Abstract: A gimbal device for supporting an external photographing device includes a depth camera, a control unit and an actuator. The depth camera is configured to obtain spatial coordinates of a subject being photographed. The control unit is configured to determine a direction adjustment value of the gimbal device according to the spatial coordinates. The actuator is configured to receive the direction adjustment value and to adjust spatial orientation of the gimbal device according to the direction adjustment value, so that the external photographing device is able to track the subject being photographed. The control unit is further configured to obtain initial three-axis data of the gimbal device and three-axis data after the gimbal device is set to determine an angle difference between the initial three-axis data and the set three-axis data, and the actuator is further configured to receive the angle difference.

Abstract: A camera module aligning method includes the following steps. Firstly, a reference chart having plural chart characteristic points is provided. Then, a camera module is used to shoot the reference chart, and an installation position and an installation posture of the camera module are acquired according to an internal parameter matrix and an external parameter matrix. When the camera module shoots the reference chart and an image is formed on an imaging plane of the camera module, a relationship between at least one image characteristic point of the image and the corresponding chart characteristic point complies with a standard relationship. The standard relationship is defined by the internal parameter matrix and the external parameter matrix.

Abstract: A 3D image sensing device includes a first camera lens, a second camera lens and a light source. A 3D image processing method for the 3D image sensing device includes the following steps. Firstly, a target is photographed by the first camera lens and the second camera lens, and the obtained images are processed in a stereo vision mode. Consequently, a first depth map is obtained. After the light source emits plural feature points to the target, the target is photographed by the first camera lens and the second camera lens, and the obtained images are processed in an active stereo vision mode. Consequently, a second depth map is obtained. The first depth map and the second depth map are synthesized as a synthesized depth map according to a synthetization strategy.

Abstract: A security authentication method is provided. In a step (a), a to-be-recognized image information and a to-be-recognized voice information about a user are provided. Then, a step (b) is performed to identify and judge whether the to-be-recognized image information and the to-be-recognized voice information comply with a registered image information and a registered voice information, respectively. In a step (c), if the judging condition of the step (b) is satisfied, a security information prompt signal is generated. In a step (d), a to-be-recognized security information is provided by the user. Then, a step (e) is performed to identify and judge whether the to-be-recognized security information complies with an abnormal warning information. In a step (f), if the judging condition of the step (e) is satisfied, an abnormal state warning and processing process is performed.

Abstract: A method for aligning a camera lens with a light source is provided. The method is used in an aligning system. The aligning system includes an alignment element, a reference camera and a fixture. Firstly, the reference camera shoots a reference chart on the alignment element. Then, the light source is placed on the fixture. The light source illuminates the alignment element to generate an illumination result. The reference camera shoots the illumination result. If the illumination result does not comply with a preset specification represented by the reference chart, the fixture adjusts the light source. Then, the camera lens is placed on the fixture. Then, the camera lens shoots the reference chart on the alignment element to acquire a shooting result. If the shooting result does not comply with the preset specification, the fixture adjusts the camera lens.

Abstract: A method for determining camera module assembling quality is provided. The method includes a step of determining whether the shooting position and the shooting posture of and under-test camera module are correct according to a result of judging whether a relationship between the world coordinate of at least one chart characteristic point of a reference chart and the image coordinate of a corresponding image characteristic point of an image plane coordinate system complies with a standard relationship. Then, the under-test camera module at the correct shooting position and with the correct shooting posture is used to shoot the reference chart. Consequently, an assembling information of the under-test camera module is obtained.
