Detailed Description
The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration and explanation only, not limitation.
In the description of the present invention, it should be noted that the terms "connected" and "connected" are to be interpreted broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected, unless explicitly stated or limited otherwise; either directly or indirectly through intervening media, either internally or in any combination thereof. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.
In a basic embodiment of the present invention, as shown in fig. 1, the present invention provides a vehicle contour display system, which includes a projection image display module, a projection position adjusting module and a control module, wherein the control module is respectively connected to the projection image display module and the projection position adjusting module in a communication manner; the control module is used for: controlling the projection position adjusting module to project the target image on the ground around the vehicle body; controlling the projection position adjusting module to change the projection position of the target image on the ground; and controlling the output power of a projection light source of the projection image display module and the size and the shape of a target image.
The control module can adopt an existing controller which can be used for processing information and controlling the operation of each mechanism element, preferably a vehicle Body Controller (BCM), and can control the power of the laser output by the laser light source unit, namely the brightness of a target image finally irradiated to the periphery of a vehicle body. The projection position of the target image can be preset, and can be self-adaptive to be adjusted to a proper position according to the actual situation.
It should be noted that fig. 4 shows an example of a process in which an image emitted through the projection image display module is reflected to a road surface by a reflector in the projection position adjustment module and a projection position of the image changes, and although the light pattern of the image shown in fig. 4 is a rectangle, the light pattern of the emitted image is not limited to the rectangle, but may be other shapes, such as a circle, a trapezoid, a triangle, and even some singular shapes, such as a skeleton pattern, which can better attract the attention of other vehicle drivers or pedestrians and make the outline showing effect more prominent; the projection of the images may be continuous, forming an integral light pattern around the vehicle body, or may be sequential dynamic images, preferably sequential dynamic images; that is, as long as the projected image can perform the outline-showing function, even if the projected image is somewhat distorted, fig. 6 shows a form of distortion of the projected image without compensation processing; as a preferred embodiment, the light pattern of the outgoing image is rectangular, and further, the brightness and the shape of the outgoing image are consistent; therefore, when the projection position adjusting module works and needs to project and move the image to a specific position, the control module can control the projection position adjusting module to adjust the projection position of the target image on the ground.
In the basic technical scheme, the control module controls the projection position adjusting module to output laser to form static images or dynamic images with different light shapes to be projected onto the ground around the vehicle body, the display position of the projection position adjusting module can be adjusted along with the width of the vehicle body, the outline showing range can be enlarged, other road users can see the outline of the vehicle more easily, the vehicle can be found in advance, and therefore the safety factor in the driving process is effectively improved; the control module can enable the projection image to move along the direction of the vehicle body by controlling the projection position adjusting module, so that the outline of the vehicle can be clearly displayed, meanwhile, the outline displaying range is enlarged, the influence of a display blind area is weakened, and the driving safety coefficient is further improved; meanwhile, the output power of the laser and the size and the shape of the target image can be controlled by controlling the projection image display module, so that the projection image is guaranteed to be always clearly visible in the moving process and cannot be distorted.
The projection image display module can adopt a multi-pixel light source, and the color, the shape and the size of a projection image emitted by the projection image display module are controlled by respectively controlling the color and the brightness of each pixel light source. In one embodiment of the present invention, as shown in fig. 3, the projection image display module includes a laser light source unit and a scanning imaging unit, and the control module is electrically connected to the laser light source unit to control the output power of the laser light source; the control module is electrically connected with the scanning imaging unit to control the size and the shape of the target image. The scanning imaging unit can adopt the existing MEMS (micro electro mechanical system) micro-mirror or DMD (digital micro-mirror), preferably, the MEMS micro-mirror, after the laser irradiates on the MEMS micro-mirror, according to different control programs, the micro-mirror adjusts the angle at high speed in the fast and slow axis directions, and the laser reflected by the MEMS micro-mirror forms images with different shapes and sizes. Specifically, the laser light source unit outputs modulated light signals according to a time sequence, the scanning imaging unit adopts a progressive scanning mode or a vector scanning mode, the control module controls the angle and the frequency of the MEMS micro-mirror, each pattern has different control programs and parameters thereof, and the different control programs comprise electric circuit control. Preferably, in order to effectively improve the light efficiency, a laser collimation unit is arranged between the laser light source unit and the scanning imaging unit, as shown in fig. 3, wherein the laser collimation unit may be an optical element capable of converging light, such as a focusing lens, a collimator, and the like.
