[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0025] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0026] like Figure 1 As shown, a lighting effect control system is provided in Embodiment 1 of the present invention. The lighting effect control system includes: an image acquisition device 10 and a controller 20.

[0027] For example, the image acquisition device 10 is configured to acquire an image 30 of a target object, which is a dimmable lamp. The image acquisition device 10 includes a digital camera. In some embodiments, a background region 32 can be set in the image 30 of the target object, and the background region 32 can be distributed at any location in the image 30 of the target object other than the target object 31, or it can be a region covering the outside of the target object after being enlarged to a certain scale. Typically, for better visual experience for the user, the background region 32 is the region within the target region 30 other than the region 31 associated with the target object in the image. The background region 32 and the region 31 associated with the target object in the image allow the computer to identify differences in target parameters between the two regions.

[0028] In some embodiments, the region 31 associated with the target object in the image can be determined by recognizing the contour of the target object within the region 31 associated with the target object in the image. For example, when the target object in the region 31 associated with the target object in the image is not working, an image of the region 31 associated with the target object in the image is acquired. After binarizing the target image, each pixel is assigned a value of 0 and 1 to represent a black point and a white point, respectively. Specifically, black points and white points can be determined according to the grayscale value of the pixel, which will be described in detail below when discussing grayscale values. Among them, black points are contour points, and white points are non-contour points. A complex network is used to model the shape contour, and then a network model is performed on the contour point set. A connecting edge is added between each contour point in the image 30 of the acquired target object to obtain the contour of the target object.

[0029] In some embodiments, a distance threshold may be introduced to generate a new set of connecting edges within the threshold range, thereby forming an enlarged contour that is proportionally enlarged to the outline of the target object. It is understood that the brightness of the area around the light-emitting device is affected by the light-emitting device when it is working. Therefore, in preferred embodiments, the enlarged contour is used as the region 31 associated with the target object on the image.

[0030] For example, the controller 20 is configured to acquire target parameters of region 31 and background region 32 associated with the target object in the image, and adjust the target object according to the target parameters of region 31 and background region 32 associated with the target object in the image so that the brightness of region 31 and background region 32 associated with the target object in the image is substantially the same, wherein the background region 32 includes regions in the image 30 of the target object other than the target object.

[0031] It should be noted that "largely consistent" can be understood as meaning that when the difference in target parameters between the associated region 31 and the background region 32 of the target object in the image is within a preset range, they are considered to be largely consistent. For example, the target parameters include grayscale values ​​and / or brightness values.

[0032] The image parameters of the target object image 30 include: pixel value, grayscale value, and RGB color. Here, a pixel refers to the number of pixels in the target object image 30 formed after the target object is captured by a digital camera; the number of pixels in the target object image is used as the pixel value of the target object image 30. For example, if the target object image 30 has a size of 500*338, it means the image is composed of a 500*338 pixel matrix. This target image has a width of 500 pixels and a height of 338 pixels, for a total of 500*338 = 149,000 pixel values.

[0033] The grayscale value represents the brightness of the target object in the image, that is, the color depth of a point in a black and white image. The grayscale value range is generally from 0 to 255, with 255 for white and 0 for black. Therefore, black and white images are also called grayscale images. The grayscale value refers to the brightness of a single pixel. The larger the grayscale value, the brighter it is.

[0034] When determining the outline of a target object, grayscale values ​​between 0 and 127 are usually used as black points and 128 to 255 as white points, thereby determining the distribution of pixel values ​​of 0 and 1 in the image of the target object.

[0035] The RGB color refers to the color presented by each pixel of the image of the target object. Specifically, R=G=B generally means 256 color bits. For example, RGB color (150,160,170) represents one of these colors.

[0036] Example 1 obtains target parameters of the region and background region associated with the target object in the image, and adjusts the target object according to these parameters to make the brightness of the associated region and background region approximately the same. This allows for real-time adjustment of the brightness of the region associated with the target object in the image based on the varying brightness levels in different scenes, thereby satisfying the user's visual perception of the associated region in different scenarios and improving the user experience.

[0037] like Figure 2 The diagram shown is a structural schematic of a lighting effect control system provided in Embodiment 2 of the present invention. The lighting effect system includes: a calculation unit 21, an execution unit 22, and a lighting effect adjustment unit 23.

[0038] For example, the processing unit 21 is coupled to the image acquisition device 10, and the processing unit 21 is configured to:

[0039] The contour of the target object is extracted to obtain the region 31 and background region 32 associated with the target object on the image.

[0040] The gray values ​​of the target object in the associated region 31 and the background region 32 on the image are obtained respectively, and the gray value difference between the gray values ​​of the associated region and the background region on the image is calculated.

