"Eyes" in Urban Renewal: How M360 LiDAR Solves Survey Challenges

Recently, while working on several urban renewal projects across different cities, we encountered a very real challenge: decades-old blueprints just don't match the current reality. Back in the day, we used measuring tapes to take measurements point by point, which was tiring and prone to missing measurements. Once you missed critical data, you had to redo the work—a problem that became particularly evident during last year's urban renewal project in a certain city.

The urban renewal policy required comprehensive renovation of old districts, but those old planning maps simply couldn't keep up with actual changes. Traditional measuring tape methods were too inefficient, and the precision just wasn't up to standard. At that time, we started wondering if there was any technology that could quickly and accurately collect 3D data from these old districts. We finally found the M360 LiDAR, and this device actually solved many practical problems.

From "Manpower-Intensive" to "Single-Person Operations"

For similar surveying projects in the past, we typically needed 3 people spending 7 days collecting data, plus another person taking 7 days for modeling. The labor costs alone were high, and the timeline was too long.

Now, with M360 LiDAR paired with handheld scanners, the situation is completely different:

  • 1 person can complete data collection in 1 day
  • Modeling time is also compressed to 1 day
  • Labor costs are directly reduced by 70%

The efficiency improvement is so significant mainly because M360 has several features that are particularly suitable for this type of surveying:

First, 5cm near-field blind spot. In urban renewal projects, we often encounter various low obstacles like steps, thresholds, and decorative elements. If the blind spot is too large, these obstacles can't be detected. M360 has only a 5cm blind spot, even small obstacles close to the ground can be captured.

Second, 70-degree vertical field of view. That's 11 degrees more than many radars, providing broader scanning coverage. In the complex environment of old districts, you can scan more data in one go without repeatedly adjusting angles.

Third, IP67 protection rating. Urban renewal often takes place outdoors, where dust and rain are common. IP67 protection means completely dust-proof and short-term waterproof, making the device stable in such environments.

Fourth, very low power consumption. M360 consumes less than 4.5W, about 30% more energy-efficient than many similar products. Handheld devices powered by batteries have longer battery life, allowing field personnel to work continuously for longer periods.

On-site Operations Are Truly Convenient

The handheld scanner we use integrates M360 LiDAR, visible light camera, and RTK module into one unit. It's very lightweight, allowing single-person operation for extended periods. Unlike traditional mechanical LiDAR that weighs nearly a kilogram, plus other components, making the entire device quite bulky and cumbersome to operate.

The most intuitive feeling during operation is not having to frequently adjust angles. M360 uses a 20-degree tilt-down installation, simultaneously covering the ground, front, and ceiling. In the field, survey personnel don't need to deliberately adjust the device angle to collect data from all directions at once.

This is particularly useful in actual operations. Traditional equipment requires repeated angle adjustments to collect complete data, often requiring multiple measurements at a single point. Now with M360, one scan can basically cover the required area, significantly improving efficiency.

Data Quality Is Quite Good

The collected point cloud data achieves centimeter-level precision, which is sufficient for urban renewal projects. Based on this data, we can create accurate 3D models for subsequent design and planning work.

In actual projects, we used these point cloud models to redesign and plan the districts. Compared to traditional 2D drawings, 3D models can more intuitively display spatial relationships, helping designers make better decisions.

This is especially valuable when dealing with protective renovation of historic buildings. We can precisely measure various parts of the building to ensure that the renovation process preserves the original features to the greatest extent possible.

Cost Control Is Also Well-Managed

Compared to traditional mechanical LiDAR that cost tens of thousands, M360 has a clear price advantage. Although I didn't ask about the specific price, I heard it offers great value for money. This is very important for large-scale urban renewal projects—good cost control allows the project to continue and expand.

Another cost advantage is the significant reduction in labor costs. From the previous "manpower-intensive" approach to now "single-person operations," labor costs have been reduced by at least 70%. For local governments with limited budgets, this is truly a major attraction.

Practical Experience in Applications

During several months of actual use, we found that M360 performs particularly well in several aspects:

First, good performance in rainy and foggy weather. Although M360 mainly relies on single-echo operation, in the environment of old districts, the impact of rain and fog is relatively small. If special requirements arise, there's also a dual-echo version available that can better penetrate raindrops to see obstacles behind them.

Second, very accurate time synchronization. M360 has built-in IMU, supports PTP v2 and GPS time synchronization, and can accurately synchronize with point cloud data. In multi-sensor fusion applications, this feature is crucial.

Third, wide power supply range. The 12-32V power supply range is wider than many products, adapting to different vehicle-mounted power solutions. In handheld devices, this wide voltage supply means better compatibility.

Summary

Through the practice of these projects, I feel that M360 LiDAR applications in urban renewal are indeed very valuable:

  • Significant efficiency improvement: from "manpower-intensive" to "single-person operations," time reduced by 70%
  • Reliable data quality: centimeter-level precision meets renovation requirements
  • Good equipment portability: lightweight, easy single-person operation
  • Strong environmental adaptability: IP67 protection, stable operation in outdoor environments
  • Clear cost advantage: high value for money, low labor costs

Especially in the complex environment of old districts, M360's near-field blind spot, wide field of view, and low power consumption characteristics have truly solved many pain points of traditional surveying methods. If there are similar projects in the future, we will continue to choose M360.
