Harry's Toolbox

Harry's Toolbox is a collection of lightweight Python utilities. Each designed to simplify a basic task, such as calculating the framerate of a video feed.

FPS Counter

The FPS Counter module is designed to simplify the process of monitoring the framerate of a video feed.

After creating an instance of the FPSCounter class, the module works by expanding "to string" function __str__ to measure the time since the __str__ function was last called, and uses this time difference to calculate the frame rate.

Example Usage

import time

from harrys_toolbox import FPSCounter

fps = FPSCounter()

while True:

    # Prints out the framerate of the video
    print(fps)

    # Delay to represent the processing time of each frame.
    time.sleep(0.01)

Terminal Output

FPS: 96.02

Millis

Returns the number of milliseconds since the module was imported, as an integer. This function is based on the Arduino function of the same name.

Example Usage

import time
from harrys_toolbox import millis

while True:
    print(millis())

    time.sleep(1)

Terminal Output

0
1001
2001
3002
