Embodiment Construction

[0038] Such as figure 1 As shown, a method for identifying the depth of a foundation pit based on multiple cameras includes the following steps:

[0039] S201: Collect and obtain the paired dual-camera data, including camera position parameters, including the focal length f of the camera and the reference distance b between the dual-cameras, and perform camera video and dual-camera calibration correction to ensure the image plane of the dual-camera coincide, making the subsequent depth estimation accurate;

[0040] S202: Preprocessing the acquired video data, including extracting key frames and frame image preprocessing, the goal is to extract frame images for depth estimation from the video data;

[0041] S203: Use the trained deep semantic Faster RCNN to segment the network, segment and obtain the part of the machine pit, and initially obtain the part of the depth of the machine pit that needs to be measured;

[0042] S204: Use the edge detection algorithm image processing...

Abstract

The invention discloses a method for identifying the depth of a foundation pit based on multiple cameras in the building field, and the method comprises the following steps: S201, collecting and obtaining paired dual-camera data, including position parameters of the cameras, videos of the cameras and calibration correction of the dual cameras; S202, preprocessing the acquired video data, wherein the preprocessing comprises key frame extraction and frame image preprocessing; S203, performing segmentation by using the trained deep semantic Faster RCNN segmentation network to obtain a foundation pit part. S204, obtaining the upper and lower edges of the foundation pit by using an edge detection algorithm image processing technology, and correcting the position of the part needing to be measured; S205, predicting the depth of a part needing to be measured by using a binocular camera imaging principle, and estimating the depth of the foundation pit. and S206, integrating the depth information of the foundation pit and the measured position information in the S204 and the S205, and visually feeding back the measured part and the estimated height.

Description

technical field [0001] The invention relates to the field of construction engineering, in particular to a method for identifying the depth of a foundation pit based on multiple cameras. Background technique [0002] At this stage, the identification of the depth of the foundation pit on the construction project site is mainly completed by visual inspection and matching measuring instruments, such as box rulers and tape measures. After the measurement is completed, the data is recorded again, and finally the identification of the depth of the foundation pit is achieved. In the identification process, the identification of the depth of the foundation pit is done manually, which increases the cost of the project. Of course, it is difficult to ensure the accuracy and real-time performance of the identification data. Contents of the invention [0003] The purpose of the present invention is to provide a method for automatically identifying the depth of the foundation pit and r...
