LAP Application v4.4 Available for Beta Testing

Although this is just a minor version number increase, the new v4.4 packs a few crucial improvements:

• easy calibration
• high-contrast mode at full speed
• missing data points display
• taking photos in reduced resolution

What’s inside?

Easy Calibration

Those bloody chevrons! It wasn’t always easy to tweak the exposure, sensitivity, and crop window to get the green circles where they belong.

V4.4 comes with an improved calibration pin identification algorithm. It’s more robust, does not care about the sensitivity setting, and in most situations it can even do without cropping the view.

High-Contrast Mode

If you’re often on the road, it happens. Turning off the ceiling lamps, rolling down the window shades, repositioning the profiler to a different spot – all in order to prevent the lower camera from looking into anything that’s comparably bright to the laser. Sure, the high-contrast (HC) mode solves this, and it’s already been available in older app versions. However, the profiling performance degradation is quite noticeable when it’s turned on.

LAPs with serial numbers LAP292 and later support a direct electronic HC mode. What does it mean? Simply put, you get the HC mode while keeping full profiling performance. However, it also needs to be supported on the software side – and that’s what v4.4 does.

So, what can you do if your LAP is older? Let’s discuss how we can make it possible.

Missing data points display

We’re well aware of the technical limitation. The LAP is an optical device. As we always say, you can only get a data point from a spot that’s both illuminated by the laser and seen by the camera. With more complicated shapes, it may get tricky to find the suitable capturing position to take the complete profile in one shot. What’s even trickier is that the older software does not clearly show you which data were really captured, and which ones were just bridged over.

This is no longer the case with v4.4. When you choose to show data points, the distinction between captured and interpolated data is immediately visible.

Taking photos in reduced resolution

In the new app, you can choose between taking the photo in full resolution, or in resolution divided by 2, 3, or 4. This saves precious DB storage space if you don’t need the full quality. It’s not a big deal with the current 5-megapixel camera – however, a new 20-megapixel upgrade is coming, so DB space will be taken up more quickly than before.

Why beta?

So, why don’t we just release the latest and greatest LAP app through our standard support page? It’s because there’s another revamped part of the new software – it handles the interfacing between the computer and the profiler in a brand new way. The switch is necessary to support the mentioned electronic HC mode and some cool upcoming add-ons for the LAP – RTI ring, upgraded photo camera.

However, it also means that the compatibility of all the LAPs out there with all the computers they connect to – which we’ve been polishing throughout the years – might be at risk. That’s why v4.4 will be kept in beta testing mode for a couple of weeks – many thanks beforehand to the early adopters who give it a try and report anything that’s not working well. 

Please note that there are some really old profilers unable to run v4.4. We’re talking about some of those delivered back in 2019 and 2020. These legacy units will need a hardware upgrade to continue receiving software updates.

How do I get the new software?

It’s available for download here. As of today, there’s only a Windows version – the one for macOS is coming shortly.

The new app is completely backwards compatible. Nevertheless, it’s always a good idea to back up your database before the update.