[0041] Specifically, obtaining the grayscale values ​​of the region 31 and the background region 32 associated with the target object on the image, and calculating the grayscale difference between the grayscale values ​​of the region associated with the target object and the background region on the image, includes: determining the number of pixels in the region 31 associated with the target object on the image based on the size of the region 31 associated with the target object on the image.

[0042] For example, the area associated with the target object on the image is 100*58, which means that the area associated with the target object on the image is composed of a 100*58 pixel matrix. The width of the area associated with the target object on the image is 100 pixels long and the height is 58 pixels long, for a total of 100*58=5800 pixel values.

[0043] Obtain the grayscale value of each pixel in the region associated with the target object in the image, and calculate the average grayscale value of the pixels in the region associated with the target object in the image as the grayscale value of the region associated with the target object in the image.

[0044] For example, the grayscale value represents the numerical value of the brightness of an image, that is, the color depth of a point in a black and white image. The range is generally from 0 to 255, with white being 255 and black being 0. Therefore, a black and white image is also called a grayscale image. The grayscale value refers to the brightness of a single pixel; the larger the grayscale value, the brighter it is. For example, the sum of the grayscale values ​​of the pixels in the associated region of the target object in the image is calculated, and then the average grayscale value of the pixels in the associated region of the target object in the image is calculated. For example, if the total grayscale value is 580000, then the average grayscale value is 100.

[0045] Specifically, the grayscale values ​​of the target object in the associated region 31 and the background region 32 of the image are obtained respectively, and the grayscale difference between the associated region and the background region of the target object in the image is calculated, including:

[0046] The number of pixels in the background image is determined based on the size of the background region 32.

[0047] For example, the background area 32 has a size of 500*200, which means that the background area 32 is composed of a 500*200 pixel matrix. The width of this background area 32 is 500 pixels long and the height is 200 pixels long, with a total of 500*200=10000 pixel values.

[0048] Obtain the grayscale value of each pixel in the background region 32, and calculate the average grayscale value of the pixels in the background region 32 as the grayscale value of the background region 32.

[0049] For example, the grayscale value represents the brightness of an image, that is, the color depth of a point in a black and white image. It typically ranges from 0 to 255, with white being 255 and black being 0. Therefore, a black and white image is also called a grayscale image. The grayscale value refers to the brightness of a single pixel; a larger grayscale value indicates greater brightness. For example, the sum of the grayscale values ​​of the pixels in the background region 32 is calculated, and then the average grayscale value of the pixels in the background region 32 is calculated. For example, if the sum of the grayscale values ​​is 1,000,000, then the average grayscale value is 100.

[0050] For example, the execution unit 22 is coupled to the arithmetic unit 21, and the execution unit 22 is configured as follows:

[0051] When the grayscale difference exceeds a preset value, and the grayscale value of the region 31 associated with the target object in the image is greater than the brightness value of the background region 32, the execution unit 22 outputs a first pulse signal LED1.

[0052] When the grayscale difference exceeds a preset value, and the grayscale value of the region 31 associated with the target object in the image is less than the grayscale value of the background region 32, the execution unit 22 outputs a second pulse signal LED2.

[0053] For example, the duty cycle of the first pulse signal LED1 is smaller than the duty cycle of the second pulse signal LED2. For instance, when the grayscale value of the region 31 associated with the target object in the image is greater than the grayscale value of the background region 32, the grayscale value of the region 31 associated with the target object needs to be reduced, therefore the duty cycle of the first pulse signal LED1 is smaller. Conversely, when the grayscale value of the region 31 associated with the target object in the image is smaller than the grayscale value of the background region 32, the grayscale value of the background region 32 is larger, therefore the duty cycle of the second pulse signal LED2 is larger.

[0054] In some embodiments, the controller 20 further includes a lighting effect adjustment unit 23, which includes at least one controlled switch that is turned on or off in response to the first pulse signal LED1 or the second pulse signal LED2.

[0055] In this embodiment, the lighting effect adjustment unit 23 includes a first adjustment unit and a second adjustment unit. Of course, in some other embodiments, the lighting effect adjustment unit 23 may only include the first adjustment unit. Specifically, refer to... Figure 3The first adjustment unit includes two controlled switches, namely a first switching transistor Q22 and a second switching transistor Q2. The lighting effect adjustment unit 23 also includes a first resistor R44, a second resistor R88, a third resistor R47, a fourth resistor R46, and a fifth resistor R41. The gates of the first switching transistor Q22 and the second switching transistor Q2 are the control terminals, and the sources and drains of the first switching transistor Q22 and the second switching transistor Q2 are either the first terminal or the second terminal.

