Measurement Techniques for Correcting Images with Extended Depth of Field - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240029216 titled 'Measurement Techniques for Correcting Images with Extended Depth of Field
Simplified Explanation
The patent application describes a computer-implemented method for generating an extended depth of field image from a stack of focal images. The focal image stack consists of multiple images of a measurement object, each capturing a different region of the object's surface with a defined focal plane position. The method involves generating an initial image with an extended depth of field by combining the focal images. It also includes correcting imaging errors, such as distortion, in the initial image to generate a corrected image.
- The method involves receiving a stack of focal images of a measurement object.
- Each image in the stack captures a region of the object's surface with a different focal plane position.
- The focal plane positions of the images are different from each other.
- An initial image with an extended depth of field is generated based on the focal image stack.
- A set of imaging errors, including distortion, is corrected in the initial image.
- The corrected image is generated by applying the necessary corrections to the initial image.
Potential Applications:
- This technology can be used in various fields where accurate imaging of objects with different focal planes is required, such as microscopy, medical imaging, and industrial inspection.
- It can be applied in automated systems that require high-resolution imaging of objects with varying depths.
Problems Solved:
- Traditional imaging techniques often struggle to capture objects with different focal planes accurately.
- This technology solves the problem of limited depth of field by generating an extended depth of field image from a stack of focal images.
- It also addresses imaging errors, such as distortion, to improve the overall image quality.
Benefits:
- The method allows for the creation of high-quality images with an extended depth of field, providing a clearer and more comprehensive view of the measurement object.
- It enables accurate imaging of objects with varying depths, reducing the need for manual adjustments or multiple imaging attempts.
- The technology can improve the efficiency and accuracy of various applications, such as medical diagnoses, quality control, and scientific research.
Original Abstract Submitted
