Panomorph

Panomorph is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Panomorph rather than just read about it. In short: A panomorph lens is a particular type of wide-angle lens specifically designed to improve optical performances in predefined zones of interest, or across the whole image, compared to traditional fisheye lenses. Some examples of improved optical parameters include the number of pixels, the MTF or the relative illumination.

Key takeaways

Panomorph belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Panomorph to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Panomorph from memory before moving on to harder problems.

Reference excerpt

A panomorph lens is a particular type of wide-angle lens specifically designed to improve optical performances in predefined zones of interest, or across the whole image, compared to traditional fisheye lenses. Some examples of improved optical parameters include the number of pixels, the MTF or the relative illumination. The term panomorph derives from the Greek words pan meaning all, horama meaning view, and morph meaning form.

History The origin of panomorph technology dates back to 1999 from a French company named ImmerVision now headquartered in Montreal, Canada. Since the first panomorph lenses have been used in video surveillance applications in the early 2000s, panomorph lenses are an improvement on existing wide-angle lenses in a broad range of applications.

Technology Traditional wide-angle lenses have significant barrel distortion resulting from the compromise of imaging a wide field of view onto a finite, flat image plane; and non-uniform image quality due to the off-axis optical aberrations increasing with the field angle; and significant relative illumination falloff due to the cosine fourth illumination law. To improve the optical performances of the resulting images in predefined zones of interest or in the whole image, panomorph lenses can use one or many strategies at the optical design stage, including:

targeted optical distortion, modulated across the field of view, to vary the magnification and increase the number of pixels in the zone of interest. optical anamorphosis to create a non-spherical image footprint to better match the sensor anamorphic ratio and increase the total number of imaged pixels in the whole image. optimally balanced variegated optical parameters (MTF, magnification, relative illumination) to harmonise the image sensor in specific applications and thus equalize the resulting image quality across the whole image. The zones of interest or whole image improvements resulting from using any of these design strategies in a given panomorph lenses enable improved optical performances compared to other traditional wide-angle lenses.

Imaging software No matter the strategies used to improve the performances in zones of interest, each panomorph lens is designed with specific parameters such as the object-to-image mapping function. Precise specifications of these design parameters for each panomorph lens is encoded in their unique RPL (Registered Panomorph Lens) code to allow de-warping algorithms to process the image and properly display the final image. The display is optimized to keep advantage of the improved performance in the zone of interest created by the panomorph lenses as opposed to algorithms for fisheye lenses which employ a linear mapping function to de-warp the image without any considerations for their departure from a perfect linear mapping ( f θ {\displaystyle f\theta } distortion).

Applications By providing wide-angle images with zones of interest, panomorph lenses are often designed with specific applications in mind. Panomorph lenses have already been used in various industries, including:

Broadcast television Mobile communications Virtual reality cameras Action cameras Wearable cameras Security and surveillance Automotive Endoscopy Aerospace Drones

Worked examples

Example 1 — a first encounter with Panomorph

Start with the simplest possible case. Write down what Panomorph claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Panomorph before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Panomorph ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Panomorph

In research: Panomorph appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Panomorph in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Panomorph is common in secondary-school and first-year university syllabi. It links to neighbouring topics Digital imaging, Imaging, Lenses, so understanding it makes those chapters shorter.
In everyday life: Look for Panomorph outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