In an embodiment of the present invention, as shown in fig. 4, a mirror is disposed in the projection position adjusting module, the mirror is adapted to project the target image on the ground around the vehicle, and the projection position adjusting module adjusts the projection position of the target image on the ground by adjusting a rotation angle of the mirror. Specifically, the mirror may be connected to a driving device, and the projection position adjusting module may control the rotation angle of the mirror by controlling the rotation angle of the driving device, so as to further control the projection position of the target image around the vehicle body. The driving device can be a stepping motor or a structure or a machine which can drive the reflecting mirror to rotate for a specific angle.
When the projection position adjusting module works, the projection position of the target image around the vehicle body is preset, the control module controls the rotation angle of the reflector to project the target image onto the corresponding projection position, or the projection position adjusting module directly projects the target image onto the ground around the vehicle; when the projection position of the target image needs to be moved, the control module calculates the angle of the reflector which needs to be rotated according to the position of the projection image which needs to be moved, and then controls the reflector to rotate to the corresponding angle, so that the movement of the projection position of the target image is realized. In the process, the control module can also calculate the output power of the light source and the size and the shape of the target image according to the projection position, so that the phenomenon of image distortion or uneven light shape of the projected image in the process of moving the projection position of the target image is prevented.
For the sake of understanding, the basic technical solution of the present invention is further described with reference to fig. 3 to 6, wherein the initial projection position is the reflecting surface of the reflector facing vertically downwards.
As shown in fig. 3, the laser output from the laser light source unit is received by the scanning and imaging unit and is scanned and imaged, the laser emitted from the scanning and imaging unit is reflected onto the reflecting mirror, the laser emitted from the scanning and imaging unit is irradiated onto the reflecting mirror with the horizontal field angle a and the vertical field angle B, the light reflected by the reflecting mirror is still emitted with the horizontal field angle a and the vertical field angle B, and the original horizontal frame s and the vertical frame t are emitted with the original angle, and the specific light pattern is shown in fig. 5. In a specific embodiment, the reflector rotates around an axis Z, preferably, the axis Z is collinear with the principal ray h, and as the reflection angle of the reflector is changed continuously, a target image with a continuously changed position appears on the road surface around the vehicle body, as shown in fig. 4, in a projection area, an initial position projected image before rotation is D0, after the reflector rotates for a certain angle, a corresponding projected image is D1, and after n rotations, the projected image moves to Dn; if the image is not compensated in the rotating process, the projected image moves in the arc direction as shown in fig. 6, and the projected image obtained in this way is distorted, so that the outline showing effect can be achieved, however, in order to achieve a better outline showing effect, the integrity and non-distortion of the image need to be ensured, the geometry of the projected image and the output power of the laser need to be adjusted, and of course, it can be understood that a person skilled in the art can also reversely move the projected image in the original moving direction by reversely rotating the mirror, or move the projected image in other required manners; in addition, the laser light source unit and the scanning imaging unit form an afocal projection system, compared with a projection device needing focusing, the afocal projection system is clear at any distance, only the difference of imaging sizes exists, the output efficiency of the system is basically limited by the light extraction efficiency of the laser light source unit and the reflectivity of an MEMS (micro-electromechanical system) micro-mirror, and the afocal projection system is more convenient to design and use.
In an embodiment of the present invention, as shown in fig. 2, the control module includes an information acquisition unit, an interactive logic unit, a driving device control unit, and an image output control unit; the image output control unit is electrically connected with the laser light source unit so as to control the output power of the laser light source; the image output control unit is electrically connected with the scanning imaging unit so as to control the size and the shape of the target image; the driving device control unit is electrically connected with the projection position adjusting module so as to adjust the projection position of the target image on the ground; the interactive logic unit can calculate the rotation angle of the reflector, the output power of the laser light source and the size and shape of the target image according to the information acquired by the information acquisition unit and the preset projection position of the target image on the ground, and controls the rotation angle of the reflector and the output power of the laser light source and the size and shape of the target image through the driving device control unit and the image output control unit.
Specifically, taking the whole vehicle contour display system as an example, the position of the projected image moves along the vehicle body direction in the whole process, and moves from one position to another position, and the preset projection position refers to the another position. The control module confirms the rotation angle of the reflector according to the conversion of the two positions. In the whole projection process, the distance of the projected image from the vehicle body can be adaptively adjusted according to the condition of the vehicle body and the condition of the surrounding environment of the vehicle body, such as adjusting the distance of the projected image from the vehicle body by adjusting the angle of the image emitted by the projection unit (such as the emission angle of the MEMS) or adjusting the distance of the projected image from the vehicle body by other means, and the adaptive adjustment mode is not limited herein.
