######## Image Object Detection Using Tensorflow-trained Classifier ######### # # Author: Evan Juras # Date: 1/15/18 # Description: # This program uses a TensorFlow-trained classifier to perform object detection. # It loads the classifier uses it to perform object detection on an image. # It draws boxes and scores around the objects of interest in the image. ## Some of the code is copied from Google's example at ## https://github.com/tensorflow/models/blob/master/research/object_detection/object_detection_tutorial.ipynb ## and some is copied from Dat Tran's example at ## https://github.com/datitran/object_detector_app/blob/master/object_detection_app.py ## but I changed it to make it more understandable to me. # Import packages import os import cv2 import numpy as np import tensorflow as tf import sys # This is needed since the notebook is stored in the object_detection folder. sys.path.append("..") # Import utilites from utils import label_map_util from utils import visualization_utils as vis_util # Name of the directory containing the object detection module we're using MODEL_NAME = 'inference_graph' IMAGE_NAME = 'test1.jpg' # Grab path to current working directory CWD_PATH = os.getcwd() # Path to frozen detection graph .pb file, which contains the model that is used # for object detection.

""" This script will modulate the blinky lights using the following algorithm: 1) uses user-provided location to obtain row of pixel data from bathy image 2) samples a 'number of LEDs' number of pixels from that row 3) shifts the sampled row data to center it at the location specified by user 4) displays resulting pixels on Blinky Tape 5) shifts next row by a given latitude, also specified by user 6) sleeps for user-specified period of time Uses the following arguments: -l/--location: tuple Location of the user in tuple(lat, lon). This represents the center of the LED strip. Defaults to (0, 0) -u/--update-interval: int Update interval of the script, in minutes. Defaults to 10. -p/--port: str Serial port of the BlinkyLight (e.g., 'ttyAMA0', 'COM3'). Defaults to 'COM5'. -d/--delta_latitude: int Vertical change in latitude every update rate. May be 0, but this will result in a never-changing LEDs. -i/--image: str Name of the PNG image that contains the color coded pathymetric data.
