Embodiment 1

[0043] figure 1 It is a schematic structural diagram of a construction site scene image acquisition system according to Embodiment 1 of the present invention. Such as figure 1 As shown, the construction site scene image acquisition system may include: a camera unit 100, which is arranged on the boom of the construction machinery and is located above the cloth area of ​​the construction machinery in the working state, and is configured to adapt to different movement states of the boom While capturing multiple single images of the construction site area where the construction machinery is located; the boom detection unit 200 is configured to detect multiple rotation angles or multiple boom posture information corresponding to the different boom motion states, wherein The attitude information of the jib includes the corresponding rotation angle of the jib when it moves; and an image processing unit 300 communicating with the camera unit 100 and the jib detection unit 200 . Furt...

Embodiment 2

[0075] Figure 4 It is a schematic structural diagram of a construction site object recognition system according to Embodiment 2 of the present invention. Such as Figure 4 As shown, the construction site object recognition system may include: the construction site scene image acquisition system described in Embodiment 1 or Embodiment 2, configured to obtain a construction site scene image representing the construction site area where the construction machinery is located; the coordinate fusion unit 500 is It is configured to associate any pixel point in the construction site scene image with a construction machine coordinate system, so that any pixel point in the construction site scene image can correspond to a certain position on the construction site plane in the construction machine coordinate system; And the object identification unit 600 is configured to identify the construction site according to the position of each pixel point in the construction site scene image an...

Embodiment 3

[0099] Embodiment 3 of the present invention provides a construction machine, which includes the construction site scene image acquisition system described in Embodiment 1 or Embodiment 2 above, or includes the construction site object recognition system described in Embodiment 2 above.

[0100] Wherein, the construction machinery is, for example, a pump truck or a crane.

[0101] The construction machinery of the third embodiment uses the image stitching technology to obtain construction site scene images for the first time, and performs image correction through the rotation angle to enhance the stitching effect, which is conducive to forming high-quality stitched images, and further identifying construction site objects to expand more engineering applications.

[0102] For more implementation details and effects of the construction machine of the third embodiment, reference may be made to the above-mentioned first to second embodiments, which will not be repeated here.

Abstract

The invention relates to the field of engineering machinery, and discloses a construction site scene image acquisition system and method and a construction site object identification system and method. The construction site scene image acquisition system comprises: a camera shooting unit which is arranged on a cantilever crane of engineering machinery and is used for capturing a plurality of single images of a construction site area by adapting to different cantilever crane motion states; a cantilever crane detection unit which is used for detecting a plurality of rotation angles or a plurality of pieces of cantilever crane attitude information corresponding to different cantilever crane motion states, including the corresponding rotation angles when the cantilever crane moves; and an image processing unit which is used for carrying out angle correction on the corresponding single image according to the rotation angle and splicing a plurality of single images subjected to angle correction to form a construction site scene image representing the construction site area. According to the invention, the camera shooting unit is arranged on the arm support, so that image acquisition at a top view angle is easy to achieve, mutual shielding among objects on a construction site is avoided, and an image correction scheme based on a rotation angle is provided, so that high-quality images can be formed.

Description

technical field [0001] The present invention relates to the field of construction machinery, in particular to a system and method for acquiring construction site scene images and recognizing construction site objects. Background technique [0002] At present, obtaining construction site scene images has great practical value for the operation control of construction machinery in the site. In the prior art, there are mainly the following two schemes for acquiring construction site scene images: [0003] 1) The "ultra-elevation" camera imaging method (that is, the remote sensing method) is used to capture the scene image of the construction site, that is, the drone, hot air balloon, etc. are used to carry the camera, and the construction site is photographed from a height far exceeding the size of the construction machinery and the construction site. Get the scene. This is the most common method, but in actual application, not only the cost is high, but also there is a contr...
