Problems solved by technology

Most of the existing image acquisition systems rely on electronic computers and video acquisition cards. The acquisition system is not only large in size and high in cost, but also has poor imaging quality and is sensitive to the external environment. It is difficult to meet the needs of efficient and convenient testing.

Embodiment 3

[0074] Further, on the basis of the above embodiments, the following describes the image acquisition system in detail according to the design of the PCB board.

[0075] When designing printed circuit boards (PCB boards), first classify the system functions, and design according to the core ideas of system functions, design risks, assembly reliability, and cheapness. The circuit PCB of this system is mainly composed of four parts, ARM core card, communication interface card, FPGA card, interaction and delay protection card, and each card has an independent power supply system, and its power input terminal is the same terminal. Using the above-mentioned design scheme, on the one hand, each card can be independently developed and verified, and on the other hand, it can prevent the failure of the power system of a certain card from affecting other cards and reduce the development risk.

[0076] Specifically, see Figure 7 , Figure 7 A schematic design diagram of a communication...

Description

technical field [0001] The invention belongs to the field of photoelectric instruments, in particular to an image acquisition system. Background technique [0002] Image acquisition systems based on high-performance computers appeared in the 1960s. Most of the acquisition systems at that time were dedicated image acquisition and processing systems with a narrow application range, such as the MODEL-70 and MODEL-75 designed by the US I2S company. The research on the image acquisition system started relatively late, and the main representative is the TS79 image acquisition and processing system of Tsinghua University. At present, the image acquisition system has gradually developed towards generalization. This kind of image acquisition system uses the general high-performance interface of the computer, designs acquisition cards with different interface forms, and then realizes the acquisition of image data with the help of the powerful processing ability of the computer. [00...
