Embodiment Construction

[0057] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0058] like figure 2 Shown is the image acquisition platform disclosed by the present invention. Including 1. Upper roller shaft, 2. Camera fixing link, 3. Cloth rolling roller shaft, 4. Cloth, 5. Cloth surface (edge ​​half cloth surface), 6. Industrial camera, 7. Pulling support. The cloth flows out from the upper roller 1 and enters the cloth rolling program through the lower roller. The camera fixing link 2 is parallel to the cloth 4, and perpendicular to the pulling support 7, and kept at 10-15 cm to ensure accurate focusing. The industrial camera 6 is fixed on the camera fixed connecting ro...

Abstract

The invention discloses a cloth surface positioning method in a complex environment, comprising: step 1, obtaining real-time cloth information of a loom through a built platform; step 2, adopting Gaussian filtering to eliminate the influence of noise; step 3, designing a new maximum The diffuse reflection chromaticity estimation formula eliminates the highlight problem caused by irregular lighting; step 4, extracts the edge information of the cloth, obtains the optical flow field, improves the instability of the optical flow, and proposes a new multi-frame optical flow fusion algorithm, combining edge information and optical flow The flow field information realizes the movement judgment and accurate positioning of the cloth surface. Obtain real-time images of loom cloth, and perform Gaussian filtering on the obtained images to eliminate noise caused by camera factors. This method removes overexposure and other problems in irregular environments, and at the same time improves the optical flow method combined with edge information to achieve motion judgment and accurate positioning of the cloth surface.

Description

technical field [0001] The invention loads an industrial camera module on a double-needle bed loom, and proposes a brand-new algorithm and platform for detecting cloth surface for intelligent production. A new algorithm for eliminating highlights is proposed to eliminate the overexposure problem in complex working environments, and at the same time, the improved optical flow algorithm combined with the edge algorithm is used to locate the cloth surface. Background technique [0002] With the development of technology, the scale of the textile industry has grown rapidly, and it has become an important economic pillar of my country's basic industry. With the advent of the Industry 4.0 era, the transformation and upgrading of traditional industries is imperative. Accurate positioning of the cloth surface can improve the operation accuracy of automation equipment, and can reduce the hardware cost of artificial intelligent detection equipment, thereby accelerating industrial tra...
