Abstract
Description
Technical Field
[0001] This disclosure relates to a vehicle warning technology, and more particularly to a cabin warning recognition device. Background Technology
[0002] Construction vehicles such as excavators and dump trucks should be equipped with warning lights for reversing or rotating and buzzers to alert surrounding personnel and prevent collisions during operation. However, such warning devices only alert surrounding personnel and do not provide operators with more complete information about potential hazards, making it difficult for operators to effectively monitor changes in the work environment, such as personnel suddenly entering the working radius of the construction vehicle.
[0003] Therefore, there is an urgent need for a warning system for engineering vehicles to provide operators with more complete information about the working environment. Utility Model Content
[0004] One objective of this disclosure is to provide a cockpit warning and recognition device whose processor can receive surrounding images captured by multiple cameras, combine these images to form a surround view image of the engineering vehicle, and then perform image recognition processing on the surround view image to identify the presence of hazardous objects in the surround view image, as well as the speed and direction of movement of the hazardous objects. This allows the determination of the risk status of the engineering vehicle, which is then displayed on a display device inside the cockpit. Therefore, the cockpit warning and recognition device can provide operators inside the cockpit with more complete information about surrounding hazardous objects, enabling operators to effectively control changes in the working environment and significantly reduce operational risks.
[0005] In accordance with the aforementioned objectives of this disclosure, a cockpit warning and recognition device is proposed. This cockpit warning and recognition device includes several cameras, a processor, and a display device. These cameras are mounted on an engineering vehicle, each camera configured to capture images of the vehicle's surroundings. The processor is located within the cockpit of the engineering vehicle and is signal-connected to the cameras. The processor is configured to receive the surrounding images, assemble these images into a surround-view image of the engineering vehicle, and perform image recognition processing on the surround-view image to obtain the risk status of the engineering vehicle. The display device is located within the cockpit and is signal-connected to the processor. The display device is configured to receive and display the surround-view image. The processor controls the display device to display a corresponding image on the surround-view image based on the risk status of the engineering vehicle.
[0006] According to one embodiment of this disclosure, the number of cameras is 4, and the shooting range of each camera is 190 degrees.
[0007] According to one embodiment of the present disclosure, the processor is disposed in a display device, and the display device has a touch screen.
[0008] According to one embodiment of this disclosure, the aforementioned surround view image includes an image of the engineering vehicle. The processor is further configured to divide the surround view image into several regions, and these regions surround the image of the engineering vehicle. A corresponding frame includes several sub-frames corresponding to these regions respectively. The processor independently controls these sub-frames.
[0009] According to one embodiment of this disclosure, each of the above-mentioned sub-screens includes several warning patterns arranged from beside the image of the engineering vehicle toward a direction away from the image.
[0010] According to one embodiment of this disclosure, the warning patterns have different colors in each sub-screen.
[0011] According to one embodiment of this disclosure, when the risk status of the engineering vehicle is that at least one hazardous object appears in a region of the surround view image, the processor controls the display device to display the corresponding sub-screen on that region. When the risk status of the engineering vehicle is that there are no hazardous objects in that region of the surround view image, the processor controls the display device to turn off the corresponding sub-screen for that region.
[0012] According to one embodiment of this disclosure, when the aforementioned hazardous object enters this area and moves toward the image of the engineering vehicle, the processor controls the display device to display a corresponding sub-screen on this area, so that the warning patterns on this sub-screen are displayed one by one at 100% brightness as the hazardous object approaches. These warning patterns gradually fade away within a preset time after the hazardous object moves away. The warning pattern at the location where the hazardous object is stationary is displayed with 50% transparency.
[0013] According to one embodiment of this disclosure, when the aforementioned risk object enters this area and moves toward the image at a speed greater than a preset speed, the processor controls the display device to display a corresponding sub-screen on this area, so that the warning patterns on the sub-screen are displayed one by one at 100% brightness as the risk object approaches, and these warning patterns are gradually faded off after the risk object moves away, and this cycle is repeated twice.
[0014] According to one embodiment of this disclosure, the aforementioned cockpit warning and recognition device further includes a buzzer disposed on the engineering vehicle, wherein the buzzer is signal-connected to a processor. The processor is further configured to control the buzzer to emit a warning sound when at least one hazardous object appears in the surround view image of the engineering vehicle's risk status.
[0015] According to one embodiment of this disclosure, the aforementioned cockpit warning and recognition device further includes a warning light disposed on the engineering vehicle, wherein the warning light is signal-connected to a processor. The processor is further configured to control the warning light to emit a warning light when at least one hazardous object appears in the surround view image of the engineering vehicle's risk status.

