Problems solved by technology

The advantage of this method is that it is not susceptible to appearance changes, such as lighting conditions, clothing colors, etc.; its disadvantage is that it requires a series of continuous pictures and moving targets, and the real-time performance is not good and stationary pedestrians cannot be identified
The advantage of this type of method is that it can better solve the occlusion problem; and its disadvantage is that the real-time performance is not good, and the detection rate will be reduced due to the difference in the height, fat, thinness, and movement posture of pedestrians.

Embodiment Construction

[0032] The invention will be described in further detail below in conjunction with the accompanying drawings.

[0033] The present invention provides a pedestrian detection method based on multi-feature fusion. The method first uses Kinnect to obtain a depth image, and performs noise reduction processing on the depth image; then realizes the detection of the region of interest based on the method of depth threshold; LBP combines features and implements object detection with SVM classifier.

[0034] A preferred embodiment of the pedestrian detection method based on multi-feature fusion of the present invention specifically includes the following steps:

[0035] Step 1. Use Kinnect to obtain a depth image, and perform noise reduction processing on the depth image.

[0036] (1) The acquisition process of depth imaging is as follows: figure 1 As shown, the specific process is described as follows:

[0037] Calibration; first, at multiple positions away from the light source, us...

Abstract

The invention discloses a pedestrian detection method based on multi-feature fusion. The method includes the following steps that noise suppression is conducted on an obtained depth image; area-of-interest detection is achieved through a depth threshold; on the basis of obtaining the HOG-LBP union features, target detection is achieved through a classifier. According to the pedestrian detection method based on multi-feature fusion, the fused features of the HOG and the LBP are classified through a support vector machine. The method has higher pedestrian representation capacity, and the pedestrian detection accuracy is obvious improved under a complex background.

Description

technical field [0001] The invention relates to a pedestrian tracking method, in particular to a pedestrian tracking method based on multi-feature fusion. Background technique [0002] Pedestrian detection has a wide range of applications in video surveillance, robotics, virtual reality and other fields, and it is also an important research direction in the fields of computer vision and pattern recognition. Different figures, postures, clothing, lighting, complex background scenes, and the movement and shaking of the camera itself are all difficulties in pedestrian detection. How to quickly and accurately detect pedestrians from the video or image background is still a research hotspot. [0003] The current pedestrian detection methods can be divided into the following three categories: pedestrian detection based on motion characteristics, pedestrian detection based on multi-part template matching, and pedestrian detection based on machine learning. [0004] Pedestrian det...
