Using PyLepton for Radiometric data from Lepton 3.5 + Raspberry Pi

[hwy...@gmail.com]

I have the lepton 3.5 connected to an Rpi 3 over i2c+spi. From python I'm using pylepton (Lepton3 branch) to get data. 

It returns a 160x120 array with values ranging from 0-29515. I'm simply converting the kelvin value by the following way, for example minimum temperature reading:

    min_t = (((a.min()-27315)/100.0)*1.8+32)

And so I'm getting temperature values. Is this the actual radiometric data I'm getting? If this is bad data and there is a different way to get radiometric data please let me know.  

Thanks!

The whole capture function I'm usingL

def capture(flip_v = False, device = "/dev/spidev1.0"):

  with Lepton3(device) as l: 

    a,_ = l.capture()
    min_t = (((a.min()-27315)/100.0)*1.8+32)
    max_t = ((a.max()-27315)/100.00)*1.8+32

  cv2.normalize(a, a, 0, 65535, cv2.NORM_MINMAX)
  np.right_shift(a, 8, a)
  return np.uint8(a), max_t, min_t

hi bro i was new to lepton 3.5 camera .. as well in python.. i need small help in lepton camera 3.5 using breadboard v1.4 ... using raspberry pi ... i need to take picture using this ... can u plz help me to modify code plz

Hi Joeis did you solve your problem?
