2018 台中國際花卉博覽會 光養聯覺

As an entry corridor to the exhibition, the team attempted to create immersive “Rinsing Sensory” experience, so as to deconstruct the normal cognition of the audience on exhibition centers and complete a special welcoming flow in all aspects, from visual and auditory aspects to spatial and atmospheric aspects

團隊獲得築點設計的邀約,參與 2018 台中國際花卉博覽會外埔園區樂農館的單元創作。樂農館以「一方地,千畝田,以農為樂」為策展理念,在開闊的地景式展間,以農業、生活和人文為核心,談論土地、作物以及農人的故事。稻米、水果、蕈菇、茶葉四種在台灣的重要作物成為主展區展示背景,在其上探討台灣農業由生產、生活及至國際化的發展進程,發掘農人們「以農為樂」的驕傲。


With“Phototrophic Plants”as the main concept, image designs are projected onto plants, translating and enhancing the attitude and traits of the four main characters:“ Rice, Fruits, Mushrooms, and Tea Leaves.” Using the monitors as a patchwork through the corridor, through continually stacked and abundant images, along with unending compression of space, a fantasy blend of“ organic”and “ geometric ”coexistence. This will allow the audience to obtain a sense of openness in all areas when entering the indoor exhibition area.




Due to the demands of this project, visual effect personnel had to work on the visual effects to be projected on the plants on-site. And because the site is mainly outdoors, in order to avoid light pollution, the personnel can only carry out this task at night. And not wanting to sleep late, the time is very limited. In response to this challenge, we developed two tools to complete this task.


  • Projector-Camera Calibration Using Gray Code Patterns

Simply speaking, through this technology, the visual effect personnel can obtain an image, and this image can be viewed as “the picture seen from the projector. The principle of this technology is gray code patterns are projected on the objects where we need projection mapping using the projector. A camera is set up near the projector lens to record the imaging of the gray code patterns on the video-taped objects. Through calculating the projector-camera relation using the computer, we are able to simulate an image where the camera picture is converted to one that is from the perspective of the projector.
Actually, there are already some ready-made tools to complete this function; however, the images produced from these current tools are all in black-and-white and the details and accuracy are just barely satisfactory. In response to the quality requirements of the visual effect personnel, the team developed this tool on their own.
  • Projector-Camera Calibration Using Gray Code Patterns

簡單的說,透過這個技術,視覺人員可以取得一張影像,而這張影像可以想像成「投影機看到的畫面」。這項技術的原理是,投影機於我們需要 Projection Mapping 的物體上投上 Gray Code Patterns,架設一個接近投影機鏡頭位置的攝影機,紀錄 Gray Code Patterns 於被攝物上的成像,透過電腦計算出投影機與攝影機間的關係,即可模擬出一張將攝影機畫面轉為投影機視角的影像。

  • Real-Time Visual production Using NDI

After obtaining the image from the perspective of the projector, the visual effect personnel still encountered an issue, before projecting, there was no way to preview the visual effect on plants. Therefore, the personnel hoped that there was a system that can provide real-time visual projection editing, where one wouldn’t need to repeatedly calculate and export visual files. So, we made plug-ins for software such as Photoshop and After Effect, where the visual within the production software is immediately exported to the projection system. We used the Network Device Interface (NDI) as the interface for image transmission. NDI is a technology for internet two-way audio-visual signal transmission, where IP Ethernet networks is the main way of connection. Thus, this also let our system achieve a wireless working environment through WIFI.
  • Real-Time Visual production Using NDI

取得投影機視角的影像後,視覺人員還有一個難題,在輸出影像之前無法預先預覽視覺在無物上的效果。所以希望完成一個供視覺可以即時編輯投影的系統,而不需要反覆的運算與匯出視覺檔案。於是我們於 Photoshop、After Effect 等軟體製作外掛,將製作軟體中的視覺即時的輸出到投影系統中。我們使用 NDI (Network Device Interface) 做為畫面傳輸的介面,NDI 為一種網路雙向影音訊號傳輸的技術,使用 IP (Ethernet networks) 乙太網路為主要連接方式。也因此讓我們的系統經由WIFI達成無線的工作環境。
