical components. During inspection, based on the actual needs of the production process, a method for online measurement and accuracy analysis of parts is established using machine vision principles. Cameras pre-installed in the system capture stereo images of the parts on the production line. These stereo images are processed to extract the three-dimensional information of the part's surface, thereby calculating the three-dimensional coordinates of points on the part's surface. However, very high accuracy is required, so lenses with low distortion rates and high floating-point accuracy must be selected.
3D printing, also known as stereoscopic printing, is a type of printing that can realistically reproduce objects with a strong sense of three-dimensionality. It produces clear, richly detailed, lifelike images with profound meaning. Furthermore, it boasts numerous advantages such as instant curing, environmental friendliness, high quality, and energy saving. These advantages make it widely applicable to three-dimensional anti-counterfeiting packaging for alcohol, tobacco, and general merchandise, as well as stationery, calendars, advertising materials, posters, various cards, and hang tags.
The original artwork for 3D printing is often a design or a photograph of a scene. The printed product is usually printed on high-quality coated paper and high-temperature resistant ink, so it has good gloss, bright colors, and is not easy to fade. In addition, the surface of the printed product is covered with a layer of lenticular lens plate, which allows you to directly view the 3D effect of the panoramic image.
Currently, 3D image printing is becoming increasingly common, and market demand is leading to a greater application of stereoscopic vision technology for 3D printing inspection. This involves using multi-view cameras with stereoscopic vision to control the vertical movement of the nozzles for inspection, ensuring high-quality printing products.
