Embodiment Construction

[0027] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0028] see figure 1 , the specific implementation method adopts the following technical scheme: it uses eight cameras to realize the 360 ​​° observation field of view, uses the matching results of the blurred image collected before and after focusing and the clear image and geometric light path analysis to quickly and accurately locate the target, through Image processing recognizes and locates targets without complex coordinate transformation calculations.

[0029] The eight cameras mentioned above all have an auto-focus function. When the target is recognized, the corresponding camera is triggered to collect two images before and after focusing, and the position of the ...

Abstract

Provided is a multi-camera coordination control and quick precise target identification device. Eight cameras are used for observing a view field by 360 degrees, a matching result of a blurred image and a clear image collected before and after focusing and a geometric optical path are used for quickly and accurately positioning an object, and the object is identified and positioned through image processing. The eight cameras all have an automatic focusing function, after the target is identified, the corresponding cameras are triggered to collect two images before and after focusing, and a matching algorithm in a deigned embedding system and an optical equation are used for calculating the position of the target. An intelligent robot which is provided with a jumping spider imitation visual system has a detection view field close to 360 degrees, and complex calculation of coordinate transformation of a multi-camera calibration coordinate system is avoided through the special target positioning method.

Description

technical field [0001] The invention relates to the technical field of robot bionic vision, in particular to a multi-camera coordinated control and fast and accurate target recognition device of a jumping spider vision system. Background technique [0002] The distribution of the eight eyes of the jumping spider's head under a color scanning electron microscope. The 8 eyes of jumping spiders are arranged in 3 rows. The 4 eyes in the first row are on the vertical plane of the front of the head and chest, the middle two eyes (AME) are particularly large, and the eyes on both sides (ALE) are smaller, all of which have magnetic luster. The second row of eyes (PME) is located on the front and back of the cephalothorax. It is quite small and is often partially covered by hair and is not easy to see. The third column eye (PLE) is often similar in size to the anterior eye. If you connect these 8 eyes with a line, you can see that they form a square or approximately square eye are...
