Applied Research of the UAV Illumination Measurement System in Sports Stadiums

Round 1

Reviewer 1 Report

The authors attempted to build an illumination measurement system using UAV. The work is interesting and has some practical applications. However, the paper is written more like a report rather than a research manuscript. It essentially lacks the major components of a research paper such as related work, research gap, proposed methodology and contributions of the proposed work and moreover the conclusion. Hence, I would suggest the authors address the following concern and resubmit the paper.

Comments

1.       The title of the articles needs to be more precise and the word  “research” in the title seems a bit general.

2.       Authors are suggested to provide some background applications of UAV  in various domains such as [1] [2] to highlight the potential of UAV technology.

a.       https://www.mdpi.com/2072-4292/15/9/2450

b.       https://www.hindawi.com/journals/jmath/2020/4308756/

3.       More elaboration or discussion of the research problem is required, providing the motivation, existing research gap and the proposed solution.

4.       Few abbreviations are used without their full forms. For example, LOF.

5.       The English needs improvement in the paper. A professional English proofreader may help.

6.       Authors did not present the real samples of illuminance data, why?

7.       More test cases are needed for the further validation of the system.

8.       The paper has no conclusion section, why? It’s surprising.

9.       Overall, the manuscript is not able to tell a complete story and convince the reader. More effort is needed.

Reviewer 2 Report

This paper focuses on the use of UAVs as a platform for measuring levels of luminosity in sports halls. This rather simple and application-oriented task hides a relatively interesting application of the UAV as a sensor. From a methodological point of view, the basis of the proposed solution is the use of a small drone to position the measurement sensor in a three-dimensional space, which allows the reconstruction of a three-dimensional model of illumination in the environment. Solving this problem without using an automated platform presents obvious challenges. The accuracy declared in the paper has to be considered satisfactory. The methodology for positioning the platform in enclosed spaces is described separately and in due detail in the paper, as well as the refinement of the results in the case of outliers. It can be assumed that the proposed methodology can be easily scaled up and extended to other applications. 
The abstract of the paper fully captures the essence of the research and the results achieved. 
The paper is written in a well readable language and is well structured. The presentation is logical, consistent, and a reasonable criticism of the method and the results obtained is given. The work is satisfactorily illustrated and provided with a small, but rather relevant reference. 
The paper has an applicative purpose, fully corresponds to the scope of the journal, and can be published in its current form.

Reviewer 3 Report

This manuscript reviews “Research for applications of the UAV illumination measurement system in sports stadiums. The study has novelty and innovative steps to measure lighting in sports venues. I recommend that this article be published in the current journal.

 But the authors must correct the following before publishing the article.

 

-          In line 21, the full sentence of RMS should be stated before it.

-          In line 29 to 30, Please state some standard lighting codes for sports stadiums.

-          At the end of line 32 and 34, reference should be placed.

-          In line 29 to 30, the meaning of two terms “real time, and at the same time,” are the same, the second term should be deleted.

-          In line 74 to 75, “BH750FVI” to be expressed in more detail. For example, model, manufacturer

-          In line 75, “combined with the above factors”? It would be better to repeat it in more detail.

-          In line 77, “STM32F103RCT6” to be expressed in more detail. For example, model, manufacturer

-          In line 109, “(BH1750), (ESP8266)” to be expressed in more detail. For example, model, manufacturer

-          In lines 148, 153 and 155, ()??What is the purpose of empty parenthesis?

-          In line 151, Event time ---- > event time change.

-          In line 236, which version of Dialux was used?

-          In lines 238 to 241, reference should be placed.

-          It is recommended that the details of the measurement location, and how to measure manually (Figure 10), was it measured at night or during the day? Did the natural light from the windows have an effect on the illuminance in measurement?

-          In general, more details of the measured stadium should be stated, for example, the geographical location, these items can be stated in the first material and method.

-          In line 332, it is better to state their reflection coefficient in addition to the color of the floor and wall surfaces.

Round 2

Reviewer 1 Report

The authors addressed all of the concerns raised in the first review round. The paper now looks much better.
