PROTOLIDAR (version 0.1)

LIDAR_data: LIDAR data.

Description

LIDAR scan dataset in BBCH 65 (grapevine).Where x is width, y is height and z is front view or path of the tractor.

Usage

data(LIDAR_data)

Format

A data frame with 10108 observations on the following 3 variables.

V1

a numeric vector that represents x value or width

V2

a numeric vector that represents y value or height

V3

a numeric vector that represents z value or front view

Source

LIDAR scan in BBCH 65 stage.

Details

The laser scanner used was a LMS-200 model (Sick,Dusseldorf,Germany), a fully-automatic divergent laser scanner based on the measurement of time-of-flight (TOF) with an accurancy of 15 mm in a single shoot measurement and 5 mm standard deviation in a range upto 8m. The time between the transmission and the reception of the pulsed near-infrared laser beam is used to measure the distance between the scanner and the reflecting object surface. The laser beam is deflected by a rotating mirror turning at 4500 rpm, which results in a fan shaped scan pattern where the maximum scanning angle is 180 degree.
