Abstract
An apparatus and method for lane feature detection from an image is performed according to predetermined path geometry. An image including at least one path is received. The image may be an aerial image. Map data, corresponding to the at least one path and defining the predetermined path geometry is selected. The image is modified according to the selected map data including the predetermined path geometry. A lane feature prediction model is generated or configured based on the modified image. A subsequent image is provided to the lane feature prediction model for a prediction of at least one lane feature.
Claims20
A method for lane feature detection from an image, the method comprising:
- receiving an image including at least one road;
- generating a ground truth mask including at least one road geometry for the at least one road;
- modifying the image according to ground truth mask;
- generating, using a processor, a lane feature prediction model based on the modified image;
- and
- providing a subsequent image to the lane feature prediction model for a prediction of at least one lane feature.
An apparatus for lane feature detection from an image according to predetermined path geometry, the apparatus comprising:
- a controller configured to identify map data corresponding to at least one road having a geometry and generate a ground truth mask including for the at least one road;
- an aerial image editor configured to modify the image according to the ground truth mask and the geometry of the at least one road;
- and
- a lane feature model trained according to the modified image and configured to identify at least one lane feature from a subsequent image.
A non-transitory computer readable medium including instructions that when executed by a process are configured to perform:
- receiving an image including at least one road;
- generating a ground truth mask including at least one road geometry for the at least one road;
- modifying the image according to ground truth mask;
- generating, using a processor, a lane feature prediction model based on the modified image;
- and
