  • Patent number: 9483698
    Abstract: A method includes generating a disparity map according to two sets of image data, identifying at least one object in the disparity map, mapping the at least one object onto a plane view, tracking at least one object on the plane view, and providing a robust algorithm about a cross-line time interval and a cross-line degree. The robust algorithm includes detecting whether the at least one object enters a predetermined region when the at least one object crosses a predetermined boundary.
    Type: Grant

  • Patent number: 8610760
    Abstract: A method for intensifying identification of three-dimensional objects identification includes utilizing a left eye camera and a right eye camera to capture a left eye image and a right eye image, calibrating the left eye image and the right eye image to generate a calibrated left eye image and a calibrated right eye image, using the calibrated left eye image and the calibrated right eye image to generate a disparity map, differentiating a three-dimensional object from a background image according to the disparity map, projecting the three-dimensional object onto a plan view, filtering noise out of the plan view to generate a filtered three-dimensional object, determining whether the filtered three-dimensional object contains at least two three-dimensional objects, and separating the at least two three-dimensional objects if the filtered three-dimensional object contains at least two three-dimensional objects.

  • Patent number: 8378855
    Abstract: A control device includes a sensor, an analysis unit, and a control unit. The sensor includes a stationary member and a rotatable member. The stationary member includes a first electrode and at least two second electrodes. The rotatable member includes a third electrode and a fourth electrode. The first electrode electrically contacts the third electrode and each second electrode electrically contacts the fourth electrode in sequence when the stationary member is rotated. The analysis unit is configured for determining which second electrode electrically contacts the fourth electrode. The control unit is configured for executing a corresponding command based upon the determination of the analysis unit.

  • Patent number: 8121400
    Abstract: Comparison of parameters, including width, length, depth, color, and shape of a target object with a reference object is performed through use of a stereo camera. If the parameters of the target object are within threshold values of the parameters of the reference object, a match is indicated. If not, a new reference object is selected for comparison with the target object.

  • Patent number: 7471893
    Abstract: A digital camera has a printed circuit board which comprises a main area and a flexible area. An optical sensor chip (e.g. a CCD) is fixed onto the flexible area. The flexible area has flexible character relative to the main area. Therefore, even if the printed circuit board is stressed, such stress will be almost or completely eliminated in the flexible area, so that the optical sensor chip and an optical lens can be coupled together in a precise manner.
