Title:
METHOD FOR DETERMINING VISUAL DETECTION PARAMETER, VISUAL DETECTION DEVICE AND VISUAL DETECTION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/213971
Kind Code:
A1
Abstract:
Provided are a method for determining a visual detection parameter, and a visual detection device (80) and a visual detection system for determining a visual detection parameter of a target to be detected. The method comprises: acquiring information about a target to be detected, wherein the information about the target to be detected comprises a geometric model of the target to be detected, and the geometric model of the target to be detected comprises a region to be detected of the target to be detected and a non-detection region of the target to be detected (201); respectively determining, according to a first incidence angle, a first reflection angle and a first position and a second position on the geometric model, first reflectivity of the first position and second reflectivity of the second position, wherein the first incidence angle is an angle at which a light source irradiates to the first position, the first reflection angle is an angle at which an image collecting device collects reflected light of the first position, the first position is located in the region to be detected, the second position is located in the non-detection region, and the distance between the first position and the second position is less than a predetermined value (202); determining a reflectivity difference value according to the first reflectivity and the second reflectivity (203); determining whether the reflectivity difference value is greater than a pre-set threshold value (204); and if the reflectivity difference value is greater than the pre-set threshold value, then determining the incidence angle and the reflection angle as a set of target incidence angle and target reflection angle of the region to be detected (205). A target incidence angle and a target reflection angle used for detecting the region to be detected can be determined.
