The Rogue provides access to an impressive list of latest generation interfaces on the Jetson AGX Xavier while adding additional interfaces of 3x USB 3.1, 2x GbE, 2x HDMI and a locking Mini-Fit Jr. power input connector.

Dark field lighting is required to be very close to the part, usually within an inch. The mounting angle of the dark field LEDs needs to be at least 45 degrees or more to create the desired effect (Image 3A).  In short, it has the opposite effect of Bright Field lighting, meaning the surface or field is dark, and the indentations or bumps will be much brighter (Image 3B).

Diffuse light is light that scatters over the crop from all sides. Therefore it is evenly distributed, causing no sharp shadows on the crops.

This Vision Bundle pairs the Rogue Carrier Board with the Allied Vision MIPI Board for a streamlined deployment of AI Vision applications. Empowering rapid integration of your chosen cameras, the Allied Vision MIPI Camera Board allows for direct attachment of up to six MIPI sensors without the need of additional hardware components.

Diffused dome lighting, aka the salad bowl light, works by having a hole at the top of the salad bowl where the camera is mounted and the LEDs are mounted down at the rim of the salad bowl, pointing straight up, which causes the light to reflect off of the curved surface of the salad bowl. It creates a very uniform reflection (Image 5A).  Diffused dome lighting is used when the object you are inspecting is curved or non-uniform (Image 5B). After applying this lighting technique to an uneven surface or texture, hotspots, and other sharp details are deemphasized, creating a matte finish to the image (Image 5C).

Off-axis bright field lighting works by having a separate LED source mounted at about 15 degrees off perpendicular and having the camera mounted perpendicular to the surface (Image 2A). This lighting technique works best on mostly flat surfaces. The main surface or field will be bright, and the holes or indentations will be dark (Image 2B).

This next example (Image 9A) and (Image 9B) was for an application requiring a bar code read through a cellophane wrapper. The unclear image (Image 9A) was acquired using an on-axis ring light, while dome lighting (Image 9B) resulted in a clear, easy-to-read image of the bar code.

Machinevision lightingtechniques

Diffused on-axis lighting, or DOAL, works by having a LED light source pointed at a beam splitter. The reflected light is then parallel with the direction in which the camera is mounted (Image 6A). DOAL lighting should only be used on flat surfaces where you are trying to diminish very shiny parts of the surface to create a uniform image. Applications like DVD, CD, or silicon wafer inspection are some of the most common uses for this type of lighting.

Designed specifically to integrate up to six Allied Vision Alvium 1500 C and 1800 C sensors, this Camera Board comes supplied with all device-tree software necessary to integrate the cameras into your application – no further software development required. With seamless integration to the Connect Tech Rogue Carrier Board, users are able to transition from development to production without additional application development.

On-axis ring lighting is the most common type of lighting because, in many cases, it is integrated on the camera and available as one part number. When using this type of lighting, you almost always want to be a few degrees off perpendicular (Image 1A).  If you are perpendicular to the object, you will get hot spots in the image (Image 1B), which is undesirable. When the camera with its ring light is tilted slightly off perpendicular you achieve the desired image (Image 1C).

Structured laser line lighting works by projecting a laser line onto a three-dimensional object (Image 7A), resulting in an image that gives information on the object's height. Depending on the mounting angle of the camera and laser line transmitter, the resulting laser line shift will be larger or smaller as you change the angle of the devices (Image 7B). When there is no object, the laser line will be flat (Image 7C).

Backlighting works by having the camera pointed directly at the backlight in a perpendicular mount. The object you are inspecting is positioned between the camera and the backlight (Image 4A). This lighting technique is the most robust because it creates a black target on a white background (Image 4B).

Users have the option of integrating either 6x 2-lane or 4x 4-lane MIPI CSI-2 cameras from the Allied Vision Alvium 1500 C and 1800 C camera series.

This example (Image 10A), (Image 10B), and (Image 10C) highlight different lighting techniques on the same object. In the (Image 10A) image, backlighting is used to measure the smaller hole diameter. In the image (Image 10B), dome lighting is used to inspect the upper hole's taper in reference to the lower hole. In (Image 10C) dark field lighting is used for optical character recognition “OCR” on the object. Each of these could be viewed as positive or negative, depending on your goal.

The images below, (Image 8A) and (Image 8B), were used for an application that requires counting the pins of a connector. As you can see, the bright field lighting on the left does not produce a clear image, but the dark field lighting on the right does.

The key to deploying a robust machine vision application in a factory automation setting is ensuring you create the environment for a stable image. The three areas you must focus on to ensure image stability are lighting, lensing, and material handling. For this blog, I will focus on the seven main lighting techniques used in machine vision applications.
