As shown in fig. 1-5, the embodiment of the utility model provides a three-dimensional detection lighting system, long-distance battle array receiver and two car lights that integrate with LiDAR module 20, LiDAR module 20 installs inside the car light, each LiDAR module 20 all includes closely receiver and laser instrument, two car lights are surveyed through the laser instrument transmission respectively and are used laser signal (specifically be area array laser, can be visible light or infrared laser), two closely the receiver correspond the laser signal who receives two car lights and send respectively, long-distance receiver 30 is used for receiving the superimposed signal that the overlap region between the laser signal that two car lights sent produced, long-distance receiver 30 opens when the superimposed signal reflects back the automobile body, and close before next superimposed signal transmission.
The three-dimensional detection lighting system is applied to an automobile, and particularly, can be applied to the front side of the automobile body 10, the rear side of the automobile body 10 or the three-dimensional detection lighting system arranged on the front side of the automobile body 10 and the rear side of the automobile body 10. As shown in fig. 4, when the three-dimensional detection lighting system is applied to the front side of the vehicle body 10, two lamps in the three-dimensional detection lighting system are two headlamps on the front side of the vehicle body 10. When the three-dimensional detection lighting system is applied to the rear side of the vehicle body 10, two lamps in the three-dimensional detection lighting system are two rear lamps on the rear side of the vehicle body 10. As shown in fig. 5, when the three-dimensional detection illumination systems are arranged on both the front side and the rear side of the vehicle body 10, there are two sets of the three-dimensional detection illumination systems, one of which is applied to the front side, and the two lamps in the three-dimensional detection illumination system are the two headlamps on the front side of the vehicle body 10; the other set is applied to the rear side of the vehicle body 10, and the two vehicle lights in the three-dimensional detection lighting system are the two rear lights on the rear side of the vehicle body 10. The remote receiver 30 may be mounted inside the lamp of the automobile, on the bumper, behind the windshield, or the like. Preferably, the remote receiver 30 is located in the area between two vehicle lights.
Specifically, as shown in fig. 1, the overlapping area of the laser signals emitted by the lasers in the lamps on the two sides is an included angle α, the distance range is D2, and the area of the included angle α is mainly used for detecting the middle and long distance detection of the lane in front of the vehicle, this area is an independent area array receiving device (i.e., the long distance receiver 30), the long distance receiver 30 only needs to detect the detection signal within the D2 distance range or within the D1 distance range or within the D1 distance range.
In the present application, the remote receiver 30 only detects a remote target object, and a receiving delay is preset when receiving the laser pulse, so that the interference signal can be effectively filtered, and the accuracy of remote detection is ensured. (for example, two LiDAR modules 20 were responsible for a detection range of 0-50 m, so detection in the 0-50 m area was done by LiDAR modules 20 on both sides, and the remote receiver 30 was only turned on for a distance range of 50-200 m.)
As shown in FIG. 1, in the emission time of non-overlapping pulses, for the detection of near-side objects, the LiDAR modules 20 in the left and right car lamps are adopted to respectively emit and receive laser signals with corresponding different wavelengths, the detection range of the LiDAR module 20 is D1, the detection range is β angular range which is smaller than the distance range of D1, and the near-distance receiver in the LiDAR module 20 receives corresponding signals, the detection range with the included angle of β is the limit of near-field detection, and the detection angle of the part is larger, so that the part is mainly used for the detection of medium and short distances and can detect more detailed characteristics of a target object.
In an optional implementation manner of this embodiment, the lasers in the two vehicle lamps are connected to the same laser driver, and one laser driver drives the two lasers simultaneously, so as to ensure consistency of laser emitting ends in the two vehicle lamps, and facilitate ensuring that the wavelengths of the lasers emitted by the two vehicle lamps are the same.
Or, in a preferred implementation manner of this embodiment, the number of the laser drivers is two, and the two laser drivers are respectively connected to the two lasers in a one-to-one correspondence manner. The laser driver is used only for drive control of the laser corresponding thereto. With this arrangement, the laser emission frequencies on both sides can be modulated by the two laser drivers, respectively, so that the emission frequencies can be made to be different.
In a specific implementation manner of this embodiment, the number of the laser drivers is two, and the two laser drivers respectively control the two lasers correspondingly, so that the wavelengths of the laser signals emitted by the vehicle lamps on the two sides are consistent, the frequencies and the pulse widths are different, and a superposition area always exists.
Further, the laser driver drives the light source in the corresponding laser in a pulse driving manner, so that the laser emits a pulse signal.
