PCI-E image acquisition card for system developers to develop multi-channel video images. It uses PCI-E X 1 bus as the data access channel (independent bandwidth, higher than PCI*** mode), and the bus data transmission rate can reach 250 Mbyte/s. The real-time parallel processing technology makes the image acquisition speed faster, and more channels and larger video images can be acquired. The problem of large-size multi-channel image acquisition and wire drawing of PCI bus video image acquisition card is solved. The super 10-bit AD converter chip has much better image quality and color saturation than 8-bit and 9-bit AD converters. Its 4-wire 3D comb filter can automatically eliminate noise, with better image quality and higher sampling frequency. The animation software does not nap, draw or hide, and the picture quality is greatly enhanced; The performance is more stable.
PCI-E 4 channel real-time image acquisition card is used in traffic intersection electronic police, industrial image detection, large-screen video display and multi-channel image acquisition at the same time, and provides you with a convenient secondary development package (DLL), and even can directly modify the underlying software according to user requirements, so that our image card can better match your system.

Flatness detection is also called frontal detection and flatness detection. The flatness detection system is specially used to detect the horizontal straightness, flatness, gap and pin width of various electronic components such as ic chips and electronic connectors.
At present, a large number of electronic product manufacturers begin to use machine vision inspection system to replace the original manual inspection method. Chip is an indispensable part of electronic products. In the production process of electronic products, multi-pin small pitch integrated circuit devices will be affected by external pressure. Whether the flatness and alignment of their pins are within the precision requirements requires subsequent inspection and correction, and it should meet the requirements of real-time, high-speed and high-precision in the installation process. Therefore, the detection of chip flatness is a very important link.
According to the demand of the industry, VIV Image introduced a flatness detection system based on machine vision technology. Chip flatness detection system is a photoelectric integrated high-precision on-line detection device, which is specially used to detect various ic chip pins and their flatness (horizontal straightness, * * * flatness), gap, pin width and so on. After the system is simply set up, it can automatically identify and detect without personnel operation. It can conveniently, quickly and accurately check the flatness of products, and obviously improve work efficiency and product quality! The system has developed from a single camera flatness detection system to a two-camera, three-camera and multi-camera linkage detection. The single camera flatness detection system can achieve the accuracy of more than 0.0 1mm when detecting the calibrated flatness, and the flatness error range can be set according to the detection requirements.
The technical characteristics of the chip flatness detection system are: the operation interface is clear and simple, and it can be automatically detected by simple setting; The detection software and algorithm are completely independently developed, and sub-pixel technology is adopted to achieve ultra-high detection accuracy; Various detection algorithms such as template search and average gray value detection can be flexibly set; Local scanning function can be selected to improve the detection speed; Professional light source design, clear and uniform imaging, to ensure that no light spots are formed; Support the detection of various IC products, with online automatic product search function; The installation is simple and does not affect the work of the original production line; Compact structure, easy to operate, maintain and expand; High reliability, stable operation, suitable for various field operation conditions. The system is based on PC platform, which has strong expansibility. The machine vision software platform based on stereoscopic image can expand the needle measuring function, and can also be connected with SPC software. Visual image flatness detection system is being widely used, and it has been recognized by many electronic manufacturers because of its low price, strong practicability, simple operation, high precision and good stability.
