Finding Datasets For Computer Vision

Hello! I’m a senior electronics engineering student. My friend trying to make a blind-assistant that helps blind people to differentiate same form-objects as like Coca-Cola vs Sprite. He design a hardware with esp8266 and uses a cloud for storing datasets. We create a dataset with taking photos of cokes however its hard to creating for all stuff. Is there any solution or resource for finding daily life datasets? We had dive a lot of open datasets CIFAR, Berkley, Kaggle, COCO, MNIST but we required 224×224 pixels for our ML model.
