Detailed Description
The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that any combination of the embodiments or technical features described below can be used to form a new embodiment without conflict.
Example one
In the embodiment, the vial is used as a target object, a label code is arranged on the body of each target object, the label code can be a two-dimensional code or a bar code, various information of the target object, such as production information, use information, positioning information, quality information and the like, is recorded by using the label code, and corresponding information is acquired by identifying the label code, so that a corresponding decision is made.
As shown in fig. 1 and fig. 2, the method of the present embodiment specifically includes the following steps:
step S1: and controlling the transportation equipment to simultaneously transport at least two targets to the acquisition area, and controlling the rotation of the targets while the targets advance.
In this embodiment, the transportation device may be a single-side clamping belt conveyor, and when the single-side clamping belt conveyor transports the object through its single-side clamping belt, the friction force of the clamping belt is utilized to enable the object to rotate in the forward process, and meanwhile, the single-side clamping belt is utilized to avoid the clamping belt from shielding the label code on the side surface of the object, so as to ensure that the image pickup device can clearly photograph the side surface of the object. In addition, the transportation equipment can also be a conveyer belt, a plurality of rotating stations driven by the rotating mechanism are arranged on the conveyer belt, one rotating station corresponds to one target object, and the rotating mechanism is started to drive the target object to rotate in the advancing process of the conveyer belt.
Dividing a partial area of the transportation equipment into acquisition areas, wherein each target object needs to pass through the acquisition areas when advancing in the transportation equipment; the length of a working area of the acquisition area is 200-400 mm, at least two targets can enter the acquisition area at the same time, camera equipment is arranged at a position right facing the acquisition area, and the shooting range of the camera equipment can cover the whole acquisition area, so that the camera equipment can shoot the side positions of the targets in the acquisition area at the same time. The distance between adjacent targets in the acquisition area is maintained at 90-110 mm, and the situation that the targets in the acquisition area are too crowded, so that the adjacent targets are shielded mutually and the acquisition accuracy is influenced is avoided.
Step S2: receiving in-place information sent by the detection equipment, and controlling the camera equipment which is just over against the acquisition area to continuously shoot all the target objects in the acquisition area for multiple times so as to generate a continuous group of pictures.
The acquisition area is provided with detection equipment which can detect whether a target object enters the acquisition area; the detection equipment can be a laser sensor, when a target object enters the acquisition area, laser emitted by the laser sensor is shielded, and when a receiving end of the laser sensor cannot receive signals, the target object is considered to be in place, and at the moment, in-place information is emitted. And after receiving the in-place information, controlling the image pickup device to continuously shoot a plurality of targets in the acquisition area. The number of continuous shooting times of the camera device is equal to the number of target objects entering the acquisition area simultaneously, 10, for example, the acquisition area simultaneously enters four target objects, a stable distance of about 100mm is kept between the target objects, and after the four target objects are in place, the camera device is controlled to shoot forty pictures of the four target objects, the shooting number is increased compared with the traditional shooting number, so that the picture decoding base number is increased, a better decoding effect can be obtained, and the acquisition recognition rate is improved.
Step S3: and sequentially grouping each picture in the continuous group of pictures according to the sequence of the target object entering the acquisition area to generate the display surface picture of each target object.
When forty continuous group pictures are obtained, each picture in the continuous group pictures comprises a local side view of four target objects, and in the process of sequentially grouping the pictures, the local side views at the same position in each picture are extracted according to the sequence of the target objects entering the acquisition area and then spliced to generate a display view of each target object; for example: after the first partial images arranged in each picture are extracted, the partial images are spliced together to obtain a side expansion image of the first-arranged object. Similarly, forty pictures are decoded to obtain the complete surface maps of the four targets.
And in the process of splicing the local images, whether an overlapping area exists between the two local images needs to be judged, if so, the overlapping areas of the two local images are fused and then spliced, so that the situation that the label code is repeated in the display image is avoided, and the identification accuracy of the label code can be improved.
Step S4: and identifying and decoding the surface map of each target object, and acquiring the content of the tag code on the surface map of each target object according to the identification result.
Since the display image of each target object necessarily includes the tag code on the target object, the information recorded by the tag code can be obtained after the display image of each target object is identified and decoded. And a removing device is arranged in front of the acquisition area of the transportation equipment, and the picture identification and decoding process can be completed after the image pickup equipment acquires the picture of the target object and before the picture reaches the removing device. If the identification of the label codes in the display surface image is unsuccessful, the image acquisition or decoding process is failed, and the target object is removed by controlling a removing device; or the label code records the quality information of the target object, and when the quality information of the target object obtained after the identification is unqualified, the rejecting device can be controlled to reject the target object.
In the embodiment, the length of the working area of the acquisition area is closely related to the number of pictures taken by the camera equipment, the shooting quality of the camera equipment and the transportation speed of the target object; generally, the image pickup apparatus has high pixels, a large visual field range and a large working area length, and more pictures are obtained by photographing, but the efficiency and success rate of decoding will be reduced due to the high pixels and the large number of pictures, so that the higher the pixels of the camera, the longer the working area or the faster the speed, and the higher the success rate of recognition. According to the embodiment, through repeated calculation and testing, the length of a 400mm working area and 200 ten thousand pixel cameras are currently adopted as the optimal configuration, the transportation equipment is controlled to transport 150-250 target objects per minute to pass through the acquisition area, under the configuration, four target objects enter the acquisition area at the same time, the camera equipment continuously shoots forty pictures in the acquisition area, namely each target object has forty decoded pictures as a decoding basis, the optimal decoding effect can be obtained, the acquisition and reading rate is improved, meanwhile, the transportation efficiency of the target objects is also improved, and the highest speed of practical application can be realized. Meanwhile, according to different application conditions, different configuration lengths and pixel cameras can be adopted to achieve corresponding purposes.
