Data collection system processing method and data collection system

Abstract

The invention discloses a data collection system processing method and a data collection system and relates to the field of data collection technology. The data collection system processing method comprises the steps that a first chip and a second chip collect information image data of a user; the collected image data is transmitted to a processing unit; and the processing unit sequentially processes the image data collected by the two chips, and the processed image data is subjected to splicing processing to form an information image. According to the data collection system processing method and the data collection system, the two small area-array chips are spliced into a large area-array chip, the image data is collected respectively, processed in a centralized mode and spliced into the data collection image, therefore, the user does not need to design a large area-array chip after designing the small area-array chips, design cost and model opening cost are reduced, and model opening time is shortened.

Description

technical field [0001] The invention relates to the technical field of data acquisition, in particular to a data acquisition system processing method and a data acquisition system. Background technique [0002] In order to distinguish information, current data collectors can be mainly divided into optical data collectors and capacitive data collectors. Among them, the data acquisition chip of the capacitive data collector generally includes a chip of a small area array and a chip of a large area array. [0003] Large area array chips are suitable for most data collectors on the market, which require accurate identification and fewer input times. The chip algorithm requires less code and less calculation. When storing multiple information, data can be extracted in time for comparison. The chip of the small area array is suitable for mobile terminals such as mobile phones for accurate identification. Because the algorithm of the chip requires accuracy and the amount of code i...

AI Technical Summary

Problems solved by technology

The chip of the small area array is suitable for mobile terminals such as mobile phones for accurate identification. Because the algorithm of the chip requires precision and the amount of code is large, it cannot support multiple information, and the algorithm cannot extract enough feature values, that is, the small area array The chip is not suitable for most of the data collectors on the market that do not require high precision, so the chip of the small area array and the chip of the large area array cannot replace each other

However, since the chip design and mold opening of small area array chips are different from those of large area array chips, the required tape-out cost will increase, and the cost and time of mold opening will also increase.
