ABSTRACT:
A user-friendly video measuring system employing a TV camera having a two-axis array of photosensors, a memory, a monitor, a keyboard and a joystick. The camera takes a first picture, which is stored in memory and displayed on the monitor. In response to a series of menus, an operator uses the joystick to manipulate a cursor on the monitor to locate a series of start search points for the first picture, and to select gradient threshold for one or more features. Both the start search points and gradient thresholds are stored. The operator also selects and stores tolerances for the measurements. A second picture is taken and examined, commencing with the stored start search points, to determine whether the gradients exceed the stored threshold.
