Dalsa Sherlock driver

Configuration of the 3DExpress driver for Sherlock (v7.2)

If you just installed a new version of 3DExpress, please follow these steps to install the special acquisition driver for Sherlock:

  1. Open your 3DExpress directory (usually C:\Program files\AQSENSE\3D Express)
  2. Copy the file sherlock_3dexpress.dll to your Sherlock driver directory (usually C:\Program files\Teledyne DALSA\Sherlock\drivers).
  3. Add a reference to it in drivers.ini. Note that since Sherlock v7.2 this file has changed location. You can find it in the 'User Data Directory' drivers (usually C:\Users\username\AppData\Local\Teledyne Dalsa\Sherlock\Drivers). Add a section like this:
    NAME    = 3DExpress
    FILE    = sherlock_3dexpress.dll
    ENABLED = 1

Now sherlock is properly configured, and it will always try to connect to 3DExpress at start.

Quick usage guide

Configure your inputs and outputs with the Configuration menu. Each configured input can produce multiple outputs.

Double clicking in the main grid cells can trigger start/stop of grabbing, and the launching of image viewers for the recent acquired data.

Important details for Sherlock

As Sherlock will try to connect to 3DExpress at start, for a better experience you should always start Sherlock once the 3DExpress server is running.

In 3DExpress, you can use the play/stop buttons for debugging, but once Sherlock is started, Sherlock expects to have exclusive control of the play and stop for the outputs. Notice that it will have the outputs grabbing all the time while in development mode.

Sherlock accepts 8-bit and 16-bit frames, although it shows the latter incorrectly. So, for every output you want to use in Sherlock, you have to configure its Frame output to 8-bits or 16-bits and a fixed size (see section 3DExpress outputs for more information). You can check that the frame output is enabled by checking the Frame column in the Outputs table).

Available Camera Features

With sherlock, you can request currently three features from each camera. These values will be related to the picture previously acquired:
