Definitions
- Automatic bulk material sorting enables the use of digital image acquisition and image processing to separate high-throughput solids into distinct fractions (such as good and bad fractions) using optically detectable features.
- belt sorting systems which use cellular imaging sensors (eg line scan cameras) for image acquisition.
- the image acquisition by the line sensor takes place on the conveyor belt or in front of a problem-adapted background and synchronous to the tape movement.
- the removal of material from a fraction is generally carried out by a pneumatic blow-out unit or by a mechanical ejection device (cf., for example, H. Demmer "Optical Sorting Systems", BHM No.
- Conveyor belt material transport can also be done by free fall or in a controlled air flow. Due to structural limitations as well as the required computing time for the image evaluation in a computer, the observation time of an object to be rejected, which is referred to below as t 0 , do not coincide with the discharge or Ausblasus.
- the blow-out unit is therefore spatially separated from the line of sight of the line scan camera. For a correct discharge of a bad object, therefore, the blow-off time (hereinafter referred to as tb or, as estimated, tb) and also the position of the object to be knocked out (hereinafter referred to as Xb (tb) or, as estimated, as Xb (tb) is estimated).
- the bold "x" characterizes that it is generally a multidimensional spatial position, with the designation x being used as an alternative thereto in the following, however, the estimates made in the prior art assume that the object to be bled out does not have its own relative motion having the band and thus moves with the velocity vector Vband the conveyor belt.
- the Ausschleusungszeittician tb and the Ausschleusungsort Xb (tb) are then passed through a linear prediction based on the speed vector of the conveyor belt Vb of d and the measured object position x (t 0) at time of observation t 0 estimated.
- their positions can also be determined at different times. As a rule, however, the same points in time at which their respective positional positions are determined are selected for all objects (the times are, for example, determined by the time of the
- Capture camera images of an optical capture unit of the system specified For different objects, the defined points in time, for each of which the location of the respective object is calculated (based on the location positions already associated with this object), may be different. However, the respective whereabouts can also be computable or predictable for one and the same later date for all detected objects. According to the invention, a prediction is thus made possible in order to estimate the spatial position of each detected object at a point in time - as seen from the time of the last spatial position determination of this object - in the future.
- the individual objects can be subjected to image processing methods known per se to a person skilled in the art (for example, a captured camera image of the objects can undergo image preprocessing such as edge detection and segmentation is subsequently performed) in (usually digital) generated during optical detection.
- Image recordings of the material flow or the objects are localized therein, identified and distinguished from each other, to determine the spatial positions of a defined object at the different times and thus to track the path of this object (object tracking).
- a movement path for the object can be determined for each object from the spatial positions of this object determined at different times. For example, on the basis of this movement path, the future location can then be estimated or calculated (if appropriate, on the basis of a movement model determined or selected with the movement path or the individual object positions at different times for the object being viewed).
- the individual objects in the material flow can be identified and based on the position of an object repeatedly determined at different times, its location can be determined with high precision at a point in time in the near future (for example shortly after leaving the conveyor belt at the level of the blow-out unit).
- the conveyor system according to the invention may have a conveyor unit, which may be a conveyor belt.
- the determination of such movement paths is also referred to below as "object tracking.”
- the movement paths are preferably determined computer-aided in a computer system of the conveyor system, that is to say microprocessor-based.
- a motion model selected for an object can serve to model future object movements of this object.
- the movement models can be stored in a database in the memory of the computer system of the conveyor system.
- Such a motion model may include equations of motion, their parameters by regression methods (for example least-squares method, least-squares-fit) or by a Kalman filter extended by a parameter identification on the basis of the specific positional positions or the particular motion path of the respective object are determinable. It is possible to select the movement model only after the presence of all recorded and determined during the optical detection position positions of an object.
- the movement model can be selected or changed in real time during the recording of the individual images for successive determination of the individual location positions (ie, while the individual image recordings are still being performed, it is possible to switch to another movement model for the object being viewed if, for example, a fit method shows that this other movement model more accurately reflects the movement of the object).
- the classification does not have to be based on or using the spatial positions determined during the optical detection (in particular: from the successive camera shots) (even if the information On the specific location positions can be advantageous in the classification, see also below).
- the classification of an object identified on the basis of its location positions at different points in time or movement path can also be carried out purely on the basis of geometric features (eg outline or shape) of this object, the geometrical features being determined by suitable image processing methods (eg image preprocessing such as edge detection with subsequent segmentation ) can be determined from the images obtained during the optical detection.
- the classification can take place in exactly two classes, a class of good objects and a class of bad objects (which are to be removed).
