Abstract
A method and device is provided for detecting a state change in an environment around a vehicle, and providing a notification in response to detecting a state change, wherein the detection involves determining a portion of the environment to capture, capturing a portion of the environment, detecting a state change in the captured portion, and the production of a notification in response to the change in the captured environment. Certain embodiments include traffic signal detection, vehicle detection, vehicle speed detection, and user adjustment of the detection.
Claims12
A drive assist device for a vehicle comprising:
- a camera configured to capture an environment around the vehicle;
- a display configured to display the sensed environment;
- a target setter configured to determine whether a user has designated a target region of the captured environment on the display, and when the target region is designated by the user, recognize the target region that is capable of a state change, as a corresponding target object;
- a detector configured to detect whether a state change has occurred of the recognized corresponding target object based on a change of image information;
- and
- a notification controller configured to control a notification to the user when the state change of the recognized corresponding target object is detected;
- and
- a conversion unit that converts a position on a first image suitable for visually checking the recognized corresponding target object imaged by the camera to a position corresponding to a position on a second image suitable for detecting the state change of the recognized corresponding target object imaged by another camera installed on the vehicle,
- wherein the display displays the first image,
- wherein the target setter sets the target region by the user on the first image as a recognized corresponding target object on the second image, and
- wherein, in response to the recognized corresponding target object being set, the detector detects the state change of the recognized corresponding target object on the second image.
A method of providing a state notification for a vehicle, wherein:
- the vehicle includes a camera configured to capture an environment around the vehicle, a display configured to display the sensed environment, and an electronic control unit including a processor programmed to execute drive assist notifications to a user, the method comprising:
- determining whether a user has designated a target region of the captured environment on the display, and when the target object is designated by the user, recognize the target region that is capable of a state change, as a corresponding target object;
- detecting whether a state change has occurred of the recognized corresponding target object based on a change of image information;
- notifying the user when the state change of the recognized corresponding target object is detected;
- and
- converting a position on a first image suitable for visually checking the recognized corresponding target object imaged by the camera to a position corresponding to a position on a second image suitable for detecting the state change of the recognized corresponding target object imaged by another camera installed on the vehicle,
- displaying the first image,
- setting the target region by the user on the first image as a recognized corresponding target object on the second image, and
- in response to the recognized corresponding target object being set, detecting the state change of the recognized corresponding target object on the second image.
