FPV Thermal Imaging Camera — 384×288 CVBS, 50 mm Lens (آنالوگ)

نمای کلی

This FPV thermal imaging camera is a small, سبک وزن, آنالوگ (CVBS) thermal module specially designed for integration into drones, گیمبال ها, pods, and other aerial platforms. It outputs standard composite video (NTSC/PAL) and supports a 50 mm thermal lens, providing a narrow field of view ideal for long-range detection. The internal sensor is an uncooled vanadium oxide (VOx) micro-bolometer operating in the long-wave infrared (8–14 µm) باند. The 384×288 resolution and tailored signal processing deliver a robust thermal video feed compatible with existing FPV analog video systems.

Key design goals:

• Compatibility with analog FPV systems (no need to replace entire video chain)

• Compact form factor, وزن کم, مصرف برق کم

• Flexible configurations (لنز, video polarity, imaging modes)

• Rugged thermal performance across temperature extremes

• Simple control via UART for color mode, flip, calibration, و غیره.

This is intended as a premium (but still relatively cost-sensitive) thermal module for professional or advanced hobby use (search-&-نجات, بازرسی, long-range observation, و غیره).

Options & Variants

When designing or ordering, you can consider a range of optional variants or modifications:

1. Alternate Resolutions
    While our base spec is 384×288, you may wish to support 256×192 or 640×512 (higher cost, سنگین تر) as alternative SKUs. Many similar products offer such resolution variants.

2. Lens Variants
    Although 50 mm is your target lens, you may also offer 35 میلی متر, 25 میلی متر, 19 میلی متر, 15 میلی متر, 9.7 میلی متر, و غیره. Many existing modules support 9.7 mm or 6.8 mm lenses.
    You could also provide optional focus adjustment or interchangeable lens mounts.

3. دیجیتال / USB Variant (UVC)
    Provide a variant where instead of analog CVBS, the camera outputs UVC (USB Video Class) digital video—useful for PC / سیستم های تعبیه شده. (This is often offered as a custom upgrade.)

4. Video Temperature Overlay / OSD
    Add firmware to overlay max/min/average temperature, crosshairs, center marks, و غیره. This overlay can be included in the video stream (if camera supports it).

5. Preset Flips / Mirror Option
    Before shipping, you can pre-configure flip (عمودی / افقی) orientation to match the intended mounting (به عنوان مثال. upside-down mount).

6. Customized Connector / Pin out
    Standard interface: 5 پین ها (قدرت, GND, CVBS, UART_TXD, UART_RXD). You can optionally reassign or combine pins, or include an on-board connector (به عنوان مثال. JST, Molex) or cable harness.

7. Casing / مسکن
    Offer optional protective CNC aluminum cases, lens covers, window windows (به عنوان مثال. germanium window), mounting brackets, gimbal adapters.

8. سفارشی سازی سیستم عامل
    Support custom commands, alternate palettes, custom behaviors (به عنوان مثال. auto zoom, dynamic exposure) as per client firmware requests.

9. کالیبراسیون / Factory NUC Tuning
    Perform factory calibration / mapping for improved image quality, bad pixel correction, drift compensation.

10. Thermal Sensor Extras
     Possibly include reference thermistor or ambient temperature reading to improve temperature stability or compensation.

مکانیکی & Mounting Considerations

• Lens protrusion & وزن
   The 50 mm lens will add length, وزن, and moment load. Ensure the drone / gimbal mount can support the lens dynamically (ارتعاش, inertia).

• Thermal window material
   Lens windows often require IR-transparent materials (به عنوان مثال. germanium, ZnSe). Ensure your design accommodates the proper protective window.

• Center of gravity & balance
   Because the thermal module is likely offset or elongated by the lens, ensure you account for the moment arm on the drone/gimbal mount.

• دفع گرما & airflow
   Although the module is low-power, plan for adequate airflow and heat path, especially in housing or sealed pods.

• Vibration isolation
   Use soft mounts or dampers if the drone vibrates heavily; the sensor may degrade with excessive vibration.

