[0042] In order to make the purpose, technical solution and effect of the present invention clearer and more specific, the present invention is further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0043] This embodiment provides an elevator leveling method. When implemented, this embodiment first obtains the original image and laser image of the area to be measured, and the position to be measured includes the elevator floor, the floor floor, and the gap area between the elevator floor and the floor floor. Then, according to the original image and the laser image, the laser line segment is determined, and the floor laser line segment and the elevator laser line segment are determined according to the laser line segment. Finally, according to the floor laser line segment and the elevator laser line segment, the height difference between the floor floor and the elevator floor is determined. This embodiment can realize automatic leveling of the elevator, and the measurement result is more accurate. In addition, the leveling of this embodiment is not affected by time or human factors, and can be performed in real time, which helps to realize the monitoring of the elevator status throughout its life cycle.

[0044] Exemplary Methods

[0045] The elevator leveling method in this embodiment can be applied to a terminal device, which is an intelligent terminal product, such as a computer. Since many existing elevators are equipped with advertising devices, which are generally intelligent terminal products, the elevator leveling method of this embodiment can be applied to the existing advertising devices in the elevator to form an elevator leveling device. Specifically, Figure 1 As shown in , the elevator leveling method in this embodiment includes the following steps:

[0046] Step S100, obtaining an original image and a laser image of a region to be measured, wherein the region to be measured includes an elevator floor, a floor, and a gap region between the elevator floor and the floor.

[0047] This embodiment uses laser projection technology to measure the level of the elevator. Figure 2 and Figure 4 As shown in , the elevator leveling device in this embodiment includes a device body 100; a laser device 200 and a camera 300 arranged on the device body 100, and two laser devices 200 are arranged on both sides of the camera 300. A control device is arranged in the device body 100 in this embodiment, and the camera 300 is connected to the control device so that the control device can obtain the original image and laser image taken by the camera 300 for analysis. The laser device 200 projects a laser plane ( Figure 2 and Figure 4The area surrounded by the dotted line in the figure is the laser plane. The laser plane will reflect laser line segments in the area to be measured. The area to be measured in this embodiment includes the elevator floor, the floor, and the gap area between the elevator floor and the floor. If the height difference between the elevator floor and the floor is different, the laser line segments on the elevator floor and the floor will be misaligned. Therefore, when performing elevator leveling, this embodiment first obtains the original image and the laser image of the area to be measured. The original image is an image without laser, and the laser image is an image with laser in the area to be measured.

[0048] In one implementation, when acquiring the original image and the laser image, this embodiment includes the following steps:

[0049] Step S101, photographing the area to be tested by a preset camera to obtain the original image;

[0050] Step S102, turning on a preset laser device, and after the laser device projects a laser plane, re-photographing the area to be measured through the camera to obtain the laser image, wherein two laser devices are provided, respectively located on both sides of the camera.

[0051] In order to realize leveling of the elevator and monitor the full life cycle of the elevator, the present embodiment first needs to obtain the original image when leveling the elevator. The method of obtaining the original image in the present embodiment is based on collecting the original image through the preset camera 300. Specifically, the terminal device in the present embodiment is provided with a camera 300, and the camera 300 can collect the original image of the area to be measured, such as Figure 3 As shown in , the area to be measured includes the elevator floor, the floor of the floor, and the gap area between the elevator floor and the floor of the floor. Therefore, when the elevator door is opened, the camera 300 can capture the image of the area to be measured to obtain the original image. In specific applications, this embodiment can apply the elevator leveling method to an advertising device. Therefore, the camera 300 can be directly set in the advertising device, and then the original image of the area to be measured can be captured based on the camera 300.

[0052] Next, the laser device 200 on the control terminal device of this embodiment is started, and the laser device 200 emits a laser plane, and the projection direction of the laser device 200 is toward the ground at the elevator door, such as Figure 4As shown, the laser plane is emitted toward the area to be measured, so a laser line segment will be reflected in the area to be measured, and the area to be measured can be photographed again by the camera 300 to obtain the laser image. In this embodiment, two laser devices 200 are provided, and are respectively located on both sides of the camera 300. Of course, if the elevator leveling method of this embodiment is applied to an advertising device, the laser device 200 can be directly set in the advertising device.

[0053] When the original image and the laser image are obtained, this embodiment executes step S200 to determine laser segments according to the original image and the laser image, and to determine floor laser segments and elevator laser segments according to the laser segments.

[0054] Since the difference between the original image and the laser image is that the laser image contains laser segments reflected by the laser plane on the area to be measured, the present embodiment compares the original image with the laser image to determine the laser segments, and distinguishes between floor laser segments and elevator laser segments based on the laser segments. In the present embodiment, the floor laser segment refers to the part of the laser segment located on the floor ground, and the elevator laser segment refers to the part of the laser segment located on the elevator ground.

[0055] In one implementation, in this embodiment, when determining the elevator laser line segment and the floor laser line segment, the following steps are included:

[0056] Step S201, comparing the original image with the laser image to obtain the laser line segment;

[0057] Step S202: determining, according to the laser line segment, a portion of the laser line segment located on the floor surface of the floor, and obtaining the floor laser line segment;

[0058] Step S203: Determine, based on the laser line segment, the portion of the laser line segment located on the elevator floor, and obtain the elevator laser line segment.

