Definitions
- the application relates to a method for environmental detection using a lidar system, a lidar system for environmental detection and a vehicle with a lidar system.
- Modern vehicles have a large number of sensors whose data is used to provide driver information and/or driver assistance systems.
- the sensors record the vehicle's surroundings and other road users. Based on the recorded data, a model of the vehicle's environment can be created and changes in this vehicle environment can be responded to.
- a Lidar system has an optical transmitter unit and an optical receiver unit.
- the transmitter unit can emit an optical signal, which can be pulsed.
- light in particular laser beams in the ultraviolet, visual or infrared range, can be used as an optical signal.
- the optical signal can be received by the receiver unit after reflection from an object in a detection area in the vicinity of the Lidar system.
- the received optical signal can be evaluated using the transmitted optical signal by a control unit of the Lidar system using a time-of-flight method and the spatial position and distance of the objects on which the reflection occurred can be determined.
- reflection or reflected optical signal is any This is understood as a reflected optical signal (light) and should in particular also include light reflected by scattering or absorption emission. So-called time-of-flight (TOF) systems can be used in particular to determine the distance to objects.
- TOF time-of-flight
- Lidar systems are constantly being developed for various functions, e.g. for the acquisition of environmental information in the near and far range of vehicles, such as passenger cars or commercial vehicles.
- Lidar systems can also serve as sensor systems for driver assistance systems, in particular assistance systems for autonomous or semi-autonomous vehicle control. They can be used in particular to detect obstacles and/or other road users in the front, rear or blind spot area of a vehicle.
- Scanning lidar systems emit light beams that move in a scanning direction.
- Point scanners illuminate areas of the surrounding area point by point.
- Line scanners illuminate areas of the surrounding area line by line.
- DE102016122194A1 describes a method for operating a lidar system in which light pulses are emitted with a transmitting unit to detect an object and the light pulses reflected by the object are received with a receiving unit, wherein a light source of the transmitting unit is controlled at specific transmission times to emit the light pulses and the light pulses are deflected with a deflection device within a predetermined detection range.
- the light source is controlled in such a way that time intervals between the specific transmission times differ from one another.
- a lidar system has a deflection device by means of which an optical signal can be deflected to scan a detection area.
- a method for environmental detection using the lidar system includes:
- a so-called frame of the lidar system is recorded.
- the optical signal hits an angle range of the detection area that depends on the angle.
- the angle can therefore also be referred to as the deflection angle.
- the detection area can be scanned step by step. Scanning lidar systems are also referred to as scanning lidar systems.
- At least one angle at which the optical signal is deflected into the detection area is different during the second scan from the angles during the first scan. This offers the advantage that, on the one hand, all angular ranges of the detection area are illuminated by the optical signal during the first and/or second scan and, on the other hand, time can be saved by omitting at least one angular range during the first scan. This means that at least one gap is left in the detection area during the first scan, which is then filled during the second scan by deflecting the optical signal into this gap.
- the first sampling period can therefore be shorter than a sampling period in which all possible angular ranges of the detection area would be scanned.
- the missing angular ranges can then be scanned in the second sampling period in order to be able to determine, for example, a high-resolution image of the detection area using a combination of first scanning and second scanning.
- Possible angular ranges are understood here to mean those angular ranges that depend on the angles that can be set by the deflection device. Possible angular ranges therefore refer to those angular ranges that are scanned by the optical signal when it is deflected at the angles that can be set by the deflection device.
- the deflection device can have, for example, at least one single-sided or multi-sided, rotating or oscillating optical element, e.g. at least one mirror, to effect the deflection.
- the deflection can be based on reflective light deflection, e.g. by at least one mirror, and/or transmissive light deflection, e.g. by at least one prism and/or an optical array.
- the detection range of the lidar system includes the area into which the optical signal is emitted by a transmitting unit of the lidar system.
- the lidar system has a deflection device, which can, for example, comprise at least one mirror.
- the at least one mirror can, for example, perform a rotary movement, which can comprise a pendulum movement and/or a rotational movement.
- the scanning direction depends on the rotary movement of the at least one mirror.
- the step-by-step change in the angle of deflection of the optical signal can be achieved, for example, by controlling the deflection device.