- the classification can thus be done on the basis of the optical recording of recorded images of the objects, by evaluating these images with suitable image processing methods and thus, for example
- Object shape, object position and / or object orientation is determined at different times.
- the pose or spatial position of an object is understood as the combination of its spatial position (or the position of its center of gravity) and its orientation. This may be a two-dimensional position (for example relative to the plane of a conveyor belt of the conveyor system - the coordinate perpendicular to it is then ignored) but also a three-dimensional position, ie the spatial position and orientation of the three-dimensional object in space.
- the particular two-dimensional spatial position is preferably the position in the plane of a moving conveyor belt, but relative to the immovable elements of the conveyor system.
- a position determination can be made in the immobile world coordinate system in which not only the immovable elements of the conveyor system rest
- the optical detection device camera.
- this orientation information determined in this way can be used to calculate the whereabouts at the defined time (s) after the latest of the different times.
- the specific orientations can also be included in the determination of the movement paths.
- the determination of the movement model (s) and / or the classification of the objects can also take place with the additional use of the determined orientation information.
- the surface sensor (s) may in particular be a camera (s).
- a camera Preferably CCD cameras can be used, also the use of CMOS sensors is possible. Further advantageously realizable features are described in claim 8.
- the shape of this / these objects (s) can be determined via image processing measures (eg image preprocessing such as edge detection with subsequent segmentation and subsequent object tracking algorithm).
- image processing measures eg image preprocessing such as edge detection with subsequent segmentation and subsequent object tracking algorithm.
- the dreidi- Mental image of an object can be obtained by suitable algorithms
- FIG. 1 shows a basic example of a system according to the invention for bulk material sorting using a conveyor system according to the invention.
- FIGS 2 to 4 the operation of the system shown in Figure 1 for calculating the future location of objects of the material flow.
- Figure 5 shows the basic structure of another plant for bulk sorting according to the invention.
- the plant for bulk material sorting shown in FIG. 1 comprises a conveyor system with a conveyor unit 2 embodied here as a conveyor belt, an area camera (CCD camera) 3 positioned above the unit 2 and at the discharge end of the same and flat illuminating means 5 for the (FIG Illumination of the field of view of the area camera.
- the image acquisition by the surface sensor (camera) 3 takes place here on the conveyor belt 2 or in front of a problem-adapted background 7 and takes place synchronously to the belt movement.
- the system also includes a sorting unit, of which only the Blow-out unit 4 is shown. Shown is also a computer system 6, with which all the calculations of the system or the conveyor system described below are performed.
- the individual objects O1, O2, O3 ... in the material flow M are thus transported by means of the conveyor belt 2 through the detection area of the camera 3, where they are recorded and evaluated in terms of their object positions by image evaluation algorithms in the computer system 6. Subsequently, the blow-out unit 4 separates into the poor fraction (poor objects SOI and SO 2) and into the good fraction (good objects GO1, G02, G03
- an area sensor (area camera) 3 is thus used.
- the image is obtained on the bulk material or material flow M (or the individual objects Ol, ... of the same) by the camera 3 on the conveyor belt 2 and / or against a problem-adapted background 7.
- the image pickup rate is adapted to the speed of the conveyor belt 2 or synchronized by a position encoder (not shown).
- the acquisition of an image sequence (instead of a snapshot) of the bulk material stream at different times (in quick succession) is aimed at by means of a plurality of surface scans or surface images of the material stream M through the area camera 3 as follows (compare FIGS. 2 to 4).
- Figure 2 the field of view 3 'of the camera 3 on the conveyor belt 2 with the bulk material or the objects thereof O is shown in plan view ( Figure 1 outlines this field of view 3' of the camera 3 in side view).
- the discharge takes place through the blow-out unit 4 (whose blow-out area 4 'is shown in plan view in FIG. 2).
- the material transport could also take place in free fall or in a controlled air flow (not shown here) if the units 3 to 7 are repositioned accordingly.
- the data acquisition can thus be based on one (or more) imaging surface sensors such as the area camera 3.
- imaging surface sensors such as the area camera 3.
- Imaging sensors outside the visible wavelength range and imaging hyperspectral sensors can also be used as imaging surface sensors.
- the position determination can also be carried out by one (or more) 3D sensor (s) which can / provide position measurements of the individual objects in space instead of in the plane of the conveyor belt 2.
- a predictive multi-object tracking can be used in the present invention.
- the object positions x (t) (x (t), y (t)) in the Cartesian coordinate system x, y, z (with the xy plane as the plane in which the conveyor belt 2 moves) at several different times t are measured.
