Description

FIELD OF THE INVENTION

The present invention relates generally to a vehicle vision system for a vehicle and, more particularly, to a vehicle vision system that utilizes one or more cameras at a vehicle.

BACKGROUND OF THE INVENTION

Use of imaging sensors in vehicle imaging systems is common and known. Examples of such known systems are described in U.S. Pat. Nos. 5,949,331; 5,670,935 and/or 5,550,677, which are hereby incorporated herein by reference in their entireties.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

A vehicle vision system and/or driver assist system and/or object detection system and/or alert system operates to capture images exterior of the vehicle and may process the captured image data to display images and to detect objects at or near the vehicle and in the predicted path of the vehicle, such as to assist a driver of the vehicle in maneuvering the vehicle in a rearward direction. The vision system includes an image processor or image processing system that is operable to receive image data from one or more cameras and provide an output to a display device for displaying images representative of the captured image data. Optionally, the vision system may provide display, such as a rearview display or a top down or bird's eye or surround view display or the like.

The camera or cameras (and processing of image data captured by the camera or cameras) can thus provide both drivers and automated driving systems (such as autonomous or semi-autonomous driving systems) information to enhance vehicle safety and maneuverability. However, cameras disposed at a vehicle are limited by the physics and the physical location where the camera is mounted at the vehicle.

For example, and such as shown in FIG. 1, a system may include a forward viewing camera 10, such as a camera mounted at and behind a windshield 12 of a vehicle 14, with the camera viewing forwardly through the windshield (such as through an area of the windshield swept or kept clean by the windshield wipers of the vehicle) and in the direction of forward travel of the vehicle. With the camera located at an upper region of the windshield, the camera cannot view directly in front of the vehicle due to the hood of the vehicle (see FIG. 2). Also, such a camera may have its view obstructed by other vehicles or trucks in front of the equipped vehicle (see FIG. 3).

The present invention incorporates an aerial platform or drone 16 at or in a vehicle 10 (as shown in FIGS. 1 and 4). The aerial platform or drone includes a platform or body that has a plurality of rotors or propellers or blades that are operable to elevate and maneuver or fly the aerial platform or drone via remote control or autonomous control or the like. The aerial platform or drone includes one or more cameras 16a for transmission of captured images for viewing by an operator of the drone. By incorporating such a drone in or at a vehicle, numerous advantages can be achieved. The drone, when deployed to fly over the vehicle (or around or near the vehicle), captures image data via its camera, whereby the captured image data may be communicated to the vision system of the vehicle, such as for image processing for object detection or the like, or for display of images for viewing by the driver of the vehicle. The drone may be vehicle specific and may follow the individual vehicle for which it is designated. Optionally, for larger vehicles, such as a bus or a truck, two or more drones may be designated for or incorporated at that vehicle.

Optionally, the drone may be tethered to the vehicle (such as via tether or cable or line 18 in FIG. 4) to provide a secure mount and power and communication (such as via an electrically conductive communication link), or the drone may be battery operated and may communicate with the vehicle vision system via a wireless communication link or the like. The drone may be deployed and used as needed, such as in traffic or for specific maneuvering of the vehicle.

The drone may be operable in a manner to avoid objects in its path of travel. Such objects may be avoided by keeping the drone height (as it is flying) above the ground to at or below levels based on standard commercial vehicle maximums (to avoid bridges, overpasses or the like). The drone may also be responsive to a GPS system of the vehicle (or the drone), where GPS identification of low clearance areas and the like may be used to adjust the drone's path of travel to avoid objects or the like.

Optionally, in some situations, the drone may achieve greater elevation in order to enhance visibility. For example, when the vehicle is stopped in heavy traffic (or is travelling very slowly in traffic), the drone's elevation may increase to allow the driver to view the area ahead of the vehicle to decide or select an alternative course of action or path of travel of the vehicle.

The image data captured by the drone camera is communicated to the control disposed at the vehicle, where the image data may be processed for object detection and/or may be used for display of images derived therefrom. For example, an image processor at the vehicle may process the image data captured by the drone camera to detect objects or other vehicles or the like in the field of view of the drone camera. Responsive to the image processing, the control may determine a high traffic condition or accident ahead of the equipped vehicle (but not yet in the driver's view or the vehicle camera's field of view), and the control may generate a communication or alert to the driver (such as an audible alert or a visual display or the like) that is indicative of or representative of the detected or determined traffic condition ahead of the vehicle. Optionally, the communication may comprise display of images derived from the image data captured by the drone camera.

Therefore, the present invention provides a vision system that uses a drone or aerial platform and camera to provide enhanced viewing and image data capture of areas ahead or around the vehicle that may not be viewable by a camera or cameras of the vehicle (such as due to traffic or objects obstructing the field of view of the vehicle-based camera or cameras). The drone may be detached from and launched from the vehicle (such as from a docking station at the vehicle, such as at an exterior portion of the vehicle, with the docking station optionally providing for charging of the drone's battery when the drone is docked or attached at the vehicle) and may fly above or at or near the vehicle to capture image data of the area ahead of or surrounding the vehicle.

Optionally, control of the drone may be responsive to communication with the system of the vehicle, such that the drone travels with the vehicle and maintains a position generally above the vehicle as the vehicle is driven along the road. A vehicle-based control may control the drone (via wired or wireless communication) to follow the vehicle or to stray from the vehicle to view other areas remote of the vehicle. For example, if a traffic jam or high traffic situation occurs ahead of the vehicle, the control may control the drone to fly ahead to see the cause and/or length of the traffic backup. Optionally, the control may control the drone responsive to a user input, such as a voice command from the driver or such as a joystick control or such as a touch screen or the like in the vehicle. For example, the driver (or a passenger) of the vehicle may provide an input so that the control controls the drone to fly to a different location, such as sideward or rearward or ahead of where the vehicle is at). For example, a map display may be provided at a touch screen of the vehicle, and a user may touch a location near the vehicle, whereby the control controls the drone to fly to that location and capture image data of that location.

