Thanks, I did try that earlier but over indented ever so slightly and kept getting errors, hence the handle, lol
Here is my working code, it works very well for testing right now, does anyone have any suggestions how I can make it better/faster? Like I said, working great, interested in hearing how I could improve it.
import sensor, image, time, math
threshold_index = 0 # 0 for red, 1 for green, 2 for blue
# Color Tracking Thresholds (L Min, L Max, A Min, A Max, B Min, B Max)
# The below thresholds track in general red/green/blue things. You may wish to tune them...
thresholds = [(30, 100, 15, 127, 15, 127), # generic_red_thresholds
(30, 100, -64, -8, -32, 32), # generic_green_thresholds
(0, 30, 0, 64, -128, 0)] # generic_blue_thresholds
sensor.skip_frames(time = 2000)
sensor.set_auto_gain(False) # must be turned off for color tracking
sensor.set_auto_whitebal(False) # must be turned off for color tracking
clock = time.clock()
# Only blobs that with more pixels than "pixel_threshold" and more area than "area_threshold" are
# returned by "find_blobs" below. Change "pixels_threshold" and "area_threshold" if you change the
# camera resolution. "merge=True" merges all overlapping blobs in the image.
img = sensor.snapshot()
for blob in img.find_blobs([thresholds[threshold_index]], pixels_threshold=200, area_threshold=200, merge=True):
# These values depend on the blob not being circular - otherwise they will be shaky.
if blob.elongation() > 0.5:
# These values are stable all the time.
img.draw_keypoints([(blob.cx(), blob.cy(), int(math.degrees(blob.rotation())))], size=20)
x = blob.cx()
y = blob.cy()
#Copy of Arduino map function
def map(x, in_min, in_max, out_min, out_max):
return int((x - in_min) * (out_max - out_min) / (in_max - in_min) + out_min)
xAxis= map(x,0,300, -15, 15)
print(xAxis, ",", yAxis)
