“…The development of this technology not only improves measurement efficiency but also reduces interference to the surface of the workpiece, meeting the growing demand of modern industry for product quality and precision. However, in this process, the specular reflection problem [1] seriously reduces the accuracy of 3D measurement. Therefore, dealing with the specular reflection problem is a crucial consideration in structured light 3D measurement applications.…”

Optical 3D detection technology has a wide range of applications in industrial detection, agricultural production, and so on. Its advantages are non-contact, efficiency, and high precision. However, the specular reflection problem affects model coverage and measurement accuracy. An optimization algorithm for calculating the number and pose of sensors has been proposed to address this issue. First, the specular reflection problem is viewed as a multi-sensor position search problem. Then, an optimization algorithm is used to find the optimal number and bit positions of sensors to avoid specular reflection. The experiment shows that the optimization results of this algorithm can cover the area to be measured with the least number of sensor combinations while avoiding the influence of specular reflection.
