ROBOTIC SURVEYING OF FRUIT PLANTS |
| 摘要 |
A method of machine vision includes identifying contours of fruits in a first image and a second image and performing two-way matching of contours to identify pairs of matched contours, each pair comprising a respective first contour in the first image that matches a respective second contour in the second image. For each pair of matched contours, a respective affine transformation that transforms points in the respective second contour to points in the respective first contour is identified. The second image is mapped to the first image using the affine transformations to form a composite image and the number of fruits in the composite image is counted. |

1. A method of machine vision, the method comprising:
identifying contours of fruits in a first image and a second image; performing two-way matching of contours to identify pairs of matched contours, each pair comprising a respective first contour in the first image that matches a respective second contour in the second image; for each pair of matched contours, identifying a respective affine transformation that transforms points in the respective second contour to points in the respective first contour; mapping the second image to the first image using the affine transformations to form a composite image; and counting fruits in the composite image. |
