摘要： An apparatus and a method for optically scanning a surface of an object under an adverse external condition to which optical components are subjected, such as cameras and lighting sources sensitive to soiling, make use of a first imaging sensor unit having its optical components subjected to the adverse external condition, and being configured for generating reflection intensity image data associated with a target surface. A second imaging sensor unit having its optical components substantially not subjected to the adverse external condition, is configured for generating reflection intensity image data associated with a reference surface. Correction data are calculated from a comparison between the reflected intensity image data associated with the target and reference surfaces, which correction data are then applied to the reflected intensity image data associated with the target surface to generate corrected intensity image data compensating for the adverse external condition.

摘要： Embodiments provide methods, apparatuses, and systems for identification of wood species based on one or more pitch characteristics. A workpiece may be exposed to a beam of radiation from a radiation source. The beam of radiation may cause pitch on or within the workpiece to emit visible light. The emitted light may be imaged and used to determine pitch content, pitch location, a pitch deposition pattern, pitch emission wavelength, and/or other characteristics of the workpiece. One or more of these characteristics may be used to identify a tree species or group of tree species from which the workpiece was cut or manufactured.

摘要： A method and system for stabilizing dry-based density of wood chips from several sources feeding a chip processing stage upstream of a chip refining process, perform on-line estimation of a set of wood chip properties characterizing the wood chips, including light reflection-related property, moisture content and dry-based density, which are used by a reference model capable of comparing the estimated dry-based density with a predetermined target to produce error data, and selectively modifying discharge rate set points of one or more of the wood chip sources to minimize the error data within fluctuation limits around the target. The discharge rate of the wood chip sources is controlled in accordance with the set points to substantially stabilize the dry-based density of the wood chips.

摘要： An apparatus and method for scanning a surface of an article moving along a travel path axis provide a compact sensor configuration. A first sensor unit has a first sensing field transversely directed toward the travel path axis and defining a first scanning zone. A second sensor unit has a second sensing field transversely directed toward the travel path axis and defining a second scanning zone. The first and second sensing fields are crossing one with another at a location sufficiently remote from the first and second scanning zones so as to not adversely affect the generation of sensor output data, while providing a compact arrangement of sensor units.

摘要： A bundled object variability detection system includes an array of sensors at least partially surrounding a bundle of objects, wherein the sensors comprise lasers adapted to obtain physical dimensional data about the bundle. The system also includes a processor for executing computer-executable instructions and a memory for storing computer executable instructions. When the instructions are executed, the processor implements a first module that receives the physical dimensional data from the sensors, a second module that locates a distinct cross-section of a singular object within the bundle based on the physical dimensional data, a third module that determines a model of the singular object based on the located cross-section of the singular object, and a fourth module that analyzes the model to determine if the individual object embodies one or more distinguishing characteristics.
