In the current education system, college students often lack opportunities to directly participate in machine vision work. This article will explore the importance of machine vision learning and analyze the necessity of technical guidance and practical projects. And propose a comprehensive machine vision learning roadmap.
Machine vision and its applications in modern industry
Machine vision refers to the technology that uses computer vision technology to automatically analyze and understand images. It realizes the machine's "visual" recognition ability of image content through means such as digital image processing and pattern recognition. Machine vision technology is widely used in all aspects of modern industrial production, greatly improving the level of automation and becoming an important technical support in the Industry 4.0 era.
Challenges faced by college students in the field of machine vision
1. Theoretical knowledge is difficult. Machine vision involves multidisciplinary knowledge such as computer vision, pattern recognition, and image processing, and its theoretical foundation is complex. It requires college students to learn and master independently.
2. Practical ability needs to be improved. Machine vision requires practice to verify theory, but the lack of experimental conditions is a difficulty. You need to use open source platforms and data sets to practice.
3. The algorithm is difficult to implement. Algorithm support is required from image preprocessing, feature extraction to classification and recognition, and algorithm design and optimization are difficult.
4. Project development capabilities need to be developed. Machine vision projects need to integrate multi-disciplinary knowledge to complete and require project management capabilities.
5. Difficulty in integrating with industry. There is a gap between theory and practical application, and it is necessary to learn more about industrial standards and engineering practices. It is difficult to communicate with enterprises.
6. Competition pressure is high. There is a huge demand for talents in this field, and competition among peers at home and abroad is fierce. You need to improve your practical abilities and competitiveness through actual projects.
7. Soft power needs to be strengthened. It is necessary to improve communication and expression skills, learn new technology trends, and cultivate team spirit and other soft skills.
8. Lack of resources. Some universities have limited machine vision experimental conditions and insufficient resource sharing, which also increases the difficulty of learning.
Barriers for college students to participate in machine vision
1. Insufficient theoretical foundation. Machine vision involves multidisciplinary knowledge such as computer vision and deep learning. The setting of relevant theoretical basic courses can be added.
2. The coding ability is not strong. Machine vision requires writing a lot of code to implement algorithms. Programming training can be added, such as Python programming.
3. Lack of practical projects. Theoretical knowledge is difficult to translate into practical skills. Practical projects can be designed, such as image recognition, target detection, etc., to allow students to participate in actual development.
4. Data acquisition and processing are difficult. Collecting large amounts of labeled data is difficult. You can cooperate with enterprises to provide existing data sets; you can also explore how to use unlabeled data for self-learning.
5. Hardware limitations. Machine vision algorithm testing requires high-performance hardware such as GPU. You can use the virtual machine resources provided by the cloud computing platform.
6. Lack of instructor support. Professional teachers are needed to guide algorithm implementation details. Teacher study groups can be organized to jointly study and solve problems.
7. Out of touch with the industry. Difficulty understanding industrial needs. Corporate lectures can be added, students can be arranged to visit for internships, and students’ horizons can be enhanced.
The importance of technical guidance
1. Provide professional knowledge support. Machine vision involves multidisciplinary knowledge such as computer vision and deep learning. Technical guidance can explain relevant theoretical knowledge in a targeted manner based on students' learning levels.
2. Help solve practical problems. During the development process of practical projects, students will inevitably encounter various algorithm implementation or coding problems. Technical instructors can provide guidance on problems and help students find solutions.
3. Evaluate project quality. Technical directors have extensive project experience and can conduct quality assessments of student projects and point out deficiencies and areas for improvement.
4. Provide industry insights. Technical guidance goes deep into the industry and understands corporate demand trends, which can guide students in their learning direction and help them develop market vision and competitiveness.
5. Establish a learning support system. Technical guidance can organize online and offline learning exchange activities, create a learning atmosphere, and support students to help and learn from each other.
6. Help with employment guidance. According to students' ability level and interests, technical guidance can provide students with employment consultation and recommendations.
7. Stimulate learning motivation. Good technical guidance can stimulate students' desire to explore knowledge through examples and sharing.
The need for practical projects
1. Can help practice and apply theoretical knowledge. There is a lot of theoretical knowledge about machine vision. Practical projects can help students truly master and apply this knowledge and make up for the lack of theoretical teaching.
2. Can develop practical and problem-solving abilities. Machine vision projects often encounter various problems. Through practice, students can train their ability to analyze problems and solve problems independently.
3. Skill levels can be tested and improved. Completing a complete project requires the call and comprehensive use of a variety of skills. Through the project, students can test their existing skills and continuously improve their skill levels.
4. Can understand the actual needs of industry. Participating in practical projects allows students to understand the real needs of industry in machine vision and understand how the technology is applied to actual products.
5. Conducive to employment and entrepreneurship. Students with excellent project experience will have stronger competitiveness in the process of employment and entrepreneurship.
6. Can stimulate learning motivation. Completing meaningful projects can increase students' motivation and initiative in learning.
The role of machine vision skills training
1. Develop core skills. Machine vision skills training can help students master core skills in the field of machine vision, such as image processing, target detection, image classification, etc. These skills are the foundation that machine vision practitioners must master.
2. Improve practical operation capabilities. Through practical projects and case studies, students can truly master the use of various machine vision algorithms and tools, and improve their practical operation and problem-solving abilities.
3. Understand industrial needs. By participating in enterprise-level projects, students can better understand the real needs of industry in the field of machine vision and lay the foundation for future employment.
4. Promote employment. After mastering the core skills of machine vision, students will be more competitive in the job market for fresh graduates and will also be conducive to starting their own businesses.
5. Continuously improve yourself. Machine vision technology updates and iterates very quickly. It is imperative for practitioners to track technological progress and improve themselves through continuous learning.
6. Build motivation for learning. Practical skills training can well stimulate students' learning motivation and allow them to actively learn new knowledge and skills.
7. Lay the foundation for future learning. After mastering the basics, students will learn more advanced technologies more smoothly in the future, and it will also lay the foundation for deepening into a specific field.
