  • Patent number: 8773668
    Abstract: A signal processing unit (C1, C2, C3) for processing a light reception signal from an imaging element (12) at different magnifications is provided in a light receiving unit (102) in a displacement sensor (1). This sensor (1) measures a displacement by using light receiving amount data generated by the signal processing unit (C1) for each detection processing by a light projecting unit (101) and the light receiving unit (102), and further adjusts sensitivity for next detection processing. In sensitivity adjustment processing, when a peak value in the light receiving amount data generated by the signal processing unit (C1) approximates to 0, a peak value extracted by the signal processing unit (C2) to which higher magnification is applied is employed. Alternatively, when a peak value in the light receiving amount data generated by the signal processing unit (C1) is saturated, a peak value extracted by the signal processing unit (C3) to which 1-fold magnification is applied is employed.

    Abstract: In a sensor system including a plurality of photoelectric sensor units, a light projecting period arbitrarily determined in each type is provided and mutual interference is prevented between identical types. The sensor system includes the plurality of sensor units coupled by a connector unit while a signal can be transmitted. Each of the sensor units retains type information thereof, and sets a unique identification number by transmitting the signal to each other. Each sensor unit operates after a delay time determined according to the identification number thereof elapses with a synchronous signal as a starting point. The synchronous signal is transmitted with a predetermined period from the sensor unit having a specific identification number in the plurality of sensor units. The delay time of each sensor unit is determined such that an operating period is matched with a predetermined period determined in each piece of the type information.

  • Publication number: 20120303317
    Abstract: Teaching processing using a model of a workpiece is performed by accepting at least one input of a target value for a response time and a tolerance value for a detection error as a parameter representing a condition for a displacement sensor to operate. A CPU during teaching processing determines a maximum exposure time while it causes repeated detection processing by a light projecting unit and a light receiving unit, calculates variation in measurement data of an amount of displacement, and derives the number of pieces of data of moving average calculation suitable for a value for the input parameter as a result of operation processing using the maximum exposure time and variation in measurement data. This number of pieces of data is registered in a memory and used for moving average calculation in a normal operation mode.

  • Publication number: 20100232650
    Abstract: In a measurement apparatus, higher-quality measurement is realized in measurement of measurement object displacement or imaging of a two-dimensional image. In a controller, a light receiving signal of a photodiode is supplied to a displacement measuring unit of a sensor head in order to measure a height of a measurement object, and the height of a surface of the measurement object is measured based on the light receiving signal. Then, in the controller, image obtaining timing is determined based on the height of the measurement object. Specifically, a focus adjustment value corresponding to the computed height of the measurement object is obtained from the table, and an image obtaining signal is transmitted to an imaging device at the timing the focus adjustment value is realized. Therefore, a length between two points on the measurement object is computed from the thus obtained image based on the height of the measurement object.

A control unit 4 extracts a candidate color based on the hue at a maximum point in the hue histogram received from the image processing unit 6. At the same time, the control unit 4 determines a hue threshold value in order to define the range of the color regarded as the candidate color. Furthermore, the control unit 4 extracts all pixels that satisfy the hue threshold value of the candidate color and acquires the value and chroma of the extracted pixel and sets the maximum value and the minimum value in the acquired value and chroma to a value threshold value and a chroma threshold value.