- each movement paths by juxtaposition of each detected and determined object positions x.
- This is shown in FIG. 2 with the movement path 1 for a single object O for its movement between the times t_ 5 and t 0 , between which this object has been detected in the detection area 3 'of the camera 3 by individual image recordings.
- the observed movement path 1 is x (t 0 ), x (ti), x (t_ 2 ), x (t_ 3 ), ...
- the residence can be estimated with high accuracy.
- the exhaust unit 4 can purposely remove it from the material stream M at the blow-off time tb on the basis of the highly precisely determined blow-out position of this object (if it is a bad object).
- the applied predictive multi-object tracking method additionally provides an uncertainty indication of the estimated variables in the form of a variance (blow-out time) or covariance matrix (blow-out position).
- FIGS. 3 and 4 show in more detail the procedure which can be used according to the invention for predictive multi-object tracking. In terms of time, this procedure can be subdivided into two phases, a tracking phase and a prediction phase (where the prediction phase takes place after the tracking phase in terms of time).
- FIG. 4 clarifies that the tracking phase is composed of filter and prediction steps and the prediction phase is limited to prediction steps.
- the first phase (tracking phase) is assigned to the field of view 3 'of the area camera 3. While a certain object from the set of objects Ol, 02, ...
- this region 3 can in the individual, t_ at the times 5, t_ 4, t_ 3, ... are identified recorded camera images and it can be done maintaining a spatial position determination.
- t_ at the times 5, t_ 4, t_ 3, ... are identified recorded camera images and it can be done maintaining a spatial position determination.
- the orientation of the object in the camera images so that not only the spatial position but also the orientation of the objects at several different points in time (ie the object pose) is determined in the first step of the invention in the second step according to the invention, the location at least one defined time (the blow-out time) after the acquisition of the last camera image can be calculated on the basis of the location positions for the individual objects determined at the different times.
- FIG. 4 schematically shows this procedure of predictive multi-object tracking.
- recursive estimation methods can be used.
- non-recursive estimation methods can also be used for the tracking.
- the recursive methods eg Kalman filter methods
- parameters of equations of motion can be estimated in the tracking phase, wherein the equations of motion can describe a movement model for the movement of a single object.
- the recorded, ie optically acquired, information ie the movement path of the individual recorded location positions or, if the position is detected, of the movement and orientation change path resulting from the ones recorded at the several different times reposen results
- the future movement path of the object under consideration are estimated with high accuracy and thus also its location to the later, potential (if it is a
- the subsequent prediction phase (during which the object in question, after the object
- This second phase of object tracking may consist of one or more prediction steps based on the motion models previously determined in the tracking phase (e.g., estimated rotational motions).
- the result of this prediction phase is an estimate of the location at a later point in time (such as, for example, the discharge time tb and the location at this time, ie the discharge position Xb (tb)). Tracing the objects thus takes place in two phases.
- the tracking phase consists of sequences of filtering and prediction steps. Filtering steps refer to processing camera images to improve current position estimates, and prediction steps continue to estimate the position until the next camera image, ie, next filter step.
- the prediction phase following the tracking phase consists only of prediction steps since no filter step can be performed due to missing camera data.
- the tracking phase can be performed in different ways: Either non-recursively, whereby the current object positions or object positions are determined from each image (no movement models have to be used.) All object positions acquired over time can be collected to form trajectories for the individual objects Recursive processing is also possible, so that only the current position estimation of an object has to be provided, using the motion models (prediction steps) to predict the movement of the object between camera measurements and thus correlating different filter steps the prediction of the results of the previous filtering step as prior knowledge In the case, a weighting occurs between the predicted positions and the positions determined from the current camera image. It is also possible to work recursively with an adaptation of the movement models: this involves a simultaneous estimation of object positions or positions and model parameters.
- acceleration values can be determined as model parameters.
- the movement models are thus identified during the tracking phase. It can be a fixed model for all objects or individual movement models.
- the reference numeral designates the extrapolation of the movement path 1 of an object determined in the tracking phase over the detection period of this object by the camera 3, ie the predicted trajectory of the object after leaving the detection range of the camera 3 ', thus in particular also at the time of the flyby on the blow-off - unit 4 (or through the detection area 4 'of the same).
- the prediction phase can directly use the model information previously determined in the tracking phase and consists of pure prediction steps since camera data are no longer available and therefore no filter steps can be performed any more.
- the prediction phase can be subdivided further, for example into a phase in which the objects are still on the conveyor belt and a flight phase after leaving the conveyor belt.
