Embodiment

[0062] This embodiment provides a method for encoding pixel positions on a target surface. The method is applied to a thoracic ring target and includes the following steps:

[0063] Step 1, such as figure 1 As shown in (a), obtain the initial target surface a of the thoracic ring target, and extract the target surface d from the initial target surface a i ,Such as figure 2 ;

[0064] The specific process is:

[0065] Step 11. Because the color of the breast ring target paper has "green constancy", the RGB color space can be selected to extract the green features of the breast ring target paper, and the structure of the breast ring target paper can be initially segmented. In the automatic reporting system, for the segmentation and positioning of the thoracic ring target paper area, the contour parameters of the thoracic ring target area are more important, such as the edge of the contour of the thoracic ring target and the coordinate positions of each corner point. As for the detai...

Abstract

The invention discloses a target surface pixel position encoding method, which is used for a chest ring target, comprising the following steps: obtaining an initial target surface a of a chest ring target, and extracting a target surface d from the initial target surface a i ; against the target surface d i The ring line in is fitted; on the target surface d i In , the position encoding of the target surface pixels is performed according to the fitted ring line. In the positioning of the chest ring target, the present invention adopts the target position recognition technology based on color features, which solves the problems that the target surface in the chest ring target positioning is susceptible to complex background, interference from light changes, and large manual interference, and the positioning accuracy of the chest ring target is high. Human intervention is minimal and undisturbed by lighting conditions.

Description

Technical field [0001] The invention relates to the field of automatic target reporting based on image processing, in particular to a target surface pixel position coding and an automatic target reporting method based on the target surface pixel position coding. Background technique [0002] The acquisition of the initial information of the target surface is the prerequisite and basis for bullet hole identification and determination of the ring number, and determines the performance of the automatic target reporting system. In the traditional automatic target reporting system based on image processing, the work done by the initial information acquisition part of the target surface is only image filtering and image distortion correction. In theoretical research, a relatively regular target paper image can be obtained, but the background interference of the shooting range is not considered The current situation of the target and the sticky target has great limitations in the actual...
