Similar to first portable imager 12, as shown in
Similar to what is done with images captured by first portable imager 12, image processor 30 may likewise be capable of receiving second images from the second portable imager 12A and processing the second images to create at least one additional image from the second images. In some embodiments, image processor 30 may be configured to crop the second images received from the second portable imager 12A into a group of additional images. The group of additional images may include a first additional image that comprises a lower portion of the second field of view such as, for example, an image encompassing a trailer hitch. The group of additional images may further include a second additional image having a higher portion of the second field of view such as a field of view forward of and/or above the vehicle 25. For example, the higher portion of the second field of view may be of the bed of a truck that is pulling trailer 15. In some embodiments, for example, the at least one additional image from each second image captured by the second portable imager 12A may comprise first additional image of a scene immediately adjacent to the trailer 15 and second additional image comprising a scene on the same side of the trailer 15 as the first additional image but showing it from a field of view that captures objects further away from the trailer 15 than those in the first additional image. In another example, the at least one additional image from each second image captured by the first portable imager 12 may comprise a first additional image of a scene immediately behind the towing vehicle 25 and including the trailer hitch. The at least one additional image may further comprise a second additional image comprising a scene of the front of the trailer 15. In yet another example, the at least one additional image from each second image captured by the first portable imager 12 may comprise a first additional image of a scene inside the trailer 15. The first additional image may show the floor and/or a lower portion of the interior of the trailer 15. The at least one additional image may further comprise a second additional image comprising a scene of the interior of the trailer 15 but of a higher portion of the interior of the trailer 15 than that in the first additional image. In some embodiments, second portable imager 12A may capture a second image and process only a portion of the image for display, for example a single field of view of an interior of the trailer 15.
Portable imagers 12, 12A may be in communication with a memory 31. Portable imagers 12, 12A may be configured to transmit image data from captured images to memory 31. Memory 31 may be configured to store the transmitted image data for a period of time. In some embodiments, memory 31 may store image data, for example, for a certain time period, after which new image data may be stored in its place (due to limitations of storage capacity). In some embodiments, memory 31 may record only upon certain criteria being met such as the receipt of an input from a sensor such as a motion detector. The input may indicate, for example, that motion has been detected within a trailer 15 or in the proximity of a trailer 15 or trailer hitch (not shown). In some embodiments, memory 31 may record upon the receipt of a particular input from a user interface (not shown) or other criteria such as the vehicle 25 being put into motion or being parked. Upon receipt of the input, at least one portable imager 12, 12A of image and display system 10 may begin to capture images and memory 31 may store image data from the captured images. The capture and storage of image data may continue until the occurrence of an event that causes the memory 31 to stop storing image data. The event may be, for example, the passage of a predetermined amount of time, the passage of a predetermined time during which no further inputs are received, the receipt of a user input, and the like.

Turning to
PCB 46 may also include a wireless communication chip or module 48 thereon with a connector 50 extending therefrom to couple with antenna 36. This may allow portable imager 12, 12A to be configured for wireless communication with image and display system 10, including by one or more wireless communication protocols suitable for streaming video.
As discussed above, lens barrel 32 may retain lens 28 therein to form lens unit 26. In some embodiments, lens barrel 32 may retain additional lenses (not shown) configured to assist lens 28 to focus first field of view A onto image sensor 14. Lens barrel 32 may extend through and be externally exposed within the aperture 24 in first cover 21. Lens barrel 32 may be sealed therein by a deposited material or separate sealing member. A lens holder 33 having an aperture 35 may couple PCB 46 with lens unit 26. Lens holder 33 may be configured to position lens unit 26 and lens 28 to be aligned with image sensor 14 by affixing lens barrel 32 within aperture 35 of lens holder 33.
Lens barrel 32 may be affixed within aperture 35 using various adhesives, cements, or the like or may be press-fit within aperture 35. Lens holder 33 may be secured to PCB 46, and may be disposed adjacent to or surrounding image sensor 14. The securing of lens holder 33 to PCB 46 may be done by using adhesives, or one of lens holder 33 and PCB 46 may be adapted to be affixed using screws or other mechanical fasteners. In one aspect, the lens barrel 32 may be aligned with lens holder 33 for proper alignment of lens 28 with image sensor 14 and retained in position during curing of a cement or other adhesive requiring curing such that lens unit 26 may be affixed to PCB 46 and configured for proper alignment with image sensor 14 when portable imager 12 is assembled, as discussed further below.
Continuing with respect to
As further shown in
The resulting assembly may be secured with respect to center band 18 by the abutting of second cover 22 with a plurality of flanges 72 adjacent the open second side of center band 18 such that second cover 22 may be recessed into center band 18 in a manner similar to first cover 21. As with first cover 21, a sealing gasket or other member(s) may be positioned between flanges 72 and the adjacent portions of the interior surface of second cover 22. The addition of such an element may provide sealing of housing 16 and may allow fora compression fit of first and second covers 21, 22 with center band 18 with PCB 42 being received between projections 64 and supports 60 under a desired level of compression. After assembly of second cover 22, the antenna 36 may be assembled with connector 50 through an aperture 37 in one of center band 18, first cover 21, and second cover 22.
