Device and method for analyzing transmission type charge-coupled device (CCD) imaged image

Abstract

The invention discloses a device and a method for analyzing a transmission type charge-coupled device (CCD) imaged image. The device comprises a sample placing module, an image acquisition module and a control module, wherein the sample placing module comprises a porous liquid sample transparent vessel and a bracket; the image acquisition module comprises a light emitting diode (LED) uniform transmission light source module, an optical imaging module and a photoelectric conversion module; and the control module comprises a master control module, a computer, a bracket driver module and a data transmission module. The method comprises the following steps that: the image acquisition module and the control module in the device are reset; the porous liquid sample transparent vessel filled withexperiment samples is fixedly arranged in the bracket; the master control module controls the bracket to pass through a position between the LED uniform transmission light source module and the optical imaging module at a constant speed through the bracket driver module; and the image is acquired by the image acquisition modules, transmitted to the computer by the data transmission module and analyzed. The device can fast image a plurality of liquid samples at one time, can be smoothly operated and has high recognition accuracy rate.

Description

technical field [0001] The invention relates to the field of analysis and identification of liquid samples, in particular to a transmission type CCD imaging image analysis device and method. Background technique [0002] At present, the photographing method is mostly used for graphic and color recognition of liquid samples. This method uses a close-focus high-pixel camera to take pictures of the samples one by one, and then transfers the pictures to the computer for comparison with the pre-stored standard pictures, so as to make a judgment on the samples. This method has the following disadvantages: (1) the speed is too slow when identifying a large number of liquid samples, and cannot be used for liquid sample identification with strong timeliness; (2) when the camera is transferred from one sample to another for shooting It is easy to produce positioning errors, thereby reducing the correct rate of recognition; (3) Every time the camera starts and stops, it will produce a...

Problems solved by technology

This method has the following disadvantages: (1) the speed is too slow when identifying a large number of liquid samples, and cannot be used for liquid sample identification with strong timeliness; (2) when the camera is transferred from one sample to another for shooting It is easy to generate positioning errors, thereby reducing the accuracy of recognition; (3) Every time the camera starts and stops, it will produce an impact, which will cause the liquid sample to oscillate, which will obviously damage the original image of the sample

[0003] Moreover, although the existing camera or digital camera can take pictures of multiple liquid samples at one time, obtaining a high-definition image without deformation requires a large focal length and high resolution, which is actually not feasible

Existing scanners can also image at one time, but because they are designed according to planar graphics, they are not suitable for stereoscopic imaging with a certain depth, and the way that the scanning head is on the bottom and the sample is on the top cannot be used for liquid imaging.
