摘要： Introduced here is a system for optically tracking displacement with high precision across one or more axes. To track displacement of an object, images that are generated by a plurality of optical sensors can be compared against one another. For example, images that are generated by a first optical sensor can be compared against images that are generated by a second optical sensor. Because the first and second optical sensors are in a fixed spatial relationship with one another, displacement of the object can be established based on the degree to which a given image generated by the first optical sensor matches another image generated by the second optical sensor.

摘要： The present disclosure extends to methods, systems, apparatus, and computer program products related to a cable-based measuring system. The cable-based measuring system includes a cable, comprising an inner cable member configured to move linearly within an outer cable housing. The measuring system also includes a measuring device configured to generate measurement information regarding movement of the inner cable member relative to the outer cable housing using one or more encoders. A computer system receives the measurement information from the measuring device. The measurement information indicates length as a function of time, and represents three orthogonal dimensional measurements of a three-dimensional object. Based on the measurement information, the computer system identifies a length of each dimensional measurement, including a length, a width, and a height of the three-dimensional object. The computer system then initiates creation of a box template sized to accommodate the three-dimensional object and/or updates a database.

摘要： An exemplary method for monitoring a package on a conveyor may include emitting a plurality of infrared beams, detecting one or more of the emitted infrared beams, calculating a package height using the detected infrared beams, determining whether the package height exceeds a predetermined threshold, and when the package height meets or exceeds the predetermined threshold, sending a signal indicating a height of the package exceeds the predetermined threshold. A package size detector may include a transmitter including a plurality of light sources and positioned on a first side of a conveyor, and a receiver positioned on a second, opposite side of the conveyor, including a plurality of light sensors, each of the plurality of light sensors being configured to detect light emitted from the plurality of light sources. A controller may be configured to determine whether a package height exceeds a predetermined threshold.

摘要： A hand-held OCTG length measuring apparatus has hollow upper and lower bodies, a hand grip extending generally downward from the hollow upper body near the first end and including a source trigger, and a sensor housing extending generally downward from the hollow upper body. The sensor housing encloses a TOF source operatively connected to the source trigger. The hollow lower body shaped to include a frontal cavity positioned generally under the source housing, the frontal cavity having attached thereto a pipe end alignment bracket. The upper hollow body and the lower hollow body connected at a lower end of the hand grip and at a lower end of the sensor housing. The apparatus employs a minimum 40,000 lux laser (at 18 to 25 feet) and a polarized, diamond-grade reflector, to afford reliable, repeatable OCTG length measurements.

摘要： A method of measuring objects that are conveyed in a conveying direction comprises the steps that
(i) a first object edge of a conveyed object is detected at a first measurement position by means of a first optoelectronic sensor,
(ii) the first object edge or a second object edge of the object is detected at a second measurement position, which is spaced apart from the first measurement position in the conveying direction, by means of a second optoelectronic sensor that is spatially resolving at least in the conveying direction,
(iii) a time difference between the detection of the first object edge at the first measurement position and the detection of the object edge detected in step (ii) at the second measurement position is determined,
(iv) a transit time is determined in which the object edge detected in step (ii) moves through a predetermined measurement path,
(v) the object speed is determined based on the transit time and a length of the measurement path, and
(vi) the length of the object is determined based on the determined time difference and the determined object speed.-

摘要： There is provided an operating method of an optical positioning system including: capturing an image frame of a detected surface, which has interleaved bright regions and dark regions, using a field of view and a shutter time of an optical sensor; counting a number of edge pairs between the bright regions and the dark regions that the field of view passes; calculating an average value of the image frame; calculating a ratio between the calculated average value and the shutter time; determining that the field of view is aligned with one of the dark regions when the ratio is smaller than a ratio threshold; and determining that the field of view is aligned with one of the bright regions when the ratio is larger than the ratio threshold.

摘要： A method of inspecting cased goods includes advancing at least one case of goods on a conveyor, generating an illumination sheet of parallel illuminating rays with at least one electromagnetic source, and capturing an image, formed by the illumination sheet passing through a diffuser with at least one camera located so as to capture illumination from diffused parallel rays of the light sheet, where the image case embodies a goods image that is generated by the case goods moving between the light source and the at least one camera, where part of the parallel sheet of light is at least partially blocked by the case of goods, thus generating a gray level image.

摘要： A shape profile measurement device includes: a light projector and a light receiver arranged facing each other; a belt conveyor for conveying an object for measurement; and a calculation unit. The light projector includes a plurality of light-emitting portions arranged in an array direction, and each emits substantially parallel measurement light. The light receiver includes a plurality of light-receiving portions arranged in the array direction facing the plurality of light-emitting portions, and each receives the measurement light emitted from a corresponding light-emitting portion. The light-receiving portions output a signal indicating a light intensity of the received measurement light. The calculation unit acquires the signal of the light receiver when the object is at a plurality of different movement-direction positions between the light-emitting portions and the light-receiving portions, and obtains a shape profile on the basis of the signal acquired and information relating to the plurality of movement-direction positions.
