Abstract: An image stitching method is applied to a camera system with an image stitching function, so as to combine monitoring images captured from different view angles. The camera system includes two image capturing units respectively having a first coordinate system and a second coordinate system, and monitoring regions of the two image capturing units are adjacent and include an overlapped monitoring region. The image stitching method includes detecting at least one moving object within the overlapped monitoring region, calculating at least one set of transforming parameters of the first coordinate system relative to the second coordinate system, acquiring a reliability level according to comparison result generated by mutual comparisons between several sets of transforming parameters and then further comparing with a threshold respectively, determining a final transform parameter by the reliability level, and utilizing the final transform parameter to stitch the monitoring images captured by the two image capturing units.

Abstract: An object matching method is applied to a camera system with an object matching function. The object matching method includes detecting a moving object within overlapped monitoring areas of two image capturing units to generate a first coordinate point and a second coordinate point respectively upon a first coordinate system and a second coordinate system, calculating at least one transforming parameter of the first coordinate system relative to the second coordinate system, acquiring a reliability level according to a comparison result between the transforming parameter and a threshold, determining a final transform parameter by the reliability level, utilizing the final transform parameter to transform the first coordinate point into a third coordinate point upon the second coordinate system, and determining whether the first coordinate point and the second coordinate point indicate the same object by difference between the third coordinate point and the second coordinate point.

Abstract: An image capture system includes a first image capture device, a second image capture device and a processing device, and the processing device is electrically connected to the first image capture device and the second image capture device. The first image capture device is configured to capture a first image, and the second image capture device is configured to capture a second image. The processing device is configured to receive first information transmitted from the first image capture device and second information transmitted from the second image capture device, and determines whether the first image and the second image have a same object based on the first information and the second information. If the processing device determines that the first image and the second image have the same object, the processing device synchronizes timestamps of the first image and the second image according to an event of the object.
