The detection technology of soft mattress construction is to ensure that the soft mattressis laid in accordance with the standards and confirm whether the construction quality achieves the desired effect.To achieve the intelligent control of the soft mattress construction,we construct the overall architecture of the mattress construction management system,analyze the key technologies of the construction detection,i.e.the image stitching technology and the lap width of image recognition technology,and propose the design requirements and schemes of the system’s hardware,software and data acquisition systems.
