Definitions
- the invention relates to a computer-implemented method for environment recognition for an automated driving system, a machine learning method, a control unit for an automated driving system and a computer program for such a control unit.
- Automated driving systems such as autonomous vehicles, require a number of sensors to recognize their surroundings and to find their way around in their environment.
- An important sensor for a self-driving vehicle is the camera. It is used, for example, to recognize lanes, vehicles and obstacles and incorporate them into the control of the autonomous vehicle.
- Each image captured by the camera is processed with a neural network and analyzed using a method developed by the programmer. This method can, for example, recognize other road users, display the course of the road or recognize lane markings.
- Each recognition process has a different output here, that is, it perceives the elements of the environment visible in the image with different processes and different goals.
- the different algorithms used for the different detections of the different types/classes of road traffic objects process the data from sensors such as cameras or other sensors such as lidar, radar, acoustic sensors, ultrasonic sensors, olfactory sensors all at the same time and in the Rule with the same frame rate. It is imperative that they run parallel to one another, since, for example, lane markings and other road users must be recognized at the same time, but cannot be represented in the same way.
- ADAS advanced driver assistance systems
- AD autonomous driving
- CNN convolutional neural network
- a CNN takes on the task of recognizing the different object classes.
- the image is used as a matrix with color values and filters with values - learned by the neural network - process the image into a transformed image. This transformation is repeated many times in current neural networks together with other image processing steps, so that a CNN with up to hundreds of layers can be created.
- these take on the form of the output, for example the coordinates of a rectangular box if road users are detected.
- CNNs Layers of CNN.
- the layers appear in all CNNs and are similar technically strong. This applies to both camera-based image recognition and those based on other sensors.
- CNNs consist of two parts, the so-called backbone, which is an arrangement of layers on top of the image/sensor input, and the head, called head, which processes the last layer of the backbone into the desired output.
- the backbone contains most of the layers of the network and accordingly takes the most time to calculate the values mathematically.
- CNNs are required for complex systems in the field of ADAS or AD, with each individual network already making very high calculation demands.
- Running the CNNs in parallel incurs high costs, both for powerful hardware and for power consumption. For this reason, the reduction of computing capacity is highly relevant for a mature system.
- Backbone head architectures are known, for example, from https://arxiv.org/pdf/1703.06870.pdf.
- a backbone with two closely related types of detection namely box and mask for an object, is disclosed.
- the segmentation is a binary instance segmentation.
- the object of the invention was to provide a holistic detection system for the AD/ADAS area, which merges the tasks of multiple networks and can use a single backbone to be able to predict a large number of target detection types.
- the objects of claims 1, 7, 9 and 10 each solve this problem with a single backbone. This eliminates the majority of arithmetic operations and thus latency times.
- One aspect of the invention relates to a computer-implemented method for environment recognition for an automated driving system.
- the procedure includes the steps
- the network architecture includes a first artificial neural network for determining first features from data from at least one sensor for detecting the surroundings of an automated driving system. Furthermore, the network architecture includes second artificial neural networks for classification, localization and/or prediction for different detection types of automated driving based on the first features.
- the procedure includes the steps
- a further aspect of the invention relates to a control unit for an automated driving system.
- the control unit includes at least one first interface, via which the control unit receives data from at least one sensor for detecting the surroundings of the driving system.
- the control unit includes a processing unit.
- the processing unit is designed to implement a network architecture comprising a first artificial neural network for determining first features from the data and second artificial neural networks for classification, localization and/or prediction for different types of recognition of automated driving based on the first features and an environment recognition and To determine control and / or control signals according to a method according to the invention.
- the control unit includes second interfaces via which the control unit provides the control and/or control signals to actuators for longitudinal and/or lateral guidance of the driving system.
- a further aspect of the invention relates to a computer program for a control unit according to the invention.
- the computer program includes instructions that cause the control unit to execute a method according to the invention and/or a machine learning method according to the invention when the computer program runs on the control unit.
- Computer-implemented means that the steps of the method are executed by a data processing device, for example a computer, a computing system, a computer network, for example a cloud system, hardware of a control device, or parts thereof.
- Automated driving systems include automated vehicles, road vehicles, people movers, robots and drones.
- Sensors for detecting the surroundings include optical sensors such as cameras, including infrared cameras, and lidar, radar sensors, acoustic sensors such as microphones, ultrasonic sensors and olfactory sensors such as electronic noses.
- the sensors can be arranged, for example, on an outer skin and/or inner skin of the automated driving system.
- the data from the sensors includes raw data and pre-processed data, for example filtered raw data with an improved signal-to-noise ratio.
- the first artificial neural network has the function of a backbone network.
- the first artificial neural network is a backbone network that predicts a large number of target recognition types, in particular target recognition types that are not closely related to one another.
- the first artificial neural network is called the multi-detection backbone, abbreviated MEB.
- the backbone network includes layers of a convolutional network.
