Problems solved by technology

[0005] The points fitted by the straight line can better reflect the current direction and distance, but the smoothness and continuity of the trajectory are not ideal
Multi-point curve fitting requires multiple points to fit the curve, such as the existing five-point fitting, which brings a delay of up to two to three frames

Abstract

The invention discloses a trace point frequency improving method based on infrared facula tracking. On the basis that the advantages of an original trace point frequency improving method are guaranteed, trace point motion trial is matched through three barycenter points, the number of facula points required for matching is reduced, meanwhile, smoothness and continuity of the motion trial are reinforced through practical motion characteristics such as motion speed and acceleration speed, and a curve is matched to a real trail in a better mode through a characteristic of imaging of infrared faculae.

Description

technical field [0001] The invention belongs to the technical field of digital image processing, and more particularly relates to a tracking point frequency boosting method for infrared spot tracking. Background technique [0002] The imaging of the infrared light source in the camera image with the filter has the characteristics of stability and easy segmentation, and the infrared light source itself has the characteristics of low cost, long irradiation distance and large angle, which is a good tracking method. Due to the imaging stability of the infrared light source in the image, the tracking algorithm of the infrared light spot formed by the infrared light source is not complicated, and it can run smoothly on the existing hardware platform. [0003] However, when the tracked infrared light spot is used as a control signal, such as an air mouse, because the frame rate captured by the camera itself is usually low, such as 25 frames per second, the output information will c...