[0058] The embodiments of this disclosure are discussed in detail below. However, it will be understood that the embodiments provide many applicable concepts that can be implemented in a wide variety of specific situations. The discussed and disclosed embodiments are for illustrative purposes only and are not intended to limit the scope of this disclosure. All embodiments of this disclosure disclose a variety of different features, but these features may be implemented individually or in combination as needed.
[0059] Furthermore, the terms "first," "second," etc., used in this article do not specifically refer to order or sequence; they are merely used to distinguish elements or operations described using the same technical terms.
[0060] The spatial relationship between the two elements described in this disclosure applies not only to the orientations shown in the accompanying drawings, but also to orientations not shown in the drawings, such as inverted orientations. Furthermore, the terms "connection," "electrical connection," or similar expressions used in this disclosure to refer to two components are not limited to a direct or electrical connection, but may also include indirect or electrical connections as needed.
[0061] Please refer to Figure 1 and Figure 2 The diagram shows a block diagram of a cockpit warning and identification device 100 according to an embodiment of the present disclosure, and a schematic diagram of an engineering vehicle 500. The cockpit warning and identification device 100 is applied to the engineering vehicle 500 to provide operators in the cockpit 510 of the engineering vehicle 500 with more comprehensive risk information, thereby improving the safety of the engineering vehicle 500 during operation. For example, the engineering vehicle 500 may be an excavator, bulldozer, or forklift, etc.
[0062] The cockpit warning and recognition device 100 mainly includes multiple cameras 200, a processor 300, and a display device 400. These cameras 200 are mounted on the engineering vehicle 500. For example, these cameras 200 can be mounted on the front, rear, left, and right sides of the cockpit 510 of the engineering vehicle 500 to capture images of the surrounding area of the engineering vehicle 500 from all four sides. In some embodiments, the number of cameras 200 is four, and the shooting range of each camera 200 is 190 degrees. Thus, the shooting range of these cameras 200 can completely cover the perimeter of the engineering vehicle 500. The number and shooting range of the cameras 200 are not limited to the above embodiments, as long as the combined shooting range of all cameras 200 can completely cover the perimeter of the engineering vehicle 500.
[0063] The processor 300 is located inside the cabin 510 of the engineering vehicle 500. The processor 300 can connect to the cameras 200 via wired or wireless transmission. In this way, the processor 300 can receive surrounding images of the engineering vehicle 500 captured by the cameras 200. Please refer to... Figure 3 This is a schematic diagram illustrating a surround view image 600 of an engineering vehicle 500 according to an embodiment of the present disclosure. The processor 300 can stitch together received peripheral images to form the surround view image 600 of the engineering vehicle 500 through image processing. Figure 3In this embodiment, the surround image 600 is an octagonal image. The surround image 600 may also be an image of other shapes, such as a square, a circle, or a polygon other than a square, etc., and this disclosure is not limited thereto. The surround image 600 may include an image 500i of the engineering vehicle 500. In some embodiments, the processor 300 may divide the surround image 600 into several regions 610a to 610h, wherein these regions 610a to 610h surround the image 500i of the engineering vehicle 500. The surround image 600 is not limited to eight regions 610a to 610h; the surround image 600 may be divided according to usage requirements, and this disclosure is not limited thereto.
[0064] The processor 300 can further perform image recognition processing on the surround view image 600 to identify whether a risk object RO appears in the surround view image 600, the moving speed of the risk object RO, and the distance between the risk object RO and the image 500i of the engineering vehicle 500, in order to obtain the risk status of the engineering vehicle 500. For example, the processor 300 can calculate the moving speed of the risk object RO using the moving distance of the risk object RO between two frames and the display time of each frame. In addition, the processor 300 can directly identify the distance between the risk object RO and the image 500i of the engineering vehicle 500 in the surround view image 600 to obtain the distance between the risk object RO and the engineering vehicle 500.
[0065] In some embodiments, the processor 300 is connected to the control system of the cockpit 510 of the engineering vehicle 500 via a wired or wireless signal connection, and can receive operational information from the engineering vehicle 500. For example, the processor 300 can obtain rotation information, movement information, and implement operation information of the engineering vehicle 500 from the control system of the cockpit 510. Implement operation information may include, for example, information on the digging operation of an excavator, information on the bulldozing and shoveling operation of a bulldozer, and information on the lifting and lowering of the forklift of a stacker. Since the risk status of the engineering vehicle 500 is higher when it is rotating, moving, and / or operating than when it is stationary, the processor 300 can make a more in-depth judgment on the risk status of the engineering vehicle 500 based on this operational information, thereby reducing the operational risk of the engineering vehicle 500.
