AI is Revolutionizing Crystal Inspection In the Chemical Industry  

Feb, 2025. Vancouver 

In the modern chemical industry, crystal inspection has a crucial impact on the quality and performance of products. However, traditional manual detection methods are not only inefficient, but also susceptible to subjective judgment, resulting in insufficient accuracy. DaoAI developed an efficient and automated crystal inspection system for a leading German chemical company with a history of 140 years. The company is mainly engaged in the research and development, production and sales of chemical products, which are widely used in plastics, rubber, coatings, medicine and other fields. They have been looking for advanced technologies and solutions to improve product quality and production efficiency. 

Challenge: Bottlenecks in Manual Detection 

In chemical production, the shape, particle size and distribution of crystals directly affect product performance and quality. However, there are many challenges with traditional manual inspection methods: 

• Inefficient: Relying on the human eye to observe and measure, the entire process is insufficient and time-consuming. 
• Limited accuracy: Manual interpretation is easily affected by subjective factors, and it is difficult to ensure consistency. 
• High cost: The training and input cost of professional and technical personnel is high.  

To overcome these problems, DaoAI provides an automated inspection solution based on AI vision technology.  

Solution: AI-driven Intelligent Inspection System 

The AI crystal inspection system, developed using DaoAI World, utilizes an auto-segmentation model and customized algorithms to accurately analyze crystal characteristics. It focuses on the following key points: 

• Crystal coverage detection: Through image analyzing technology, the distribution range of crystals on the surface of the material is automatically calculated to ensure production standards are met. 
• Crystallization feature analysis: The AI model can distinguish between three different crystalline morphologies (lumpy, flake, and hybrid) to provide more in-depth material analysis. 
• Average particle size calculation: Through high-precision image processing, the crystal size is automatically measured to ensure that the particle size distribution meets the product requirements. 

These technologies not only improve the inspection efficiency, but also reduce the rate of defective products in the production process and ensure consistent product quality. 

High-Resolution and Intelligent Annotation 

The accuracy of an AI model relies on high-quality data annotation. In order to improve the detection accuracy, we adopted a multi-resolution sample strategy and a high-precision sample strategy 

• 500x microscopic image: Mainly used to calculate coverage and crystallization characteristics, ensuring accuracy and efficiency. 
  
• Additional annotation of 1k and 2k resolution samples for auxiliary training and validation: To further improve the accuracy and performance of the model, we additionally annotated 1k and 2k resolution samples as auxiliary training and validation data. 
• 2K samples for accurate grain size and size distribution: We prioritize using 2K high-resolution samples. These high-resolution images provide clearer and more detailed crystal structures, enabling the AI model to measure grain size and distribution more accurately. 

Verification of results: AI vs. Manual detection 

In multiple tests and experiments, the AI crystal inspection system has demonstrated accuracy close to that of manual inspection, while significantly outperforming in efficiency: 

• Coverage Testing: While manual inspection can only provide a rough, subjective estimate of coverage, AI offers a quantitative result. Providing accurate data for measurement and analysis.
• Crystal Type Analysis: The model accurately classifies flaky crystals, matching the results of manual inspection. 
• Average Grain Size Measurement: Manual inspection cannot provide precise measurements and is time-consuming. AI’s calculated results have minimal error compared to standard samples, meeting production requirements. 

In addition, the system can generate detailed statistical reports, helping businesses monitor the production process and optimize operations to achieve higher production quality standards.
