Four Thermal Cameras: Performance Analysis

By Piseo — Jul 2022

Comparison of architecture, sensor performance, image processing and tone mapping functions of four thermal cameras, based on measurement and independent analysis.

Key Features:

Analysis and comparison of the user functions of the camera and the development resources of the four thermal cameras
Analysis and overview of the image production processes and internal architectures
Set-up and objectives of the camera characterization
A comparative analysis of the bolometric sensor performance for raw images quality, responsivity, Noise Equivalent Temperature Difference, bad pixels, thermographic function and Residual Fixed Pattern Noise profile
Analysis and overview of the image processing and tone mapping functions
Our opinion of the four thermal cameras and their marketing positioning

Product objectives:

This report aims to provide a comprehensive comparison of independent analyses of the main features, performance, and imaging system architecture of four thermal cameras:

InfiRay T3S camera module
Teledyne FLIR BOSON 640 Pro camera
Seek Thermal S309P 12µm x 12µm QVGA module
InfiRay Micro III 384T camera module.

The analysis has been based on physical measurements, calculations, simulations and observations realized in PISÉO’s lab in comparison with data provided in the datasheet. This report incorporates four previous reports dedicated to each tested camera, which contain detailed performance analyses and explanations.

These reports help thermal imaging camera and module market actors to better understand the characteristics of such products, enabling better strategic decision making.

Context

Thanks to multiple drivers, the market for infra-red thermal imaging cameras and modules is expanding rapidly. It is expected to increase from $6,202M in 2021 to $8,761M in 2026. The estimated Compound Annual Growth Rate from 2021-2026 for thermal camera shipment volumes is 7.2%.

Defense application demand pulls the infra-red thermal imaging camera market. There is progressively more portable equipment for soldiers, such as thermal weapon sights and night vision goggles. ‘Smart city’ surveillance applications are also important. Thermal camera technology is increasingly adopted by integrators thanks to cost decreases. It is also boosted by the democratization of thermal imaging in industrial thermography. Finally, thermal imaging is becoming consumerized.

There are many products on the market. Users, integrators, and sensor manufacturers must discriminate between available products based on accurate and independent assessments of their performance and features.

PISÉO’s analysis

There are tens of thermal sensors and camera manufacturers including Teledyne FLIR, Seek Thermal, Raytheon Technologies, BAE Systems, Lynred, HikVision, InfiRay, i3system, GuideIR, Fluke, Safran and Testo. PISÉO has so far selected and analyzed four thermal camera modules, giving rise to four reports:

InfiRay T3S camera module,
Flir Boson 640 Pro camera,
Seek Thermal S309P 12µm x 12µm QVGA module
InfiRay Micro3 384T camera module.

Thanks to its own standard, PISÉO ran deep analyses of sensor performance and the embedded image processing algorithms of each camera.

These reports help thermal imaging camera and module market actors to better understand the characteristics of such products, enabling better strategic decision making.

The present report is a special one, reporting the most important performance test results and analyses done on these four cameras. It is an opportunity to make fair comparisons between product features and performance.

PISÉO’s finding

The FLIR Boson camera module is a reference in the infra-red thermal camera market. It is the product with the most accessible functionality, offering the most versatility to be used in a wide range of applications. The resulting image quality is good, the relatively low performance of the sensor being compensated by strong image processing algorithms.

The two InfiRay camera modules embed a well-performing sensor.

The InfiRay Micro III 384T delivers good quality images. However, the lack of documentation and supports suggests that this module is mainly dedicated to integration by InfiRay in its own products.

The InfiRay T3S camera module also provides good image quality. However, the versatility and integration possibilities are limited. It is intended to be plugged into a smartphone. It is a good value-for-money product.

The strength of the Seek Thermal S309P camera module is its ease of integration. The image quality, while being acceptable, remains the lowest of the four benchmarked cameras according to PISÉO’s common testing protocol used for all four thermal cameras, as explained in the report. It has a low performing sensor equipped with basic image processing algorithms.