- the deflection device can be controlled, for example, by a control unit of the lidar system. By controlling the deflection device, the step size of the angle change and thus the angular resolution within the detection range can be adjusted.
- the control unit of the lidar system can also be designed to control the transmitting unit and the receiving unit and to evaluate the transmitted optical signal and the received optical signal for environmental detection.
- the receiving unit has a receiving sensor by means of which the reflected optical signal can be received.
- the receiving sensor can also be designed two-dimensionally and have individual pixels that are arranged in a field.
- the respective pixels can be assigned to respective directions, i.e. angular ranges, from which they can receive optical signals.
- the pixels can be designed in such a way that they can be specifically activated for reception.
- the signal during the first sampling period and the signal during the second sampling period is The reflected optical signal is evaluated and a measured value image is determined depending on the evaluation.
- the measurement image contains measurement values that were determined by evaluating the optical signal during the first sampling period and the second sampling period. It includes the measurement values of both frames of the Lidar system.
- the repetition rate of the respective sampling periods is also referred to as the refresh rate or frame rate.
- a shorter sampling period can be repeated more quickly and thus enables a higher refresh rate.
- With a higher refresh rate changes in the environment to be recorded can be detected more quickly, e.g. when an object moves into the detection area.
- the measured value image can include information about objects in the detection area on which the optical signal was reflected.
- the measured value image also includes information about the angle at which the optical signal was deflected, which was evaluated at the respective pixel.
- the resolution of the image therefore depends on the angular resolution of the lidar system.
- a measurement image can, for example, contain an image with depth information.
- the depth information can correspond to distance information, such as that which can be determined using a time-of-flight measurement method. Examples of time-of-flight measurement methods are indirect or direct time-of-flight methods.
- Such a measurement image has the advantage that it can be determined with full resolution, since information from the first and second scans can be combined.
- the gaps in the individual frames can be filled and a complete, high-resolution measurement image can be created.
- the optical signal is emitted in pulses and the angle is changed step by step from pulse to pulse.
- light pulses are emitted by the transmitting unit.
- the light pulses reflected from the detection area are received by the receiving unit.
- a light source e.g. a laser diode
- the transmitting unit is controlled at specific transmission times and the light pulses are deflected with the deflection device at the respective angle.
- the light source is controlled in particular such that the time intervals between the specific transmission times within a sampling period are the same.
- the time intervals between the specific transmission times within the first sampling period can also be the same as within the second sampling period.
- the respective transmission times can be triggered when the respective angles of the light deflection are reached.
- this can be done by angle sensors on the deflection device, which have a much higher resolution compared to the angle ranges.
- the detection area is scanned from a first edge area to a second edge area by gradually changing the angle within the first scanning period and/or within the second scanning period.
- This embodiment has the advantage that the entire detection area can be detected during the first scanning period and/or during the second scanning period.
- the individual frames that can be recorded one after the other each cover the detection area in its width from edge area to edge area.
- This also allows the edge areas of the detection area to be scanned twice as often.
- the scanning that takes place can have gaps because not all angular areas of the detection area may have been scanned during the first and/or second scanning period, but the resolution can be selected so that larger objects or larger changes, particularly in the edge areas, are detected during one scanning period. These changes can then be responded to.
- any gaps in the first scan can then be filled by the second scan, which then covers angular areas that were omitted during the first scan.
- one possible angle is omitted during the step-by-step change of the angle, and the optical signal is deflected within the second sampling period with the respective omitted possible angles.
- sampling during the first sampling period takes place in such a way that the optical signal is deflected with only every second possible angle, so that one possible angle range is alternately scanned and the following one is not, etc.
- the optical signal is deflected with the other angles, so that during the second sampling period those angle ranges are scanned that were omitted during the first sampling period.
- the second sampling is therefore carried out with an offset compared to the first sampling.
- the first sampling is carried out alternately with the second sampling.
- the acquisition of the individual frames through the sampling periods can be repeated continuously. If the first sampling and the second sampling are carried out alternately, the measurement image can be determined after each frame, which depends on information from the current sampling and the previous sampling and which can therefore have the full resolution. It is therefore possible to continuously determine the measurement image from the two previous measurement images. In particular, the measurement image can also be determined from more than two previous measurement images.
