Definitions
- the invention relates to a method for scanning a body element for a motor vehicle.
- the invention relates to a scanning device for scanning a bodywork element for a motor vehicle.
- Body parts are repeatedly tested in the production of a motor vehicle to detect and correct errors or damage to the body or to take the body element from the production process. While a large number of these checks, in particular the detection of large-scale deformations, is already carried out automatically, a final check of the body takes place by a hand-held feel. In this very delicate even the smallest defects of the body can be detected.
- the surface to be scanned In order to achieve reliable scanning, the surface to be scanned must be completely sensed and a certain minimum pressure must be applied to each area of the surface to detect any imperfections. In a manual scanning, however, it is hardly possible to understand the sensing path and in particular the pressure applied to the scan. This is on the one hand hinders the training of the scanning persons, since they can be given no direct feedback. On the other hand, quality control of the sensing process carried out in the context of production is only possible by randomly sampling body elements by several persons.
- the invention is therefore based on the object to improve the traceability and / or repeatability of a scanning of a body element.
- the object is achieved by a method of the type mentioned, in which a pressure measuring film is arranged with matrix-like pressure measuring sensors for spatially resolved detection of pressure readings ah the body member or on a scanning element, and comprising the following steps:
- Output of a feedback information by an output device wherein a time of the output of the feedback information and / or a content of the feedback information is determined by the detection device as a function of the detected at the measurement points position information and pressure readings.
- both the respective position information which describes a position of the scanning element
- the pressure measured values of the pressure measuring sensors are detected at several measuring times, for example with a fixed timing. It therefore makes it possible to understand the sensing path, including the applied pressure. Since the detection of position and pressure takes place automatically, the method can also be developed in such a way that a scan is fully or partially automatic. This will be shown later in more detail.
- the method according to the invention can be used to train persons for scanning. For example, a feedback information can be output if a certain area to be scanned was not completely scanned during the scan or was not scanned with a sufficient pressure. It is also possible to give the person to be trained feedback on how far a given Sollabtastweg was followed, how fast a scan was made or the like.
- the method can also be used for manual sampling in the production process for quality control. Due to the traceability of the sensing path and the applied pressures, a manual scanning, which differs from certain specifications, can be easily detected and it can be issued an indication to the person to be scanned.
- the determination of the position information and the pressure measurement values can be carried out continuously with a predetermined timing or only upon contact of the pressure measurement film with the body element and the sensing element, for example upon detection of a predetermined minimum pressure on the pressure measurement film.
- the sensing element may be a hand of a person being scanned. However, it is also possible to use a mechanical scanning element which is guided via actuators and / or manually by a scanning person.
- the feedback information can be output visually and / or acoustically and / or haptically.
- the feedback information may include information about a shape of the body element, in particular a deviation from a desired shape, information about individual surface defects and / or parameters of the scan.
- a parameter of the scanning for example, a scanned area, in particular a range scanned with a minimum pressure, pressures applied during the scanning, a scanning speed, preferably as a scanned area per time, and / or a scanning pattern which describes the scanning path of the scanning element, be included in the feedback information.
- an indication may be issued if during the scanning a predetermined minimum pressure is exceeded, deviated from a Sollabtastpfad, a predetermined Sollabtast bien is exceeded, is determined from the pressure measurements that the sensing element is guided on or over a surface defect and / or a scan has been completed with a surface to be scanned not scanned completely.

- values for a minimum, a maximum and / or a desired pressure can also be predetermined, wherein the sensing element can be guided perpendicular to the body element in accordance with these pressures.
- An adaptive scan path can be implemented, for example, by specifying an initial scan path, but superimposing it on a pressure-dependent control for at least one of the degrees of freedom.
- a scanning element can be used which has an elastic, in particular flat, surface to which the pressure measuring film is applied.
- the pressure measuring film may be firmly applied, so that the sensing element and the pressure measuring film form a structural unit.

