Patent number: 9122266Abstract: In a method for collision-free interaction between a machine having mobile machine elements and objects in its vicinity, safety regions are established and monitored using the knowledge of the current position and the dynamic behavior. In particular, image data of the mobile machine element are recorded by means of an image acquisition system and are correlated with a database compiled in a training phase with image data of at least one mobile machine element. The database contains image data relating to a plurality of movement phases within the movement process of the machine. Using the database, both the current position of the mobile machine element is ascertained and a future position, reachable within the stopping time, is estimated. The dynamic behavior of the machine in the event of collision risk is optimized on the basis of this estimation.Type: GrantFiled: January 30, 2009Date of Patent: September 1, 2015Assignee: PILZ GMBH & CO.

Patent number: 8379969Abstract: The invention relates to a method for matching an object model to a three-dimensional point cloud, wherein the point cloud is generated from two images by means of a stereo method and a clustering method is applied to the point cloud in order to identify points belonging to respectively one cluster, wherein model matching is subsequently carried out, with at least one object model being superposed on at least one cluster and an optimum position of the object model with respect to the cluster being determined, and wherein a correction of false assignments of points is carried out by means of the matched object model. A classifier, trained by means of at least one exemplary object, is used to generate an attention map from at least one of the images. A number and/or a location probability of at least one object, which is similar to the exemplary object, is determined in the image using the attention map, and the attention map is taken into account in the clustering method and/or in the model matching.Type: GrantFiled: April 8, 2010Date of Patent: February 19, 2013Assignee: Pilz GmbH & Co.

Patent number: 8154590Abstract: A method for observing a person in an industrial environment using a multicamera system to acquire image data about the position and alignment of a person, including a person's body parts. These image data are then examined with regard to the imaging of a person so that whenever a person has been detected in the image data, an articulated virtual 3D model of the human body is matched to this person hypothesis. Subsequently, this virtual body model is continuously matched to the movement behavior of the person detected in the image data. A hazard potential is determined using knowledge of the position and the movement behavior of the virtual body model in space. The hazard potential thus determined is subjected to a threshold value comparison in order to act upon the movement control of the machine or the machine part in the event of this threshold value being exceeded.Type: GrantFiled: January 30, 2009Date of Patent: April 10, 2012Assignee: Pilz GmbH & Co.

Patent number: 8135211Abstract: Passive methods for three-dimensional reconstruction of a scene by means of image data are generally based on the determination of spatial correspondences between a number of images of the scene recorded from various directions and distances. A method and a device are disclosed which provide a high reliability in the solution of the correspondence problem in conjunction with a low computational outlay. Image areas for determining the correspondences are determined within a plurality of images forming at least two image sequences. In preferred embodiments, a parameterized function h(u, v, t) is matched to each of the image areas in a space R(uvgt) defined by pixel position (u, v), image value g and time t. The parameters of the parameterized functions are used to form a similarity measure between the image areas.Type: GrantFiled: September 19, 2008Date of Patent: March 13, 2012Assignee: Pilz GmbH & Co.

Publication number: 20090237499Abstract: Manufacturing processes profit greatly from a close collaboration between human and machine. Whereas a human behaves flexibly and adaptively but is inclined to make mistakes during repetitive work operations, machines operate quickly and exactly but are static and not very flexible. In order to enable an improved hazard protection in the context of a safe human-machine interaction, a spatial- and time-dependent variable degree of hazard is allocated to monitored spatial areas as a function of the current position and the current movement state of a machine or a machine element, as well as of the observed person. For this purpose, a multicamera system is used to acquire image data of the person in order to obtain the most detailed information possible about the position and alignment of a person, in particular also with reference to the body parts thereof, in an industrial environment.Type: ApplicationFiled: January 30, 2009Publication date: September 24, 2009Inventors: Ulrich Kressel, Lars Krueger, Werner Progscha, Christian Woehler, Franz Kummert, Joachim Schmidt, Rainer Ott

Publication number: 20090222134Abstract: In modern industrial robots which move at considerable speeds, collisions generally cause serious damage to the robots and the collision objects. This can lead to injuries and expensive production stoppages. In a method for collision-free interaction between a machine having mobile machine elements and objects in its vicinity, safety regions are established and monitored using the knowledge of the current position and the dynamic behavior. In particular, image data of the mobile machine element are recorded by means of an image acquisition system and are correlated with a database, which has been compiled in a training phase with image data of at least one mobile machine element. The database contains image data relating to a plurality of movement phases within the movement process of the machine.Type: ApplicationFiled: January 30, 2009Publication date: September 3, 2009Inventors: Andre Franke, Lars Krueger, Christian Woehler
