Abstract

The invention belongs to the technical field of rapid and accurate detection of spot positions, and relates to a system and method for detecting spots positions based on FPGA. The present invention uses FPGA as the main control chip, uses the hardware description language to model the scene, and maps the hardware model to the development board through the FPGA development tool to complete various timing requirements such as signal acquisition, analog-to-digital conversion, result judgment, and motor control. , cooperate with the image acquisition card, host computer and high-precision three-axis stepping motor to realize position detection. Under the premise of meeting market requirements, it has the advantages of high detection accuracy, fast processing speed, strong anti-interference ability, and stable operation, which reduces the production cost. The cost is improved, the working environment is improved, and the production cycle is shortened.

Description

technical field

[0001] The invention belongs to the technical field of rapid and accurate detection of spot positions, and relates to a system and method for detecting spots positions based on FPGA. Background technique

[0002] With the continuous development of precision industry and missile guidance and other fields, spot position detection has been greatly welcomed in the fields of industrial precision inspection and missile guidance. requirements.

[0003] Chen Du et al. proposed in "Four-quadrant Infrared Detector Signal Processing System" (Science Technology and Engineering, 2006 (05): 611-615) that there are many kinds of spot detectors, mainly charge-coupled devices, position sensitive devices and four-quadrant detectors. Among them, the most commonly used four-quadrant detector is a photodetector device formed by arranging four photodetectors with exactly the same performance according to the requirements of rectangular coordinates. It is a multi-component non-im...
