METHOD FOR DETECTING PLANT GROWTH AMOUNT, PLANT SENSOR, AND FERTILIZING APPARATUS

A scan using a pulsed distance measuring light with two wavelengths of which reflectances are different with respect to a content of a nitrogen by a laser scanner, the two wavelengths are separated, lights are received, a distance measurement value and a light amount are detected for each pulsed dis...

Zusammenfassung:	A scan using a pulsed distance measuring light with two wavelengths of which reflectances are different with respect to a content of a nitrogen by a laser scanner, the two wavelengths are separated, lights are received, a distance measurement value and a light amount are detected for each pulsed distance measuring light and for each of the two wavelengths, a height of a crop is detected based on the distance measurement value, a received light amount ratio of the two wavelengths is detected, and a growth condition of the crop is detected based on the detected height and the received light amount ratio. ACQUIRE REFLECTED LIGHT DATA STP1 N o IS REFLECTED STEP 12 ELIMINATE D:ATA LIGHT AMOUNT WITHIN THRESHOLD VALUE? Yes ELIMINATE DATA CALCULATE HEIGHT STEP 13 is HEIGHT WITHIN THRESHOLD VALUE? Yes No CALCULATE GROWTH AMOUNT ELIMNATEDATAIS GROWTH AMOUNT WITHIN THRESHOLD VALUE? Yes DETECT DARK NOISE STEP 15 REMOVE OUTSIDE LIGHT NOISE IYes SAVE DATA STEP 16 TYes AS .ACQUISITION NUMBER STEP BEEN REACHED" No Yes COMPLETE NOISE COMPONENT REMOVAL