[0056] The first end of the first resistor R44 is connected to the output terminal of the execution unit 22 to receive the first pulse signal LED1 or the second pulse signal LED2. The second end of the first resistor R44 is connected to the first node S1. The first end of the second resistor R88 and the control terminal of the first switch Q22 are connected to the first node S1, and the second end of the second resistor R88 is grounded. The second end of the first switch Q22 is grounded and connected to the first end of the third resistor R47. The second end of the third resistor R47 is connected to the second node S2. The first end of the fourth resistor R46 and the control terminal of the second switch Q2 are connected to the second node S2. The second end of the fourth resistor R46 is connected to the power supply terminal. The second end of the second switch Q2 is connected to the power supply terminal. The first end of the second switch Q2 is connected to the first end of the fifth resistor R41, and the second end of the fifth resistor R41 serves as the output terminal of the first adjustment unit.

[0057] In actual operation, the first switch Q22 is an N-type transistor, and the second switch Q2 is a P-type transistor. When the first pulse signal LED1 is at a high level, the potential of the first node S1 increases. When the potential difference between the first node S1 and the second terminal of the switch reaches the turn-on voltage, the first switch Q22 turns on. After the first switch Q22 turns on, the potential of the second node S2 gradually decreases from close to the power supply voltage. When the potential difference between the second node S2 and the second terminal of the second switch Q2 reaches the turn-on voltage, the second switch Q2 turns on, and the first adjustment unit outputs an adjustment voltage to change the brightness of the dimming area 31.

[0058] See Figure 4 The second adjustment unit includes two controlled switches, namely the third switch Q23 and the fourth switch Q5. The lighting effect adjustment unit 23 also includes a sixth resistor R86, a seventh resistor R89, an eighth resistor R48, a ninth resistor R47, and a tenth resistor R42. The gates of the corresponding third switch Q23 and fourth switch Q5 are the control terminals, and the source and drain of the first switch Q22 and the second switch Q2 are either the first terminal or the second terminal.

[0059] The first end of the sixth resistor R86 is connected to the output terminal of the execution unit 22 to receive the first pulse signal LED1 or the second pulse signal LED2. The second end of the sixth resistor R86 is connected to the third node S3. The first end of the seventh resistor R89 ​​and the control terminal of the third switch Q23 are connected to the third node S3, and the second end of the seventh resistor R89 ​​is grounded. The second end of the third switch Q23 is grounded and connected to the first end of the eighth resistor R48. The second end of the eighth resistor R48 is connected to the fourth node S4. The first end of the ninth resistor R47 and the control terminal of the fourth switch Q5 are connected to the fourth node S4. The second end of the ninth resistor R47 is connected to the power supply terminal. The second end of the fourth switch Q5 is connected to the power supply terminal. The first end of the fourth switch Q5 is connected to the first end of the tenth resistor R42, and the second end of the tenth resistor R42 serves as the output terminal of the second adjustment unit.

[0060] In actual operation, the third switch Q23 is an N-type transistor, and the fourth switch Q5 is a P-type transistor. When the first pulse signal LED1 is at a high level, the potential of the third node S3 increases. When the potential difference between the third node S3 and the second terminal of the switch reaches the turn-on voltage, the third switch Q23 turns on. After the third switch Q23 turns on, the potential of the fourth node S4 gradually decreases from close to the power supply voltage. When the potential difference between the fourth node S4 and the second terminal of the fourth switch Q5 reaches the turn-on voltage, the fourth switch Q5 turns on, and the second adjustment unit outputs an adjustment voltage to change the brightness of the region 31 associated with the target object in the image.

[0061] For example, at least one dimmable target object is set in the associated region 31 on the image. In this embodiment, the lighting effect adjustment unit 23 can control two target objects simultaneously, and the target objects can also have different colors to achieve different display colors.

[0062] Example 2 involves acquiring target parameters of the region and background region associated with the target object in the image, and adjusting the target object based on these parameters to ensure that the brightness of the associated region and background region is approximately consistent. This allows for real-time adjustment of the brightness of the region associated with the target object in the image according to the varying brightness levels in different scenarios, thereby satisfying the user's visual perception of the associated region in different scenes and improving the user experience.

[0063] The lighting effect adjustment system provided by this invention can be applied to lawnmowers. Therefore, this invention provides a lawnmower, which can be various types of intelligent robots, such as sweeping robots.

[0064] Specifically, a lawnmower includes: a frame, a walking mechanism, an actuator, a drive mechanism, an imaging device, and a controller.

[0065] For example, a traveling device is mounted on the frame. An actuating device is mounted on the frame for cutting operations. A driving device is mounted on the frame for driving the traveling device and / or the actuating device.

[0066] For example, an imaging device is disposed on the rack for acquiring an image of a target object. Typically, the imaging device is disposed on the outside of the rack for better image acquisition.

