Description
Technical field
The present invention relates to a kind of real-time reading devices of hand-held graduated cylinder liquid level, belong to calibration data and read technical field.
Background technology
In some laboratories, clinic, hospitals and other places, graduated cylinder as a kind of instrument of most basic measurement liquid volume,
Its use is still very universal.But usually we are the scales for going to read liquid level in graduated cylinder with eyes, although for graduated cylinder
We are more skilled for the reading of scale, but when we need repeatedly to read the scale of graduated cylinder, can make us
Eyes generate fatigue, and the number that human eye is read out sometimes is nor very accurate.In order to solve these problems, it is necessary to design one
The easy real-time reading device of graduated cylinder liquid level of kind.
Invention content
The technical problem to be solved by the present invention is to：A kind of real-time reading device of hand-held graduated cylinder liquid level is provided, it can be accurately fast
Fast reading taken amount cylinder calibration data, with overcome the deficiencies in the prior art.
The technical scheme is that：A kind of real-time reading device of hand-held graduated cylinder liquid level, including ontology and handle, handle
It is connected to body lower part, the image set module for acquiring image is equipped at the back side of ontology, display is equipped in the front of ontology
Screen and button, are equipped with processor and power module, wherein the signal output end and processor of image capture module in ontology
Signal input part connection, the signal input part of the signal output end of processor and display screen connects, the signal output end of button
It is connect with the signal input part of processor, power module provides power supply for the normal work of device.
Memory module is additionally provided in ontology, memory module is connect with processor, for storing the data read.
It is equipped with LED light in ontology front, LED light is connect with processor, is used for display working condition.
Described image acquisition module is ccd image sensor.
The beneficial effects of the invention are as follows：The present invention by image capture module carries out the acquisition of image data and by acquisition
Data are stored to memory module, are analyzed the image data of acquisition by processor module, it is corresponding to find out graduated cylinder liquid level line
Numerical value, and show on a display screen.Compared with artificial reading manner, the present invention has reading speed fast, and accuracy is high, just
In record, it is highly practical the advantages that.

State and normal operating conditions and reading abnormality.
The present invention operation principle be：As shown in figure 4, by 6 horizontal aligument cylinder scale size one side of image capture module,
And graduated cylinder liquid level line image is acquired, processor carries out scale signal extraction, amplification, the extraction of scale signal to the image received
It is then to be completed by gaussian pyramid and time-domain filtering, the amplification of scale signal is then that the scale interval signal that will be extracted carries out
Amplification obtains final scale value finally by the calculating of image reorganization and scale signal.
The above content is a further detailed description of the present invention in conjunction with specific preferred embodiments, and it cannot be said that
The specific implementation of the present invention is confined to these explanations.For those of ordinary skill in the art to which the present invention belongs, exist
Under the premise of not departing from present inventive concept, a number of simple deductions or replacements can also be made, all shall be regarded as belonging to the present invention's
Protection domain.
