Systems and methods for locating objects

1. A method, comprising:

determining a point of interest (POI) in an image generated by a camera associated with a vehicle, wherein the POI is associated with a physical object;

determining a first distance from the POI to the camera using pixels from the image and an angle of the camera;

determining a second distance from the camera to a Global Positioning System (GPS) unit associated with the vehicle; and

adding the first distance to the second distance to determine an offset distance from the POI to the GPS unit associated with the vehicle.

2. The method of claim 1 , further comprising; receiving a GPS location generated by the GPS unit associated with the vehicle, wherein the GPS location is represented by latitude and longitude coordinates; determining a travel direction of the vehicle along a railroad track, wherein the vehicle is a track geometry car; and determining a POI location associated with the physical object using the GPS location, the offset distance, and the travel direction of the vehicle, wherein the POI location is represented by latitude and longitude coordinates.

3. The method of claim 1 , wherein; the camera is mounted to a front top end of the vehicle; and the GPS unit is mounted to a center top portion of the vehicle.

4. The method of claim 1 , further comprising; detecting an object in the image; determining an object POI in the detected object of the image; and mapping the object POI to a center of a railroad track in the image to generate the POI.

5. The method of claim 1 , further comprising; comparing the POI location associated with the physical object to a field measurement location associated with the physical object; determining that the P 01 location and the field measurement location are separated by more than a predetermined distance; and applying a defect to the physical object in response to determining that the POI location and the field measurement location are separated by more than a predetermined distance.

6. The method of claim 1 , wherein determining a first distance from the POI to the camera using pixels from the image comprises converting each of the pixels to a distance, each of the pixels being associated with a different distance.

7. The method of claim 1 , wherein the physical object represents at least one of the following positive train control (PTC) critical assets; a train-controlled signal; a switch point; a crossing; a mile post sign; a speed sign; and a clearance point.

8. A system comprising one or more processors and a memory storing instructions that, when executed by the one or more processors, cause the one or more processors to perform operations comprising:

determining a point of interest (POI) in an image generated by a camera associated with a vehicle, wherein the POI is associated with a physical object;

determining a first distance from the POI to the camera using pixels from the image and an angle of the camera;

determining a second distance from the camera to a Global Positioning System (GPS) unit associated with the vehicle; and

adding the first distance to the second distance to determine an offset distance from the POI to the GPS unit associated with the vehicle.

9. The system of claim 8 , the operations further comprising; receiving a GPS location generated by the GPS unit associated with the vehicle, wherein the GPS location is represented by latitude and longitude coordinates; determining a travel direction of the vehicle along a railroad track, wherein the vehicle is a track geometry car; and determining a POI location associated with the physical object using the GPS location, the offset distance, and the travel direction of the vehicle, wherein the POI location is represented by latitude and longitude coordinates.

10. The system of claim 8 , wherein; the camera is mounted to a front top end of the vehicle; and the GPS unit is mounted to a center top portion of the vehicle.

11. The system of claim 8 , the operations further comprising; detecting an object in the image; determining an object POI in the detected object of the image; and mapping the object POI to a center of a railroad track in the image to generate the POI.

12. The system of claim 8 , the operations further comprising; comparing the POI location associated with the physical object to a field measurement location associated with the physical object; determining that the POI location and the field measurement location are separated by more than a predetermined distance; and applying a defect to the physical object in response to determining that the POI location and the field measurement location are separated by more than a predetermined distance.

13. The system of claim 8 , wherein determining a first distance from the POI to the camera using pixels from the image comprises converting each of the pixels to a distance, each of the pixels being associated with a different distance.

14. The system of claim 8 , wherein the physical object represents at least one of the following positive train control (PTC) critical assets; a train-controlled signal; a switch point; a crossing; a mile post sign; a speed sign; and a clearance point.

15. One or more non-transitory computer-readable storage media embodying instructions that, when executed by a processor, cause the processor to perform operations comprising:

determining a point of interest (POI) in an image generated by a camera associated with a vehicle, wherein the POI is associated with a physical object;

determining a first distance from the POI to the camera using pixels from the image and an angle of the camera;

determining a second distance from the camera to a Global Positioning System (GPS) unit associated with the vehicle; and

adding the first distance to the second distance to determine an offset distance from the POI to the GPS unit associated with the vehicle.

16. The one or more non-transitory computer-readable storage media of claim 15 , the operations further comprising; receiving a GPS location generated by the GPS unit associated with the vehicle, wherein the GPS location is represented by latitude and longitude coordinates; determining a travel direction of the vehicle along a railroad track, wherein the vehicle is a track geometry car; and determining a POI location associated with the physical object using the GPS location, the offset distance, and the travel direction of the vehicle, wherein the POI location is represented by latitude and longitude coordinates.

17. The one or more non-transitory computer-readable storage media of claim 15 , wherein; the camera is mounted to a front top end of the vehicle; and the GPS unit is mounted to a center top portion of the vehicle.

18. The one or more non-transitory computer-readable storage media of claim 15 , the operations further comprising: detecting an object in the image; determining an object POI in the detected object of the image; and mapping the object POI to a center of a railroad track in the image to generate the POI.

19. The one or more non-transitory computer-readable storage media of claim 15 , the operations further comprising: comparing the POI location associated with the physical object to a field measurement location associated with the physical object; determining that the POI location and the field measurement location are separated by more than a predetermined distance; and applying a defect to the physical object in response to determining that the POI location and the field measurement location are separated by more than a predetermined distance.

20. The one or more non-transitory computer-readable storage media of claim 15 , wherein determining a first distance from the POI to the camera using pixels from the image comprises converting each of the pixels to a distance, each of the pixels being associated with a different distance.