- a DLA-34 network see https://arxiv.org/pdf/1707.06484.pdf
- ResNet see https://arxiv.org/pdf/1512.03385.pdf
- Inception see https ://arxiv.org/pdf/1409.4842.pdf or MobileNets, see https://arxiv.org/pdf/1704.04861.pdf.
- the first layers of the backbone network extract general characteristics from the data, for example from image data, which are used for a large number of other tasks.
- the first features include general features that are used as input for the different types of recognition.
- the second artificial neural networks have the function of detection heads, i.e. they correspond to the heads in a backbone head architecture.
- the invention proposes the use of multiple detection heads, for example four detection heads. Each detection head represents an output of the backbone.
- the detection heads share the backbone network. For example, in a pre-trained backbone network, the last Replaced layers of the backbone network with the detection heads.
- Each recognition head is post-trained for a specific target task, for example a specific recognition type. According to the invention, a number of detection heads are used with a single backbone, with the detection heads being trained/post-trained together.
- the second artificial neural networks include layers of a convolutional network, recurrent layers, or fully connected layers, for example.
- This proposed architecture has several advantages over the classical multiple mesh approach.
- a system with several outputs that are related in terms of content is more robust and precise.
- the inclusion of all sensors and representations of the different but related task types in the automotive context also leads to a safer overall system.
- the proposed system does not only represent an in-depth object detection, but can cover several or all necessary detection types of autonomous driving and can be individually adapted to this problem. These types of detection are used in the higher control levels of such an autonomous system, including planning, trajectory prediction, simultaneous localization and mapping, and combine to form the final actuator control.
- the MEB anticipates mutually unfamiliar and generally all detection types, such as weather from raindrops in the roadscape and lane markings on asphalt.
- the data in particular the images from a camera that the first artificial neural network receives to determine the first characteristics, show the traffic on the road. Therefore, knowledge about objects and the different types of recognition in the first artificial neural network can only be learned together in order to to obtain universally valid characteristics for all detection types. Otherwise, the first artificial neural network would already make a distinction based on the different nature of the image domain. However, a backbone network with several heads would not learn with this. It is problematic that an identified or labeled data set in the form of image-line pairs for training the network architecture according to the invention does not generally exist.
- a data set for training a weather forecast comprises a large number of image-target pairs in the form (image_0, target_0_weather), (image_1, target_1_weather), (image_2, target_2_weather), etc.
- the MEB should simultaneously recognize weather and lane markings, for example .
- a data set in the form (Image_0, Target_0_weather, Target_O_lane marker), (Image_1, Target_1_weather, Target_1_lane marker), (Image_2, Target_2_weather, Target_2_lane marker), etc. would be required for a corresponding training. With more than two types of recognition, such a data set would become even more extensive. The entire data set would also have to be adjusted manually for the addition of a sensor or a type of detection.
- the network architecture according to the invention is trained directly with the correct labels. It is then not necessary to generate pseudo labels.
- the machine learning method according to the invention enables the MEB to be trained with multiple heads.
- Machine learning is a technology that teaches computers and other data processing devices to perform tasks by learning from data, rather than being programmed to do the tasks.
- Gradient-based has the usual meaning that training data pairs comprising tagged data are fed forward through an artificial neural network and in a back-feed a cost function of the network is minimized by gradient formation of the network's weights.
- third artificial neural networks are used, which are trained for individual special tasks, for example the different types of recognition.
- the third artificial neural networks called specialist networks. Publicly accessible data sets, with which the specialist networks are trained, are available for such special tasks.
- the specific labels generated by the third artificial neural networks are so-called pseudo labels.
- the pseudo labels are predictions of the third artificial neural networks on a data set.
- the first artificial neural network is trained with these pseudo labels. This corresponds to a so-called transer learning or distillation of a network.
- the prediction with the highest probability is used as the pseudo label.
- the entire probability distribution from the prediction of the teaching network, i.e. the third artificial neural networks is given to the learning network, i.e. the first artificial neural network with the second artificial neural networks, which improves the training.
- each data example also called data sample
- the third artificial neural networks generate all recognition targets in the same data example, for example in the same image. This enables training of the first artificial neural network with multiple recognition heads.
- the invention thus makes it possible to generate pseudo labels for any number of sensor data without a label.
- the third artificial neural networks include layers of a convolutional network, recurrent layers, or fully connected layers, for example.
- the computer program instructions include software and/or hardware instructions.
- the computer program is loaded into a memory of the control device according to the invention, for example, or is already loaded into this memory. According to a further aspect of the invention, the computer program according to the invention is executed on hardware and/or software of a cloud facility.
- the computer program is loaded into the memory, for example, by a computer-readable data carrier or a data carrier signal.
- the invention is thus also implemented as an aftermarket solution.
- the control unit prepares input signals, processes them using an electronic circuit and provides logic and/or power levels as regulation and/or control signals.