- the position sensor can detect rotations at joints and / or displacements in guides of the bearing, from which, with a known design of the bearing, a position and / or orientation of the sensing element with respect to the body element can be determined.
- At least one temporal and / or spatial pressure gradient can be ascertained by the detection device for each time an output of the feedback information is triggered by at least one of the pressure gradients at a measurement time and / or the feedback information contains the position information for this Measuring time or derived therefrom information includes. Sudden local or temporal pressure changes and thus high pressure gradients may be due to local surface defects. Detection of these pressure changes can be used to detect local defects and either to give an indication to a person being scanned immediately upon detection of the defect or to record the position at which that local defect was detected. A pressure gradient can be calculated by subtracting spatially or temporally adjacent pressure readings from each other.

It can be further developed with the features relating to the scanning device, which have been explained for the method according to the invention, with the advantages mentioned there. Likewise, the inventive method can be further developed with features that are explained below to the scanning device according to the invention.
- the scanning device may comprise the scanning element.
- the pressure measuring foil can be applied to an elastic, in particular flat, surface of the scanning element.
- an arrangement of the pressure measuring film on the scanning device is advantageous because the pressure measuring film does not have to be mounted on each of the body elements to be examined.
- a particularly simple structure can be used when the pressure measuring film is arranged on the body element, since in this case, as explained for the method according to the invention, the position information can be determined directly from the pressure measurements.
- the scanning device may comprise at least one actuator for moving the scanning element, wherein the actuator is controllable by the detecting device for movement along a scanning path.
- a plurality of actuators may be provided.

- the scanning element is to be guided along a predetermined scanning path over a surface of the body element.
- the scanning element is moved along a section of the scanning path along the contour of the body element in step S2.
- a position information concerning the position of the scanning element is determined.
- the position information can be obtained directly from the control information for the six-axis robot.
- the pressure readings are acquired and the position information and pressure readings are stored for that time of measurement.
- step S4 a plurality of spatial gradients are calculated during the first execution for the first measurement time.
- temporal pressure gradients are determined. Pressure gradients are determined for the individual pressure measuring sensors both in a longitudinal direction and in a transverse direction of the plate-shaped sensing element. Local pressure gradients are determined by subtracting pressure readings from adjacent pressure sensing sensors.
- temporal pressure gradients can be calculated by measuring the pressure readings for each of the pressure measuring sensors for successive measuring times. be subtracted from each other.
- the pressure measured values may first be transformed into a coordinate system fixed relative to the body element, wherein a pressure measurement value is assigned in each case to a surface region of the body element. The pressure readings determined for such a range at successive measurement times can be subtracted from one another to determine a temporal pressure gradient.
- step S5 it is checked whether one of the determined pressure gradients is greater than a predetermined gradient limit value. If this is the case, the position information is stored in an additional data structure in step S6, since an occurrence of high spatial or temporal pressure gradients indicates a surface defect.
- the data structure thus provides a list of positional information describing locations of possible surface defects.
- step S7 it is determined whether the scan has been completed, that is, whether all measurement points of a scan path have been traveled. If this is not the case, it is checked in step S8 whether it is necessary to adapt the future scan path. This is required when the largest of the pressure readings exceeds a predetermined first pressure limit, in which case the sensing element is to be withdrawn slightly from the body member to reduce the pressure on the body member. Even in cases where the maximum pressure reading is less than a predetermined second pressure limit, an adaptation of the scan path is required because a certain minimum pressure is to be applied for reliable scanning of the body member.
- An adaptation of the scanning path is also carried out when a measure of an asymmetry of the pressure distribution on the pressure measuring film exceeds a predetermined limit, as this indicates an oblique position of the plate-shaped sensing element relative to the contour of the body element. If one of the mentioned conditions is met, the predetermined scanning path is adapted in step S9. Depending on the fulfilled Condition is a movement of the sensing element in the direction of the body member or away from the body member and / or tilting of the plate-shaped sensing element. After or in the case where no adaptation of the scanning path is required, the method is continued from step S2.
