Setup for constructing a weed map

Abstract

The present invention relates to a device (100) for constructing the weed map. The device (100) includes an image recording unit (110; 110') comprising a camera (112) and a physiognomy tracing laser camera (114), an image processing and evaluating unit (120), a data memory unit (130) connected with the latter and a weed data base (135). The device (100) also includes a light source (160), and a position detecting unit (150) of the position refining element (154) which is used to more accurately confirm the space coordinate provided by the positioning element (152). The image recording unit (110; 110'), the position detecting unit (150) and light source (160) are connected with the image processing and evaluating unit (120) with data communication. Besides, the image processing and evaluating unit (120) is arranged with one or a plurality of control output (122 and 124), wherein one control output (124) can set data communication connecting with the control unit (190) of the independent weeding equipment.

Description

technical field [0001] The invention relates to a device for constructing a weed map, comprising an image recording unit with a video camera and a topography tracking laser camera, an image processing and evaluation unit, a data storage unit connected to the latter, and a weed database. Background technique [0002] German Patent Application No. 4132637A1 discloses a method and a device for achieving weed removal. According to this method, weeding is carried out according to the weed map. The weed map is constructed from the optical sensor and camera of the weeding apparatus discussed in this document, both of which are connected to a computer. During the recording of images, the instrument moves on a given path. The construction of the weed map is based solely on detecting the light reflected from the area scanned by the optical sensor and analyzing the recorded images. During said analysis, the current image is studied, and the parts appearing green are considered as we...

Problems solved by technology

Another disadvantage of the method of weed control discussed in said Hungarian patent application is that by means of this method the weed map can only be displayed at a certain time of day (e.g. throughout the day) and under suitable light conditions (e.g. for recording sufficient natural light for the image) to construct

[0004] A further disadvantage of the weeding device is that in some cases, for example, under conditions of rapidly changing light / dark effects or blurred images due to rapid movement of the instrument, each piece of information related to the weed species will only be can be determined indefinitely

However, this can be very disadvantageous when the elimination of weeds is carried out in a targeted manner with respect to the composition of the weed map, ie with species-specific herbicides
