Thermal Driving Night Vision System

In recent years, thermal driving night vision system has been increasingly known by people.

The driving assistant system can, without interfering in the normal driving of drivers, improve the driving comfort and safety of drivers. Infrared thermal imaging automobile driving assistant system can facilitate drivers to identify pedestrians in front of the vehicle in advance in the dark (without the night vision assistance system, this kind of identification would be realized quite late).

The thermal driving night vision system is capable of extracting the heat generating object which is not within the lighting vision of the vehicle yet from its background, displaying it in the screen, which greatly improves the driving experience of driver and the driving safety factor.

Infrared Digital Camera Lens

20171023Do security cameras need infrared digital camera lenses to produce infrared video images? How does an digital video infrared camera produce infrared images?

Before we attempt to answer any of these questions, let’s discuss how digital video security cameras work to fully understand their function and how it can relate to infrared image production.

First, a typical contemporary security camera is a digital video camera versus the older legacy analog video cameras. Digital video security cameras are very similar to digital photograph cameras, except that digital video cameras take several digital photographs within a very short time period. On the average, good quality digital video cameras will work at speeds of 30 photographs per second also known as 30 frames per second or 30 fps. Photographs taken at this speed rate, when displayed at the same rate, appear to the human eye as smooth, fluid video.

Digital video security cameras create digital images by using one of two different sensors that transfer light energy into electrical energy that can be measured and used to create a digital video image. One of the sensors is called a Charged Coupled Device or CCD and the other is a Complimentary Metal Oxide Semiconductor or CMOS. These sensor chips are relatively small and for most digital video security cameras range from about 1/4″ to 1 inch in diameter. Generally, but not always, the bigger size of the chip produces a higher resolution image.

The interesting thing about both chips is that they are inherently sensitive to infrared radiation in the near infrared spectrum. No infrared digital camera lens is needed for them to sense near infrared radiation or “light.” This type of infrared radiation is invisible to the human eye however so we cannot detect it. As an example most appliance remote controls (televisions, DVD players, cable TV boxes, etc.) operate by using infrared signals. (Try looking at your remote while pressing a command button – you should see nothing, then look at it again through your digital camera – you should see a flashing white light.

As you can see, your camera is already able to detect near infrared spectrum radiation, so realistically no infrared digital camera lens is required. This is a great value-added feature of the CCD and CMOS sensor chips.

Near infrared radiation is not normally emitted by all objects, i.e. it is not the same wavelength of infrared light that comprises object’s heat signatures. Therefore, your infrared digital video camera needs infrared illumination of the field of view in order for it to produce an image. This is accomplished by using several InfraRed Light Emitting Diodes or IT LEDs to illuminate the field of view. Generally, the more LEDs that are used, the longer the infrared range of the camera.

Therefore it is not necessary to used an infrared digital camera lens to make your digital camera take infrared video images. However, it is necessary for the target area to be illuminated with near infrared spectrum light, so IR LEDs or other infrared illumination is required.

One thing about this business of infrared digital camera lenses and imagery. Security cameras are often marketed as day/night or true day/night cameras, meaning they can take high quality color digital video in visible light conditions and high quality black and white or monochromatic digital video in dark conditions (infrared light does not express “colors.”)

A typical day/night camera uses software or circuitry to filter out the infrared light that it picks up during visible lighting conditions. If it didn’t the extra infrared radiation would combine with visible light to make a lesser quality image. True day/night cameras however, have an internal filter that is used during visible lighting conditions to filter out the infrared light.

This filter is often called an IR Cut Filter (InfraRed Cut-off Filter). It produces a much cleaner, brighter, and higher quality video image. Under infrared conditions, the filter is mechanically removed to allow penetration of infrared light to the sensor. Generally, “true day/night” cameras are more expensive because they contain this filter and the mechanism to remove and replace it.

So as you can see, digital video security cameras by the nature of the electronic sensor they use, can already detect infrared radiation without the need for an infrared digital camera lens. In fact, IR LEDs are more likely needed to create IR light and filters are needed to suppress the infrared radiation during visible light periods to produce a higher quality image.

