Vehicle Category Recognition API - VehicleCRA (also known as vehicles categories detection API) is a cross browsers REST API which get a JSON input with a still photo (as base64 encoded string) or an url of the image and returns a JSON string which contains predictions with certain amount of probability (filtered for output with minimum 20%), bounding boxes of detected vehicle category(ies) with its top, left, width, height values and, if required, for each prediction, a boundingBoxPhoto as base64 encoded string of the detected vehicles categories. Also it outputs a base64 encoded string photo which is the original input photo with drawned bounding boxes upon it. For one still photo the API may return multiple predictions with different probability scores of detected vehicles categories. Our pricing packages count the predictions, so for one request, multiple predictions may be counted. We filter the results of predictions so we display only the predictions with a probability score higher than 20%. Of course, there are some limitations in order to get a higher accuracy. We recommend properly exposed, unobstructed JPEG photos at 1920x1080 (full HD resolution) where target vehicles may fill an important space in the input photo as you see in the example below. We do not store pictures. Also, the quality and the angles of the camera (30 degrees for side camera) are very important and it contribute to a higher detecting accuracy. It should have varifocal lenses, high shutter speed, good infrared lighting beam, full HD resolution.
Allthough this Vehicle Category Detection API (currently we do not offer a face vehicle category recognition sdk) is intended for software development and therefore developers, we have also here an vehicle category detector online application that may be used to check the input and output JSONs of the API.
The necessary steps are written below, basically for this real time vehicle category detection or recognition API you send an authorized POST request in JSON format to the API endpoint and you get as JSON response the output as described below through parameters and examples.
This Vehicles Categories Recognition API is useful for a large number of domains like: checking private entrances in parkings for restaurants, malls, close spaces, airports, bus stations, railway stations, traffic control for each category of vehicles etc. You own the commercial copyright of the resulted JSON with no additional fee meaning you may use it in your own apps for sale.
