Systems and methods for detecting an open door

A computer-implemented method for navigating a host vehicle, the computer-implemented method comprising:

• receiving an image frame acquired by an image capture device associated with the host vehicle, wherein the image frame is representative of an environment of the host vehicle;
• identifying in the image frame a representation of a target vehicle;
• determining one or more orientation indicators associated with the target vehicle;
• based on the determined one or more orientation indicators, identifying at least one candidate region of the acquired image frame where a representation of a vehicle door of the target vehicle is expected in an open door condition;
• extracting the at least one candidate region from the image frame;
• providing the extracted at least one candidate region to an open door detection network;
• determining at least one navigational action for the host vehicle in response to an indication from the open door detection network that the extracted at least one candidate region includes a representation of a door of the target vehicle in an open condition;
• and
• causing one or more actuators associated with the host vehicle to implement the at least one navigational action.

A non-transitory computer-readable medium storing instructions that, when executed by at least one processor, cause the at least one processor to perform operations comprising:

• receiving an image frame acquired by an image capture device associated with a host vehicle, wherein the image frame is representative of an environment of the host vehicle;
• identifying in the image frame a representation of a target vehicle;
• determining one or more orientation indicators associated with the target vehicle;
• based on the determined one or more orientation indicators, identifying at least one candidate region of the acquired image frame where a representation of a vehicle door of the target vehicle is expected in an open door condition;
• extracting the at least one candidate region from the image frame;
• providing the extracted at least one candidate region to an open door detection network;
• determining at least one navigational action for the host vehicle in response to an indication from the open door detection network that the extracted at least one candidate region includes a representation of a door of the target vehicle in an open condition;
• and
• causing one or more actuators associated with the host vehicle to implement the at least one navigational action.
