Definitions
- the invention relates to a method and a computer program for the graphic processing of an image of a company of a motor vehicle motor vehicle provided by a camera device, in particular in the direction of travel of the motor vehicle.
- the invention relates to a warning device for performing this method and a data carrier with the computer program.
- Warning devices of this type typically include a camera device which is installed, for example, in the rear of a vehicle in order to detect the surroundings of the vehicle in the rear area. An image recorded by this camera device is typically processed using an image editing device and then shown to the driver on a display device in the dashboard. The driver can then use the image shown to orient himself when reversing.
- This object is achieved by the method claimed in claim 1.
- This method is characterized by the following steps: detecting an obstacle in the vicinity of the motor vehicle and determining its real position, preferably relative to the position of the motor vehicle, determining the real position of the obstacle in the vicinity and the corresponding position of the obstacle in that of the Camera device provided image and performing the processing of the image taking into account the determined position of the obstacle in the image.
- the claimed method automates the process of identifying a hazard potential that arises from an obstacle for the motor vehicle that may be present in the vicinity of the motor vehicle and thus possibly also for the driver.
- the camera device itself is not able to do this. It depicts the surroundings of the motor vehicle in a neutral manner, that is to say without evaluation, on an image.
- “without evaluation” means that the camera device, in turn, has no knowledge of which parts of the image captured by it represent an obstacle in the surroundings of the vehicle and which do not. All the more, the camera device is not in a position to assess the potential hazard that may arise for the motor vehicle from this obstacle.
- the invention proposes firstly the real position of the obstacle in the vicinity of the motor vehicle, preferably relative to the position of the motor vehicle or the position of the camera device , too determine. According to the invention, this is done with the aid of an obstacle detection or distance measuring device which is based, for example, on ultrasound or radar or camera / image analysis technology. According to the invention, such a device is used in addition to the camera device. The real position of the obstacle in the surroundings of the motor vehicle determined by this is then converted according to the invention with the aid of suitable mathematical algorithms or transformations into the corresponding position of the obstacle in the image provided by the camera device.
- the real position of the obstacle in the surroundings is a three-dimensional size
- the position of the obstacle in the image is a two-dimensional size
- the transformation applied in each case then performs a corresponding conversion from, for example, a three-dimensional to a two-dimensional position.
- the image provided by the camera device is processed with knowledge of the previously determined position of the obstacle in the image provided by the camera device.
- the image can now be processed in a very targeted manner for the viewer, in particular the driver of the motor vehicle, in such a way that it is particularly clear on the obstacle itself, but also on the danger potential for the motor vehicle from this obstacle, for example in the form of Size of the distance between the motor vehicle and the obstacle is pointed out.
- a graphic object in the form of the expected lane course, on which the vehicle is likely to move in the near future is faded into the image of the camera device.
- the distance between the obstacle and the motor vehicle determined according to the invention is advantageously used to limit the overlaid course of the lane in such a way that the graphic object does not overlap with the obstacle depicted in the image.
- a graphic object in particular a bar, is proposed which enables this information to be transmitted over the spatial area in addition to the distance. All graphic objects presented in the context of the invention are advantageously shown semi-transparent or only as outlines so as not to hide the parts of the image of the camera device located at the respective position of the graphic object.
- the graphic object can also be designed such that it at least partially covers these parts.
- the graphic objects can then be represented as colored surfaces, the coloring optionally being able to be varied in accordance with the determined distance of the obstacle from the motor vehicle or from the camera device.
- the image supplied by the camera device is processed by fading in or superimposing the aforementioned graphic objects. It is also conceivable that instead selected parts of the image provided by the camera device are directly manipulated, for example brightened or colored. The selected parts are preferably those areas from which it is known from the information supplied by the obstacle detection or distance measuring device that they represent the obstacle. The manipulations carried out directly in the image provided by the camera device are also advantageously varied in color according to the size of the currently determined distance between the obstacle and the motor vehicle.

- a delimitation device such as a barrier, a gate or a fence.
- an overlay of the graphic object 210 with the obstacle 100 can exceptionally be accepted without the Driver is too irritated by this; in principle, however, such an overlay should be avoided.
- the delimitation line 212 and / or the delimitation device 214 particularly clearly illustrates the risk of collision emanating from the obstacle 100 to the viewer of the image, in particular to the driver of the motor vehicle. In this way, he is given a clear understanding that if he drives the motor vehicle beyond the limit, a collision with the obstacle 100 will inevitably occur.
- FIG. 4 shows a second exemplary embodiment for the design of the graphical object 210 representing the course of the lane. Instead of not showing this course beyond the boundary 212, 214, as shown in FIG. 3, it may be advantageous to move the course of the lane beyond it To show the limitation, that is to say for greater distances from the motor vehicle 400, in dashed lines; see reference number 210 '.
- the first exemplary embodiment shown in FIG. 3 can also be combined with the second exemplary embodiment shown in FIG.
- the obstacle detection / distance measuring device 320 often also offers the possibility of determining in which area of the space it detects, the obstacle 100 is located. For example, a distinction can be made as to whether an obstacle is located essentially to the left of the camera device 320, exactly opposite it or to the right of the device 320. These three possible spatial areas are shown in FIG Reference numerals I, II and III designated.