- the step size of the angle change within the first sampling period is the same as within the second sampling period.
- This can relate to the actual angle change during the first and second sampling periods, i.e. the angle change with the gaps with respect to the possible angle changes.
- the step size of the actual angle change during the first sampling period is the same as during the second sampling period.
- the possible angle changes within the first and second sampling periods can be the same. This has the advantage that a deflection device can be used. which provides the same possible deflection angles during the first sampling period.
- the step size of the angle change between possible angles corresponds to the angular resolution of the lidar system.
- the offset of the second scan compared to the first scan therefore corresponds to the angular resolution of a lidar system.
- the angular resolution of the lidar system is used to detect the environment, so that, for example, the measured value image can then be determined in the possible angular resolution of the lidar system.
- the lidar system for environmental detection has a deflection device which is designed to deflect the optical signal for scanning the detection area, wherein the lidar system is designed to carry out the described first scanning within the first scanning period and the described second scanning within the second scanning period.
- the angle at which the optical signal is deflected into the detection area by the deflection device is changed step by step and the optical signal reflected from the detection area is evaluated.
- the angle at which the optical signal is deflected into the detection area by the deflection device is changed step by step and the optical signal reflected from the detection area is evaluated.
- At least one angle during the second scan is different from the angles during the first scan. This means that scanning gaps left in the detection area during the first scan, i.e. the gaps in the scan, can be filled by the second scan.
- the control unit of the lidar system is designed to evaluate the optical signal reflected from the detection area and to determine the measured value image. In this case, optical signals received from two sampling periods each can be evaluated for each measured value image. Preferably, the optical signal from the current sampling period and the previous sampling period is evaluated. It is also possible to evaluate the optical signals from more than two sampling periods.
- the lidar system is designed to output the measured value image.
- the measured value image By outputting the measured value image after each frame, it is possible to react quickly to changes in the detection area, since the measured value image can be output after the end of each sampling period.
- the measured value image can have a high resolution, since gaps in the scanning in one frame can be filled in by the other frame that was included in the measured value image.
- a vehicle can have such a lidar system.
- the vehicle can also have at least one control unit, wherein the at least one control unit carries out at least one driving function that depends on the measured value image.
- the control unit can have a computing unit, memory and input and output interfaces.
- the lidar system can be used, for example, on a vehicle in traffic to detect the environment in various situations. This makes it more versatile. It is possible to use the lidar system for situations where high resolution is required, e.g. to be able to detect small objects at a great distance. At the same time, the lidar system can also be used in situations where a high frame rate is required, e.g. to be able to react quickly to large objects moving at the edge of the detection area.
- a high resolution can be achieved by means of fine angular steps, which are achieved by the second scan filling gaps in the scanning pattern of the first scan.
- the first scan can be completed quickly because gaps can be left in the scanning pattern. This allows a high frame rate to be achieved by the first scan with gaps.
- the method and the lidar system therefore make it possible to multiply the frame rate by introducing the first, second and optionally further sampling periods, and at the same time to obtain a high-resolution, optionally even complete, measured value image, e.g. range image or distance image.

- Fig. 2 schematically shows a deflection device with detection range
- Fig. 3 schematic angular ranges in scanning direction
- Fig. 5 is a top view of a vehicle with Lidar system.
- Figure 1 schematically shows a method for environmental detection using a lidar system 30 with a first sampling period A and a second sampling period B.
- the two sampling periods A, B are carried out alternately.
- the first sampling takes place with the transmission of an optical signal L by a transmission unit 32 of the lidar system 30.
- the transmitted optical signal L is deflected in its direction by a deflection device 10.
- the angle 20 at which the optical signal L is a detection area 12 of the lidar system 30 is changed step by step.
- the optical signal L reflected from the detection area 12 is received by a receiving unit 34 of the lidar system 30.
- the second sampling takes place with the transmission of the optical signal L by the transmission unit 32 of the lidar system 30.
- the transmitted optical signal L is deflected in its direction by the deflection device 10.
