Embodiment Construction

[0016] Such as figure 1 Shown is an AI (artificial intelligence) flow for a vision application, raw data is collected by an image sensor 100 into a RAW format, processed by an ISP (image signal processing) unit 110 to generate a generally RGB format (R: red, G: green, B: blue) color images are then transmitted to the display unit 120, such as an LED display, for display. The main purpose of the ISP and display is to be pleasing to the eye. In recent years, the collected image data is not only used for human eyes, but also used for AI analysis, thus stimulating a variety of machine vision-based applications, such as autonomous driving, intelligent robots, intelligent monitoring, etc. The output of the ISP is also used as input to the AI ​​unit 130 in most current cases. The functions of the AI ​​unit 130 may include, but are not limited to, object detection, search, indexing, recognition, and the like. Unfortunately, since the main purpose of ISP is for better display, it is...

Abstract

An intelligent vision processing device directly uses raw RAW data from the image sensor for AI processing, not after ISP processing. The present invention describes the processing flow of the original data and the details of the preprocessing method, and compares it with the traditional method. An optional parallel ISP path is available to generate data suitable for display. The present invention enables better results at lower cost and better performance.

Description

technical field [0001] The present invention relates to a technology in the field of machine vision, in particular to a method and system for collecting and processing image data for artificial intelligence, which is suitable for equipment that uses artificial intelligence to process visual information. Background technique [0002] For both the human world and the machine world, vision is one of the most important ways to acquire information. In today's machine vision world, most systems use an image sensor as the front end. Raw sensor output is usually in RAW format, which doesn't match the color response of the human eye. In order to please human eyes, ISP (Image Signal Processing) is used to convert raw data into color data suitable for monitor display and viewing by human eyes, such as RGB data. Unfortunately, ISP conversion may lose some useful information, introduce some wrong information, and add more redundant data to the dataset. As a result, it increases the co...
