Problems solved by technology

However, the result of the single-camera single-object detection method is that the detection speed is too slow; even if the multi-threading technology that can improve the processing efficiency is used in the program implementation, when there are too many measured objects, the detection of the measured objects will also be slow. Very time-consuming, detection efficiency is still low

Embodiment Construction

[0041] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0042] A method for visual detection of a plurality of measured objects, comprising the steps of:

[0043] S1. Acquiring the location distribution file of the measured object, the location distribution file of the measured object includes location information of a plurality of measured objects;

[0044] S2. According to the measured object position distribution file and using the lens simulation technology to obtain the optimal lens position set, the optimal lens position set is the lens position set that contains all the measured objects and has the least number of lens positions;

[0045] S3. Obtain a corresponding sampled image set according to the optimal lens position set, and process the sampled image set to obtain actual position information of the measured object.

[0046] A visual inspection meth...

Abstract

The invention discloses a visual detection method for a plurality of detected objects. The visual detection method includes the steps of obtaining a detected object position distribution file including the positional information of a plurality of the detected objects, and obtaining an optimal lens position set according to the detected object position distribution file by using lens simulation technology, wherein the optimal lens position set contains all the detected objects and lens positions of lenses of minimal number. The invention further discloses a vision detection system for a plurality of detected objects. An optimal lens position set is obtained according to the detected object position distribution file by using lens simulation technology, and the optimal lens position set contains all the detected objects and lens positions of lenses of minimal number, thereby reducing the moving and positioning frequency required for actual detecting a plurality of detected objects. The visual detection efficiency of a plurality of detected objects is effectively improved.

Description

technical field [0001] The invention relates to the field of visual inspection, in particular to a visual inspection method and system for multiple measured objects. Background technique [0002] refer to figure 1 , figure 1 It is the sampling schematic diagram of the existing visual detection method and the present invention to obtain the optimal lens position set. The object to be tested is used to obtain the image to be detected, and then image analysis is performed on the image to be detected. Only one object to be tested can be detected at a time. Continue to take pictures of the next object to be tested to obtain the image to be detected, and perform image analysis; and so on until the end of the detection. However, the result of the single-camera single-object detection method is that the detection speed is too slow; even if the multi-threading technology that can improve the processing efficiency is used in the program implementation, when there are too many measu...