- step S10 the scanning element is moved away from the body element and an output device issues a feedback information to a user or to control further processing steps.
- the feedback information includes the position information that was stored when the spatial and / or temporal pressure gradient was greater than the gradient threshold.
- the feedback information can describe a detected shape of the scanned surface or partial surface of the body element and / or a deviation from a predetermined desired shape.
- the feedback information may include data describing a scan pattern, the scanned area, minimum pressures that were scanned, a scan speed, or the like.
- Fig. 2 shows another embodiment for scanning a body element.
- the method used in FIG. 2 can be used to train persons for manual scanning of body elements. However, it can also be used to support a quality control scan.
- a pressure measuring film which has pressure measuring sensors arranged in the form of a matrix, is attached to the body element. This is done by the pressure measuring film is placed on the body member and is then fixed by generating negative pressure between the body member and the pressure measuring film with respect to the surface of the body member.
- step S21 a calibration element is placed on defined areas of the body member on the pressure measuring film and these calibration points detected by the detection device.
- the detection of the calibration points in the further method allows the transformation between the coordinate system of the pressure measuring film and thus the positions of the individual pressure measuring sensors in a coordinate system defined with respect to the body element.
- step S22 the scanning process begins by a person touching his hand with a predetermined minimum pressure on the pressure measuring film and thus hangs on the body member. As soon as a predetermined minimum pressure is detected, a time measurement is started.
- step S23 pressure measurement values are then repeatedly recorded for a plurality of measurement times in order to enable a subsequent evaluation of the scanning process, and in certain scanning situations, information is output to the person to be scanned.
- the pressure measured values of the individual pressure measuring sensors are read out in step S23.
- a position information which describes the instantaneous position of the hand with respect to the body element is determined from the pressure measured values.
- a position of the hand in the coordinate system of the pressure measuring film is determined by averaging position vectors of the pressure measuring sensors, at which a predetermined minimum pressure is determined, weighted by the respectively measured pressure measured values.
- the position of a "center of gravity" of the pressure distribution is thus determined
- a coordinate transformation then ensues into the coordinate system of the body element in order to provide the position information.
- step S24 and S25 spatial and temporal pressure gradients are calculated and compared with gradient thresholds as explained for steps S4 and S5 in FIG. If it has been determined that a gradient limit has been exceeded by at least one pressure gradient, then in step S26 the current position information is stored in order to identify a position of a possible defect.
- a feedback information can be output to the user. ben that the momentarily scanned area has been recognized as an area having a surface defect. This is particularly beneficial in early training phases to alert users to what a palpation of a surface defect feels like.
- the feedback information is output as a signal tone.
- step S27 it is checked whether all detected pressure measured values are below a predetermined minimum pressure. If this is the case, a corresponding feedback information is output to the operator in step S28. Since a certain minimum pressure is required for reliable sensing of the body member, operators should be trained to always apply this during the scanning process. By issuing a feedback information, for example a corresponding warning tone, the person being scanned immediately receives feedback if it does not fulfill this requirement.
- step S29 it is checked if the scanning is finished. This is the case, on the one hand, when a predefined setpoint area has been completely scanned, that is to say if at least one pressure was detected for each area of the setpoint area which is above a minimum pressure and, on the other hand, if a predefined maximum sampling time has been exceeded. If neither is the case, then the method continues from step S23. Otherwise, in step S30, an outputting information is output by an output device concerning the sampling operation. This includes, if the target area has been completely scanned, the required time, and otherwise the non-scanned area of the target area. The non-scanned area may preferably be visually displayed.
- a scan pattern describing a movement of the hand during the scan may be displayed or it may be compared with a target pattern and deviations thereof may be displayed.
- a scanning speed in particular as area per time, can also be output as part of the feedback information.
- an image of the body element may be displayed on which the positions described by the position information stored in step S26 are marked, at which a pressure gradient limit has been exceeded, so these positions are likely to have surface defects.
