Description

Technical Field

[0001] The present invention relates to the field of image recognition technology, and in particular to a testing method for simulating a target object of an express tricycle using a spray painting technique. Background Art

[0002] Intelligent driving essentially involves the cognitive engineering of attention capture and distraction, encompassing three key components: network navigation, autonomous driving, and human intervention. The prerequisite for intelligent driving is that the vehicle we select meets driving dynamics requirements, and that its sensors can acquire relevant visual and auditory signals and information, controlling the corresponding follow-up systems through cognitive computing.

[0003] The network navigation of intelligent driving solves the problems of where we are, where we are going, which lane on which road, and so on; autonomous driving is under the control of the intelligent system, completing driving behaviors such as lane keeping, overtaking and merging, stopping at red lights and going at green lights, and interaction with lights and horns; manual intervention means that the driver responds accordingly to the actual road conditions under a series of prompts from the intelligent system.

[0004] Image recognition refers to the technology of using computers to process, analyze, and understand images to identify targets and objects of various patterns. It is a practical application of deep learning algorithms. [1] At present, image recognition technology is generally divided into face recognition and product recognition. Face recognition is mainly used in security inspections, identity verification, and mobile payments; product recognition is mainly used in the process of commodity circulation, especially in unmanned retail fields such as unmanned shelves and smart retail cabinets [2].

[0005] The traditional image recognition process consists of four steps: image acquisition → image preprocessing → feature extraction → image recognition. Image recognition software is used by companies like Cognex and others abroad, while domestic companies like Graph Intelligence and Haishen Technology also offer it. In geography, it refers to the technology used to classify remote sensing images.

[0006] Image recognition is very important in the field of intelligent driving. On the road, image recognition technology can identify road conditions and vehicles on the road. Currently, in the method of performing intelligent driving image recognition, simulated vehicles are mostly used for experimental vehicle identification. However, existing simulated vehicles are relatively complex, with high production costs and low production efficiency. Summary of the Invention

[0027] Example 1:

[0028] See also Figure 1-4 The present invention provides a technical solution: a test method for simulating a target object of a courier tricycle using inkjet printing technology. The specific steps of the test method for simulating a target object of a courier tricycle using inkjet printing technology are as follows:

[0029] S1: Build a simulated tricycle frame and spray-paint the tricycle pattern on the simulated tricycle frame;

[0030] The simulated tricycle frame is shaped like the rear of a tricycle. It is made of cardboard or foam. It includes two side panels and a back panel positioned between them. The side panels simulate the sides of a tricycle's cabin, and the back panel simulates the rear of the tricycle. The two side panels are connected to the back panel via a snap-fit ​​connection. The simulated tricycle frame is covered with paper, and the paint pattern is sprayed onto the surface of the paper.

[0031] The tricycle painting pattern includes a tricycle outline pattern and an indicator identification pattern.

[0032] S2: Fixing the simulated tricycle frame with the painted pattern on the free-moving platform, and driving the simulated tricycle frame to move based on the free-moving platform;

[0033] During regulatory testing, the vehicle's visual perception sensor identified the target and obtained the correct distance, and the vehicle's domain controller classified it as a three-wheeled target.

[0034] The free moving platform includes a transverse moving servo slide and a longitudinal moving servo slide. The longitudinal moving servo slide is installed on the saddle of the transverse moving servo slide, and the simulated tricycle frame is installed on the saddle of the longitudinal moving servo slide.

[0035] S3: Conduct relevant regulatory tests. Passing the tests can trigger vehicle functions and meet regulatory requirements.

[0036] The main application here is image recognition. In the field of intelligent driving, image recognition is more important.

[0037] Image recognition is a key area of ​​artificial intelligence. To develop computer programs that mimic human image recognition, various image recognition models have been proposed. For example, the template matching model posits that to recognize an image, one must have a memory pattern of that image from past experience, also known as a template. If the current stimulus matches the template in the brain, the image is recognized. For example, if there is a template of the letter A in the brain, and the size, orientation, and shape of the letter A are exactly the same, then the letter A is recognized. This model is simple and straightforward, and easy to apply in practice. However, it emphasizes that an image must perfectly match the template in the brain for recognition to occur. In reality, humans can recognize not only images that perfectly match the template in the brain, but also images that do not. For example, humans can recognize not only a specific letter A, but also printed, handwritten, misaligned, and different sizes. Furthermore, humans are capable of recognizing a vast number of images, and it would be impossible to have a corresponding template in the brain for every image they recognize.
