pydicamsdk

A wrapper for the pco sensicam/dicam SDK

This class is a Python wrapper for the Sensicam SDK of pco AG, Germany and provides an API to handle an pco camera in python. It is tested and used with a Dicam Pro.

class sensicam

The constructor automatically intialized the PCI board and allocates hdriver accordingly. The class sensicam is used for the control of the camera

class imgBuf

The class imgBuf is the object-oriented approach for the image buffers and aims to have buffer management within python.

Example

import dicamsdk

board = 0
with dicamsdk.sensicam(board) as pcoCam:
    # Setup a the COC
    gain = 0     # normal analog gain
    submode = 0  # sequential, busy out
    roixmin = 1
    roixmax = 1
    roiymin = 1
    roiymax = 1
    hbin = 1
    vbin = 1
    # Table values:
    phosphordecay, mcpgain, trigger, loops = 100, 999, 0, 1
    imageTime1 = [0, 1000, 0, 300]
    table = pcoCam.dicamTableGen(phosphordecay, mcpgain, trigger, loops,
                                 imageTime1)
    camera_type = 5     # For dicam pro
    pcoCam.setCoc(gain, camera_type, submode, roixmin, roixmax, roiymin,
                  roiymax, hbin, vbin, table)
    print("COC loaded")
    # Get sizes and allocate buffer
    pcoCam.getSizes()
    # Initialize a buffer
    curBuf = dicamsdk.imgBuf()
    pcoCam.allocateBuffer(curBuf)
    pcoCam.mapBuffer(curBuf)
    pcoCam.setBufferEvent(curBuf)
    # Set camera to state RUN
    pcoCam.runCoc()
    # Acquire and show the image
    pcoCam.readImage12bit(curBuf)
    im, npImage = pcoCam.getImageFromBuffer(curBuf)
    im.show()
    # Convert the rawImage to 8 bit
    exportImage = im.convert("L")
    exportImage.save("test.png")
    # Stop the camera, only necessary in continuous trigger mode.
    # pcoCam.stopCoc()
    # Free all buffers and close the camera
    pcoCam.freeBuffer(curBuf)
print("Card closed.")
