HI-RIS Image Capturer Type Babe


1. Type Babe

  1. We developed an automatic digital image capturing system (HI-RIS type babe) for multiple rice seedlings.
  2. Equipment composition of HI-RIS type babe is below.
  • The target for observation: 30 individual rice seedlings were grown in test tubes (diameter of 30 mm, a height of 200 mm).
  • The camera and the test tubes are both movable.
  • Size of the system: width 750 mm depth 660 mm height 600 mm.
  • Images are collected automatically from the germination of rice.
  • They are imaged over the course of one week.

3. Image analysis software

  1. We are developing image analysis software for collecting growth rates of rice seedlings from the image sequence, which is acquired by the image capturing system.
  2. The image viewer we developed can visualize sequential image data in a short movie.
  3. This tool supports measurement of the growth data from the image.

4. The effect of using this system

  1. Using serial image data, we could minimize errors due to uneven
    germination times between sibling plants.

5. Conclusion

  1. We have developed the "Hitachi Rice Imaging System (HI-RIS) type babe" that collects and evaluates image data for multiple rice seedlings.
  2. The image capturing system automatically collects image data for multiple rice seedlings.
  3. The growth image sequences are useful for obtaining detailed measurements of temporal and spatial analysis for seedling growth.
  4. We can minimize errors due to uneven germination times between sibling plants.
  5. Future work