- two different movement models can be used in both phases (for example a two-dimensional movement model on the conveyor belt and a three-dimensional movement model in the subsequent flight phase).
- One way to render the camera image data for object tracking is to transform the data into a set of object locations by image preprocessing and segmentation techniques.
- image preprocessing methods and segmentation methods are, for example, inhomogeneous point operations for the removal of illumination inhomogeneities and area-oriented segmentation methods as described in the literature (B. Jähne, Digital Image Processing and Image Acquisition, 7th, revised edition 2012, Springer, 2012, or J. Beyerer, F ,
- Kalman filter methods or other methods for (non-linear) filtering and state estimation can be used, as described, for example, in F. Sawo, V. Klumpp, UD Hanebeck, "Simultaneous State and Parameter Estimation of Distributed Physical Systems based on Sliced Gaussian Mixture Filter ", Proceedings of the llth International Conference on Information Fusion (Fusion 2008), 2008.
- the determination of motion model parameters has two functions:
- these parameters are used in both the tracking and prediction phases to compute the prediction step (s) to allow accurate prediction of blowout timing and position (eg, the model predicted during the tracking phase Position of an object can be compared with the object position actually measured in this phase and the parameters of the model can be adjusted if necessary).
- model parameters extend the feature space, on the basis of which the classification and the subsequent activation of the blow-out unit can take place.
- bulk materials can be classified in addition to the visually recognizable features based on differences in the movement behavior and sorted accordingly.
- FIG. 5 instead of a single area camera 3, a plurality of individual line scan cameras arranged along the conveyor belt 2 and above it are used (line alignment perpendicular to the transport direction x and perpendicular direction z of the cameras 3a to 3c onto the plane of the conveyor belt xy, ie in the y direction).
- the z direction here corresponds to the direction of pickup of the camera 3 (FIG. 1) or of the plurality of cameras 3 a to 3 c (FIG. 5).
- FIG. 5 shows, it is thus also possible to use a plurality of line cameras (or also multiple area cameras with one or more regions-of-interest, ROIs) spatially distributed along the conveyor belt 2 with preferably constant intervals, including the illuminations 5 assigned to each of the cameras.
- the line scan cameras or the area cameras can be mounted both above the conveyor belt 2 and above the trajectory of the bulk material in front of a problem-adapted background 7 (this applies in the example shown for the last camera 3c seen in the transport direction x of the belt 2).
- the image acquisition achieved in this way is outlined in FIG. 6, in contrast to FIG. 5 (which shows only three line scan cameras 3 a to 3 c) here for a total of six different line scan cameras arranged one behind the other along the transport direction x (whose detection regions are designated 3 a 'to 3 f).
- the present invention has a number of significant advantages.
- the present invention even makes it possible in the first place to carry out optical sorting of the type described.
- the method for multi-object tracking enables improved optical characterization and feature extraction from the image data of the individual objects 0 of the observed bulk material flow M. Since the non-cooperative objects generally present themselves in different three-dimensional layers of the camera due to their additional proper motion, image features of different object views can become one cumulative object feature over the individual observation times. For example, the three-dimensional shape of an object can also be estimated and used as a feature for the sorting. The extrapolation of the three-dimensional shape of an object from the recorded
- Image data can be written as described in the literature (see, for example, SJD Prince “Computer vision models, learning, and inference", New York, Cambridge University Press, 2012) using, for example, the visual envelope of the individual objects in different poses. from silhouettes method).
- the extended object features can also be used for improved motion modeling in predictive tracking, for example, by using the three-dimensional shape for predicting flight dynamics. track is taken into account.
- the identified model that characterizes the motion path 1 of a particular object can itself be used as a feature for a classification or sorting decision.
- the movement path 1 determined on the basis of the individual camera shots as well as the future movement path estimated on the basis of the movement path 1 are influenced by the geometric properties and the weight of the object and accordingly offer a possibility of belonging to one bulk fraction.
- Another technical advantage for bulk material sorting is provided by the evaluation of the additional uncertainty descriptions for the estimated discharge time and the discharge position. This allows a customized control of the pneumatic blow-out unit for each
- the multiple position determination of objects of the bulk material flow at different times as well as the evaluation of a sequence of images instead of a snapshot image (this may also involve a multiple measurement, calculation and cumulation of object features at different times as well as a use of identified motion models as a feature for an object classification) generally achieved a significantly improved separation in the automatic sorting of any bulk materials.
- the mechanical outlay for material calming can be considerably reduced.
- the present invention can be used for the sorting of complex shaped bulk materials, which must be checked from several different views, using only a single area camera in a fixed position.
