Patent number: 11908095Abstract: The present technology is directed to presenting a 3-D representation of an object, which is captured in a 2-D image of the object in an environment in a 3-D simulation of the environment. The present technology can receive 3-D data representing the environment including image data of the object in the environment, and a label identifying the object. The present technology can further locate a position of the object in the 3-D simulation of the environment based on determining a depth and an orientation of the object in the environment based on a semantic database of attributes associated with the object, obtain a 3-D representation of the object from the semantic database of attributes associated with the object, and project the 3-D representation of the object into the 3-D simulation of the environment at the determined position for the object.Type: GrantFiled: November 16, 2021Date of Patent: February 20, 2024Assignee: GM Cruise Holdings LLCInventor: Ignacio Martin-Bragado

Publication number: 20230192120Abstract: The present technology pertains to increasing diversity of simulated autonomous vehicle (AV) environment scenes to be used for training machine learning (ML) models. Such an increase in diversity may be achieved by selecting objects from simulated AV environemnt scenes, and determining whether to add attachments to attachment points of the objects based on probabilities associated with the attachment points. When an attachment is to be added to an attachment point, the particular attachment is selected from among a set of compatible attachments.Type: ApplicationFiled: December 21, 2021Publication date: June 22, 2023Inventors: Ignacio Martin-Bragado, Leftheris Kaleas, Eugene Wong

Publication number: 20230192076Abstract: Disclosed herein are systems and methods including a method for improving how real assets are presented in simulations of street scenes. The method includes generating a simulation of a physical scene, the simulation having a first object with a first label and a second object with a second label, determining, via a model that applies a reaction map and a reaction distance, whether the first object and the second object should be clustered together such that the first label and the second label are replaced with a third label and outputting, from the model and based on the reaction map and the reaction distance being applicable to the first object and the second object, the third label for the first object and the second object.Type: ApplicationFiled: December 22, 2021Publication date: June 22, 2023Inventor: Ignacio Martin-Bragado

Publication number: 20230196130Abstract: Disclosed herein are systems and methods including a method for determining how real assets are in simulations of street scenes. The method includes generating a simulation in a meaningful way, the simulation having an asset, processing the simulation via a machine learning model, the machine learning model being trained to identify which classifications of assets are present in the simulation and output a quantitative number as a proxy for how real the asset would appear to a human viewer, determining, via the machine learning model, that the asset is a classification identified by the machine learning model and outputting, from the machine learning model, the quantitative number as the proxy for how real the asset would appear to the human viewer.Type: ApplicationFiled: December 17, 2021Publication date: June 22, 2023Inventor: Ignacio Martin-Bragado

Publication number: 20230153384Abstract: A classification model can be trained by using an augmented scene. The augmented scene may be generated by placing augmentation objects into a simulated scene that is a virtual representation of a real-world scene. The augmentation objects are virtual objects representing a category for which a reference classification model has a poor performance. The reference classification model may be a simulated model trained by using a simulated scene or a real-world model trained by using a real-world scene. A training set, which includes simulated sensor data of the augmentation objects and labels of the augmentation objects, can be used to train the augmented model. The augmented model can be used by an AV to classify objects in the surrounding environment of the AV. The augmented model can have a better accuracy in classifying objects in the category than the reference classification model.Type: ApplicationFiled: November 9, 2021Publication date: May 18, 2023Applicant: GM Cruise Holdings LLCInventors: Richard Stenson, Ignacio Martin-Bragado, Yibo Zhang

Publication number: 20220318464Abstract: Methods and systems are provided for augmenting simulations with machine learning data. In some aspects, a process can include steps for detecting a lack of data relating to a scenario in a real world environment, generating a simulation of the real world environment based on the detecting of the lack of data relating to the scenario, adding at least one asset to the simulation to satisfy the lack of data relating to the scenario, generating output data based on the simulation with the at least one asset, and updating a machine learning model based on the output data relating to the simulation with the at least one asset.Type: ApplicationFiled: March 31, 2021Publication date: October 6, 2022Inventors: Minhao Xu, Ignacio Martin Bragado, Yibo Zhang

Patent number: 10776539Abstract: A method for simulating an epitaxial process in a body having a crystal lattice structure. Roughly described, an enlarged version of the crystal lattice structure is formed, having a lattice constant increased by a lattice enlargement factor N>1. The subject fabrication process is simulated by a Lattice Kinetic Monte Carlo algorithm in which various factors have been scaled in accordance with N. The simulation speed increases by a factor around N3, without significantly degrading the accuracy of the resulting simulated structure. The simulated epitaxial process can later be performed on a physical crystalline body.Type: GrantFiled: December 1, 2017Date of Patent: September 15, 2020Assignee: Synopsys, Inc.Inventor: Ignacio Martin-Bragado
