Abstract
A calibration method of apparatus installation parameter is applied to a surveillance device having an image receiver and an operation processor. The calibration method includes analyzing a detection image from the image receiver to acquire an apparatus installation parameter of the surveillance device, computing a height of at least one target object inside the detection image in accordance with the apparatus installation parameter, analyzing the height of the at least one target object via an error function to acquire an error computed value, computing a local minimal value of the error computed value relevant to the apparatus installation parameter via a gradient descent function, and finding the local minimal value to acquire an installation parameter vector so that the surveillance device executes analysis of the detection image according to the installation parameter vector.
