RANSAC algorithm to use the vanishing point detection
Posted: Tue Aug 29, 2017 7:40 am
Hello,every one! Now I using the openmv3 board with stm32f7 mcu, I need to be used the RANSAC algorithm to detection the vanishing point.Follow the python script:
How to modified to suit the mpy platform.Thanks!
Code: Select all
import random
def run_ransac(data, estimate, is_inlier, sample_size, goal_inliers, max_iterations, stop_at_goal=True, random_seed=None):
best_ic = 0
best_model = None
random.seed(random_seed)
for i in xrange(max_iterations):
s = random.sample(data, int(sample_size))
m = estimate(s)
ic = 0
for j in xrange(len(data)):
if is_inlier(m, data[j]):
ic += 1
print s
print 'estimate:', m,
print '# inliers:', ic
if ic > best_ic:
best_ic = ic
best_model = m
if ic > goal_inliers and stop_at_goal:
break
print 'took iterations:', i+1, 'best model:', best_model, 'explains:', best_ic
return best_model, best_icHow to modified to suit the mpy platform.Thanks!