Optionally, the camera of the drone may be adjusted to view forwardly of the vehicle in the direction of travel of the vehicle, or the drone may rotate to direct the camera in any suitable or desired direction, such as in a direction where a camera of the vehicle (such as a front, side or rear camera) has its field of view at least partially obstructed. For example, if a side viewing camera has its field of view at least partially obstructed (such as determined via image processing of image data captured by that camera), the drone may be deployed and may rotate to have its camera (or one of its cameras if equipped with more than one camera) view in the direction of the side viewing (obstructed) camera. Thus, the drone may be operable to function as a spare camera to provide enhanced viewing for any camera of the vehicle that may at that time be obstructed.

The drone may communicate (in real time) captured image data to the vision system of the vehicle (such as for display of captured video images or for processing of captured image data), or the drone may store captured image data for later display or processing when the drone returns to the vehicle and docks at the vehicle. Optionally, the drone may include an image processor that processes captured image data, whereby the drone may communicate a signal to the vehicle vision system that is indicative of a detected object or the like.

Thus, responsive to a user input or responsive to processing of image data captured by one or more cameras of the vehicle or responsive to a communication from another vehicle or from infrastructure or the like, the control may cause the drone to detach from the vehicle or docking base at the vehicle and to fly above the vehicle to capture image data of areas outside of the field(s) of view of the vehicle camera(s) (such as beyond obstructions in the field(s) of view of the vehicle camera(s) or ahead of the vehicle beyond the field of view of a forward viewing vehicle camera or the like). The drone, when docked at the vehicle, may be disposed at an exterior of the vehicle (and may be hooked or clamped or otherwise retained at the docking station) and/or may rest in a recess of the vehicle and/or may be docked in a closed compartment of the vehicle (with the compartment having a panel that slides or pivots to open to deploy the drone and closes when the drone is docked at the vehicle. The control, when deploying the drone, controls the drone rotors and the docking station (to release hooks or clamps and/or to open a panel or the like) so that the drone can detach from the vehicle and elevate and fly above the vehicle. The drone flies above the vehicle and captures image data representative of areas outside of the field(s) of view of the vehicle camera(s) to provide enhanced object detection at obstructed areas or distant areas and/or to provide display of video images of such obstructed areas or distant areas.

The vehicle-based vision system receives image data captured by vehicle-based cameras and by the drone, and includes an image processor operable to process the captured image data, such as for detecting objects or other vehicles or pedestrians or the like in the field of view of one or more of the cameras. For example, the image processor may comprise an image processing chip selected from the EYEQ family of image processing chips available from Mobileye Vision Technologies Ltd. of Jerusalem, Israel, and may include object detection software (such as the types described in U.S. Pat. Nos. 7,855,755; 7,720,580 and/or 7,038,577, which are hereby incorporated herein by reference in their entireties), and may analyze image data to detect vehicles and/or other objects. Responsive to such image processing, and when an object or other vehicle is detected, the system may generate an alert to the driver of the vehicle and/or may generate an overlay at the displayed image to highlight or enhance display of the detected object or vehicle, in order to enhance the driver's awareness of the detected object or vehicle or hazardous condition during a driving maneuver of the equipped vehicle.

The imaging sensor or camera may capture image data for image processing and may comprise any suitable camera or sensing device, such as, for example, a two dimensional array of a plurality of photosensor elements arranged in at least 640 columns and 480 rows (at least a 640×480 imaging array, such as a megapixel imaging array or the like), with a respective lens focusing images onto respective portions of the array. The photosensor array may comprise a plurality of photosensor elements arranged in a photosensor array having rows and columns. Preferably, the imaging array has at least 300,000 photosensor elements or pixels, more preferably at least 500,000 photosensor elements or pixels and more preferably at least 1 million photosensor elements or pixels. The imaging array may capture color image data, such as via spectral filtering at the array, such as via an RGB (red, green and blue) filter or via a red/red complement filter or such as via an RCC (red, clear, clear) filter or the like. The logic and control circuit of the imaging sensor may function in any known manner, and the image processing and algorithmic processing may comprise any suitable means for processing the images and/or image data.

For example, the vision system and/or processing and/or camera and/or circuitry may utilize aspects described in U.S. Pat. Nos. 9,233,641; 9,146,898; 9,174,574; 9,090,234; 9,077,098; 8,818,042; 8,886,401; 9,077,962; 9,068,390; 9,140,789; 9,092,986; 9,205,776; 8,917,169; 8,694,224; 7,005,974; 5,760,962; 5,877,897; 5,796,094; 5,949,331; 6,222,447; 6,302,545; 6,396,397; 6,498,620; 6,523,964; 6,611,202; 6,201,642; 6,690,268; 6,717,610; 6,757,109; 6,802,617; 6,806,452; 6,822,563; 6,891,563; 6,946,978; 7,859,565; 5,550,677; 5,670,935; 6,636,258; 7,145,519; 7,161,616; 7,230,640; 7,248,283; 7,295,229; 7,301,466; 7,592,928; 7,881,496; 7,720,580; 7,038,577; 6,882,287; 5,929,786 and/or 5,786,772, and/or U.S. Publication Nos.
