[Mission of the Role] 

• You will be responsible for the development and performance improvement of camera pose estimation pipelines from state-of-the-art static target calibration to real-time dynamic camera pose estimation methods. At your arrival, you will start by designing, developing, and implementing cutting-edge Target-based vehicle-to-camera extrinsic calibration algorithms and/or Targetless online, real-time vehicle-to-camera extrinsic calibration methods for automotive camera systems used in ADAS (Advanced Driver Assistance Systems) for StradVision’s FrontVision Product, SurroundVision Product, and MultiVision Product. This includes creating camera-based perception software for both mono cameras and multi-cameras, handling 2~3MP resolution cameras, and 8MP resolution cameras, and spanning the range from ADAS Level 2 to Level 4. Your work will directly contribute to enhancing the safety and performance of vehicles equipped with ADAS technology.

[Key Responsibilities]

• Algorithm Development
• Collaborate with senior/lead engineers to design, implement, and test camera calibration (camera pose estimation) algorithms and provide technical guidance on calibration methods and tools.
• Develop, implement, and optimize intrinsic and extrinsic camera calibration methods.
• Lead efforts in target-based extrinsic calibration and targetless on-road extrinsic calibration for vehicle systems.
• Design and refine calibration algorithms using tools such as Polynomial, Distortion, OpenCV, and other relevant frameworks.
• Research and implement advanced techniques for online and on-road calibration.
• Oversee the integration of calibration solutions into production and service environments.
• Define processes for first extrinsic calibration post-installation, considering scenarios like windshield or camera changes.
• Develop ego-motion compensation strategies to manage dynamic changes in extrinsic calibration angles (e.g., driving over bumps, suspension shifts).
• Optimize an algorithm and collaborate with cross-functional teams to ensure real-time performance on an embedded device under varying conditions.
• Testing and Validation Responsibilities
• Conduct rigorous testing and validation of camera pose estimation algorithms using real-world and simulated data.
• Identify and address algorithm performance issues and anomalies.
• Documentation
• Maintain detailed documentation of algorithms, methodologies, and test procedures.
• Create user manuals and documentation to facilitate algorithm integration by other teams.
• Collaboration
• Collaborate with cross-functional teams, including machine learning engineers, software integration engineers, hardware platform engineers, and quality assurance, to integrate camera pose estimation algorithms into ADAS systems.
• Participate in code reviews and knowledge-sharing sessions to foster a collaborative work environment.
• Mentoring and Technical Guidance
• Mentor and provide technical guidance to junior/entry engineers.

[Basic Qualifications] 

• Master’s or Ph.D. in Computer Science, Electrical Engineering, Robotics, or a related filed at least 5~7 years of industry experience
• Excellent oral/written communication skills and good teamwork spirit
• Excellent C/C++/Python programming skills
• Deep understanding of intrinsic/extrinsic calibration methods and 3D computer vision fundamentals such as Multiple-View Geometry.
• Experience with camera calibration with static target-based calibration, online camera calibration, or equivalent methods.
• Proficiency in tools and libraries like OpenCV, Polynomial models, and distortion correction techniques.
• Experience with on-road calibration techniques and dynamic compensation algorithms is a plus.

[Preferred Qualifications] 

• PhD in Computer Science or Electrical Engineering, Robotics, or a related filed with at least 7+ years of industry (ADAS, AD) experience, especially sensor calibration
• Excellent foundation in computer vision, and in particular 3D geometric computer vision including SLAM, Structure-from-motion, Multiple-view geometry, pose estimation
• Excellent mathematical fundamentals including linear algebra, computational geometry, vector calculus, probability theory, and numeric optimization
• Understanding of software development best practices, including coding standards, code reviews, design patterns, source control management, and test automation.
• Strong programming skills in Python, C++, or similar languages.