The laser signals emitted by the two lasers are pulse signals with randomly distributed pulse widths, and the pulse signals emitted by the two lasers have overlapping areas. As shown in fig. 2, P1 is a graph of a pulse signal emitted by one of the lasers, and tp1 is a pulse width of one of the pulse signals emitted by the laser; p2 is a diagram of pulse signals emitted by another laser, and tp2 is one of pulse widths of the pulse signals emitted by the laser; the P3 is formed by overlapping P1 and P2, that is, a pulse signal diagram of an overlapping signal in a laser signal overlapping region emitted by two lasers is a pulse signal pulse width tp3 formed by overlapping tp1 and tp 2. As shown in fig. 2, although the pulse signals in P1 and P2 are both randomly distributed, each pulse signal has a coincidence region, and the superimposed signal in P3 is generated correspondingly. In fig. 2, t1, t2, t3 and the like are all time intervals between two pulses in P3, and P1 and P2 are superposed to form a superposed pulse P3 with random interval time.
Further, the laser signals emitted by the lasers are respectively generated by the corresponding laser drivers in a random coding mode, and the close-range receiver only receives the laser signals emitted by the corresponding lasers.
The above arrangement has the advantages that as the laser signals emitted by the lasers in the car lamps on the two sides are respectively randomly coded, the corresponding short-distance receivers only collect the laser pulses emitted by the corresponding lasers through signal processing, so that the mutual interference between the laser signals emitted by the lasers in the two car lamps is avoided; for the laser superposition part, the laser superposition part is formed by randomly superposing the laser signals emitted by the two lasers, so that the interference of signals on two sides on the remote superposition detection part can not be caused.
In a preferred embodiment of this embodiment, the laser driver adopts the following control method for the laser:
when the vehicle is in a driving detection state, the laser driver controls the lasers to enable the emission frequencies of the two lasers to be different, and therefore interference of other detection systems can be avoided.
By the arrangement, the full-view detection capability in the steering process can be enhanced, and the accident risk under the environment of complex road conditions and vehicle conditions is reduced.
In one embodiment of this embodiment, the coverage area of the laser signals emitted by the LiDAR modules 20 on both sides can be dynamically adjusted to increase or decrease the corresponding overall detection angle under different vehicle speeds and road conditions.
As shown in fig. 3, the overlapping signal in the angle range θ c may interfere with the side detection signal of the near field to some extent, which is especially obvious when steering and other complex road conditions, and θ c is referred to as a cross-winding angle range. The angle value of theta c can be reduced through the change of the laser detection angle in the preset vehicle running safety guarantee distance D1 which is large enough, so that the signal crosstalk in the steering process is reduced, and the accuracy of object detection signals in the safety guarantee distance is enhanced.
Preferably, the three-dimensional detection illumination system provided by the present embodiment further includes angular adjustment means for adjusting the angular range of the laser signal emitted by the LiDAR module 20 to reduce the angular value of the angular range of crosstalk. Specifically, during vehicle steering, the angle adjustment mechanism reduces the angle value of the crosstalk angle by adjusting the LiDAR module 20.
In a specific embodiment of this application, angle adjusting device includes motor and telescopic link, and the motor is connected with the telescopic link, and the telescopic link is connected with the light source in the car light, and motor control telescopic link drives the light source and is close to or keeps away from the light-emitting window in the car light. The light that the light source sent is launched through the light-emitting window, and when the light source was kept away from the light-emitting window, the angular range of the signal that the light source sent reduced, and when the light source was close to the light-emitting window, the angular range of the signal that the light source sent was great.
Specifically, the output shaft of motor passes through the coupling joint with the lead screw, and the cover is equipped with the nut on the lead screw, and the nut is connected with the telescopic link, and the telescopic link is connected with the light source. So set up, the output shaft of motor rotates and can drive the lead screw and rotate to make the nut drive the telescopic link along the axial displacement of lead screw, thereby drive the light source and be close to or keep away from the light-emitting mouth.
Or the light source is arranged on the rotary table, the rotary table is connected with a first gear, a second gear is sleeved on an output shaft of the motor, the first gear is meshed with the second gear, and the diameter of the first gear is larger than that of the second gear. So set up, the output shaft of motor rotates in order to drive the carousel and rotate to drive the light source and rotate, when the light source of one side rotated to the direction that is kept away from another side light source, the angle value of crosstalk angle reduced.
Further, the motor can be in transmission connection with the telescopic rod or the first gear through the speed reducer.
In any of the above embodiments, further, anti-reflection optical elements are disposed in front of the long-distance receiver 30 and the short-distance receiver, and the reflected laser signals pass through the anti-reflection optical elements and then are incident on the corresponding long-distance receiver 30 or the short-distance receiver, the anti-reflection optical elements may be optical lenses or lens sets, specifically, the field angle of the anti-reflection optical elements disposed in front of the long-distance receiver 30 matches the included angle α of the overlapping region of the laser signals emitted by the lasers in the vehicle lamps on both sides.
Further, when the three-dimensional probing lighting System of the present embodiment is applied to an automobile, the three-dimensional probing lighting System can be used in cooperation with an up-down dimming System and a follow-up steering System (AFS) connected to the lamps in the automobile, so that the up-down dimming System and the follow-up steering System can be used for performing up-down, left-right dimming on the three-dimensional probing lighting System. The stable detection angle can be ensured under the conditions of vehicle bump, steering, uneven load and the like.
