Embodiment

[0027] Such as figure 1 As shown, the present invention includes a first CIS sensor, a second CIS sensor, a scan data processing system and a PC host. The first CIS sensor and the second CIS sensor are used to collect images, wherein one CIS sensor is used to collect the front image of the scanned object, and the other CIS sensor is used to collect the reverse image of the scanned object, and the two CIS sensors are simultaneously connected to the Scan data processing system connections. The scanning data processing system is connected with the PC host, and processes and transmits the image according to the instructions issued by the PC host. Specifically, the scanning data processing system includes an FPGA main control chip, and a first data conversion module connected to the FPGA main control chip, a second data conversion module, a first memory, a communication interface, a correction module, a USB module and An online debugging interface, and an onboard power supply mod...

Abstract

The invention discloses a double-sided scanner acquisition system based on an FPGA and a scanning and correction method thereof. The system comprises a scanning data processing system, a PC host, a first CIS sensor, a second CIS sensor, and a CIS transmission module which is connected with the first CIS sensor and the second CIS sensor simultaneously. The scanning data processing system comprises an FPGA master control chip, a first data conversion module, a second data conversion module, a first memory, a communication interface, a correction module and a USB module which are connected with the FPGA master control chip simultaneously, and an onboard power supply module. The first CIS sensor is connected with the first data conversion module. The second CIS sensor is connected with the second data conversion module. The CIS transmission module is connected with the communication interface. The PC host is connected with the USB module. The double-sided scanner acquisition system based on the FPGA is reasonable in design and convenient to use so that rapid scanning and imaging can be realized, images of two sides are displayed in one step, and thus the double-sided scanner acquisition system based the FPGA is suitable for popularization and application.

Description

technical field [0001] The invention relates to a scanner acquisition system, in particular to a calibration method for an FPGA-based double-sided scanner acquisition system. Background technique [0002] Most of the commonly used scanners on the market currently use single-chip microcomputers such as ARM as the main control chip. Although it has an advantage in cost, due to the limitations of the ARM chip itself and the unreasonable design of the scanner's own system, the scanning speed is slow, and it is difficult to meet the increasing pace of people's life and work. Moreover, existing scanners are generally in a single-sided scanning mode. For scanning objects with double-sided patterns, manual operations need to be performed twice, which does not meet the needs of intelligence. Contents of the invention [0003] The purpose of the present invention is to provide a calibration method for an FPGA-based double-sided scanner acquisition system, which mainly solves the pr...
