Abstract

The object color identification method comprises the following steps: detecting the position of an object in throwing equipment; when it is detected that the object reaches a preset position, collecting a grayscale image and a color image of the object; correcting the color image according to the grayscale image to obtain a corrected image; and recognizing the color of the object according to thecorrected image. The distance between the object and the image acquisition equipment can be a constant value; therefore, the acquired image does not present different color values along with the change of the distance; the color recognition precision can be improved, the collected images comprise the gray level image and the color image, and the color image is corrected through the gray level image to obtain the corrected image, so that the influence of ambient light can be further reduced, and the detection precision of the object color is improved.

Description

technical field [0001] The application belongs to the field of educational products, and in particular relates to an object color recognition method, device and throwing equipment. Background technique [0002] Scoring is a common item in STEM (Science, Technology, Engineering, Mathematics, Science, Engineering, Technology and Mathematics) education and robotics competitions. In order to improve the diversity of the content of the pitching scoring project, usually the color identification is performed on the dropped balls of different colors, so as to record different scores according to different colors. [0003] In order to identify the color of the thrown ball, a color sensor is usually added to the throwing device, which converts the light of the object to be measured into a photoelectric conversion, and performs color recognition according to the converted electrical signal. Due to changes in the intensity of light, balls of the same color may have different color valu...
