Abstract

A control device used to generate a control command to cause a mobile object to move by driverless driving includes a matching section configured to perform matching using measured point cloud data and reference point cloud data in order to generate the control command, and a mobile object information acquisition section configured to acquire mobile object information by which an appearance feature of the mobile object is identified. The matching section is configured to perform the matching according to the mobile object information. The measured point cloud data is three-dimensional point cloud data on the mobile object acquired by using a distance measurement device. The reference point cloud data is date representing three-dimensional point cloud data for reference.

Claims (29)

1 . A control device used to generate a control command to cause a mobile object to move by driverless driving, comprising:

a matching section configured to perform matching using measured point cloud data and reference point cloud data in order to generate the control command;

a mobile object information acquisition section configured to acquire mobile object information by which an appearance feature of the mobile object is identified, wherein

the matching section is configured to perform the matching according to the mobile object information,

the measured point cloud data is three-dimensional point cloud data of the mobile object acquired by using a distance measurement device, and

the reference point cloud data is data representing three-dimensional point cloud data for reference; and

a command generation section configured to generate the control command including a travel control signal to control actuators of the mobile object to perform moving of the mobile object by driverless driving to a target position based on the matching,

wherein the travel control signal is sent to the actuators of the mobile object.

2 . The control device according to claim 1 , wherein:

the mobile object information includes model code information by which a model code of the mobile object is identified;

the reference point cloud data includes model code point cloud data corresponding to the model code; and

the matching section is configured to perform the matching by using the model code point cloud data according to the model code information.

3 . The control device according to claim 2 , wherein the mobile object information includes, as the model code information, manufacture information used to manage process of manufacturing the mobile object.

4 . The control device according to claim 1 , wherein the matching section is configured to change at least one of density of a point cloud in the measured point cloud data and density of a point cloud in the reference point cloud data, according to the mobile object information.

5 . The control device according to claim 4 , wherein the matching section is configured to change at least one of the density of the point cloud in the measured point cloud data and the density of the point cloud in the reference point cloud data, according to a distance between the distance measurement device and the mobile object.

6 . A control device used to generate a control command to cause a mobile object to move by driverless driving, comprising a processor configured to execute:

performing matching using measured point cloud data and reference point cloud data in order to generate the control command;

acquiring mobile object information by which an appearance feature of the mobile object is identified;

performing the matching according to the mobile object information, wherein the measured point cloud data is three-dimensional point cloud data on the mobile object acquired by using a distance measurement device, and

the reference point cloud data is data representing three-dimensional point cloud data for reference; and

generating the control command including a travel control signal to control actuators of the mobile object to perform moving of the mobile object by driverless driving to a target position based on the matching,

wherein the travel control signal is sent to the actuators of the mobile object.

7 . The control device according to claim 6 , wherein:

the mobile object information includes model code information by which a model code of the mobile object is identified;

the reference point cloud data includes model code point cloud data corresponding to the model code; and

the processor is further configured to execute the matching by using the model code point cloud data according to the model code information.

8 . The control device according to claim 7 , wherein the mobile object information includes, as the model code information, manufacture information used to manage process of manufacturing the mobile object.

9 . The control device according to claim 6 , wherein the processor is further configured to execute changing at least one of density of a point cloud in the measured point cloud data and density of a point cloud in the reference point cloud data, according to the mobile object information.

10 . The control device according to claim 9 , wherein the processor is further configured to execute changing at least one of the density of the point cloud in the measured point cloud data and the density of the point cloud in the reference point cloud data, according to a distance between the distance measurement device and the mobile object.
