Building Photogrammetry: Comparing Camera Results of iPad VS DSLR

DSLRfig1

If 800 people are working on the iPhone camera, would this mean that smartphone / tablet cameras will soon match the performance of DSLRs?

The short answer is “No”, as long as the camera sensor size is not increased.  A larger camera sensor allows the capture of more light and reduces noise levels. Their applicability to smartphones / tablets will always be limited, however, since a larger sensor size would also require a larger lens, which would not be very practical for a smart device.

Use your metrology software with your iPod, iPad or iPhone without the internet – BuildIT Tips & Tricks

Using Build!IT with iTeleport on the iPhone

Imagine: You’re alone on the job using your laser tracker to measure a large part, such as an airplane fuselage or a machinery roll in a paper mill. Your computer is set up close to the laser tracker and power supply. You climb the scaffolding to access the feature you want to measure and start measuring using your 4-button remote. After a few thousand samples, something happens. Maybe you lift the SMR by accident because there is little bump on the surface.  Maybe you want to verify the settings, or you would like to view the previewed cylinder.  Whatever the case may be, it means that you must climb back down and return to your laptop in order to accomplish the task.  This is a common enough scenario.  Wouldn’t it be better to be able to manipulate your metrology software without leaving your part? Here at BuildIT, we recommend iTeleport to remote access your metrology software securely. Read More
