The present invention relates to multi-camera systems for use in vehicles, and more particularly multi-camera systems for use in vehicles wherein image manipulation is carried out on the images prior to displaying the images to a vehicle occupant.
There are few multi-camera systems currently available in vehicles. Such systems incorporate four cameras typically, and provide a vehicle occupant with a composite image that is generated from the images taken by the four cameras. However, such systems can require a relatively large amount of processing power to generate the image that is displayed to the vehicle occupant, particular in situations where there is manipulation of the images being carried out. Such manipulation of the images may include dewarping, among other things.
It would be beneficial to provide a multi-camera system for a vehicle that requires relatively little processing power.
In a first aspect, the invention is directed to a method of establishing a composite image for displaying in a vehicle, comprising:
a) providing a first camera and a second camera, each camera having a field of view;
b) positioning the cameras so that the fields of view of the cameras overlap partially, wherein the cameras together have a combined field of view;
c) recording preliminary digital images from the cameras, each preliminary digital image being made up of a plurality of pixels; and
d) generating a final composite digital image that corresponds to a selected digital representation of the combined field of view of the cameras by remapping selected pixels from each of the preliminary digital images into selected positions of the final composite digital image.
In a second aspect, the invention is directed to a method of establishing a composite image for displaying in a vehicle, comprising:
a) providing a first camera and a second camera, a third camera and a fourth camera, each camera having a field of view, wherein the cameras together have a combined field of view that is a 360 degree field of view around the vehicle;
b) positioning the cameras so that the field of view of each camera overlaps partially with the field of view of two of the other cameras;
c) recording preliminary digital images from the cameras, each preliminary digital image being made up of a plurality of pixels; and
d) generating a final composite digital image that corresponds to a selected digital representation of the combined field of view of the cameras by remapping selected pixels from each of the preliminary digital images into selected positions of the final composite digital image,
wherein the preliminary digital images each have associated therewith a preliminary apparent camera viewpoint and the final composite digital image has associated therewith a final apparent camera viewpoint,
and wherein the selected pixels from the preliminary digital images are selected so that the final apparent camera viewpoint associated with the final composite digital image is higher than the preliminary apparent camera viewpoints associated with the preliminary digital images,
and wherein the selected pixels from the preliminary digital images are selected so that any misalignment between the overlapping portions of the preliminary digital images is substantially eliminated,
and wherein the selected pixels from the preliminary digital images are selected so that the final composite digital image is dewarped as compared to each of the preliminary digital images.
In a third aspect, the invention is directed to a system for establishing a composite image for displaying in a vehicle, comprising a first camera and a second camera and a controller. Each camera has a field of view that overlaps partially with the field of view of the other camera. Each camera has an imager for generating a preliminary digital image. The cameras together have a combined field of view. The controller is programmed to generate a final composite digital image that corresponds to a selected digital representation of the combined field of view of the cameras by using a remapping table to remap selected pixels from each of the preliminary digital images into selected positions of the final composite digital image.
In a fourth aspect, the invention is directed to a method of generating a remapping table for use in mapping pixels from a plurality of preliminary digital images into a final composite image, comprising:
a) driving a vehicle having a first camera and a second camera thereon, each camera having a field of view that overlaps partially with the field of view of the other camera, each camera having an imager for generating one of the preliminary digital image, wherein the cameras together have a combined field of view, wherein the vehicle further includes a controller;
b) detecting a target feature along the path of the vehicle during driving, using the controller;
c) providing a first preliminary digital image from the first camera, wherein the first preliminary digital image contains a first representation of the target feature at a first point time;
d) determining the position of the first representation of the target feature in the first preliminary digital image;
e) providing a second preliminary digital image from the second camera, wherein the second preliminary digital image contains a second representation of the target feature at a second point time;
f) determining the position of the second representation of the target feature in the second preliminary digital image;
g) comparing the positions of the first and second representations of the target feature; and
h) generating at least one value for the remapping table based on the result of the comparison in step g).