As shown in
Control board 54 may also couple with an internal power source (e.g. a rechargeable or replaceable battery, not shown) that may be received within housing 16 to power the operation of portable imager 12, including the operation of image sensor 14 and wireless module 48.
Control board 54 may be secured to supports 60 by additional screws 70 passing through holes 66 in control board 54 and engaging with inserts 68 received within hollow portions of supports 60. Supports 60 and buttons may be mutually sized and positioned such that buttons 38, 42, 44 may engage with corresponding switches on control board 54 for operation thereof. In some embodiments, reset button 44 may be formed on a separate body that may be received with button module 58 for operation of a corresponding switch on control board 54.
The assembled button module 58 and control board 54 may be assembled with housing by additional screws 70 that pass through holes 66 in button module 58 and engage with threaded holes 74 in center band 18 and are positioned such that buttons 38, 42, and 44 are aligned with corresponding apertures 76 in central band. In this manner, a separate membrane (not shown) may define an operable surface for buttons 38, 42, and 44 and may seal against the interior of center band 18 to further seal housing 16.
In assembly of portable imager 12, 12A, the control board 54 may be assembled with button module 58, which may then be assembled with center band 18 prior to the assembly of PCB 46 and first and second covers 21 and 22 with center band 18. Additionally, a battery may be connected with control board 54 and positioned within housing 16 before assembly of second cover 22 with center band 18 and securement of the assembly with the screws 70 that engage between second cover 22 and first cover 21. In an alternative arrangement, the functionality of control board 54 and PCB 46 may be incorporated into a single PCB with the switches arranged parallel to the PCB for actuation by the illustrated buttons in a variation of the illustrated button module lacking the supports of the illustrated embodiment and assembled separately with center band 18 from the single PCB.
With reference to
Using first portable imager 12 as an example, the image processor 30 may be configured to create the back-up image 52 so that it corresponds to a portion B of the first field of view A cropped from a lower portion of the first field of view A. The portion B of the first field of view A may have the same horizontal angle H as the first field of view A. Thus, when looking at the image sensor 14 of the first portable imager 12 as shown in
The rearward image 55 may be read from a subset of pixels in the top half of the image sensor across all or nearly all the columns of pixels. For example, the rearward image 55 may be read from about 30 rows in the top half of the image sensor across all or nearly all the columns of pixels. Depending upon lenses used in the first portable imager 12, this may represent a third portion C of first field of view A having a horizontal angle and a third vertical angle. For example, the portion C of first field of view A may have a horizontal angle of 70 degrees and a vertical angle of 15 degrees, which may represent an aspect ratio of at least about 4:1. Thus, the rearward image 55 corresponding to portion C of first field of view A may be cropped from a portion of the first field of view A above the lower portion, and the third portion C of first field of view A may have a horizontal angle and a vertical angle where the horizontal angle may be greater than the vertical angle.
The portable imagers 12, 12A may be in communication with the image processor 30 by wired or wireless connection 13 and 13A, respectively. The image processor 30 may select images from the second portable imager 12A when the vehicle 25 is not coupled to the trailer 15 and the vehicle 25 is backing up while within range for wireless communication with the second portable imager 12A. This may better allow a driver to back the vehicle 25 up to attach the trailer 15 to the trailer hitch or to determine how far the vehicle 25 can be backed up without hitting the trailer 15. When the vehicle 25 and the trailer 15 are coupled, the image processor 30 may select images from the first portable imager 12. When the vehicle 25 is not coupled to the trailer 15 and not within range for wireless communication with the portable imagers 12, 12A, image processor 30 may process images from vehicle imager(s) 20 for display on the display 40.
Display 40 may be in communication with image processor 30 and may be capable of selectively displaying at least one of the first image, second image, first supplementary image, second supplementary image, first additional image, and second additional image. Display 40 may also be capable of displaying images from vehicle imagers 20. Display 40 may be configurable to display images from at least one of first portable imager 12, second portable imager 12A, and both first and second portable imagers 12, 12A.
The display 40 may be configured for mounting within a rearview assembly mounted to one of a roof and a windshield of the vehicle 25. Thus, the display 40 may serve as a replacement or supplement to an internal rearview mirror. Additionally, or alternatively, the display 40 may be provided elsewhere in the vehicle 25 such as in a center stack of an instrument panel.
The image processor 30 may be configured to receive an input indicating whether the vehicle 25 is in a reverse gear. When the vehicle 25 is not in reverse, the image processor 30 may only read the rearward image 55 from the image sensor 14 of the first portable imager 12 and format the rearward image for display across the entire display 40 as shown in
It may also be possible to configure the image processor 30 to receive an input from a user input that allows a driver to select which images to display on display 40. Although a reverse gear input may be described as one input to the image processor 30, various other signals could be used to trigger a change in what is displayed on display 40. For example, inputs may be received from an ultrasonic backup signal, a user button, or a vehicle speed. For example, when the vehicle 25 is traveling at a low speed, the back-up image 52 and the rearward image 55 may be simultaneously displayed.
