It is always necessary to start with the size of the scanned object (X, Y), or you can determine the smallest possible value (d) that you want to distinguish with the camera.

In the task, the distance (D) between the centers of both holes is determined with the measurement accuracy (d). Using these values, we then determine the parameter for selecting the right image sensor and camera.

Object size (O) can be describe horizontally as well as vertically. Some of sensors are square and this problem is eliminated 😊

Each type of application needs a different size of information to solve. This is differentiated by the minimum number of pixels. Let's again use monochrome options.

Underwater Lasers are intended to be used by ROVs (Remote Operate Vehicles) using video images to take general measurements.   By paralleling two laser beams that are calibrated for set distances, accurate measurements from video images are possible.

We looked at the available image sensors and the closest is a model with resolution 3092 x 2080 => 6.4 megapixel image sensor.

Two models of the Sea Beam Laser™ are available and can be customized with green and red diodes or with dots and lines.  This will make the perfect scaler for any underwater application.

For a correct calculation, it is necessary to check the resolution, not only in the horizontal but also in the vertical axis.

Without standards every manufacturer does their own thing and many advantages customers learned to love with the GigE Vision standard would be lost. Like GigE Vision, USB3 Vision also defines:

Rolling shutter: Exposes the motive line-by-line. This procedure results in a time delay for each acquired line. Thus, moving objects are displayed blurrily in the resulting motive through the generated “object time offset” (compare to the image).

Note: The newest rolling shutter sensors have a feature called global reset mode, which starts the exposure of all rows simultaneously and the reset of each row is released simultaneously, also. However, the readout of the lines is equal to the readout of the rolling shutter: line by line.

Laser Tools Co. has the means to integrate and internalize our laser systems into your design to meet your specifications.  This will increase the value of your ROVs.

The machine vision and industrial camera market is offering thousands of models with different resolutions, sizes, speeds, colors, interfaces, prices, etc. So, how do you choose? Let’s go through 5 simple steps which will ensure easy selection of the right camera for your application.

Example: The measuring needs 3 pixels for the necessary accuracy (object detail size d). As necessary accuracy (d) which is 0.05 mm in this example, is imaged on 3 pixels.

How It Works: The Sea Beam™ projects two lines 75mm apart onto underwater objects. This provides a precision scale for size reference when viewed by eye or camera.

Small, handy and cost-effective, USB 2.0 industrial cameras have become integral parts in the area of medicine and microscopy. You can get a wide range of different variants, including with or without housings, as board-level or single-board, or with or without digital I/Os.

We already defined the object size as well as resolution accuracy. As a next step, we are going to define resolution of the camera. It is simple formula to calculate the image sensor.

Note: Each characteristic or application type presupposes a minimum number of pixels. It avoids the loss of information through sampling blurs.

Established interface to GenICam. GenICam abstracts the access to the camera features for the user. The features are standardized (name and behavior) by the standard feature naming convention (SFNC). Additionally, it is possible to create specific features in addition to the SFNC to differentiate from other vendors (quality of implementation). In contrast to GigE Vision, this time the mechanics (e.g. lockable cable connectors) are part of the standard which leads to a more robust interface.

Example: Distance (D) between 2 points with measuring accuracy (d) of 0.05 mm. Object size X = 48 mm (monochrome sensor, because color is not relevant here)

This means the bottom lines of the sensor will be exposed to light longer! For this reason, this mode will only make sense, if there is no extraneous light and the flash duration is shorter or equal to the exposure time.

Note: Monochrome or color?Color sensors use a Bayer color filter, which allows only one basic color to reach each pixel. The missing colors are determined using interpolation of the neighboring pixels. Monochrome sensors are twice as light sensitive as color sensors and lead to a sharper image by acquiring more details within the same number of pixels. For this reason, monochrome sensors are recommended if no color information is needed.
