视觉定位技术是GNSS接收器开发的主要突破
这GNSS Receiver has evolved over the years. Through continuous product improvements, a highly integrated RTK receiver with inertial navigation and multi-constellation is nothing new. While RTK receiver is constantly being improved in terms of better results, mapping users still face many bottleneck scenarios where traditional ways are not easy to complete.
就目前而言，典型的GNSS接收器需要在开放环境中搜索卫星信号，以实现高精度测量。只有在GNSS RTK接收器可以访问开放天空并且杆尖实际接触点时，才能测量点的位置。否则，需要执行许多不同的辅助方法来测量确切的位置。通过许多细节，危险区域的目标以及环境遮挡过多的目标测量目标都是传统的GNS接收器尚未解决的巨大挑战。突破测量场景的局限性是开发创新GNSS接收器技术的关键研究重点。
New Technology Application
In an era where computer technology is so advanced and sensing technologies such as AR and UAV have gained widespread attention in society, especially, in the surveying and mapping industry, staying in the high-tech technology industry, Hi-Target continues to focus on emerging technologies that can empower high-precision measurement instruments. The GNSS Receiver with visual positioning technology was born.VRTKadopts the technology of UAV oblique photogrammetry and can achieve a full range of image processing, but compared with the UAV image measurement, visual RTK surveying can be operated at ground level with more ground details that can not be measured by the UAV. It is free from height restrictions but maintains accuracy and more details, realizing fine management.

New Product Arrives
您的想法是VRTKwith cutting-edge technology. Such a Hi-Target pocket-sized vRTK Receiver is a ground-breaking product that has been prepared carefully over many years. Accordingly, it is a high-precision measuring solution that realizes long distance non-direct contact and guarantees the safety of personnel and data accuracy.
Making Surveying Easier and Easier
Keeping the Sword Sharp Comes from Sharpening It
作为行业领导者，Hi-Target长期以来一直意识到用户体验的缺点。2016年，Hi-Target开始研究Visual RTK，并推出了第一个Visual GNSS接收器组合类型产品，包括接收器 +专业级相机 +平板电脑，用于3D图像处理。尽管该产品可以提供更好的结果，但复杂的组合表格并未被广泛接受。随着成功的推出V200 RTK接收器, we have miniaturized the RTK Receiver and added new image positioning technology. We also upgrade the hardware to create a multi-functional product designed from the customer's perspective. There is no doubt that it is time to open up a whole new world of non-contact measurement.
这Enriched Performance of vRTK
Multi-Protocol Built-In Radio
VRTKhas all the premium features of the V200 with the extra value of visual positioning technology. Moreover, it includes a new motherboard and an upgraded IMU model. Like any other GNSS sensor from Hi-Target,VRTK可以使用所有GNSS校正服务中的RTK校正。随着摄像机的添加VRTKreceiver still retains a pocket size. It only weighs 970g including a built-in 6900mAh battery. With continuously operating for 15 hours in rover mode, it satisfies the user's needs for full-day work. The built-in Hi-Target multi-protocol UHF modem is capable of transmitting and receiving multiple brands of RTK radio power conditioning with a typical operating range of 7km.
Strong Signal and High-Quality Data
新一代的GNSS引擎支持Beidou-3卫星的新频率B1C，B2A和B2B RTK解码。引入多频反判断技术和多步自适应过滤技术具有强信号，高质量数据，快速固定和高精度。
高级IMU模块
这VRTK采用了升级的9轴IMU模块，该模块具有用于倾斜调查的自动安装。用户很容易将其捡起并到达目标点进行倾斜调查。理想情况下，误差在60°倾斜度内小于2.5厘米。它大大提高了工作的效率。在倾斜调查之前，用户不再需要采取繁琐的准备步骤。
VRTK: Innovative Integration of Vision and Surveying
VRTK适用于非接触式测量变化ety of hazardous and complex environments. High-quality sensors ensure the stability of the receiver's accuracy in working status. By combining imagery with high-precision positioning equipment, users will benefit from the convenience of visual positioning technology, which allows them to obtain the location of the target simply with a touch of finger from a distance. The image data with location information can unlock more usage scenarios so that measurements will no longer encounter barriers. What you see is what you get.
Image Survey
Firstly, the new image survey function achieves non-contact measurement. Consequently, it greatly enhances the available range of GNSS and efficient, safe operation. Based on Android's high-performance image processing technology, the 5MP camera for the rear view combined with the controller can obtain precise coordinates in real time, at distances of 2-15 meters, with an accuracy of 2-4 cm.
What Are the Working Scenarios?
这image survey ofVRTKis available in the following scenarios where traditional GNSS receivers could not work. It allows for better measurement results.
- Scenes contain a lot of details.
- 偏远地区,如沙漠、悬崖、峡谷等c.
- 危险的场景，例如繁忙的道路，事故场景或危险区域（例如，狗攻击和危险公用事业的风险。）
- 具有GNSS的区域信号障碍物，例如屋顶和树木。
- Target points on building facades such as the corners of windows and the roofs.
- 在不重新审视网站的情况下测量其他要点。
- 通过测量对城市进行3D建模。
- Integrated surveying projects for premises.
主要是，对于国内局势，关于地astral测量的官方项目是VRTKto play its advantages. With the promotion of our government's integrated rural premises measurement project, carrying out integrated rural premises measurement is an important element of real estate surveying and mapping at this stage. UAV oblique photogrammetry technology provides a new means and method for integrated rural premises measurement, which has the advantages of high efficiency, low field workload, and low cost compared with traditional cadastral and property measurement methods.
AR Live-View Stakeout
Besides, the AR live-view stakeout is a new upgrade of the AR stakeout function in the Hi-survey software. In the past, the AR stakeout would merely show 3D animation for the direction and distance after approaching the target. However, when the surveyor approaches the stakeout point holding the latestVRTKwith the AR stakeout function, the screen of the controller will change to the view from the camera at the bottom of theVRTK。下面的2MP摄像头可实现AR视图，精度为2厘米。它节省了时间和精力，以达到出色点。
3.3与3D建模软件的兼容性
从VRTKare compatible with third-party data processing software. It meets the needs of different industry applications. Moreover,VRTKis newly compatible with mainstream modeling software, making 3D modeling as simple as possible. At the same time, the image data byVRTK将是弥补航空图像测量无法衡量特征细节的绝佳工具。结合来自无人机的图像数据，VRTK，3D软件中的整个效果将更加完整和详细，这对于工程用户来说绝对是个好消息。
衡量您在方便时看到的东西
最后但并非最不重要的一点是，作为一种创新且备受期待的产品，VRTKwill be launched with Hi-Target's new large screen controller iHand55, both of which are extremely light and portable while providing a long battery life to ensure that users can easily and efficiently complete surveying tasks in fieldwork.
Hi-Survey will also be the perfect partner for surveyors working outdoors withVRTK。这new Hi-Survey software is to optimize the efficiency of the image survey and AR live-view stakeout. It allows users to use them very smoothly. In addition, the new CAD drawing function supports user-defined CAD drawing and easier operation for faster import and precise capture.
发射VRTKis a new milestone in the development of GNSS receivers, which not only breaks through the limitations but also greatly improves efficiency and accuracy. It combines several innovative technologies in a pocket-sized receiver, fully reflecting the highest degree of Hi-Target's GNSS receiver. Hi-Target focuses on creating more user-friendly products in the clients’ best interest. Furthermore,the team keeps developing GNSS Receiver as the best tool for surveying work.