[0059] Specifically, the time interval between the original image and the laser image in this embodiment is as short as possible, not exceeding 0.3 seconds, so as to ensure that the area to be measured captured by the original image and the laser image is the same area. This embodiment compares the original image with the laser image to determine the laser line segment in the laser image and the position of the laser image in the area to be measured. The laser line segment spans the floor surface, the gap area, and the elevator floor. Therefore, this embodiment can directly determine the portion of the laser line segment located on the floor surface based on the laser line segment to obtain the floor laser line segment, and determine the portion of the laser line segment located on the elevator floor based on the laser line segment to obtain the elevator laser line segment.

[0060] In one implementation, before determining the elevator laser line segment and the floor laser line segment, this embodiment will screen the laser line segment. Since what needs to be determined in the subsequent steps is the height difference between the elevator floor and the floor floor, the height difference can only be conveniently calculated when the laser line segment is a straight line. Therefore, this embodiment first needs to eliminate the laser line segment that is not a straight line. Specifically, this embodiment first obtains the curvature of the laser line segment, and then based on the curvature of the laser line segment, screens out the laser line segment that meets the curvature requirements, that is, screens out the laser line segment with a curvature of 0 to ensure that the laser line segment is a straight line, so that the elevator laser line segment and the floor laser line segment can be further obtained based on the screened laser line segment. Of course, this embodiment can also set a curvature threshold, and screen out the laser line segment that meets the curvature requirements based on the curvature threshold. This embodiment also screens out laser line segments that obviously do not meet the requirements and segments that obviously deviate from the elevator floor and the floor floor. In addition, the present embodiment further screens the elevator laser line segments and the floor laser line segments, removes the line segments that are too short, and retains only the elevator laser line segments and the floor laser line segments that have a certain length, thereby obtaining the floor laser line segments and the elevator laser line segments that meet the length requirements. Since two laser devices 200 are provided in the present embodiment, two laser images are obtained based on the two laser devices 200, and then two laser line segments are obtained, and then the two laser line segments are analyzed, so that in the subsequent steps, two different height differences can be calculated based on two different elevator lasers and stair lasers, and the height difference can be determined more accurately through two measurements.

[0061] After obtaining the elevator laser line segment and the floor laser line segment, this embodiment may execute step S300 to determine the height difference between the floor surface and the elevator surface according to the floor laser line segment and the elevator laser line segment.

[0062] based on Figure 2 As shown in the schematic diagram, this embodiment can determine whether the elevator laser segment and the floor laser segment are misaligned based on the elevator laser segment and the floor laser segment. If misaligned, it means that there is a height difference between the elevator ground and the floor ground, and the height difference is further calculated to complete the elevator leveling.

[0063] In one implementation, this embodiment includes the following steps when determining the height difference:

[0064] Step S301: If the floor laser line segment is misaligned with the elevator laser line segment, it is determined that there is a height difference between the floor surface and the elevator surface;

[0065] Step S302, respectively obtaining a first distance between the laser device and the floor laser line segment, and a second distance between the laser device and the elevator laser line segment;

[0066] Step S303: Obtain the height difference according to the first distance and the second distance.

[0067] Specifically, this embodiment determines whether misalignment occurs based on the floor laser line segment and the elevator laser line segment. If misalignment occurs, it is determined that there is a height difference between the floor and the elevator floor. At this time, in order to monitor the safety and overall life cycle of the elevator, it is necessary to calculate the height difference. Therefore, this embodiment can use the positional relationship between the camera 300 and the floor laser line segment and the elevator laser line segment for calculation. First, the first distance between the laser device 200 and the floor laser line segment is obtained; then the second distance between the laser device 200 and the elevator laser line segment. The first distance and the second distance obtained at this time are the hypotenuses of the triangle, respectively. Therefore, based on the Pythagorean theorem of the right triangle, the height from the elevator floor to the laser device 200 and the height from the floor to the laser device 200 can be calculated respectively, and then the height difference between the floor and the elevator floor can be calculated. When the height difference is obtained, the elevator leveling is completed, so that the maintenance personnel can adjust the elevator according to the height difference so that the elevator can operate safely. Since two laser devices 200 are provided in this embodiment, two laser images are obtained based on the two laser devices 200, and then two laser line segments are obtained. Then, analysis is performed based on the two laser line segments, and two different height differences can be calculated based on two different elevator lasers and stair lasers. The height difference can be determined more accurately through two measurements. Of course, this embodiment can also control the time interval for obtaining laser images, such as setting the laser images to be obtained every other week, so that multiple measurements can be achieved, and the measurement accuracy can be improved, so as to know the use status of the elevator in a timely manner.

[0068] In summary, this embodiment first obtains the original image and laser image of the area to be measured, and the position to be measured includes the elevator floor, the floor floor, and the gap area between the elevator floor and the floor floor; according to the original image and the laser image, the laser line segment is determined, and the floor laser line segment and the elevator laser line segment are determined according to the laser line segment; according to the floor laser line segment and the elevator laser line segment, the height difference between the floor floor and the elevator floor is determined. The present invention can realize automatic leveling of the elevator, and the measurement result is more accurate. Moreover, the leveling of the present invention is not affected by time or human factors, and can be leveled in real time, which helps to realize the monitoring of the elevator status throughout its life cycle.
