Abstract

The invention provides a detection tracking algorithm optimization method based on a multi-core heterogeneous platform. The method comprises the following steps: firstly, zooming an input 1920 * 1080high-definition image into two output resolution images by adopting a GC620 graphic accelerator, namely a resolution of 300 * 300 and a resolution of 300 * 300 for detection of a detector; 2, zoomingto the resolution of 720 * 576 for tracking on the zoomed image by the tracker. By use of the frame-level pipeline of object detection and the object-level pipeline of target tracking, the calculationefficiency is improved. The cache object information is stored in the on-chip SRAM, so that the calculation efficiency is improved. A multi-core heterogeneous platform is used for carrying out distributed calculation on a filter module on C5 and P6, so that the calculation efficiency is improved. And meanwhile, by utilizing the KCF response value, the calculation requirement of the classificationfilter is further reduced.

Description

Technical field [0001] The present invention relates to a detection and tracking algorithm optimization hardware implementation in the field of deep learning, in particular to a detection and tracking algorithm optimization method based on a multi-core heterogeneous platform. Background technique [0002] The detection and tracking technology based on deep learning is the foundation of various application technologies. For example, applications such as the number of heads in public buses and school buses, face recognition and other applications that are widely used now require detection and tracking technology. However, the existing detection and tracking algorithms have some problems: the calculation is performed on the traditional CPU platform, and the calculation speed is slow, and the detection and tracking may identify and detect non-semantic objects. These problems affect the calculation speed and accuracy of detection and tracking. [0003] How to use a multi-core heterogen...
