1.1 This test method covers the measurement of several key parameters of video systems for remote operations. It is initially intended for applications of robots for Urban Search and Rescue but is sufficiently general to be used for marine or other remote platforms. Those parameters are (1) field of view of the camera system, (2) visual acuity at far distances with both ambient lighting and lighting on-board the robot, (3) visual acuity at near distances, again in both light and dark environments, and (4), if available, visual acuity in both light and dark environments with zoom lens capability.

1.2 These tests measure only end-to-end capability, that is, they determine the resolution of the images on the display screen at the operator control unit since that is the important issue for the user.

1.3 This test method is intended to be used for writing procurement specifications and for acceptance testing for robots for urban search and rescue applications.

1.4 This test method will use the Snellen fraction to report visual acuity; readers may wish to convert to decimal notation to improve intuitive understanding if they are more familiar with that notation. Distances will be given in metres with English units in parentheses following.

1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
