Title of Dataset: CADillac 2. Author Information First Author Contact Information Name: Evgeny Toropov Institution: Carnegie Mellon University Address: Email: toropov.evgeny@gmail.com Corresponding Author Contact Information Name: Jose M. F. Moura Institution: Carnegie Mellon University Address: Dep. of Electrical and Computer Engineering, Carnegie Mellon University, Pittsburgh PA 15213-3890, USA Email: moura@ece.cmu.edu --------------------- DATA & FILE OVERVIEW --------------------- Before doing any work, please unpack blend.zip, examples.zip, and screenshots.zip. Directory of Files A. Filename: collection.json Short description: Metadata for each of the 3D models stored in a single json file. Version is of 2019.06.10. B. Filename template: blend.zip Short description: Unpack "blend.zip" first to get the folder "blend"! Each file blend/.blend is a 3D model of a car stored in the .blend format, that can be opened with Blender renderer. Each car model is centered in the ground plane, all four wheels on the ground, and is oriented along X-axis. The size of each model (in meters) is adjusted to match the size of that car in real life. C. Filename template: examples.zip Short description: First, unpack "examples.zip" to get the folder "examples"! Each file examples/.png is a sample rendered image of the 3D model. Image has a 1x1 meter grid on the ground plane. D. Filename template: screenshots.zip Short description: First, unpack "screenshots.zip" to get the folder "screenshots"! Each file screenshots/.png is a screenshot of the original model from 3D Warehouse website. ----------------------------------------- DATA DESCRIPTION FOR: collection.json ----------------------------------------- 1. Number of variables: 16 2. Number of rows: 1176 3. Missing data codes: null = Any missing data 4. Variable List A. Name: id Description: the id of the model in format %06d. Corresponds to the files blend/.blend, examples/.png, and screenshots/.png. B. Name: model_id Description: the id of the model as in 3D Warehouse. Together with collection_id, uniquely define the model. C. Name: collection_id Description: the id of the collection as in 3D Warehouse. Together with collection_id, uniquely define the model. D. Name: model_name Description: a short name of the model given by its author. E. Name: description Description: a verbose description of the model given by its author. F. Name: issue Description: an issue with the model, when processed by Blender. Note that renders of models with issues improved CNN performance. in our experiments triangles = A part of the model looks covered by triangular mesh, caused by an error in importing the model from Sketchup to Blender. no color = The information about color is missing, and the model is rendered as gray matte glass = The windshield and/or other glass is not transparent and rendered as matte light/dark. other = Other issues, such as general poor quality. G. Name: car_make Description: Car make, as manually parsed from model name and/or description. H. Name: car_year Description: Car year, as manually parsed from model name and/or description. I. Name: car_model Description: Car model, as manually parsed from model name and/or description. J. Name: length Description: Car length in meters, not counting the size of bumper guards, etc. Usually was found online for this particular car model. K. Name: width Description: Car width in meters, not counting side mirrors, etc. Usually was found online for this particular car model. L. Name: height Description: Car height in meters, not counting taxi cap, etc. Usually was found online for this particular car model. M. Name: color Description: Car color in cases when there is a dominant color. Car (1) with two or more dominant colors and (2) whose color is between two base colors have this field blank. red white black blue gray yellow green orange N. Name: domain Description: specified when one of the following domains can be attributed to the vehicle emergency = Police, ambulance, fire truck, etc. military = Military or special forces. fiction = Fictional vehicles, such as the car from "Back to the future" movie. taxi = Yellow taxi cars. O. Name: type Description: vehicle by type passenger = Small vehicles for individual use, such as sedans, hatchbacks, sport cars, SUVs, taxis, etc. truck = Commercial trucks, UHauls, pickups, etc. van = Commercial vans, normally with no windows. bus = In-city or inter-city buses, school buses. P. Name: url Description: url to the original model in 3D Warehouse. If absent, the model is no longer available online. -------------------------- METHODOLOGICAL INFORMATION -------------------------- 1. Software-specific information: A. Name: Sketchup with BlendUp plug-in. Additional Notes: Was used to export the model from .skp to .blend format. A. Name: Blender Version: 2.78 Product URL: https://www.blender.org Additional Notes: Blender was used to orient models in the ground plane, fix its size, fix the model position along Z-axis, and center the model in the ground plane. 2. Date of data collection: 2016-03-01 to 2018-08-30.
