This invention disclosures a six degree-of-freedom (DOF) measuring system and method. The measuring system comprises a tracking measurement device and a target. The tracking measurement device includes a processor, a camera and two rotation optical components connected with the processor respectively, which are arranged in sequence. The camera boresight and the optical axis of two rotation optical components are coaxial, and each rotation optical component can rotate independently. The target is mounted on the tested object, which contains at least three markers with known distance constraints. In addition, at least one marker does not coincide with the midpoint of the line connecting any two of the remaining markers. Compared with the prior technologies, this invention realizes a dynamic real-time measurement of six DOF for the tested object. In the process of measurement, only the target is fixed on the object. The target has the advantages of simple structure, less influence on the actual operation of the target and easy use. Meanwhile, the calculation process of 6 DOF measurement is simplified, and the real-time and reliability of the measurement method is improved.

To provide a robot system capable of ensuring safety while giving consideration to the occurrence of a trouble in image capture means. A robot system with a camera for monitoring a robot comprises: current position model generation means that generates a current position model for the robot based on current position data about the robot and robot model data about the robot; simulation image generation means that generates a simulation image of the robot viewed from the direction of the camera based on set position data about the camera, set position data about the robot, and the current position model; detection means that compares the simulation image and a monitoring image acquired from the camera to detect the robot in the monitoring image; and safety ensuring means that ensures the safety of the robot system if the detection means does not detect the robot in the monitoring image.

A method for object tracking. The method includes capturing, using a camera device, a sequence of images of a scene, detecting, based on a pattern of local light change across the sequence of images, a light source in the scene, comparing, in response to detecting the light source, a location of the light source in at least one image of the sequence of images and a current position of a transport robot to generate a result, and generating, based on the result, a control signal for moving the transport robot toward the light source such that the light source aligns with a target position within the field-of-view.

An alignment system for an imaging sensor of a coordinate measuring machine incorporates a reference surface associated with a stage of the measuring machine but instead of imaging the reference surface as a location marker, the reference surface is incorporated into a combined imaging system together with the imaging sensor for imaging a feature associated with the imaging sensor. The imaged feature can be an internal part of the imaging sensor, such as an internal aperture, or an external feature in a fixed relationship with the imaging sensor, such as a lens hood.

This robot controller causes a robot to follow a target, while a transfer device moves the target, by using a detection result obtained by a movement-amount detecting device that detects the amount by which the transfer device moves the target. When the value of any one of the speed, the acceleration, and the jerk of the target calculated based on the detection result obtained by the movement-amount detecting device or the pattern of the speed, the acceleration, and the jerk deviates from the predetermined reference, the robot controller performs predetermined reporting or stops the robot.
