Autel Evo II VS 640T Dual drones produce various file types, leaving many new users confused about proper processing for thermal roof inspections. This article clarifies these file types and offers solutions for successful data processing.
Decoding Autel Evo File Types: .irg, .jpg, and .TIFF
The Autel Evo II VS 640T Dual generates three primary file types: .irg, .jpg, and .TIFF. Each serves a distinct purpose in thermal imaging.
.irg: This proprietary Autel file format contains raw thermal data. It holds the temperature information for each pixel, crucial for accurate analysis in specialized software. This format is often required for radiometric temperature measurement and analysis.
.jpg: This standard image format stores a visual representation of the thermal scene. While it lacks the detailed temperature data of the .irg file, it provides a readily viewable image for quick assessment and reporting. JPGs from thermal cameras often use a false-color palette to represent temperature variations.
.TIFF: Tagged Image File Format, known for its high quality and ability to store metadata. In the context of the Autel Evo, TIFFs may contain either visual or radiometric thermal data, depending on the camera settings. This versatility makes it suitable for both visual inspection and detailed analysis.
Processing Challenges and Solutions for Roof Inspections
Using software like Pix4Dmapper to process thermal imagery for roof inspections can be challenging for beginners. Understanding file compatibility and processing workflows is crucial for accurate results.
Common issues include incorrect file type selection, leading to poor quality reports and processing failures. Successfully processing Autel Evo thermal data for roof inspection requires selecting the appropriate file type (.irg or .TIFF containing radiometric data) and understanding the software’s specific requirements.
Overcoming these challenges requires a multi-pronged approach:
-
Mastering the Software: Invest time in learning Pix4Dmapper or similar software. Utilize available tutorials, documentation, and online resources to understand the workflow for thermal data processing.
-
Seeking Expert Guidance: Consider hiring a professional service for data processing and analysis. This provides expert insights and saves valuable time, especially for complex projects. Alternatively, seek mentorship from experienced thermographers.
-
Online Courses and Resources: Look for comprehensive online courses specifically focused on thermal image processing for roof inspections. These courses can provide structured learning and practical examples. YouTube can be a valuable source for introductory tutorials.
Conclusion
Successfully leveraging the Autel Evo for roof inspections hinges on understanding its various file types and mastering the subsequent processing workflow. By utilizing the right resources and strategies, even beginners can extract valuable insights from their thermal data. Proper file selection and processing are essential for accurate and actionable results in professional roof inspections.