[0067] A controller, mounted on the rack, is typically located inside the rack to prevent external environmental factors from affecting its normal operation. The controller performs the following operations:

[0068] Obtain target parameters for the region and background region associated with the target object in the image, and adjust the target object according to the target parameters of the region and background region 32 associated with the target object in the image so that the brightness of the region and background region associated with the target object in the image is substantially the same, wherein the background region includes the region in the image of the target object other than the target object.

[0069] In some embodiments, the region 31 associated with the target object in the image can be determined by recognizing the contour of the target object within the region 31 associated with the target object in the image. For example, when the target object in the region 31 associated with the target object in the image is not working, an image of the region 31 associated with the target object in the image is acquired. After binarizing the target image, each pixel is assigned a value of 0 and 1 to represent a black point and a white point, respectively. Specifically, black points and white points can be determined according to the grayscale value of the pixel, which will be described in detail below when discussing grayscale values. Among them, black points are contour points, and white points are non-contour points. A complex network is used to model the shape contour, and then a network model is performed on the contour point set. A connecting edge is added between each contour point in the image 30 of the acquired target object to obtain the contour of the target object.

[0070] In some embodiments, a distance threshold may be introduced to generate a new set of connecting edges within the threshold range, thereby forming an enlarged contour that is proportionally enlarged to the outline of the target object. It is understood that the brightness of the area around the light-emitting device is affected by the light-emitting device when it is working. Therefore, in preferred embodiments, the enlarged contour is used as the region 31 associated with the target object on the image.

[0071] For example, the controller 20 is configured to acquire target parameters of region 31 and background region 32 associated with the target object in the image, and adjust the target object according to the target parameters of region 31 and background region 32 associated with the target object in the image so that the brightness of region 31 and background region 32 associated with the target object in the image is substantially the same, wherein the background region 32 includes regions in the image 30 of the target object other than the target object.

[0072] It should be noted that "largely consistent" can be understood as meaning that when the difference in target parameters between the associated region 31 and the background region 32 of the target object in the image is within a preset range, they are considered to be largely consistent. For example, the target parameters include grayscale values ​​and / or brightness values.

[0073] The image parameters of the target object image 30 include: pixel value, grayscale value, and RGB color. Here, a pixel refers to the number of pixels in the target object image 30 formed after the target object is captured by a digital camera; the number of pixels in the target object image is used as the pixel value of the target object image 30. For example, if the target object image 30 has a size of 500*338, it means the image is composed of a 500*338 pixel matrix. This target image has a width of 500 pixels and a height of 338 pixels, for a total of 500*338 = 149,000 pixel values.

[0074] The grayscale value represents the brightness of the target object in the image, that is, the color depth of a point in a black and white image. The grayscale value range is generally from 0 to 255, with 255 for white and 0 for black. Therefore, black and white images are also called grayscale images. The grayscale value refers to the brightness of a single pixel. The larger the grayscale value, the brighter it is.

[0075] When determining the outline of a target object, grayscale values ​​between 0 and 127 are usually used as black points and 128 to 255 as white points, thereby determining the distribution of pixel values ​​of 0 and 1 in the image of the target object.

[0076] The RGB color refers to the color presented by each pixel of the image of the target object. Specifically, R=G=B generally means 256 color bits. For example, RGB color (150,160,170) represents one of these colors.

[0077] The lighting effect adjustment system provided by the present invention can also be applied to specific scenarios, such as stage lighting control. When the lighting adjustment system is applied to a specific scenario, the target object in the region 31 associated with the target object on the image can be of different colors.

[0078] like Figure 5As shown in the figure, this embodiment of the invention also provides a lighting effect control method, the lighting effect control method comprising:

[0079] Step S510: Obtain the image of the target object.

[0080] Step S520: Obtain target parameters of the region and background region associated with the target object in the image.

[0081] Step S530: Adjust the target object according to the target parameters of the region associated with the target object and the background region on the image so that the brightness of the region associated with the target object and the background region on the image is substantially the same, wherein the background region includes the region in the image of the target object other than the target object.

[0082] like Figure 6 As shown in the figure, this embodiment of the invention also provides a lighting effect control device, which includes: an image acquisition module 1, a brightness calculation module 2, and a lighting effect control module 3.

[0083] For example, the image acquisition module 1 is used to acquire an image of the target object.

[0084] The brightness calculation module 2 is used to obtain target parameters of the region and background region associated with the target object in the image.

[0085] The lighting effect control module 3 is used to adjust the target object according to the target parameters so that the brightness of the area associated with the target object and the background area on the image is approximately the same, wherein the background area includes the area in the image of the target object other than the target object.
