Problems solved by technology

[0004] Aiming at the problems existing in the above-mentioned background technology, the present invention proposes a high-precision 3D reconstruction system for indoor plastering robots based on LCOS, to solve the problem that traditional building plastering robots use lasers to measure distances during work, and the entire wall obtained The surface distance information has poor real-time performance and low precision, which leads to the problem that the unevenness of the plastered wall surface is difficult to reach the industrial level and the cost is high

Embodiment Construction

[0039] In order to make the objects, technical solutions, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0040] figure 2 A basic configuration of the system provided by the embodiment of the present invention. Such as figure 2 As shown, including the PC, LCOS drive control module, a two-point camera, and LCOS projecting devices, plastering machine, and plasterial motion control modules. The PC is primarily used to transmit the control command to the LCOS drive control module, receive images captured by binary cameras; and use the received image information to perform three-dimensional reconstruction, and then provide the reconstructed 3D information to the plaster master module. The LCOS drive module is an LCOS development board for embedded pattern programs; the LCOS control signal provided by the PC is supplied, and the embedded pattern is supplied to the device module by t...

Abstract

The invention belongs to the field of building plastering robots and computer data processing, and particularly relates to an indoor plastering robot high-precision three-dimensional reconstruction system based on LCOS (reflective projection display). Patterns written in advance are projected on a wall surface needing plastering through an LCOS projection technology, wall surface projection is captured through a binocular camera, then acquired pictures are subjected to data processing through a PC, and three-dimensional information reconstruction of the wall surface needing plastering is completed; the PC is connected with a robot master control module through a TCP to send data to the plastering robot, and the plastering robot master control module controls a plastering machine to be adjusted to a designated operation position for plastering. The active three-dimensional reconstruction projection technology and the building plastering robot are combined, and the problems that the precision of laser in the field of building robots is not enough, and the effect is not good are solved.

Description

Technical field [0001] The present invention belongs to the field of building plastering robots and computer data processing, which involves a high-precision three-precision three-dimensional reconstruction system based on LCOS (reflective projection display). Background technique [0002] With the development of computer technology, computer equipment has been deeply involved in various aspects in social life; using computer for visual and digital image processing technology, it is increasingly mature, in the field of various tips, showing the front. The purpose of computer vision is to study the intelligence of computers through the analysis of related theories and technologies, so that they achieve "see" similar to human eyes. Specifically, computer vision technology uses a camera and computer replacement to make the computer owns the segmentation, classification, identification, tracking, discrimination of decision making of human eyes. The computer vision system refers to a ...