- the control device according to the invention is scalable for assisted driving through to fully automated/autonomous/driverless driving.
- the processing unit includes, for example, a programmable electronic circuit.
- the processing unit or the control device is designed as a system-on-chip.
- the invention relates to a computer system with input and output, a processing unit and storage devices.
- the computer system is designed to implement the network architecture according to the invention.
- the invention thus provides a use of the network architecture according to the invention in areas outside of automated driving.
- the proposed network architecture is adaptable to specific hardware by considering, for example, main memory of the ECU, CPU and GPU cores, cache memory, and clock for the architecture choice.
- the built-in hardware can be used better as a result of the split backbone network according to the invention.
- the first artificial neural network determines the first features for the object detection, semantic segmentation, traffic sign detection and lane marking detection types of detection.
- a first of the second artificial neural networks recognizes objects.
- a second of the second artificial neural Networks breaks down areas of data into semantically related units.
- a third of the second artificial neural networks recognizes traffic signs.
- a fourth of the second artificial neural networks recognizes lane markings.
- the first of the second artificial neural networks is a recognition head for object detection.
- Object detection includes
- Annotation estimation for the detected objects such as, for example, the state of pedestrians in the case of pedestrians, for example running, stationary, or the state of the vehicle in the case of vehicles, for example parking, stopped, blinking.
- the second of the second artificial neural networks is a semantic segmentation recognizer.
- the semantic segmentation includes
- the third of the second artificial neural networks is a traffic sign recognition head. This detection includes
- the fourth of the second artificial neural networks is a lane marking recognition head. This recognition includes fitting, extrapolating from appropriate models such as clothoids, polynomials, splines, and the like. According to one aspect of the invention, more of the second artificial neural networks are used for the following tasks:
- a holistic segmentation in particular no binary segmentation, for example into pedestrians and non-pedestrians.
- the segmentation is done on the whole image for all classes.
- each of the second artificial neural networks when each of the second artificial neural networks is executed, a respectively predetermined number of layers of the first artificial neural network is accessed. This makes it possible for each of the second artificial neural networks to be transformed with a configured number of layers of the backbone before the individual last processing steps necessary for the corresponding type of recognition are carried out, for example non-maximum suppression or softmax. This achieves an individually adjustable depth of cleavage.
- data from a number of sensors for recognizing the surroundings of the driving system are entered and merged into the first artificial neural network in order to obtain the first features.
- the multiple sensors are sensors of one sensor technology or, according to a further aspect, sensors of different sensor technologies. This feeds various sensor data into the MEB, expanding it into a multi-fusion backbone, or MFB for short. Sensors such as cameras, lidar and radar as well as other possible sensors such as acoustic or olfactory sensors can be included for the input. This results in the following fields of application, for example:
- the data is pre-processed in each case before input.
- each sensor's input is transformed with an individual number of layers of a convolutional network before entering the shared MFB backbone.
- the layer depth is made possible in addition to an architecture selection based on empirical findings using Neural Architecture Search, abbreviated NAS.
- NAS Neural Architecture Search
- the structure of an artificial neural network is used not chosen by the programmer, but the number and types of layers are also learned along with the parameters of the mesh.
- the number of slices is determined based on the data from the camera, radar, lidar and other sensors. This achieves a sensor-individually adjustable fusion depth.

- the third of the third artificial neural networks As an output from the third of the third artificial neural networks, two-dimensional boundary areas around the recognized traffic signs are obtained as identifiers for the traffic signs. Furthermore, the data example is input to a fourth of the third artificial neural networks. The fourth of the third artificial neural networks is trained to recognize lane markings. As an output of the fourth of the third artificial neural networks, coordinates of the lane markers are obtained as identifiers for the lane markers. Pseudo-labels of different recognition types including object detection, semantic segmentation, traffic sign recognition and lane marking recognition are generated on a data sample and thus a completely complex labeled data set for training the MEB or MFB.
- the computer program comprises first software code sections, which are used to program a first artificial neural network for determining first characteristics from data from at least one sensor for detecting the surroundings of an automated driving system. Furthermore, the computer program includes second software code sections, which are used to program second artificial neural networks for classification, localization and/or prediction for different detection types of automated driving based on the first features.

It takes advantage of the layered structure of various current convolutional network backbones, such as concatenating layers from ResNet, using Batchnorm, etc. While DLA-34 is a very efficient convolutional network, it is used here as an example only can also be substituted with a less performant convolutional network.

It can also be seen in FIG. 10 that the network carries out semantic segmentation, ie the pixel labeling of the people for the person class (general and not box-specific). The performance of the object detection is slightly better with 36.7% mAP in multitask training compared to 36.3% mAP for pure object detection in this setup. mAP means mean average precision. The additional output of the semantic segmentation takes up only 25% of the runtime of the network in the empirical test, compared to 100% with a comparable additional segmentation network.
