跨尺度空间全方位三维激光传感原理与关键技术研究

For the trans-scale, non-contact, automatic and omnidirectiol measurement in regular-size space and industrial applications, there are many deficiencies and application limitations for traditional measurement methods. On the basis of preliminary researches, novel solutions which cover the basic measurement platform architecture and principles of the 3D sensing measurement system (sensor) are proposed in the project. Reference to the three axes architecture of traditional equipments, a novel articulated laser sensing module is proposed combined with adaptive focusing technology of laser alignment, and the measurement principle is studied in detail. In the novel laser sensing module, there are also three axes, but they are non-orthogonal. The project will provide novel methods and effective techniques for the trans-scale, omnidirectiol, non-contact, automatic and accurate measurement of regular-scale objects in industrial applications, and promote the wide application and rapid development of the laser and photoelectric measurement techniques.