The present invention will now be described by way of example only with reference to the attached drawings, in which:

The digital image generated from the image sensor 24 may be referred to as a preliminary digital image, an example of which is shown at 26 in
Each preliminary digital image 26 is made up of a plurality of pixels, which are shown at 28 in the magnified image shown in
The controller 18 is programmed to generate a final composite digital image, shown at 30 in
The digital representation may incorporate one or more operations on the original preliminary digital images 26. For example, the pixels 28 from the original images 26 may be remapped in such a way as to dewarp the images 26. As can be seen in
Another operation that may be carried out through the remapping is viewpoint adjustment. Each preliminary digital image 26 has associated therewith, an apparent viewpoint, which is the viewpoint from which the camera 16 appears to have captured the image 26. In the preliminary digital images 26, the apparent viewpoint of the camera 16 is the same as the actual viewpoint of the camera 16 because no manipulation of the image 26 has been carried out. However, it may be preferable, when presenting a 360 degree view around the vehicle to the vehicle driver, to present a bird's eye view. To accomplish this, the perspective of the image is adjusted by adjusting the relative sizes of portions of the preliminary images when remapping them to the final composite image 30. For example, the objects that are closer to the camera 16 appear larger in the image 26 than objects that are farther from the camera 16. After the apparent viewpoint has been raised however, as shown in the final digital image 30, objects closer to the camera 16 are shrunk so that they are not larger than objects farther from the camera 16.
A graphical representation of the remapping that is carried out is shown in

Aspects of the calibration of the multi-camera system 14 will now be discussed. This calibration is used in order to assist in determining the remapping values in the remapping table 32 (
Initially, the cameras 16 are mounted to the vehicle body 12 and the vehicle 10 is positioned at a location (as shown in
In the exemplary test arrangement 34 shown in
The dewarped image 44 may then be viewpoint adjusted so as to move the apparent viewpoint of the camera 16 upwards to generate a resulting ‘dewarped and viewpoint-adjusted’ image 48 in
The dewarped and viewpoint-adjusted image 48 shown in
As can be seen in
Once the four first remapping tables 46, the four second remapping tables 49 and the third remapping table 60 are generated, the remapping table 32 shown in
However, the controller 18 may additionally store one or more of the individual remapping tables for use in generating and displaying an intermediate image. For example, it may be desired to show a dewarped rear view from the vehicle 10 in some instances, such as when the driver is backing the vehicle 10 up. The preliminary digital image 40 from the rear camera 16 can be remapped quickly and easily using the first intermediate remapping table 46 to generate the dewarped rear view image 44. Other viewing modes are also possible and would benefit from having one or more of the intermediate remapping tables stored in the memory 80. For example, a split view showing images from the driver's side and passenger side cameras could be provided.
In the above example, the test arrangement 34 of landmarks 36 and 38 were provided as images painted on the floor of an indoor test area. It will be noted that other means of providing the test arrangement 34 can be provided. For example, the test arrangement can be provided on mats place on the floor of the test area. Alternatively, the test arrangement 34 could projected on the floor of the test area using any suitable means, such as one or more lasers, or one or more projectors, or some combination of both.
In the example described above, four cameras are used to generate a 360 degree view around the vehicle, using pixel remapping. It will be understood that the advantages of pixel remapping are not limited to camera systems that employ four cameras. For example, in an alternative embodiment that is not shown, the vehicle may include cameras 16 mounted at each of the front corners and each of the rear corners of the vehicle. Depending on whether the vehicle is leaving a parking spot by driving forward or by backing up, the two front corner cameras or the two rear corner cameras could be used to form a view that shows cross-traffic in front and to the sides of the vehicle, or behind and to the sides of the vehicle depending on whether the vehicle is driving forward or backing up. In such an embodiment, a final composite image can be generated using pixel remapping, but would be generated based on images from only two cameras (i.e. the cameras at the two front corners of the vehicle, or alternatively the cameras at the rear two corners of the vehicle).
It will be noted that, while the lines 38 in the test arrangement have been shown as straight lines, they need not be. They may be any suitable selected shape, which is then compared to its representation in the images 40 and 44 to determine how to remap the pixels to reduce warping and to carry out viewpoint adjustment.
In the test arrangement 34 shown in
The above description relates to the calibration of the camera system 14 in a controlled environment using a test arrangement 34 to generate the remapping table 32 for storage in the memory 80.