• Lens focus & adjustment
   If the 50 mm lens is fixed-focus, specify target focus distance. If adjustable, provide a mechanism (set screw, knurled ring, و غیره).

• Connector orientation / clearance
   Ensure the 5-pin connector orientation is accessible in your drone frame or pod.

یکپارچه سازی & Interfacing

• قدرت
   Supply a stable DC voltage between 5 V and 17 V. Use clean regulation and bypass capacitors to avoid noise coupling into sensitive thermal electronics.

• Video chain compatibility
   Because output is CVBS, the thermal camera can feed into standard FPV video transmitters (VTX) or video multiplexing setups, then to ground station analog video receivers (VRX).

• UART Control
   Use a UART (3.3 V TTL) interface to send commands (به عنوان مثال. change palette, flip mode, بزرگنمایی, calibration). Communication protocol typically will include command IDs, parameter bytes, and possibly checksums.

• Signal Infrastructure
   Shielded coax (به عنوان مثال. RG174) or twisted pair + coax, depending on your layout. Use appropriate impedance matching and connectors (به عنوان مثال. SMA, BNC, or mini coax).

• کالیبراسیون / NUC
   At startup or on command, the module may require a shutter-based calibration (NUC). Ensure your integration allows the shutter action (if present) unobstructed field of view.

• Temperature overlay / OSD (اختیاری)
   If you enable OSD, the module may embed numeric temperature readouts in the analog video output. This may require additional firmware or digital overlay logic.

• Mount orientation / flip
   Because it may be mounted inverted, support flip / mirror settings so video appears correct to the pilot.

• تأخیر & synchronization
   Minimize latency in video path; ensure synchronization with video transmission chain.

پرسش و پاسخ (Based on Your Original Questions)

س: Can you provide a 3D file?
آ: بله, a 3D (CAD) مدل (به عنوان مثال. STEP, STL, IGES) of the camera housing + lens flange can be provided prior to production. This helps you verify mechanical clearance and mounting compatibility.

س: Can you offer UVC (USB Video Class) instead of CVBS?
آ: بله. We can provide a variant that includes a UVC digital output module (رابط USB) in place of (or in addition to) CVBS, though the additional electronics may increase cost, اندازه, and power.

س: Can the thermal imaging camera display temperature in the video?
آ: بله. We can embed temperature overlay (حداکثر, دقیقه, متوسط) in the video feed. If digital (UVC), it’s easier; for analog (CVBS), we can insert OSD overlay circuits or firmware to overlay temperature data. با این حال, this sometimes reduces the analog video dynamic range slightly.

س: How do I interface settings (like flip or mirror)?
آ: The camera supports UART (3.3 V TTL) commands to control settings: color mode, flip/mirror, calibration, بزرگنمایی, و غیره. We can provide a command protocol (به عنوان مثال. command bytes, checksums). همچنین, before shipping, we may preset a flip / mirror mode per your mounting orientation.

س: Will the camera work with my existing FPV video system, or do I need a new system?
آ: Because the output is CVBS analog, it is compatible with standard analog FPV transmitters (VTX) و گیرنده ها (VRX). You should not need to replace your entire video chain, just integrate this module in place of (or alongside) your visible-light FPV camera. The only caveat is power, mechanical mounting, and video path latency.

س: Does this thermal camera work with my phone (for e.g. checking hidden cameras)?
آ: If you choose the UVC variant (دیجیتال), you can connect via USB to a phone or computer and view video / temperature data. If you stick with CVBS, you’d need a CVBS-to-USB converter (capture card) or a monitor that accepts analog composite input.

س: Does the FPV thermal camera support changing display color modes and digital zoom?
آ: Yes — via UART commands or onboard firmware, the camera supports up to ~15 pseudo-color palettes and digital zoom (به عنوان مثال. × 1, ×2, ×4, ×8).

س: What lens sizes are available?
آ: While your spec uses 50 میلی متر, optional lens sizes include 35 میلی متر, 25 میلی متر, 19 میلی متر, 15 میلی متر, 9.7 میلی متر, 6.8 میلی متر, و غیره. Many suppliers offer these as customization options.