Although the above description pertains to portable imagers 12, 12A, one or more vehicle cameras or imagers 20 may be mounted such that they capture first images from a field of view having a horizontal angle and a vertical angle where the vertical angle may be greater than the horizontal angle and where the field of view has an aspect ratio of about 9:16. The image processor 30 may likewise crop the first images received from the vehicle imager 20 into a first supplementary image and a second supplementary image. The first supplementary image may comprise a back-up image. The back-up image may be of a lower field of view encompassing either a hitch mounted to the vehicle 25 or a bed of the vehicle 25. The second supplementary image may be of a higher field of view such as rearward of the vehicle 25, for example. Based on an input received by the image processor 30, the image processor 30 may select either one or both of the first supplementary and the second supplementary images for display on the display 40. The input may be, for example, related to a vehicle gear, vehicle speed, user input, ultrasonic back-up signal, and the like.
Image and display system 10 may also provide additional trailer views such as a view of the tow vehicle 25 from behind, an interior trailer view and a surround view. Image and display system 10 may be configured to record the images from portable imager(s) 12, 12A if sensors in communication with image and display system 10 indicate there is movement in the trailer or movement in proximity to the exterior of the trailer when the vehicle 25 is stopped or parked. Image and display system may be configured to cause a notification to be transmitted to a user. The notification may be transmitted via WIFI or LTE. The user may then be able to view or download captured images and/or video.
Portable imager 12 and/or 12A (or an additional imager) may be provided inside and/or outside of trailer 15 to capture images inside the trailer or outside the trailer. If provided inside the trailer, cargo (e.g., livestock) may be monitored. Further, the trailer imager(s) may be used as security imager(s) for monitoring the area around and inside the trailer 15.
The user interface may be capable of, upon receipt of a user input, saving images captured within a predetermined time interval prior to the receipt of the user input. In some embodiments, video images captured by portable imager(s) 12, 12A may be streamed and/or recorded for real-time or subsequent viewing on display 40 or on a user's mobile phone or other device. In some embodiments, video captured by portable imager(s) 12, 12A may be stored in memory 31 for a period of time.
In some embodiments, image and display system 10 may be configured to automatically, upon receipt of a particular user input, save images captured for a predetermined amount of time prior to the receipt of the input. Image and display system may further be configured to save images for a period after the receipt of the particular user input.
The rearview mirror assembly further may comprise a user interface capable of, upon receipt of a user input, causing the saving of images captured within a predetermined time interval prior to the receipt of the user input.
Image and display system 10 may be configured to store image data from captured images in memory 31. Memory 31 may be local to image and display system 10. In some embodiments, image and display system 10 may be in communication with and configured to store image data in a media storage card. Alternatively, or additionally, image and display system 10 may store image data from captured images in a remote memory 39, such as a remote server or cloud storage. User may be capable of accessing images stored in memory 31, 39 and causing images to be displayed on display 40. In some embodiments, image and display system 10 may be capable of causing images from image data stored in memory 31, 39 to be displayed on a mobile communications device such as a smart phone or a tablet computer.
Memory 31, 39 may comprise a certain storage capacity for storing images. Once the storage capacity has been reached, new images may be written over previously-stored images, thereby erasing the previously-stored images. Image and display system may be configured to write over the oldest stored images first.
In some embodiments, a user may indicate through user interface that the user desires images be saved. For example, image and display system 10 may receive, through user interface, an input indicating that images should be saved. Upon receipt of the indication, image processor 30 may place images captured within a predetermined period of time, such as the ninety seconds prior to the receipt of the input, into a saved status.
Images may be placed in a saved status and may remain in the saved status until the receipt of a user input indicating that the particular saved images no longer need to be in a saved status and may be over-written with new images. If images are in a saved status, those images may not be written over until the occurrence of a predetermined event. This may be done by a user via a user interface or other means, after the images in the saved status have been viewed, by the passage of a predetermined amount of time, or according to another criteria. The predetermined event may be the passage of a set period of time, the receipt of a particular user input, and the like.
Image and display system 10 may be configured to be activated upon the vehicle 25 being turned on or the ignition of the vehicle 25 being started. In some embodiments, once image and display system 10 has been activated, first portable imager 12 may begin capturing images. In some embodiments, first portable imager 12 may begin capturing images once a particular event has occurred. The particular event may be, for example, putting the vehicle 25 into a forward or reverse gear or interacting with a user interface (not shown) of image and display system 10. Second portable imager 12A may be activated simultaneously with first portable imager 12 or separately.
Power may be supplied to image and display system 10 by a power supply (not shown). Power supply may be associated with the vehicle 25 or may be associated with image and display system 10. In some embodiments, image and display system 10 may be configured to turn off after the vehicle ignition and/or power to the vehicle accessories is turned off. In some embodiments, image and display system 10 may continue to operate until the occurrence of a particular event or for a predetermined period of time after the vehicle ignition and/or power to vehicle accessories is turned off.
