Problems solved by technology

[0003] At present, most of the image acquisition cards on the market can only be used in some low-speed occasions for image acquisition of low-resolution cameras, and the real-time performance is poor. In the occasions where the image frame rate and resolution requirements are relatively high, satisfactory results cannot be obtained. Effect

Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0022] figure 1 Shows the first embodiment of the digital camera real-time acquisition system described in the present invention, this embodiment is designed for the digital camera of general output as TTL format data, comprises: digital camera 1, data bus 2, control line 3, PCI image acquisition card 4, PCI bus 9, computer 10. Wherein, the PCI image acquisition card 4 is a printed circuit board integrated with various chips and interfaces. 2 PROM8 is jointly composed.

[0023] The PCI image acquisition card 4 is directly inserted on the PCI slot of the computer 10; the digital camera 1 is connected with the PCI image acquisition card 4 by the data bus 2 and the control line 3: the digital camera 1 sends the image data captured by the data bus 2 to PCI image acquisition card 4, PCI image acquisition card 4 sends trigger pulse to digital camera 1 thr...

Abstract

This invention relates to a digital camera real-time collecting system, which belongs to data communication and process technology in electronic technology. The system comprises digital camera, PCI image collect card and computer, wherein the core part is the PCI image card, which applies high-velocity PCI interface chip, combined with high-velocity cache buffer and CPLD logical controlling chip, realizing high-velocity data real-time communicating between digital camera and PCI bus; by the invention, the computer has no problem of collecting large quantity data rapidly.

Description

technical field [0001] The invention belongs to the technical field of data transmission and processing, in particular to a real-time collection system of image data in a digital camera. Background technique [0002] With the continuous emergence of various new digital cameras, digital cameras have increasingly become detectors in systems such as real-time data acquisition, image processing, remote sensing monitoring, and automatic detection, and are widely used in civil, commercial, industrial, medical, scientific research and many other fields. But at the same time, the massive data output of the digital camera also puts forward higher requirements on the acquisition speed of the data acquisition system. [0003] At present, most of the image acquisition cards on the market can only be used in some low-speed occasions to collect images from low-resolution cameras, and the real-time performance is poor. In the occasions where the image frame rate and resolution requirement...
