Thus resulting in high price and inconvenient expansion.

Examples 1,

As shown in fig. 13, an embodiment of the present invention provides a chemical composition analysis system, including: image acquisition device, intelligent terminal to and server. The intelligent terminal can acquire the image information of the image acquisition device and interact with the server. Specifically, the method comprises the following steps:

and the image acquisition device is used for placing the solution to be detected.

And the intelligent terminal is coupled to the image acquisition device, can acquire the image information of the solution to be detected placed in the image acquisition device, and sends a detection request to the server. The detection request includes at least image information.

And the server is used for calculating the element content information of the solution to be detected according to the image information and sending the element content information to the intelligent terminal.

It should be noted that, as technology advances, the network speed is faster and faster, and a 4G network only needs several seconds to transmit a picture. Thus, a distributed chemical composition analysis system is realized.

In this embodiment, the image acquisition device and the intelligent terminal are local and used for acquiring image information of the solution to be measured. The server is a cloud server, and data are transmitted between the intelligent terminal and the cloud server through the Internet. The image acquisition and the image analysis can be completed in different places, so that the image acquisition device is more portable, and the practicability of the chemical component analysis system is greatly improved. And the server or the image acquisition device can be upgraded independently, so that the expansibility of the chemical component analysis system is greatly improved, the upgrading cost of the system is greatly reduced, and the method has good practical significance.

And the image is shot by the intelligent terminal and then is sent to the server for analysis, and the image is sent to the intelligent terminal for display after the server analyzes. A server can serve a plurality of intelligent terminals, namely, a user only needs to purchase an image acquisition device, and chemical composition analysis can be realized by using a server of a manufacturer, so that the purchase and use cost of the user is greatly reduced, and the server has good practical significance.

It should be noted that the intelligent terminal may be an intelligent device capable of capturing images and interacting information with the server, such as a mobile phone, a tablet, or a computer externally connected with a camera. The image acquisition device is a special container capable of providing external light isolation and providing stable light.

On the basis of the above-described embodiments, in an alternative embodiment of the present invention,

The image information is original pictures obtained by shooting of the intelligent terminal or cutting pictures of only the solution to be detected.

It can be understood that the obtaining of the composition information of the solution to be tested mainly comprises the following four steps:

1. adding chemical color developing agent into the detected target chemical component solution (i.e. solution to be detected), and placing in a container (i.e. image acquisition device)

2. The intelligent terminal shoots the liquid in the container through the camera and uploads the shot picture to the server

3. The server receives the picture containing the solution to be detected, the picture is processed to obtain a chemical component content result,

4. the server side returns the content of the chemical elements in the solution to the intelligent terminal

and receiving the image information, and acquiring element content information of the solution to be detected corresponding to the image information according to a preset component analysis model. Wherein, the component analysis model is established according to the Lambert-beer law.

In particular, the composition model may be a generic composition analysis model. Preferably, the preset component analysis model is established according to a blank control image and a plurality of standard control solution images with different solution solubilities by the Lambertian law. And establishing a model through the Lambert-beer law, and calculating the element content of the solution to be detected corresponding to the image information, so that the quantitative accuracy is higher.

On the basis of the above embodiment, in a preferred embodiment of the present invention, the detection request further includes a target identifier. The target identification is a user identification or a type identification of the target solution. The server is specifically configured to:

and acquiring a corresponding preset component analysis model according to the target identification. The preset component analysis model is established according to the Lambert-beer law and at least one contrast image. Wherein, the contrast image comprises an image of a container which is collected by the intelligent terminal and is not filled with solution and/or an image of a container filled with standard solution.

Specifically, the intelligent terminal sends the image information of the solution to be detected to the server and simultaneously sends a target identifier, and the server carries out depth adaptation of the detection algorithm by verifying the target identifier. The depth adaptation may be to remove contaminants, interference colors, or suspended matter, etc. from the image information of the solution to be measured by an algorithm. The algorithm may be median filtering, binarization, mean filtering, etc.

The target identifier may be a user identifier (account identifier) for the server to perform authentication and login operations on the user terminal, and obtain a stored preset component analysis model from the system.

The target identification can also be a type identification of the solution to be detected, namely, when the user uploads the image, the type of the solution to be detected, such as nickel solution, is manually selected on the intelligent terminal, and then the server analyzes the solution according to a special component analysis model corresponding to the target identification so as to obtain a faster and more accurate analysis result.

On the basis of the foregoing embodiment, in another optional embodiment of the present invention, the server is specifically configured to:

The server is thus provided with a dedicated component analysis model building function. The user needs to upload the blank contrast image and the standard contrast image of the solution to be detected while uploading the image information of the solution to be detected.

The server collects a plurality of sampling information according to the blank contrast image and the standard contrast image of the solution to be detected, and establishes a special component analysis model according to the sampling information. Then, the special component analysis model is used for analyzing the image information of the solution to be detected so as to obtain a more accurate analysis result, and the method has good practical significance.
