ProcessedPiRecorder

A multiprocessed class of picamera for video recording.

Saves timestamped images to a BigTif. Can handle stereopi videostream.

Installation

  pip3 install ProcessedPiRecorder

Requires

• tifffile - 2019.7.26
• picamera - 1.13
• opencv-contrib-python - 3.4.4.19
• numpy - 1.17.0

Basic Usage

You have to initialize the recorder and then tell it when to start recording.

Initialize:

  myRecorder = ProcessedPiRecorder(x_resolution = , y_resolution = , framerate = , 
                                   rec_length = , tif_path = ,
                                   stereo=False, scale_factor=1, timestamp=True)

• (x_resolution, y_resolution) - pixel dimensions to acquired by the sensor(s)
• framerate - desired framerate in Hz
• rec_length - number of seconds to record
• tif_path - file to the output big tif file
• stereo - if True, hflip=True, stereo_mode='side-by-side', stereo_decimate=False
• scale_factor - sets the resize parameter at resolultion*scale_factor
• timestamp - if True, all frames are timestapmed at aquisition

Run

  myRecorder.recordVid()
