The Texas Instruments Perception Toolkit (PTk) is a software package for accelerating sensing and perception capabilities, particularly for prototyping automotive and robotic applications. Using a combination of sensing modalities commonly used for highly-automated vehicles and machines, e.g., cameras, radar, lidar, GPS, IMU, etc., PTk can help quickly model dynamic environments to facilitate of host of intelligent capabilities from free-space and obstacle detection to path and motion planning.

PTk features a component library of data structures, common sensing and perception processing algorithms, as well as basic routines for visualization, sensor interfacing and data playback. Sample data from an instrumented vehicle and prototype perception applications are also included. PTk provides a cross-platform API that delivers identical behavior on both PC and embedded platforms. In this release, PTk has been integrated with the J7 Processor Software Development Kit (J7PSDK) [Linux Release] for use with the J7 EVM or J7 Pre-Silicon PC Simulator platforms.


The licensing information of this library, as well as any third-party components included which are made available under a number of other open-source licenses are enumerated as part of the manifest. A complete manifest along with export control information is detailed in the table below under "Software Manifest".

Package Versioning

Each package version is composed of 4 period-delimited numbers - represented here by the letters M, m, p and b [M.m.p.b]. The table below provides a descriptive reference regarding package version numbering.

Digit Meaning Description
1 (M=Major) Major revision Incremented when the new version is substantially different from the previous For example, a new module added or an existing module's algorithm significantly altered.
2 (m=minor) Minor revision Incremented when the new version has changed but not in a major way. For example, some minor changes in the API or feature set.
3 (p=patch) Patch number Incremented for all other source code changes. This include any packaging support code.
4 (b=build) Build number Incremented for each release delivery to CM. Reset for any change to M, m or p