- the angle 20 at which the optical signal L is deflected by the deflection device 10 into the detection area 12 of the lidar system 30 is changed step by step.
- the optical signal L reflected from the detection area 12 is received by the reception unit 34 of the lidar system 30.
- the deflection device 10 can have, for example, at least one single-sided or multi-sided, rotating or oscillating optical element, e.g. at least one mirror 14, to effect the deflection.
- At least one deflection angle 20 during the second scan fills one of the gaps left by the first scan.
- the deflection angles 20 during the second scan fill the gaps left by the first scan.
- the detection area 12 is scanned during the second scan with an offset compared to the first scan.
- Figure 2 shows schematically the deflection device 10 with the detection area 12.
- the deflection device 10 has a mirror 14 on which the optical signal L can be deflected at an angle 20.
- the mirror 14 is rotatably mounted and can perform a rotational movement with the direction of rotation 22 in the embodiment shown.
- the rotational movement of the mirror 14 can change the deflection angle 20 in a scanning direction 18.
- the mirror 14 can be controlled, for example, by a control unit 36 of the lidar system 30.
- the lidar system 30, to which the deflection device 20 shown in Figure 2 belongs, can, for example, belong to a scanning lidar.
- the optical signal L can be point-shaped, for example, and the mirror 14 can cause a 1D mirror deflection.
- the 1D mirror deflection scans the detection area 12 linearly, i.e. the step-by-step change in the deflection angle 20 of the optical signal L in the scanning direction 18 results in a line.
- a surface scan can then be achieved by lining up the lines.
- the optical signal L can also be line-shaped, for example, and the mirror 14 can cause a 2D mirror deflection.
- the 2D mirror deflection scans the detection area 12 linearly, i.e. the step-by-step change in the deflection angle 20 of the optical signal L in the scanning direction 18 results in a surface.
- the angular ranges 16 designated with A are scanned. Gaps, also called defects, are left. The defects are filled, i.e. scanned, within the second sampling period B. During both the first scanning and the second scanning, the respective angular ranges 16 are specifically illuminated with the optical signal L by adjusting the angle 20.
- the detection area 12 is scanned both during the first scan and during the second scan from an area near a first edge RI of the detection area 12 in the scanning direction 18 to an area near a second edge R2 of the detection area 12.
- This allows the areas around the edges RI, R2 to be detected both within the first scanning period A and within the second scanning period B. Detection in the area of the edges RI, R2 therefore occurs twice as often as when the entire detection area 12 is scanned without defects with the same angular resolution.
- a measured value image of the surroundings of the lidar system 30 can be determined.
- the optical signals L received during the first sampling period A and during the second sampling period B can be evaluated.
- the angle ranges 16 scanned by the optical signal L during the respective scanning periods A, B are plotted against the scanning direction 18. The nested individual frames of the first and second scanning are then shown at the bottom of Figure 3.
- Such nesting is possible continuously, i.e. information obtained during two or more previous scans can be combined. This makes it possible to implement a continuous combination of frames, so that a frame can be combined with at least one previous frame.
- Figure 4 shows a schematic of an embodiment of a temporal sequence of the individual trigger signals for emitting pulses of the optical signal L during the first sampling period A and the second sampling period B.
- the time intervals 24 between the trigger signals are always the same.
- the time 24 between two pulses of the optical signal L is therefore the same in the first sampling period A as in the second sampling period B.
- the time 26 between two pulses of the optical signal L when changing from the first sampling period A to the second sampling period B can be selected such that it is an integer multiple of the time 24 between two pulses and is shifted by half a time interval 24.
- the detection area 12 is then scanned in equal angular ranges 16 and the gaps in the first scan can be filled by the second scan.
- the integer multiple of the time interval 24 can be selected for the time 26 between the sampling periods so that any dead points of the light deflection are included. With the rotating mirror 14, this can, for example, affect the times in which a non-reflective area of the mirror 14 is facing a light source of the transmitting unit 32 of the lidar system 30. During such times, the emission of the optical signal L can then be suppressed and only start again - e.g. with the next sampling period - when a reflective surface of the mirror 14 is facing the light source again.
