Vehicle backup safety mapping
Method and apparatus are disclosed for vehicle backup safety mapping. An example vehicle includes a display, a rear-view camera, and a processor. The processor generates a three-dimensional model of space behind the vehicle based on images from the rear-view camera The processor also generates an overlay based on the three-dimensional model. The overlay includes representation of objects not in the field of view of the rear-view camera. Additionally, the processor displays, on the display, the images from the rear-view camera and the overlay.
1. A vehicle comprising:
a display;
vehicle position sensors;
a rear-view camera; and
a processor to:
generate a three-dimensional model of space behind the vehicle based on images from the rear-view camera;
track a location of the vehicle and the field of view of the rear-view camera in relation to the three-dimensional model of the space behind the vehicle based on measurements from the vehicle position sensors;
generate an overlay based on the three-dimensional model, the overlay including representation of objects not in a present field of view of the rear-view camera; and
display, on the display, the images from the rear-view camera and the overlay.
2. The vehicle of claim 1 , including a range detection sensor, and wherein the processor is to generate the three-dimensional model of the space behind the vehicle based on the images from the rear-view camera and measurements from the range detection sensor.
3. The vehicle of claim 2 , including side-view mirror cameras, and wherein the processor is to generate the three-dimensional model of the space behind the vehicle based on the images from the rear-view camera, the measurements from the range detection sensor, and images from the side-view mirror cameras.
4. The vehicle of claim 1 , wherein the overlay includes a cross-section of the model indicating edges of objects within the model.
5. The vehicle of claim 1 , wherein the processor is to classify objects detected by the rear-view camera.
6. The vehicle of claim 5 , wherein the overlay includes:
boxes around the objects extending into a portion of the overlay with representations of the objects not in the field of view of the rear-view camera; and
labels associated with the boxes identifying the corresponding objects.
7. The vehicle of claim 1 , wherein the processor is to provide an alert via an infotainment system when one of the objects is identified as a hazard.
8. The vehicle of claim 1 , wherein the processor is to provide an alert via an infotainment system when the vehicle comes within a threshold distance to an edge of one of the objects according to the model.
9. The vehicle of claim 1 , wherein the overlay includes a first indicia demarcating surfaces that are not in the field of view of the rear-view camera, and a second indicia demarcating surfaces that are in motion.
10. A method to assist a reverse moving vehicle, the method comprising:
generating, with a processor, a three-dimensional model of space behind the vehicle based on images from a rear-view camera;
generating an overlay based on the three-dimensional model, the overlay including a cross-section of the model representing edges of surfaces within the model;
displaying, on a center console display, the images from the rear-view camera and the overlay; and
providing an alert via an infotainment system when (i) one of the surfaces in the model is identified as belonging to a hazard or (ii) when the vehicle comes within a threshold distance to one of the surfaces according to the model.
11. The method of claim 10 , wherein generating the three-dimensional model of the space is also based on measurements from range detection sensors; and wherein the three-dimensional model of the space also includes areas to the side of the vehicle observable from the range detection sensors.
12. The method of claim 11 , wherein generating the three-dimensional model of the space is also based on the images from side-view mirror cameras, and wherein the three-dimensional model of the space also includes the areas to the side of the vehicle observable from the side-view mirror cameras.
13. The method of claim 10 , including tracking a location of the vehicle and a field of view of the rear-view camera in relation to the three-dimensional model of the space behind the vehicle based on measurements from vehicle position sensors.
14. The method of claim 10 , wherein the overlay includes a first indicia demarcating the surfaces that are not in a field of view of the rear-view camera, and a second indicia demarcating the surfaces that are in motion.