It may be desirable to permit the controller 18 to calibrate or recalibrate the camera system 14 during driving. To do this, the controller 18 identifies a target feature that appears in an image from one of the cameras 16. The target feature is shown in
As the vehicle 10 is driven (preferably below a selected speed) past the target feature 61, the target feature 61 moves through the field of view of the front camera 16, through the field of view of one of the side cameras 16 and finally through the field of view of the rear camera 16. A representation of the target feature 61 will thus move through images from the front camera 16, then through images from one of the side cameras 16, and then through images from the rear camera 16. By analyzing the movement of the representation of the target feature 61 (e.g. its position, its direction of travel and its speed of movement) particularly as it transitions from images from one camera into the images from a subsequent camera the controller 18 can determine X and Y offsets, angular offsets, differences in scale, and possibly other differences, between images from one camera and another. This analysis may be carried out as follows: The controller 18 may start with a default set of remapping values for the remapping table 32 to generate a final composite image 30 from the four images. This default set of remapping values may be based on a simple algorithm to crop the preliminary digital images as necessary, rotate them as necessary and scale them as necessary to fit them in allotted zones 63 (shown individually at 63F, 63R, 63D and 63P) of a preliminary composite image 65 shown in
In
While tracking the movement of the representation 69, if the controller 18 detects that the representation 69 shifts horizontally by some amount of pixels (as shown in
With reference to
With reference to
It may be that only the remapping values associated with pixels in the immediate vicinity of the representation 69 are adjusted. Thus, the vehicle 10 may drive along while the controller 18 scans for and detects target features 61 at different lateral positions on the road, so that different portions of the remapping table 32 are adjusted. As an alternative way, the vehicle 10 may drive along while the controller 18 scans for and detects multiple target features 61 at different lateral positions across each demarcation line 67. At a selected point in time (e.g., after having detected target features 61 over a selected amount of lateral positions along the demarcation line 67), the controller 18 may then determine a formula (or set of formulas) that could be used to remap the entire area along the demarcation line 67 as a whole, based on the changes in the positions of the representations 69. Then the controller 18 uses that formula (or set of formulas) to remap the entire area around the border. For greater certainty the formula or formulas may be linear or nonlinear.
After detecting a target feature 61 at a particular lateral position on the road, and adjusting a portion of the remapping table 32 through the techniques described above, the controller 18 may also scan for and detect a second target feature 61 at approximately the same lateral position on the road and apply these techniques again, in order to improve the accuracy of the adjustments to the remapping values.
In many situations (e.g. after a malfunctioning or damaged camera has been replaced in the vehicle or simply due to a shift in the position of a camera over time in the vehicle) it may be that a camera is no longer in the same position and orientation as it was before. As a result, during the calibration procedure some pixels will require a change in their remapping due to new changes that occur to representations 69 as they cross demarcation lines 67. If the changes to the remapping are only carried out in the immediate vicinity of the affected pixels then there will be a misalignment of those pixels with other pixels that are not changed. If the changes are made to all the pixels in an image 26 then this could cause a problem with the remapping of pixels at the other demarcation line 67 at the other end of the image 26. To address this issue, when a new remapping is carried out on a selected pixel, the remapping is carried out in progressively diminishing amounts on a range of adjacent pixels. For example, if during a calibration it is determined that a particular pixel should be shifted 5 pixels laterally, a selected first number of pixels longitudinally adjacent to that pixel will be shifted 5 pixels laterally, a selected second number of pixels longitudinally adjacent to the first number of pixels will be shifted 4 pixels laterally, a selected third number of pixels adjacent to the second number of pixels will be shifted 3 pixels laterally, and so on until there is no lateral shift to carry out. This effectively smooths out the remapping of the pixels, as an example, in a car wherein the front camera is damaged in a traffic accident, and is replaced, a recalibration will be carried out, and the controller 18 may detect that the remapping that applied at the front left and right demarcation lines 67 does not work anymore. The controller 18 may determine a new remapping for these regions. However, the remapping that occurs at the rear left and right demarcation lines is still good, since the left, right and rear cameras have not been moved. To address this, the controller 18 may remap some selected number of pixels (e.g. 50 pixels), rearward of the newly remapped pixels along the front left and right demarcation lines 67 in groups by progressively smaller amounts eventually reducing the remapping to zero. No remapping of pixels takes place along the rear left and right demarcation lines 67.
After a selected period of time of driving, or after detecting enough target features at enough lateral positions to ensure that a sufficient amount of adjustment of the remapping table has been made, the controller 18 may end the calibration process.
The particular cameras 16 that are used in the camera system 14 may be any suitable cameras. One example of an acceptable camera is a ReversAid camera made by Magna Electronics, an operating unit of Magna International Inc. of Aurora, Ontario, Canada.
The camera or vision system includes a display screen that is in communication with a video line and that is operable to display images captured by the camera or camera module. The display screen may be disposed in an interior rearview mirror assembly of the vehicle, and may comprise a video mirror display screen, with video information displayed by the display screen being viewable through a transflective mirror reflector of the mirror reflective element of the interior rearview mirror assembly of the vehicle. For example, the camera or camera module may be disposed at a rearward portion of the vehicle and may have a rearward facing field of view. The display screen may be operable to display images captured by the rearward viewing camera during a reversing maneuver of the vehicle.
