Title: Experiments with intrarow weed control with a camera


1
Experiments with intra-row weed control with a
camera
  • Pieter Bleeker

2
Content
  • Introduction
  • Localisation of crop plant position by a light
    sencor
  • Localisation of crop plant position by a camera
  • Future ??
  • Can a camera locate small onion plants
  • Questions
  • Statement

3
Introduction
  • Why new equipment for intra-row weeding ?
  • The availably equipment cannot kill all the
    intra-row weeds, special for sow crops
  • To reduce hand labour.
  • In the future in a lot of crops availability of
    herbicides will be reducing.

summary
  • Simple
  • Low cost
  • For crops like lettuce good
  • --
  • Capacity (max. 3 km/h)
  • Changing row distances
  • Weed plants must be smaller than the crop

8
Camera system
  • Camera system can detect the crop plant and send
    a signal to a hoe

9
Localisation of crop plant position
Shape and colour are important to locate the crop
plant

11
The effect of the intra-row hoe
12
Future ??
  • Changed sowing or planting systems.
  • Other intra-row weed killing systems.
  • Burning
  • Water cutting
  • Laser
  • And so on

13
Different way of sowing onions
  • Now 4 or 5 rows on a 1.5 meter bed
    every 3 4 cm one seed.
  • Planting row distance 30 or 50 cm.
    6 7 seeds on one pot
  • New, clusters also 4 or 5 rows on 1.5 meter bed
    5 seeds on a spot and
    between the spots 15 20
    cm.

15
First experiments with intra-row burning
16
Questions ??
  • How to combine techniques and knowledge, to make
    a big step forward?
  • What is the best way for intra-row
    weeding?Hoeing, burning, water cutting, laser
    etc?
  • Is it worth while to combine this kind of systems
    with a autonomous vehicle?

17
Future ?? Mechanical weed control without any
person ???
18
Statement
  • In 5 till 10 years it will be possible to
    pick-out weed plants that stand closer than one
    centimeter from the crop plant.
