Parameters and modes of ground photography of crops to determine weed location
In the field conditions, in a set of technical experiments on industrial grain crops, the optical camera system along with a positioning system was tested on ground carrier to assess the contamination of crops by weed plants. To choose optimum parameters of photography that ensure reliable determination of the presence and location of weeds in crops, photography scenarios were implemented at different velocities of the unit and at different camera mount angles. The necessary resolution and quality of photo images was achieved with the camera mount angle values set to 30-45о, the unit movement velocity was 13-15 km/h and the filming frequency was 4 frames per second. The presence of weeds was visually determined with high reliability in the obtained images of the crops. The images with the achieved characteristics (quality and resolution) make feasible the further recognition of target objects in automatic mode based on the developed technologies with artificial intelligence usage.
