Abstract

An object is to provide a database construction system for machine-learning that can automatically simply create virtual image data and teacher data in large volumes. A database construction system for machine-learning includes: a three-dimensional shape data input unit configured to input three-dimensional shape information about a topographic feature or a building acquired at three-dimensional shape information measuring means; a three-dimensional simulator unit configured to automatically recognize and sort environment information from the three-dimensional shape information; and a teacher data output unit configured to output virtual sensor data and teacher data based on the environment information recognized at the three-dimensional simulator unit and a sensor parameter of a sensor.

Claims (10)

1. A database construction system for machine-learning comprising:

a three-dimensional shape data input unit configured to input three-dimensional shape information about a topographic feature or a building acquired at a three-dimensional shape information measuring means;

a three-dimensional simulator unit configured to input vehicle information and automatically recognize and sort environment information from the three-dimensional shape information; and

a teacher data output unit configured to output virtual sensor data and teacher data based on the environment information recognized at the three-dimensional simulator unit, the vehicle information and a sensor parameter of a sensor,

wherein the three-dimensional shape data input unit includes:

a topographic three-dimensional shape data input unit configured to input the three-dimensional shape information, and

an object three-dimensional shape data input unit configured to input three-dimensional shape data of a given object; and

wherein the three-dimensional simulator unit includes a three-dimensional virtual space generating unit configured to integrate information of the topographic three-dimensional shape data input unit with information of the three-dimensional shape data input unit to generate virtual space.

2. The database construction system for machine-learning according to claim 1 ,

wherein the three-dimensional simulator unit includes a scenario autocreation unit configured to randomly create object three-dimensional shape information and a relative position of the object three-dimensional shape information based on the three-dimensional shape information input to the topographic three-dimensional shape data input unit, the environment information extracted at a three-dimensional environment recognition unit, and the three-dimensional shape data of the given object input to the object three-dimensional shape data input unit.
