Embodiment

[0020] Such as figure 1 As shown, the present invention mainly consists of a single-chip microcomputer, an analog-to-digital conversion unit connected to the single-chip microcomputer, a storage and a display, a signal processing unit connected to the analog-to-digital conversion unit, and a signal collector connected to the signal processing unit.

[0021] Wherein the signal collector is used to collect the image signal of the scene, and the existing video camera can be used. The signal processing unit is used to process the analog signal output by the signal collector, so that the analog-to-digital conversion unit can better convert the analog signal. The analog-to-digital conversion unit can convert the analog signal into a digital signal, which is realized by using an ADS8515 analog-to-digital conversion chip, and the VIN pin of the ADS8515 analog-to-digital conversion chip is connected to the signal processing unit. The single-chip microcomputer realizes buffering of tra...

Abstract

The invention discloses a high precision image data acquisition and storage system based on low-pass filter. The high precision image data acquisition and storage system is characterized by mainly comprising a single chip microcomputer, an analog-to-digital conversion unit, a storage and a display which are connected with the single chip microcomputer respectively, a signal processing unit which is connected with the analog-to-digital conversion unit, and a signal collector which is connected with the signal processing unit. The high precision image data acquisition and storage system based on the low-pass filter provided by the invention can process an analog signal, so that the analog-to-digital conversion unit can convert the analog signal into a digital signal more quickly, thereby improving the data storage speed.

Description

technical field [0001] The present invention relates to the field of data processing, and specifically refers to a high-precision image data acquisition and storage system based on low-pass filter processing. Background technique [0002] At present, the image acquisition and storage system, as a conventional means of obtaining external scene information, has been widely used in various military and civilian fields. In the process of image acquisition and storage, it is usually necessary to convert the acquired analog signal into a digital signal and then store it. However, the conversion rate of the existing image acquisition and storage system to convert the acquired analog signal into a digital signal is relatively slow, thereby reducing the cost of data storage. speed. Contents of the invention [0003] The purpose of the present invention is to solve the defects of slow conversion rate and low data storage speed when the existing image acquisition and storage system ...
