Shulou(Shulou.com)05/31 Report--

Data service company Qizhi Technology recently completed 10 million yuan Pre-A round financing, the investor is Midea holding. It is reported that this round of financing funds will be mainly used for the establishment of product research and development and delivery centers.

Optimistic about the commercial application of drones, Chen Junyu and Li Bingjun led a team to set up Qizhi Technology, and launched the drone cooperative combat platform "Qizhi Mobile MeshKit" in 2016. This is an Internet of things software system and data service platform based on UAV. In 2018, the team will determine the direction in the field of real estate construction engineering, with the first subdivision application being earthwork survey.

Founder and CEO Chen Junyu introduced to 36Kr that land surveying and mapping is an important step in the process of construction. Accurate measurement can help developers and builders to calculate and predict earthwork transport volume more accurately, thus guiding the adjustment of design and cost budget. However, the traditional measurement mode has some shortcomings, such as long collection period, insufficient data collection, difficult re-inspection, inaccurate calculation and so on.

Chen Junyu believes that with the increase of labor costs and the intensification of competition, real estate digital upgrading is an inevitable trend. At the same time, the development and industrial application conditions of UAV are becoming more and more mature, but how to effectively combine UAV application with engineering management application scenario and link it with traditional engineering work is still a pain point in the industry.

To solve the above problems, Qizhi Technology provides high-precision earthwork survey solutions for real estate developers and engineering contractors based on UAV and "Qizhi Mobile MeshKit" platform, which can be divided into the following links:

In the process of collection, the operator performs three simple steps on the mobile terminal: voice intercom to confirm identity-select surveying and mapping scheme-select land parcel, UAV automatically plan the route and complete the flight action, and the information is synchronized directly to the PC desktop to prevent data from being artificially tampered with.

The desktop submits the UAV information to the MeshKit cloud for modeling, and the MeshKit cloud service can quickly generate a 3D real-world model from ordinary photos taken by the UAV, form point cloud data information, and then complete earthwork calculation.

Finally, the point cloud data can be directly imported into the design software, and designers can design multiple project budgets based on the measurement results.

The team cooperates with a number of Class A qualified units such as surveying and mapping, planning and design, architectural design and so on. And several handheld RTK devices and drones have been compared. Taking a project with an area of 200000 square meters as an example, it is found that the manual RTK survey takes 4-5 days and the cost is about 160yuan / mu. The automatic collection of UAV only takes 30 minutes and the cost is 8 yuan per mu.

In the data comparison of multiple checkpoints, the plane and elevation deviations of the two schemes are less than 5 cm. Compared with the overall earthwork transportation calculation results, the difference between the two schemes is less than 2%. However, the UAV can collect more geomorphological feature points to express the terrain, which avoids the problem of missed and erroneous measurement in manual operation.

To sum up, using UAV to carry out earthwork survey can save the cost of early measurement and improve the efficiency of project development. Through more frequent and accurate real-time earthwork data, most of the systemic risks in the earthwork stage can be avoided and direct economic benefits can be brought to developers.

Aerial survey using drones is not the first creation of Qizhi technology, but the previous problem is complex process and high cost. Chen Junyu believes that the team's contribution is to highly standardize the low-cost and high-precision scheme of UAV earthwork survey:

In the collection scheme, according to different regions, topography, weather and flight restriction policies, "Qizhi Mobile mesh kit" App has adaptive algorithms to help users carry out route planning, data synchronization and task management.

Cloud modeling and contour topographic maps are automatic output and full-cycle standardized data, which can be applied to various departments of developers to help them improve their digital management level.

In addition, Qizhi Technology provides single attendance service.

The customers of Qizhi Technology include housing enterprises, construction engineering companies, design institutes and so on. Since its opening in October 2018, Chi Chi Technology has served dozens of real estate developers, including five Chinese real estate companies Top 10, some of which have reached group-level strategic cooperation, accumulating hundreds of service projects. Among them, Qizhi Technology has formally reached a strategic cooperation with Midea Real Estate. Qizhi Technology will undertake UAV earthwork surveys for more than 100 construction projects in China, and implement earthwork calculation and earthwork balance scheme design.

In the profit model, mainly SaaS fees, depending on the function, pricing varies from 100000 to 500000 per year. In addition, the team also provides a complete set of data collection and post-processing services, and charges for data services by way of payment. In 2019, the company expects revenue of between 30 million and 50 million yuan.

Chen Junyu said that the real estate construction industry is still very traditional, and from developers to upstream and downstream enterprises such as general contracting, architectural design, surveying and mapping, supervision and so on. The technology and technology of more than ten years ago are still in use. In recent years, major developers have been making up lessons for digitalization, and the application of drones is a good direction. Not only earthwork survey, Qizhi's future planning can also be extended to more follow-up links, through aerial data collection, processing, management and application, to help developers achieve digital transformation and upgrading.

As for the team, there are currently 50 people, headquartered in Hangzhou and offices in Shenzhen and Shunde. Founder and CEO Chen Junyu used to work for a large architectural design company and is a serial entrepreneur. In 2015, he jointly launched blank space, operating more than 20 million users; co-founder Li Bingjun is China's first iOS developer and drone flight control software developer, is the co-founder of Blank; partner Lu Ziyang is an angel investor in the field of TMT, an independent Hollywood filmmaker; and partner Liu Zhixuan works in Microsoft Dynamics365 Enterprise Services in Seattle.
