Abstract
An object sensor and method using pulsed laser range imaging technology is adapted for controlling an agricultural spraying system. A single laser sensor employs a continuously scanned pulsed laser transmitter and optical receiver to determine the presence or absence of foliage in predetermined spray zones to selectively control spraying only in those spray zones where foliage has been sensed. Range and distance data are also collected and stored in a microprocessor for use in determining the appropriate zones requiring spraying.
