random_generate[source]

random_generate(offset_x, offset_y, point_num, area_length_x, area_length_y)

generate random points with mutiple parameters. Args: offset_x : offset for x's range. offset_y : offset for y's range. point_num : number of points to generate. area_length_x : x's range for generate random points. area_length_y : y's range for generate random points. Returns: rand_point_x : list of random points' x coordinate. rand_point_y : list of random points' y coordinate.

sub_random_generate[source]

sub_random_generate(offset_x, offset_y, point_num, area_length_x, area_length_y, sub_area_num, sub_offset_x, sub_offset_y)

generate random points with mutiple parameters, including sub_area_num and sub_offset. Args : offset_x : offset for x's range. offset_y : offset for y's range. point_num : number of points to generate. area_length_x : x's range for generate random points. area_length_y : y's range for generate random points. sub_area_num : sub_offset_x : sub_offset_y : Returns : rand_point_x : list of random points' x coordinate. rand_point_y : list of random points' y coordinate. Outputs : output_point.txt : random points' x and y coordinate.

draw_line[source]

draw_line(sub_area_num, x_min, x_increment, y_min, y_max)

draw straight line in a plot. Args: sub_area_num : number of area that separated by lines. x_min : where the line starts. x_increment : distance of two lines. y_min : line's y lower coordinate. y_max : line's y upper coordinate.

Testing example

we will move to 'data' directory to start all examples, this directory have been added to '.gitignoe' , so is convenient to test in local and light in cloud

import matplotlib.pyplot as plt

cd data

/home/arg/arg_robotics_tools/data

random_generater( )

generate random points and save it in rand_point_x, rand_point_y.

                                             area_length_y = 50)

plot the lines and points that just generate.