[0066] The processor 300 can predict whether the hazardous object RO will enter the working range of the engineering vehicle 500, and the time it will take for the hazardous object RO to enter the working range of the engineering vehicle 500, based on the moving speed and direction of the hazardous object RO. When making the above predictions, the processor 300 can further coordinate with the operation information of the engineering vehicle 500.
[0067] The display device 400 is disposed within the cabin 510 of the engineering vehicle 500 and can be signal-connected to the processor 300 via wired or wireless transmission. In some embodiments, the processor 300 may be disposed within the display device 400 and electrically connected to the display device 400 via physical wiring. The display device 400 can receive and display the surround view image 600 from the processor 300. In some embodiments, such as Figure 3 As shown, the surround view image 600 includes a display area 620, and the range R of the surround view image 600 formed by the surrounding images captured by the camera 200 is larger than the display area 620. That is, the detection range of the camera 200 is larger than the range displayed by the display device 400. Therefore, the processor 300 can identify the risky object RO when it enters the range R of the surround view image 600 but before entering the display area 620.
[0068] The processor 300 can further control the display device 400 to display a corresponding screen 700 on the surround view image 600 based on the risk status of the engineering vehicle 500 obtained through image recognition processing. The corresponding screen 700 may contain multiple sub-screens, such as sub-screens 710a to 710h. Figure 3 In the illustrated embodiment, the panoramic image 600 is divided into eight regions 610a to 610h, and the corresponding screen 700 is divided into eight sub-screens 710a to 710h, each corresponding to a region 610a to 610h. That is, the number of sub-screens 710a to 710h is equal to the number of regions 610a to 610h. The processor 300 can independently control these sub-screens 710a to 710h. For example, when the hazardous substance RO enters region 610h of the panoramic image 600, the processor 300 controls the display device 400 to display the corresponding sub-screen 710h of the screen 700 on region 610h.
[0069] In some embodiments, each sub-screen 710a-710h includes multiple warning patterns, such as warning patterns 712, 714, and 716. Warning patterns 712, 714, and 716 may be an OSD (On-Screen Display). The number of warning patterns in each sub-screen 710a-710h can be adjusted as needed, and is not limited to three. Figure 3 As shown, warning symbols 712, 714, and 716 are arranged from beside the image 500i of the engineering vehicle 500 in a direction away from the image 500i. Specifically, warning symbol 712 is closest to the image 500i of the engineering vehicle 500, warning symbol 716 is farthest from the image 500i, and warning symbol 714 is between warning symbols 712 and 716. In some embodiments, warning symbols 712, 714, and 716 have different colors to facilitate operators' visual identification of the level of risk. For example, warning symbol 712 may be red, warning symbol 714 may be orange, and warning symbol 716 may be green.
[0070] Please refer to the following at the same time Figure 3 and Figure 4 ,in Figure 4 This is a schematic diagram showing warning patterns 712, 714, and 716 of a sub-screen 710h corresponding to a risk status of an engineering vehicle 500 according to an embodiment of the present disclosure. When the processor 300 obtains that the risk status of the engineering vehicle 500 is such that at least one hazardous object RO appears in one of the regions 610a to 610h of the surround view image 600, the processor 300 controls the display device 400 to display the corresponding sub-screens 710a to 710h on those regions 610a to 610h. For example, when a hazardous object RO appears in region 610h of the surround view image 600, the processor 300 controls the display device 400 to display sub-screen 710h on region 610h. In some embodiments, when the hazardous object RO enters the area 610h and moves toward the image 500i of the engineering vehicle 500, the processor 300 controls the display device 400 to display a corresponding sub-screen 710h on the area 610h, and causes the warning patterns 716, 714, and 712 on the sub-screen 710h to be displayed one by one at 100% brightness as the hazardous object RO approaches, that is, directly from 0% brightness to 100%. After the hazardous object RO moves away, these warning patterns 716, 714, and 712 gradually fade away within a preset time, such as 5 seconds, by reducing the brightness from 100% to 50%.
[0071] Specifically, when the hazardous object RO enters area 610h and approaches the corresponding position of warning pattern 716, the processor 300 controls the display device 400 to display warning pattern 716 in sub-screen 710h at 100% brightness in area 610h. As the hazardous object RO continues to move towards the image 500i of the engineering vehicle 500 and reaches the corresponding position of warning pattern 714, the processor 300 controls the display device 400 to display warning pattern 714 in sub-screen 710h at 100% brightness, and causes warning pattern 716 to gradually fade from 100% brightness to 50% within a preset time. When the hazardous object RO continues to move to the corresponding position of warning pattern 712, the processor 300 controls the display device 400 to display warning pattern 712 in sub-screen 710h at 100% brightness, and causes warning pattern 714 to gradually fade from 100% brightness to 50% within this preset time, or gradually fade and turn off. If the hazardous substance RO eventually stops at warning pattern 712, warning pattern 712 is displayed with, for example, 50% transparency.
