Embodiment 1

[0032] Such as figure 1 , figure 2 As shown, Embodiment 1: a real-time video image acquisition and processing system, including a photoelectric sensor module, a sampling processing module and a display module;

[0033] The sampling processing module sequentially samples, holds and processes the analog signals input by the photoelectric sensor module and sends them to the digital signal display module. Signal data processing and image display;

[0034] Data processing includes the processing of bit digital signals and the processing of group data composed of bit digital signals. The mean value of the inter-group transmission time slot of is used as the target value of the inter-group transmission time slot processing of the group data in the next data packet.

[0035] Preferably, wherein the sampling processing module performs multi-channel sampling processing on the incoming analog signal of the photoelectric sensor module, the sampling processing module also includes an i...

Embodiment 2

[0048] Embodiment 2, on the basis of embodiment 1, also includes the DSP processor that inserts described sampling processing module, DSP processor connects host computer, and described DSP processor includes RS422 serial port, network port communication interface, and described DSP The processor is connected to the host computer through Gigabit network and serial port, the host computer loads and monitors the processing data of the sampling processing module, the host computer monitors the temperature of the sampling processing module, and the host computer provides overheat protection for the sampling processing module , when the temperature upward trend of the sampling processing module approaches the preset temperature upper limit of the host computer, the host computer sends an early warning signal, and when the temperature of the sampling processing module reaches the preset temperature upper limit, the host computer disconnects the sampling processing module through the D...

Embodiment 3

[0049] Embodiment 3. On the basis of Embodiment 1, the display module further includes a signal processing module, and the signal processing module performs digital signal processing on the basis of the adjusted high-order digital signal and low-order digital signal to collect the data collected by the photoelectric sensor module. Simulation data reconstruction and image display.

Abstract

The invention discloses a real-time video image collection and processing system, relates to an information collection and processing system, and solves the problem of back jitter or non-uniform delay generated in the playing process of a video image. The device comprises a photoelectric sensor module, a sampling processing module and a display module, an adder is connected to the output end of a DAC and the input end of a first-stage ADC, the adder is connected to a second-stage ADC, the adder is used for subtracting an input signal of the first-stage ADC from a signal output by DAC residual voltage amplification, and the output signal of the first-stage ADC is obtained. And the second-stage ADC is used for digitally outputting the output signal of the adder as a low-order digital signal. According to the invention, the frequency of video image jitter back and non-uniform delay is reduced, the analog data of the photoelectric sensor is automatically processed, the imaging effect of the display screen is improved, and the playing quality and the playing comfort of the video or the image are improved.

Description

technical field [0001] The invention relates to an information collection and processing system, in particular to a real-time video image collection and processing system. Background technique [0002] With the continuous development of society, video image acquisition and processing technology plays a very important role in many industries, such as military, security monitoring, industrial vision and other fields, and all walks of life have more and more requirements for video image acquisition and processing technology. come higher. High-speed, real-time is one of the main development trends. At present, the development of video image acquisition and processing technology is mainly divided into two categories: one is to process video images through software based on the PC based on the relevant specific PCIe acquisition board; the other is to use related integrated hardware such as DSP, MCU, FPGA, etc. collect and process video images; [0003] Relatively speaking, the ...
