Embodiment 1

[0053] like figure 1 , figure 2 , an image-controlled vacuuming power sweeping robot 10, the sweeping robot walks on the working surface 20 and uses the vacuuming method to clean the working surface. The sweeping robot is provided with a vacuuming motor (not shown in the figure), and the vacuum cleaner motor can A motor that regulates the output power. The cleaning robot is also provided with a controller (not shown in the figure) that controls the output power of the vacuuming motor. In this embodiment, the width of the sweeping robot is 300 mm, and the length of the sweeping robot is 300 mm. A floor brush 13 is provided on the bottom surface of the cleaning robot. The cleaning width of the sweeping robot is the same as that of the sweeping robot.

[0054] There is a camera 11 at the front of the sweeping robot. In order to enable the camera to clearly obtain the image of the working surface and the image of the dust in front of the robot, the height of the camera from ...

Embodiment 2

[0057] A control method of an image-controlled vacuuming power sweeping robot, wherein the sweeping robot is the image-controlled vacuuming power sweeping robot 10 described in the first embodiment.

[0058] The sweeping robot walks on the working surface and cleans the working surface by vacuuming. The sweeping robot is provided with a camera 11, and the sweeping robot is also provided with a controller that controls the output power of the vacuuming motor; the control method includes:

[0059] Step 1: The cleaning robot acquires the image of the clean state of the work surface, and stores it in the controller as a clean reference image.

[0060] In this embodiment, the width of the work surface in the clean reference image is GW=300mm, which is equal to the width of the sweeping robot, the length of the work surface in the clean reference image is GL=300mm, and the work surface in the clean reference image is a square area, such as figure 1 shown. A clean reference image is...

Embodiment 3

[0075] This embodiment is another application example of the second embodiment.

[0076] like Figure 7 , the working face in this embodiment is the working face with the middle tone. The clean reference image has a width of 300mm, a height of 78mm, a width of 850 pixels, a height of 221 pixels, and a resolution of 72DPI.

[0077] The control method of this embodiment includes:

[0078] In step one:

[0079] The controller obtains the white reference threshold and the black reference threshold of the clean reference image, and the threshold value ranges from 0 to 255. The method of obtaining the white reference threshold is to perform binarization processing on the clean reference image to obtain the maximum white threshold value. Using the trial calculation method, with a 4-bit step value, when the threshold value is 92, the black in the binarized image will be black. The number of pixels is 0; when the threshold is 96, the number of black pixels in the binarized image is...

Abstract

The invention relates to a floor mopping robot controlling dust suction power by virtue of an image and a control method. The floor mopping robot walks on a working surface and sweeps the working surface by adopting a dust suction way, a camera is arranged at the front edge of the floor mopping robot, the floor mopping robot is provided with a controller, the controller is in charge of receiving and processing the image, and the controller is also used for controlling output power of a dust suction motor. The control method comprises the following steps: acquiring the image of the working surface in a clean state; when the floor mopping robot sweeps the working surface, shooting an image of the working surface in front of the floor mopping robot while walking by the camera; and comparing a clean reference image with a working image by the controller, and controlling the output power of the dust suction motor according to a comparison result. The floor mopping robot provided by the invention has the advantages that granular dust particles on the working surface are found by photographing, controllable power of the dust suction motor of the floor mopping robot is realized, power consumption of the floor mopping robot in operation can be obviously reduced, and endurance time of a battery is prolonged.

Description

technical field [0001] The invention belongs to a sweeping robot, in particular to an image-controlled sweeping power sweeping robot and a control method. Background technique [0002] At present, more and more robot vacuum cleaners are entering the family life, and the degree of intelligence of the robot vacuum cleaner is also getting higher and higher. An important function of the sweeping robot is to clean the garbage at home and collect the garbage into its dust box. In order to make the robot walk and work flexibly, the current sweeping robots are generally powered by rechargeable batteries. One of the main technical obstacles faced by the sweeping robots is the battery life. The vacuum cleaner motor of the sweeping robot is its main power-consuming component. Usually, in order to obtain the best cleaning effect of the sweeping robot, the user generally sets the suction of the sweeping robot to the highest level, so as to pass the large negative impact generated by the...