[0072] When the risk status of the engineering vehicle 500 indicates that there is no risky object RO in one of the areas 610a to 610h of the surround view image 600, the processor 300 controls the display device 400 to turn off the corresponding sub-screen 710a to 710h of that area 610a to 610h. For example, when there is no risky object RO in area 610h, the processor 300 controls the display device 400 to turn off the corresponding sub-screen 710h.
[0073] Please refer to the following at the same time Figure 3 and Figure 5 ,in Figure 5 This is a schematic diagram showing warning patterns 712, 714, and 716 on a sub-screen 710h of a corresponding screen 700 representing a risk state of another engineering vehicle 500 according to an embodiment of this disclosure. When a hazardous object RO enters one of the areas 610a to 610h, such as area 610h, and moves rapidly toward the image 500i of the engineering vehicle 500 at a speed greater than a preset speed, the processor 300 controls the display device 400 to display the corresponding sub-screen 710h on area 610h. The processor 300 controls the warning patterns 716, 714, and 712 on the sub-screen 710h to be displayed one by one at 100% brightness as the hazardous object RO approaches, and then gradually fades or turns off these warning patterns 716, 714, and 712 as the hazardous object RO moves away, by gradually decreasing the brightness from 100% to 50%. This cycle repeats twice. The warning symbols 712, 714, or 716 corresponding to the last known location of the hazardous material RO are displayed with, for example, 50% transparency. Therefore, the cabin warning recognition device 100 can provide different warning methods depending on the movement conditions of the hazardous material RO.
[0074] The screen of the display device 400 can be a touch screen. Therefore, the screen of the display device 400 can serve as a human-machine interface to facilitate the image recognition processing settings of the driver setting processor 300 and the display settings of the display device 400.
[0075] Please refer to Figure 6 This is a block diagram illustrating a cabin warning recognition device 100a according to another embodiment of the present disclosure. The cabin warning recognition device 100a of this embodiment has a generally similar architecture to the cabin warning recognition device 100 of the commercial vehicle described above, the difference being that the cabin warning recognition device 100a also includes a buzzer 800 and a warning light 900.
[0076] Please refer to the above as well. Figure 2 and Figure 3A buzzer 800 is mounted on the engineering vehicle 500 and can be connected to the processor 300 via wired or wireless transmission. In some embodiments, the buzzer 800 is independent of the display device 400 but can be electrically connected to the display device 400 via a line. The buzzer 800 can also be electrically connected to the electrical system within the cabin 510 of the engineering vehicle 500. When the processor 300 identifies a risk object RO in any of the areas 610a to 610h of the surround view image 600 as a risk state of the engineering vehicle 500, it controls the buzzer 800 to emit a warning sound to alert the operator.
[0077] The warning light 900 is mounted on the engineering vehicle 500 and can be connected to the processor 300 via wired or wireless transmission. In some embodiments, the warning light 900 can be externally connected to the display device 400 via a wire. When the processor 300 identifies a risk object RO in any of the areas 610a to 610h of the surround view image 600 as a risk state of the engineering vehicle 500, it controls the warning light 900 to emit a warning light to alert the operator.
[0078] In some embodiments, when the engineering vehicle 500 is not moving, the display device 400 may only display the surround view image 600 and the corresponding screen 700. However, when the engineering vehicle 500 is not moving, in addition to displaying the surround view image 600 and the corresponding screen 700, a buzzer 800 and a warning light 900 may also be used to provide a warning. When the engineering vehicle 500 moves, rotates, and / or operates, in addition to displaying the surround view image 600 and the corresponding screen 700 on the display device 400, it is preferable to use a buzzer 800 and a warning light 900 to provide a warning.
[0079] As can be seen from the above embodiments, one advantage of this disclosure is that the processor of the cockpit warning and recognition device can receive surrounding images captured by multiple cameras, combine these images into a surround view image of the engineering vehicle, and then perform image recognition processing on the surround view image to identify whether there are hazardous objects in the surround view image, as well as the speed and direction of movement of the hazardous objects. This allows the determination of the risk status of the engineering vehicle, which is then displayed on the display device in the cockpit. Therefore, the cockpit warning and recognition device can provide operators in the cockpit with more complete information about surrounding hazardous objects, enabling operators to effectively control changes in the working environment and significantly reduce operational risks.
[0080] Although this disclosure has been disclosed above with reference to embodiments, it is not intended to limit this disclosure. Any person skilled in the art can make various changes and modifications without departing from the concept and scope of this disclosure. Therefore, the scope of protection of this disclosure shall be determined by the claims.