How Thermal Imaging Camera Works

Pretty obvious. We make images of heat. Think about how an image is made with your smartphone camera. Visible light reflects off the objects you want to image, that light comes into a lens, it is focused on a sensor, and an image is delivered. We do the same thing with heat coming from the object. We have been thermal imaging camera for close to 25 years, since the first solid-state thermal imagers were introduced. You might wonder how do you focus heat? What kind of sensor detects heat? How do you display heat? All good questions.

Just as in any science or technology, there are armies of brilliant people making thermal imaging camera products better all the time. Just like the evolution from early PCs with C:\> to how we function with smartphones, thermal imagers have come a long way. But very simply, thermal imaging camera is your thermal scene, a lens, a sensor, and a display, simple as that.

Thermal Binocular vs. Bi-Ocular; know your devices

Seeing the Difference: Thermal Binocular vs. Bi-Ocular Thermal Night Vision Cameras

For many people the difference in the words thermal binocular and bi-ocular are not apparent or clear at first. Thermal binocular sights consist of two eye piece channels that deliver a slightly different image to each eye. In return the brain compiles the two images to create one image. When paired with night vision technology this information is relayed to the viewer via two optical channels while amplifying light to display an image.

Bi-Ocular Differences

A bi-ocular night vision thermal imaging camera is composed of two separate eye pieces, but only one optical channel, thus delivering one image to both eyes at the same time. A bi-ocular thermal camera detects infrared light, which is given off by the heat of an object in view, the microbolometer lens detects heat and displays the thermal image to the viewer.

Benefits of the Bi-Ocular

The benefit of using a FLIR H-Series Bi-Ocular thermal night vision camera during patrol, covert surveillance, or security mission is the extreme sensitivity and low temperature readout. The presence of a suspect or vehicle with a recent source of heat is clearly seen through fog, low light situations, and tree cover.

How A Thermal Imaging Camera Works

To fully understand how a thermal image, or thermogram is produced, some background knowledge of the physics of light is needed.

Light is emitted in waves. The amount of energy in each light wave is related to its wavelength; shorter wavelengths have more energy.

Visible light is made up of a spectrum of colours (those you seen in a rainbow), in this spectrum violet has the most energy and red has the least.

As well as the visible light spectrum there are also UltraViolet (UV) and InfraRed (IR) Spectrums either side of it. These can’t be seen with the naked eye.

The IR Spectrum is the part of light that we’re interested in when capturing IR images.

Infrared light can be split into three categories;

1. Near IR; closest to visible light, near infrared has wavelengths ranging from 0.7 to 1.3 microns (or 700 to 1300 billionths of a metre);

2. Mid-IR; has wavelengths ranging from 1.3 to 3 microns;

3. Thermal-IR; has wavelengths ranging from 3 to 30 microns.

You’re probably very familiar with both near and mid-InfraRed as they’re used by a variety of electronic devices, e.g. remote controls. Thermal-IR makes up the largest part of the IR Spectrum and is also known as heat. Thermal-IR is the part of the Spectrum we’re interested in for Thermography (Thermal Imaging).

The key difference between Thermal-IR and the other categories is that it’s emitted by an object instead of being reflected off it.

Animals emit IR radiation as a result of normal physiological processes. About 60% of all the heat an animal produces passes into the surrounding air as radiant heat, or heat photons. The remaining heat is lost to the environment by evaporation (25%), conduction to objects (3%) and conduction to the air (12%).

An IR camera is used to measure the heat photons emitted from the animal and to convert them into electrical impulses which are then displayed as coloured images on a monitor. This visual image graphically maps the animal’s body temperature and is referred to as a thermogram. The heat detector, or microbolometer within the thermal imaginng camera can detect differences in temperature of less than 0.05oC, which is 40 times more sensitive than the human hand. More reading about heat detectors can be found on Wikipedia.

These pictures were taken with the thermal imaging camera, which has the ability to simultaneously take and then fuse together visible light and thermal images.

Wool is a fantastic insulator, so heat is not emitted through her fleece, and this area doesn’t even register on the thermal scale. The corners of the eye are always the warmest points on any animal as the skin is thinner here, allowing heat to radiate out easily. As the ear is concave, the infrared radiation bounces around and concentrates in this area making it appear warmer.
