Abstract
A method and a laser-optical detection system including a laser projector, a camera, a control device which is designed and configured to actuate the laser projector and the camera in order to determine features of the object, and a sensor unit. The control device is configured such that, as a function of the characterizing signal obtained by the sensor unit relating to an approach or the presence of a person in a critical spatial proximity to the laser projector, the exposure parameters of the camera are adjusted as a function of the reduced maximum irradiation intensity of the laser projector in relation to the current irradiation intensity of the laser projector. A robotic workstation includes a laser optical detection system of this type.
Claims11
A method for controlling a laser-optical detection system (1), comprising the steps:
- projecting laser light of a predetermined pattern in a predetermined wavelength range with a predetermined irradiation intensity (Ev) onto an object (2),
- optically detecting the pattern reflected from the object (2) which has been projected onto the object (2) by means of a camera (3), which records an image (4) of the reflected pattern through an optical system (5) under predetermined exposure parameters (P),
- determining features of the object (2) based on the recorded image (4) of the reflected pattern,
- reducing a maximum irradiation intensity (Ev) of the laser light to a permissible value as a function of an approach or presence of a person (9) in a critical spatial proximity to the laser light, and
- adjusting the exposure parameters (P) of the camera (3) as a function of the reduced maximum irradiation intensity (Ev) of the laser light.
