Definitions
- the invention relates to a device for surface inspection of a motor vehicle and a method for surface inspection of a motor vehicle.
- An optical inspection is carried out on motor vehicles for various reasons. For example, after a hail event, an optical inspection of a motor vehicle surface may be necessary in order to be able to detect any damage caused by hailstones or the like. However, a surface inspection is also necessary to check the success of a repair to be carried out subsequently, for example using the smart repair method. In addition to environmental influences, other sources of damage, such as parking dents or the like, can also be considered. A time-consuming and often not very objective procedure is also the inspection of vehicle surfaces, for example after the termination of a leasing contract, which are used to determine a vehicle's value and, depending on the point of view, can lead to different valuations.
- EP 0 405 806 B1 describes a method for checking the surface of a part, in which the part is set up at a test site, light on the surface at a large angle of incidence with respect to the surface normals is directed to create a cross-beam trace thereover and to reflect light at a low deflection angle, thereby forming an image of the beam trace on a display screen and taking a picture of the image and scanning the light with respect to the part to provide further cross-beam traces over the To form part.
- a light beam trace is made on the surface in a substantially perpendicular direction to this top viewed area and a recording of this beam trace is generated, the recording of this image and the recording of the beam trace being analyzed together in order to show the nature of the surface on the beam trace.
- the steps viewing, scanning and recording are repeated for the new beam traces.
- WO 98/05588 A1 presents a method for surface inspection in which a light beam emanating from a light source is sent via a surface to a reflector. The light beam then takes the same light path back over the surface and is finally recorded on a recording device.
- This is an optical refractometer with which surface irregularities can be determined.
- EP 1 464 920 A1 discloses a device for detecting, determining and documenting damage caused, for example, by hailstorms on vehicle surfaces.
- the device comprises a light source, from which light rays are reflected over the surface of the vehicle to be examined and the rays are then imaged on a screen.
- On the side of the screen facing away from the vehicle is a camera that records the image of the rays reflected from the surface on the screen.
- the image data from the camera are fed to an evaluation system, which then detects surface irregularities.
- the camera, screen and light source are mounted on a common support frame. The vehicle to be examined is placed on a measuring table.
- a device for surface inspection of a motor vehicle is accordingly created, in which a plurality of line lasers, at least one reflector shield and at least one camera is provided.
- a large number of line lasers are used here, which cover the area to be inspected with a line-shaped beam.
- they can be designed with different colors in certain embodiments.
- the different line lasers can be distinguished from one another at least in some areas, which can also be achieved by an offset arrangement on the reflector plate.
- the line lasers used can have a small opening angle, so that the reflector shield can be chosen to be relatively compact with regard to its extension.
- the line lasers are mounted on a swivel device so that they can be tracked accordingly.
- An evaluation unit compiles this information to assess the surface to form an image, so that no comparison with a sample body or the like has to be carried out. In other versions, however, a comparison with a sample body can still be made as an option.
- lasers with a relatively low power for example with a power of 50 mW or less, can be provided as line lasers, so that the device according to the invention can be implemented cost-effectively.
- the line lasers are adapted accordingly, so that the associated image is centered on the reflector plate by pivoting the line laser via the pivoting device.
- the device can thus be adapted to any surface of a motor vehicle.
- the camera and the line laser can be arranged on an adjustable measuring arrangement, the measuring arrangement being adjustable with respect to a distance from the surface of the motor vehicle.
- This embodiment makes it possible to create an appropriate adjustment option in the case of different body shapes, so that the camera covers the area to be examined.
- the measuring arrangement can be displaceable over the motor vehicle along a longitudinal direction, in particular the measuring arrangement in the form of a portal can be moved over the motor vehicle. The vehicle can also be moved through a fixed measuring frame
- the line lasers irradiate both the top of the motor vehicle and the side surfaces of the motor vehicle with laser radiation.
- parts of the undercarriage or the underbody can also be included in the optical inspection.
- the line laser and the image reflected by the reflector shield have an angle relative to the surface of the motor vehicle.
- the measuring unit with reflector plate can also be swiveled by an angle of ⁇ 120 °.
- the images captured by the camera are analyzed in real time by a powerful evaluation computer.
- the software can intelligently interpret and measure the laser reflections. This makes it possible to identify dents, scratches, paint damage, glass damage, hail dents, stone impact and an assessment of the paint quality (orange peel), the degree of gloss and the type of paint (metallic) possible.
- the above-mentioned object is also achieved by a method for the surface inspection of a motor vehicle, in which the device according to the invention can be used.

- FIG. 8 shows a further embodiment of the invention in a perspective side view
- Fig. 9 shows the embodiment of Fig. 8 in a plan view.
- a device VO according to the invention is shown in a perspective side view in FIG. 1.
- the device VO is suitable for recognizing one or more defects in an area BE to be inspected, for example in the form of Dellen DE.
- several line lasers are provided, which are designated by way of example with LL1, LL2 and LL3 according to FIG. 1. In other applications, however, it is conceivable to use further line lasers.
