With the constant evolution of technology, projectors are gradually becoming the devices of choice for watching high-quality movies and making superb presentations. But there are different variations of projectors, like mini projectors, home theater projectors and so many other types. So, sometimes, it can be hard to determine the best projector for projection mapping.
But first, what is projection mapping?
Projection mapping is a process by which light illuminates a surface to form a definite image. It is a technique in which object surfaces are used as display surfaces for video projection.
Projection mapping can be done with almost any kind of projector, but there are key features that a projector must have for proper projection mapping. But before we delve into how to choose the best projector, it’s crucial to understand the limitations that exist pertaining to where the projector will be used. Ask yourself: “Where will it be used? Is it going to be in a small conference room or a large open space?” The space required for the projector to function will greatly determine what projector to choose. These limitations will be further explained as you read on.
There are a few major things you need to consider when choosing a projection mapping projector: image size and throw, brightness, resolution and the projector screen material. The following tips will help you make informed choices when picking a projector for projection mapping.
Image size and throw
The throw of a projector is simply the distance between the projector and the projector screen or projection surface. Projector throws come in any of three categories: long throw, short throw and ultra-short throw. Projectors in each of these categories are, therefore, used in different space sizes.
Projectors with long throws can be used in wide areas while projectors with short and ultra-short throws are better used in smaller spaces. This is one of the reasons why there is a level of limitation caused by the space a projector is to be used in.
So, why should image size and throw be so important in determining your choice?
The image size and the throw distance are related technically to form a throw ratio, mathematically represented as: image size/throw distance. This ratio simply shows us the size of projected image with respect to the distance of projection. All video projectors have this ratio.
A ratio of 1.5:1, for example, means a 1.5-foot projection distance and 1-foot width. With this in mind, it’s safe to say that the higher the throw ratio, the higher the projection distance. Long throw projectors generally have long projection distances and smaller image sizes, while the short and ultra-short throw projectors usually have larger image sizes and shorter projection distances.
A simple calculation with the above formula could help you choose the best projector. For instance, once you know the distance you want to project from, and the width of the surface that you wish to use, you can easily use those figures to determine your throw ratio and pick the projector that best suits you. There are Goodee projectors with long throws and short throws. A typical example of a Goodee projector with a short throw is the Goodee YG220 Portable Mini Projector LED Video Projector which has a throw distance of between 1.5 meters and 2.5 meters.

Generally, the brighter the better. But depending on the kind of space the projector is to be used, indoor or outdoor light will affect the quality of the projection mapping. When there is environmental light, this light reflects on the surface of projection and reduces the quality of the image projected. Therefore, it is important to reduce the level of environmental light present.
This said, it’s very important to get a projector that is as bright as possible. This will go a long way in the projection of a detailed image even in the presence of environmental light.
The brightness of a projector is measured in lumens and a standard by the American National Standard Institute has been created which is being used for many projectors. Some of the brightest projectors range from 1000 to 2,500 lumens. The lumen output of projectors is usually on their packs, so you can easily check and choose. An excellent example of a powerful projector with super brightness is the Goodee YG601 Updated LCD Home Theater Projector. Compared to other small projectors, this Goodee projector has a brightness surpassing many others, allowing you to use it even outdoors and still project the best image quality.
The resolution of a projector determines how detailed your image will be. This is because once the image is enlarged, it tends to lose quality. But with a projector of top-notch resolution, that quality is retained.
A projector’s resolution is a very easy feature to recognize because nowadays, manufacturers use it as their selling point. In choosing a projector, the term you should be looking for is “native resolution.” This can easily be found on the projector pack.
The native resolution of a projector essentially means the highest resolution that the projector can produce. Today, the native resolution of a projector is written in different forms like SVGA = 800 x 600, and HDTV resolution of 720p = 1280 x 720. Mini projectors usually have lower resolutions.
If you’re need of a projector that is high in resolution, we recommend the Goodee YG620 Newest LED Video Projector, which has a whopping high resolution of 1980 x 1080.
Projector screen material
This is a tip that’s easy to miss. The material to be projected on is also important in creating the best image possible. Needless to say, the surface should be light-colored, most preferably white. Also, an uneven, or three-dimensional surface would require higher complexity in rendering out. Lastly, avoid flexible surfaces, because they cause image distortions when rendered.
With the above tips, you should be able to make the best decision when choosing a projector for projection mapping.
