The best of Document imaging for You Now

Some 3d scanners require a patterned background to determine the position of the scanner relative to the object. This is easy to achieve. It is necessary to try to avoid "uniform" backgrounds or use other objects in the scene. But you need to avoid moving objects in the scene, because this can confuse the scanner. For the Document imaging this is important.

Foreign material: Make sure that there are no foreign objects on the object being scanned. They will not interfere with the scan, but the process of processing the scan can be difficult, because they will need to be deleted.

Support: On some objects there may be undercuts that cannot be scanned without lifting the object. If you raise the product, then the scanning process will fail and everything will have to start all over again. Initially, look at the support on which you place the product and from where you can "get" to all the elements of the object.

Color and lighting: Some 3d scanners capture the color and texture of an object. But the correct color can only be obtained if you use the illumination of the object correctly. Natural light is best suited. But 3d scanning is also done indoors. Therefore, it is necessary to take into account that the object is lit evenly from all sides. If the lighting is uneven, the non-illuminated side will be dim compared to the illuminated one.

Cleaning: After the scan is complete, you will need to convert the scan to a 3d model. Some companies supply their processing software with a 3d scanner. In this case, the program will do everything for you. But it may be that you have to do this with your own software that you have. Then you will need to fill in the holes, smooth the surfaces, simplify the complex mesh of the object.

Perfect Aperture cards for Your Choices in Every Case

When buying a 3d scanner for the first time, the buyer wants to receive the most accurate copies of the scanned products. Someone starts to get it right away, while someone spends a lot of time getting the desired result. From personal experience I will say that every time I scan a new product, I come across pitfalls and problems.

Naturally, when a problem arises, we immediately go to the Internet to find answers to our questions. And in most cases we find them, but, unfortunately, there is very little that can be found on the network on the topic of 3d scanning. Therefore, the idea was born to write advice on what and how to do to get the desired result. The article will be interesting for both a novice and an experienced owner of a 3d scanner. For the Aperture cards this is important.

In this article, we will cover 10 tips for scanning with hand-held 3d scanners. These tips will be relevant for cheap, home-made 3d scanners based on Microsoft Kinect and for hand-held 3d scanners costing up to $ 50,000.

Tips for scanning with a handheld 3d scanner

Setup time: Getting a good scan takes considerable time. It includes not only the time of direct scanning. Be prepared to spend a lot of time setting up the environment of the scanned product and setting up the equipment.

Cable length: Hand scanners are equipped with cables for connecting to a computer or laptop. Before starting a scan, it is advisable to consider the length of the cable so that you can scan the product from all angles.

Feedback: Unlike stationary 3d scanners, manual ones require constant feedback. Therefore, before starting a scan, make sure that the monitor is in your direct line of sight.

Resolution: Some hand-held 3d scanners, especially expensive ones, suggest scanning options before scanning. And the natural desire will be to set high resolution. But in this case, the movements of the scanner should be very slow. This can be difficult, because the scanner has significant weight. For starters, it’s better to determine what resolution is required you may not need the highest.

Corners and undercuts: Before starting a scan, analyze the product for corners and undercuts that may be difficult to scan. Think in advance about the path of the scanner to capture them and scan well.
