3D机器视觉检测技术优势明显，市场应用空间广阔!

　　目前机器视觉技术主要是以2D图像分析和识别为主，随着工业自动化的不断升级，以及传感器等硬件设备和AI算法等技术的不断发展，机器视觉实现了从二维向三维的跨越式升级，3D机器视觉技术开始走上工业应用舞台。
　　At present, machine vision technology mainly focuses on 2D image analysis and recognition. With the continuous upgrading of industrial automation, as well as the continuous development of hardware devices such as sensors and AI algorithms, machine vision has achieved a leapfrog upgrade from 2D to 3D, and 3D machine vision technology has begun to enter the industrial application arena.
　　中国作为“世界工厂”，必定要从初级的生产制造向尖端制造转变，发展尖端制造，精密制造业必不可少。精密制造业对于精度要求也推动3D机器视觉在工业应用场景的推广。此外，劳动力人口红利的消失以及当前疫情的反复也在不断推动制造业以机器换人工，多种趋势表明机器替代势在必行，且技术不断朝着精密化、智能化方向发展。
　　As a "world factory", China must change from primary production and manufacturing to cutting-edge manufacturing. Precision manufacturing is essential to develop cutting-edge manufacturing. The precision requirements of precision manufacturing industry also promote the promotion of 3D machine vision in industrial application scenarios. In addition, the disappearance of the labor force demographic dividend and the recurrence of the current epidemic are also promoting the manufacturing industry to replace labor with machines. Various trends indicate that machine replacement is imperative, and technology is constantly developing in the direction of precision and intelligence.

　　3D机器视觉在技术发展以及市场需求的“双动力”下应运而生。3D机器视觉系统利用光学技术模拟人类视觉系统，具有精确坐标的三维点云，能够定位目标物体的高精度三维数字化模型。其突破了2D视觉受光源变化、依赖目标对象表面上的对比、无法处理高度信息等限制，为工业拆码垛、自动分拣等“痛点型”应用场景提供了专业的技术支持。
　　3D machine vision came into being under the "dual power" of technological development and market demand. The 3D machine vision system uses optical technology to simulate the human vision system. The 3D point cloud with precise coordinates can locate the high-precision 3D digital model of the target object. It breaks through the limitations of 2D vision, such as light source changes, dependence on the contrast on the surface of the target object, and inability to process height information, and provides professional technical support for industrial destacking, automatic sorting and other "pain point" application scenarios.
　　其主要工作原理为：红外激光发射器发射出近红外光，经过物体的反射后，图案被红外图像传感器（IR CIS）所接收，经过算法计算出物体所处的位置（Z轴）；而后可见光图像传感器采集二维平面（X与Y轴）的物体信息；两颗图像传感器的信息汇总至专用的图像处理芯片，从而得到三维数据，最终实现平面“视界”到立体“视界”的拓展。
　　Its main working principle is: the infrared laser transmitter emits near-infrared light, after the reflection of the object, the pattern is received by the infrared image sensor (IR CIS), and the position of the object (Z-axis) is calculated through the algorithm; Then the visible light image sensor collects the object information in the two-dimensional plane (X and Y axes); The information of the two image sensors is summarized to a special image processing chip to obtain three-dimensional data, and finally realize the expansion from the plane "horizon" to the three-dimensional "horizon".
　　3D视觉技术可以获取物体的深度信息，再通过算法的精准定位，让机器在生产过程中对物料的使用和把控更加精准，几乎可以用于工业生产的任何场景，如拆垛、分拣、检测、测量、避障等。在行业应用需求的推动下，3D机器视觉技术已经实现从单场景应用发展到为全产线生产赋能。
　　3D vision technology can obtain the depth information of objects, and then through the accurate positioning of algorithms, the machine can use and control materials more accurately in the production process. It can be used in almost any scene of industrial production, such as destacking, sorting, detection, measurement, obstacle avoidance, etc. Driven by the industrial application demand, 3D machine vision technology has developed from single scene application to full production line production empowerment.
　　与3D视觉技术火热的发展态势相反，其市场应用规模在现阶段并未追赶上2D。2021年，2D视觉市场规模约为107.8亿元，3D视觉市场约为11.51亿元，但2021年全年3D视觉市场增速超过 100%。可以说，2D机器视觉技术是当下主流，而3D机器视觉技术是未来趋势。
　　Contrary to the hot development trend of 3D vision technology, its market application scale does not catch up with 2D at this stage. In 2021, the 2D vision market will be about 10.78 billion yuan, and the 3D vision market will be about 1.151 billion yuan, but the annual growth rate of the 3D vision market in 2021 will exceed 100%. It can be said that 2D machine vision technology is the current mainstream, while 3D machine vision technology is the future trend.
　　工业物流场景具有场景差异大，品类丰富且新增频繁等特性，SKU种类繁多等痛点长时间导致机器视觉方案批量落地难度大。3D视觉技术加持下，针对工业物流行业的应用痛点，红宝自动化针对性的制定出“AI+3D+工业机器人”的解决方案。
　　The industrial logistics scene has the characteristics of large scene differences, rich categories and frequent additions. The pain points such as the wide variety of SKUs for a long time make it difficult to implement machine vision solutions in batches. With the help of 3D vision technology, Hongbao Automation has developed a "AI+3D+industrial robot" solution targeted at the application pain points of the industrial logistics industry.
　　首先利用AI算法模型快速完成应用搭建，而后通过红外图像传感器接收周转箱反射回的近红外光，经过算法计算出周转箱所处的位置，最后由工业机械臂完成对周转箱的抓取、拆垛。整个过程，工业机器人在180秒内同步完成视觉测距、定位、探测以及路线规划，实现精准拆垛。在一些复杂垛型中，搭载了3D视觉技术的工业机器人也能准确识别物体的摆放姿态（如紧密贴合、随意摆放、堆叠等），精准分割周转箱目标。
　　First, use the AI algorithm model to quickly complete the application building, then receive the near-infrared light reflected by the turnover box through the infrared image sensor, calculate the position of the turnover box through the algorithm, and finally use the industrial mechanical arm to grab and unpack the turnover box. In the whole process, the industrial robot synchronously completes the visual ranging, positioning, detection and route planning within 180 seconds to achieve accurate destacking. In some complex stacks, industrial robots equipped with 3D vision technology can also accurately identify the placement posture of objects (such as close fitting, random placement, stacking, etc.), and accurately segment turnover box targets.
