Definitions
- the invention relates to a method for detecting an object by a mobile system, in particular in a technical system, wherein the mobile system has at least one first sensor and at least one second sensor.
- the technical system is in particular an industrial application, for example a production plant, an industrial hall or a logistics center.
- the mobile system is, for example, an autonomous vehicle.
- the mobile system is used, for example, to transport objects within the technical system. There are also other objects in the technical system.
- the mobile system has a sensor, in particular a laser scanner, for detecting such objects and distances to such objects.
- the mobile system has a first sensor, which is designed as a laser scanner, and a second sensor, which is designed as a monocular camera. By linking the data recorded by the two sensors, objects in the technical system are recognized.
- Objects can be detected from images recorded by a camera.
- Image pyramids are usually created and used for object detection.
- An image pyramid is associated with an object and has multiple scale levels. Each scale level includes an object image of a different size. Each scale level shows the object at a different distance. To find the object in an image, all scaling levels of the pyramid must be processed, each comparing it to the object image at the scaling level. The comparison with the large number of object images is computationally intensive.
- the invention is based on the object of developing a method for detecting an object using a mobile system.
- a method for detecting an object by a mobile system in particular in a technical system, is proposed.
- the mobile system has at least one first sensor, at least one second sensor and at least one image pyramid.
- the at least one image pyramid is assigned to an object and contains several scaling levels, each of which includes an object image.
- the first sensor several points of an object are detected, and distances to the detected points are determined, and a resulting distance to the detected points is determined.
- the second sensor an image containing the object is recorded, and an image of the object is recognized in the recorded image.
- At least one scaling level is selected from the at least one image pyramid, to which the resulting distance is assigned.
- the object image of the at least one selected scaling level is compared with the image recognized in the captured image. If the object image matches the image, the object in the image is detected.
- An object to which an image pyramid is assigned is, for example, a pallet, a forklift or a grid box.
- the first sensor is designed as a laser scanner.
- the resulting distance to the detected points is determined as the arithmetic mean of the determined distances to the detected points.
- the resulting distance therefore corresponds to a distance from the first sensor to a point in the middle of the object.
- the resulting distance to the detected points is determined as the smallest of the determined distances to the detected points.
- the resulting distance therefore corresponds to a distance between the first sensor and a side of the object facing the mobile system.
- the scaling levels of the at least one image pyramid are discrete and each include an object image at exactly one resulting distance. According to an advantageous development of the invention, a range of resulting distances is assigned to each scaling level of the at least one image pyramid. This means that resulting distances that lie between two discrete scaling levels can also be processed.
- the mobile system has a position sensor for detecting a position of the mobile system, particularly within the technical system.
- the sensor in question is, for example, a GPS receiver or a SLAM system. Recording the mobile system's own position, especially in the technical system, makes it possible to create a local map, which forms the basis for the autonomous driving of the mobile system.
- Figure 1 a schematic side view of a mobile system and an object in a technical system
- Figure 3 a picture with an image of the object
- Figure 5 an overlay of the image with the recorded points.
- Figure 1 shows a schematic side view of a mobile system 10 and an object 11 in a technical system.
- the object 11 in this case is a pallet.
- the technical system has additional objects 11 not shown here, for example additional pallets, forklifts and mesh boxes.
- the technical system also has other mobile systems 10, not shown here, which are designed in the same way.
- the mobile system 10 is designed as an autonomously driving vehicle and has a drive device, an electrical energy storage device for supplying the drive device and a control unit for controlling the drive device.
- the mobile system 10 also has a position sensor for detecting a position of the mobile system 10 within the technical system.
- the mobile system 10 also includes a communication device for wireless communication over a network.
- the mobile system 10 in the present case has two first sensors 1, which are designed as laser scanners. Each of the first sensors 1 is used to detect objects 11 and to detect distances to detected objects 11. The first sensor 1 detects several points P of the object 11 and determines the distances to the detected points P.
- the mobile system 10 has a second sensor 2, which is designed as a monocular camera. The second sensor 2 is used to record images on which objects 11 in particular are depicted.
- the mobile system 10 is located on a level floor in the technical facility.
- the first sensors 1, designed as laser scanners, are arranged on the mobile system 10 in such a way that the scanning planes of the first sensors 1 are aligned parallel to the floor.
- the second sensor 2, designed as a monocular camera, is arranged on the mobile system 10 in such a way that the optical axis of the second sensor 2 is aligned parallel to the ground.
- FIG 2 shows a schematic top view of the mobile system 10 and the object 11 in the technical system shown in Figure 1.
- the mobile system 10 has an approximately rectangular cross section.
- the first sensors 1, designed as laser scanners, are arranged at opposite corners of the mobile system 10.
- the second sensor 2, designed as a monocular camera, is arranged on a front side of the mobile system 10.
- the geometric arrangement of the first sensors 1 relative to the second sensor 2 on the mobile system 10 can be detected by calibration and is therefore known.
- the geometric arrangement in question is constant and is therefore not changed dynamically.
- a transformation of detected points P and distances to the detected points P into a recorded image can clearly be carried out.
- the mobile system 10 also has several image pyramids. Each image pyramid is assigned to an object. Such objects are, for example, a pallet, a forklift or a wire mesh box. Each image pyramid contains multiple scaling levels. Each scaling level includes an object image. The object images of the scaling levels have different sizes. Each scaling level therefore shows the object at a different distance.
- FIG. 4 shows the detected points P of the object 11 shown in FIG. 1. From the distances of the mobile system 10 to the detected points P, a resulting distance of the mobile system 10 to the detected points P is determined.
- a hypothetical object is proposed from the detected points P of the object 11 and the distances of the mobile system 10 to the detected points P. Based on the position and orientation of the points P, a pallet is proposed as a hypothetical object.
