Jan Willem Wolters, chief executive officer of CycloMedia Technology, served as the distinguished speaker at the September meeting. He discussed the company's specialization in systematic visualization of environments based on panoramic photographs, called cycloramas. Peter de With, vice president of video technology, CycloMedia, described the techniques that are used to obtain a complete database of the Netherlands, including data from more than 40 million photographs. He discussed several applications: fixed and moving rigid objects, scene understanding/behavior and interaction and information filtering, and analysis of aerial photographs. Ron Borstel, account manager, defense and homeland security, CycloMedia Technology, shared the properties and revolutionary technology of the DCR-7, a recording vehicle that generates accurate cycloramas with a position accuracy of less than 10 centimeters at driving speeds of up to 80 kilometers per hour. The goal for the vehicle is to build strategic databases. The DCR-7 uses specially equipped cars and aircraft to record millions of images and their exact geometrical references and store them in a database. Local and national government agencies, construction and utility companies, security and defense organizations, and other companies use the capability.
