What camera settings are most effective for photogrammetry data?

MegaPixel Matter, Low light functionality is also a BIG plus and will help the programs find the data hidden by shadows. Higher frame rate like the sony cameras are boasting means point click rotate and it will capture EVERY angle and nook/cranny.

Photogrammetry is a technique that involves capturing three-dimensional information from photographs to create detailed and accurate models of real-world objects or scenes. The effectiveness of photogrammetry data depends on several camera settings. Here's a short description of key camera settings for effective photogrammetry. High Resolution Manual Focus Fixed Aperture Fixed White Balance Low ISO Setting Grid Calibration Overlap and Coverage Consistent Lighting Stable Mounting Sequential Capture ETC. By carefully considering these camera settings, photogrammetry practitioners can optimize the quality and accuracy of the captured data, leading to more reliable and detailed 3D models.

Whether you’ve recently picked up a camera for the first time or are looking to hone your skills, getting to know your camera is an important step. Switching from automatic to manual shooting will help you step up your game and try more technical or creative shots. Read on to learn some basic DSLR settings every photographer should know.

I agree with the other posts (low iso, steady shot etc.) I only want to add, that - i had great results with short focal lenght lenses (even 11-24mm) - the importance of masking is usually underestimated: create some garbage mattes - try different softwares for different projects - try "X+X" image aquisition: stand still, and follow the patterns (Left up, right up, left down, right down : this is the first 'x', step left / right about a meter, do the up, down, left, right: this is the + and do the 'X' again. (this is something i read somewhere, but I just dont remember the source, sorry. But it works. Now i need MUCH LESS images... Means... Faster turnarounds.) - and use meshlab ??

Wide-angle lenses have the greater depth of field needed for photogrammetry. Rectilinear lenses have distortion corrected, but can have problems with chromatic aberrations.

With fixed focal length parameter, working distance is also of importance. You need to choose a prime lens with deep depth of field. It will keep subjects in focus most of the time with sharp images.

Prime lens for photogrammetry? Consistent view: No zoom means no field of view shifts, confusing the software. Minimized distortion: Say goodbye to warping and wonky models! Easier alignment: Software loves predictable angles, leading to smoother processing. Bonus: Prime lenses often sharper too!

Just bear in mind anything lower than 100 ISO is artificial. Keep it at 100. Less than 100 the camera is using a program to alter the ISO which can be just a detrimental to quality as going higher ISO.

Y manejarlas de forma manual y una vez configurada que todas las fotos sean con la misma apertura y velocidad para que todo sea parejo.

Also, having a fixed shutter speed and aperture along the photogrammetry is also important as you want a consistent lighting and environment shutter. This consistency helps in obtaining accurate and reliable results during the 3D reconstruction process. Variations in lighting or environmental factors can introduce errors in the captured data, affecting the quality of the reconstructed model

For small object photogrammetry, it is good to consider a photography turntable, a dark even background, a ring light for the camera and a polarizing film for the lights in the set.

Using the Circular Polarizer Filter reduces reflection when trying to capture diffuse albedo. These filters are widely available in many sizes.

Hay que ser muy ordenado y planificar las fotografías, no vaya a ser que olvidaste o te saltaste un ángulo y luego vaya a quedar un hueco en el resultado final.

The amount of overlap between images in photogrammetry is critical for accurate 3D reconstruction. a 60% overlap is typically recommended - with a higher overlap, there's a greater chance of finding matching points, even if there are changes in perspective or lighting.
