Embodiment 1

[0046] figure 1 It is a schematic flowchart of a gesture recognition method for construction machinery boom equipment provided in Embodiment 1 of the present invention, wherein the construction machinery boom equipment includes boom pump trucks, lifting machinery with folding arms, and folding arm firefighting equipment. car etc. like figure 1 As shown, the gesture recognition method may include the following steps:

[0047] Step S110, acquiring an image of the boom-like equipment of the engineering machinery.

[0048] Wherein, after acquiring the image of the engineering manipulator arm joints, since there are interference signals when acquiring the image, it is necessary to preprocess the acquired image, for example, conventional image processing such as grayscale processing and denoising processing technology, so that the processed image is clearer, and it is convenient to determine the posture of the arm joint later.

[0049] Step S120, according to the preset model corr...

Embodiment 2

[0066] Before the first embodiment above obtains the image of the construction machinery jib equipment, the solution of the second embodiment of the present invention can be combined with the inclination sensor to jointly determine the attitude of the boom section. Figure 4 It is a schematic flowchart of a posture recognition method for construction machinery boom equipment provided in Embodiment 2 of the present invention. like Figure 4 As shown, the method includes the following steps:

[0067] Step S410, obtaining the reading data of the inclination sensor between the arm segments in the arm frame equipment of the construction machinery;

[0068] Step S420, judging whether the read data of all the inclination sensors has been obtained, if yes, continue to execute step S410, otherwise execute step S430;

[0069] Step S430, determining that the inclination sensor for which the read data has not been obtained is faulty, and notifying the acquisition of the image of the con...

Embodiment 3

[0076] Figure 5 It is a schematic structural diagram of a posture recognition device for construction machinery jib equipment provided in Embodiment 3 of the present invention. The posture recognition device is based on the same inventive idea as the posture recognition method in Embodiment 1. like Figure 5 As shown, the gesture recognition device may include: a storage module 10 for storing computer-executable instructions; and a control module 20 for executing the computer-executable instructions to perform the following operations:

[0077] Obtaining the image of the boom-type equipment of the construction machinery;

[0078] According to the preset model corresponding to the boom-type equipment of the construction machinery, identify the vehicle image and the jib image corresponding to the boom-type equipment of the construction machinery from the image;

[0079] Obtaining the image scaling ratio according to the vehicle imaging size and the actual vehicle size in the ...

Abstract

The invention relates to the field of engineering machinery, and discloses a posture recognition method and device for engineering machinery cantilever crane type equipment and engineering machinery.The posture recognition method comprises the steps: acquiring an image of the engineering mechanical arm frame type equipment; according to a preset model corresponding to the engineering mechanical arm frame type equipment, identifying a vehicle image and an arm section image corresponding to the engineering mechanical arm frame type equipment from the images; obtaining an image scaling ratio according to the vehicle imaging size and the vehicle actual size in the vehicle image; and determining the arm section and the arm section posture in the arm section image according to the actual lengthof the arm section, the number of the arm sections and the image scaling ratio in the engineering mechanical arm frame equipment. According to the invention, through the image recognition technology,the recognition of the posture of the arm section in the engineering mechanical arm frame type equipment is realized, and compared with the mode of obtaining the posture of the arm section by depending on various sensors in the prior art, the method reduces the cost, the method can better adapt to a complex engineering environment, and the method improves the recognition accuracy.

Description

technical field [0001] The present invention relates to the field of engineering machinery, in particular to a posture recognition method and device for engineering machinery boom equipment and the engineering machinery. Background technique [0002] In the prior art, the direct acquisition method and the indirect conversion method are generally used when identifying the boom attitude of construction machinery boom equipment. Among them, the direct acquisition method is to directly acquire the horizontal inclination angle of the boom section through the inclination sensor to realize the attitude perception of the boom. The indirect conversion method is to obtain the displacement change value of each arm section of the cylinder through the magnetostrictive displacement sensor or the wire sensor of the cylinder, and convert it into an angle value jointly with the structural parameters. [0003] However, for the direct acquisition method, an inclination sensor needs to be arra...