- the offset of the sampled angle ranges 16 of the sampling periods A, B. can correspond, for example, to the angular resolution of the lidar system 30. This allows the respective scanned angular ranges 16 correspond to the possible angles 20 of deflection by the deflection device 10.
- the angular resolution of the lidar system 30 can, for example, be in the range of hundredths of a degree. For the detection of large objects, the offset, i.e. the gaps in the scanning, can therefore be neglected. It is also possible to select a scan pattern that is not completely regular, in which, for example, the outer areas near the edges RI, R2 completely overlap. This would mean that certain angular areas near the edges RI, R2 are scanned both during the first scanning period A and during the second scanning period B.
- sampling periods A, B each of which leaves gaps in the sampling pattern which are filled during other sampling periods. This allows the frequency of sampling in areas, e.g. areas near the edges RI, R2, to be further multiplied.
- the type of evaluation for obtaining measured values of the environment can also be changed in relation to individual areas of the detection area 12 and/or in relation to the driving situation (parking, motorway, ). For example, it is possible to vary between individual frames that were recorded during a sampling period A, B and the combination of frames that were obtained from two or more sampling periods.
- the type of sampling does not have to be changed for this and therefore does not have to be validated multiple times in the development phase.
- the number of nested frames i.e. the sampling periods, can be adapted in particular to the angular ranges 16 and angular velocity of the change of the angle 20.
- the described principle of alternating sampling periods with respective error ranges is applicable to ID deflected systems and 2D deflected systems advantageous because information from the vicinity of the current sampling point or the current scanning line can be obtained quickly.
- the method described can be combined with methods which each scan the detection area 12 without any gaps. It is then possible to switch between the different modes, which is also possible during operation, for example.
- One implementation is possible, for example, by delaying the trigger signals for the pulses of the optical signal L.
- modes are also conceivable in which frames which completely scan the detection area 12 are combined with frames which leave gaps in the scanning. This allows, for example, certain areas of the detection area 12 to be specifically captured with more resolution.
- FIG. 5 shows a schematic representation of a vehicle 100, for example a passenger car.
- the lidar system 30 is arranged in a front area of the vehicle 100.
- the lidar system 30 has the optical transmitting unit 32 and the optical receiving unit 34.
- the deflection device 10 is arranged between the transmitting unit 32 and the receiving unit 34.
- the deflection device 10 can deflect the optical signal L sent by the optical transmitting unit 32 in such a way that the detection area 12 is scanned step by step in the scanning direction 18. In this case, scanning can be carried out from a first edge RI of the scanning area 12 to a second edge R2 of the scanning area 12.
- the receiving unit 34 can have a receiving sensor for receiving the optical signal L.
- the receiving sensor can have, for example, at least one photodiode or at least one charge-coupled semiconductor component, e.g. a charge-coupled device (CCD), for receiving the optical signal L.
- CCD charge-coupled device
- the CCD can be designed as a two-dimensional field. Pixels of the two-dimensional field can be activated to receive the optical signal, whereby the activation of the pixels is possible individually and/or in groups.
- the control unit 36 can evaluate the optical signal L that is sent into the detection area 12 and received from the detection area 12.
- the control unit 36 can also control the transmission process in the transmitting unit 32, the receiving process in the receiving unit 34 and, if applicable, the rotational movement of the mirror 14 can be monitored and controlled.
- the detection area 12 is located in front of the front area of the vehicle 100. In the example shown, this means that an area in the direction of travel in front of the vehicle 100 can be monitored. It is also possible to arrange the lidar system 30 in other areas of the vehicle 100, for example in the rear area and/or in side areas. It is also possible to arrange several lidar systems 30 on the vehicle 100, in particular in corner areas of the vehicle 100. With the lidar system 30, stationary or moving objects O, in particular vehicles, people, animals, plants, obstacles, road surface irregularities, in particular potholes or stones, road markings, traffic signs, open spaces, in particular parking spaces, precipitation or the like, can be detected in the detection area 12.
- stationary or moving objects O in particular vehicles, people, animals, plants, obstacles, road surface irregularities, in particular potholes or stones, road markings, traffic signs, open spaces, in particular parking spaces, precipitation or the like, can be detected in the detection area 12.