- the line lasers LL1, LL2 and LL3 are each mounted on a swivel device SW, so that the angle of incidence with respect to a surface OF of a motor vehicle KF can be changed.
- the light rays reflected from the surface OF are recorded by a camera KA via a reflector shield RS.
- the propagation of the linear beams emitted by the line lasers LL1, LL2 and LL3 is shown more clearly in a side view in FIG. 2A.
- the first laser beam LL1 emits a first light beam LS1, which is reflected from the surface OF to the reflector shield RS in accordance with known optical laws.
- a second laser beam LS2 is reflected by the second line laser LL2 and a third line-shaped beam LS3 by the third line laser LL3.
- the camera KA In order to use the camera KA to produce an image that is as adapted to the resolution of the camera as possible, it is possible to individually adjust the first line laser LL1, the second line laser LL2 and the third line laser LL3 via the swiveling device SW, which both can be selected depending on the distance of the line lasers LL1 to LL3 to the surface OF as well as their curvature. Because of this procedure, it is possible to arrange the camera KA unchanged relative to the line lasers LL1 to LL3 and relative to the reflector shield RS, so that the adaptation to different surface geometries is only possible via the
- Possibility of swiveling can be done by means of the swivel device SW.
- 2B shows the propagation of the linear beams emitted by the line lasers LL1, LL2 and LL3 is shown in a top view.
- the individual lines of the line lasers LL1, LL2 and LL3 are designated on the surface OF of the motor vehicle KF with LL1 ', LL2' and LL3 '. It can be seen that the lines LL1 ', LL2' and LL3 'of the respective line lasers LL1, LL2 and LL3 overlap slightly in the transverse direction with respect to the surface OF of the motor vehicle KF, so that the surface OF of the motor vehicle KF can be scanned completely when the motor vehicle KF is moved relative to the line lasers LL1, LL2 and LL3.
- the laser lines LL1 ', LL2' and LL3 'reflected by the surface OF of the motor vehicle KF are recorded via the reflector shield RS by one or more cameras KA and fed to an evaluation unit not shown in FIG. 2B.
- the line lasers LL1, LL2 and LL3 and the cameras KA can be arranged on a measuring arrangement MA and can be pivoted with respect to this.
- At least a pivotability of the line lasers LL1, LL2 and LL3 about an axis in the sheet plane essentially parallel to the longitudinal axis of the measuring arrangement MA is preferably provided, so that the angle of incidence on the surface OF of the motor vehicle KF can be changed so that the Laser lines LL1 ', LL2' and LL3 'reflected from the surface OF of the motor vehicle KF hit the reflector shield RS.
- the pivotability of the line lasers LL1, LL2 and LL3 will therefore be varied depending on a curvature of the surface OF of the motor vehicle KF.
- an adjustable measuring arrangement MA which carries the camera KA, the line lasers LL1, LL2 and LL3 and the reflector shield RS.
- the measuring arrangement MA (shown enlarged in FIG. 3B) can be set with respect to a distance AB from the surface OF of the motor vehicle KF. As a result, it is possible to place the measuring arrangement MA appropriately depending on the body shape of the motor vehicle KF.
- the measuring arrangement MA shown in FIG. 3B would cover an upper side of the motor vehicle KF, so that defects in the form of dents DE can be measured in the area BE to be inspected.
- the distance AB of the measuring arrangement MA and the angle of incidence of the line lasers LL1, LL2 and LL3 which can be controlled by means of the swivel mechanism SW can be adapted to the body shape of the motor vehicle KF in different ways.
- an optical inspection (indicated in FIG. 3B by means of the control device ST) can be carried out, which can be carried out with a camera or other line lasers to detect the curvature of the surface OF of the motor vehicle KF.
- both the roof surfaces and, for example, the front and rear parts of a motor vehicle KF can be inspected by means of the device VO according to the invention.
- FIGS. 4A and 4B show a further embodiment of the device according to the invention, in which, in addition to the measuring arrangements MA and MA 'described so far, other measuring arrangements MA "are also provided, which cover both the front and the side surfaces of the device Motor vehicle KF can measure.
- gap dimensions of the body or the position of the wheels and axles can also be measured, so that, for example, chassis damage can be identified by determining the track or camber.
- the laser lines LL1 ′′, LL2 ′′ and LL3 ′′ reflected by the surface OF of the motor vehicle KF are controlled via the swivel mechanism SW with respect to their angle of incidence on the surface OF of the motor vehicle KF and their distance AB to the surface OF of the motor vehicle KF.
- the laser lines LL1 ′′, LL2 ′′ and LL3 ′′ are arranged in their edge areas to overlap the neighboring laser line. Adjacent laser lines are of different colors to facilitate assignment on the RS reflector plate.
- the line lasers LL1, LL2 and LL3 emit laser lines LL1 ', LL2' and LL3 'with a small opening angle, so that a correspondingly narrow line is generated on the surface OF of the motor vehicle KF.
- the corresponding image on the reflector shield RS is shown in Fig. 5B.
- the laser line LL2 ', in the current example on a dent DE in the image LL2 “on the reflector plate RS shows a clear deviation from the line shape.
- FIG. 6 An example of an automatic evaluation of dents DE after a hailstorm is shown in FIG. 6 below.
- the images recorded by the karmas KA according to FIG. 5B are transmitted to an evaluation unit, not shown in the figures, which is provided, for example, in the form of a corputer.
- the images obtained are shown schematically in Fig.
- the automatic detection of defects can, for example, carry out a classification so that an extent and a depth of the dents DE can be quantified. Such information can be helpful both for the removal of hail damage, for example by means of a smart repair method, or for the quantification of repair or insurance services.
- FIG. 7A shows the corresponding device in a sectional view
- FIG. 7B shows a plan view of the device VO.
- the device VO has a housing GE which essentially has a square cross section, but the housing GE is open on one side. This side also forms the underside of the device VO in the illustration according to FIG. 7B.
- a plurality of line lasers LL and cameras KA are arranged in the interior of the housing GE on the side wall immediately adjacent to the opening. Adjacent line lasers can again have different colors and overlap in pairs.
- the line lasers LL emit light in the direction of the opening, while the cameras KA record the reflected light from the opposite side of the housing GE.
- the device VO is not moved over the vehicle, but is placed, for example, on an auxiliary device that is not shown in FIGS. 7A and 7B, so that the device VO has a fixed height with respect to the motor vehicle, so that it subsequently has a handle GR can be pushed over the surface of the motor vehicle.
- it is provided, for example, to attach two measuring wheels MR to the opposite ends, by means of which a corresponding distance measurement can be carried out.
- Such a device VO can be used, for example, by insurance field staff to quantitatively record hail damage or general body and glass damage.
- the device VO shows a further embodiment of the device VO.
- the device VO according to the invention is shown in a perspective side view together with the motor vehicle KF.
- the device VO in turn has the swivel device SW, which according to this exemplary embodiment consists of an upper part OT and a lower part UT.
- the lower part UT can be aligned relative to the motor vehicle KF via a first axis of rotation DA1 and a second axis of rotation DA2.
- the first axis of rotation DA1 is oriented parallel to a driving plane of the motor vehicle KF and perpendicular to a direction of forward travel of the motor vehicle KF.
- the second axis of rotation DA2 is oriented perpendicular to the driving plane of the motor vehicle KF.
- the lower part UT has a frame RA which is provided with a plurality of spacers AB.
- the reflector shield RS is arranged at the other ends of the spacers AB, so that its dimensions correspond approximately to those of the frame RA and are rectangular.
- the reflector shield RS is made in three parts, a partially transparent region being arranged on each of the two long sides.
- the first partially transparent area TT1 and the second partially transparent area TT2 each serve to record an image of line-shaped rays which are reflected by the surface OF of the motor vehicle KF and are generated by means of line lasers (not shown in FIG. 8) and by a camera (also not shown) one opposite the surface OF of the motor vehicle KF opposite side in the partially transparent areas TT1 and TT2 on the reflector plate RS.
- a fully transparent area VT is arranged between the first partially transparent area TT1 and the second partially transparent area TT2, through which, for example, a line laser can guide the linear beams onto the surface OF of the motor vehicle KF.
- the reflector shield RS can be formed, for example, by a glass plate which is glued over accordingly to create the partially transparent areas TT1 and TT2 outside the fully transparent area VT.
- the first partially transparent area TT1 and the second partially transparent area TT2 can also be provided individually as frosted glass panes, these leaving the area VT open.
- FIG. 9 shows the embodiment from FIG. 8 again in a top view.
- three line lasers LL1, LL2 and LL3 cover the area to be inspected on the surface OF of the motor vehicle KF with a line-shaped beam LLT, LL2 'and LL3'.
- the camera KA can be seen, but in other embodiments it can also be replaced by a large number of cameras.
- the image of the line lasers LL1 and LL3 will come to lie in the second partially transparent area TT2, while the image of the line laser LL2 is arranged in the first partially transparent area TT1.
- the respective images of the line lasers would not be shown in FIG. 9 for the sake of simplicity.
- the further advantage of the exemplary embodiment described in connection with FIGS. 8 and 9 is that the line lasers LL1, LL2, and LL3 do not necessarily have to be pivoted individually. Since the distance of the lasers LL1, LL2, and LL3 from the surface OF of the motor vehicle KF remains almost constant, the sharpness and brightness do not change or change only slightly.
- the device VO is closer to the surface OF of the motor vehicle KF, as a result of which external light influences or light reflections are reduced or can even be completely avoided by a cover. Due to the alternating arrangement of the different lasers in the first partial area TT1 and second partial area TT2, the reflected laser lines do not overlap or only overlap, and a better separation can be achieved. Furthermore, the surface OF of the motor vehicle KF can also be checked for matt surfaces that do not reflect using normal laser triangulation. Furthermore, the camera KA can have several functions, since in addition to the direct three-dimensional evaluation via laser triangulation, it is also possible to evaluate the reflection.
